Plant Growth Written Assignment The “Fast Plant” experiment is an observation of a plants growth over the span of twenty-eight days. The objective is to observe how plants grow and use their resources throughout the span of their life. In our lab we observed the Brassica rapa, a herbaceous plant in the mustard family which has a short cycle which makes it a perfect plant to observe in this experiment. Like other plants the Brassica rapa must use the resources in the environment to create energy to complete itʻs life cycle and reproduce. By observing the plant it is easy to see in what organ or function the plant is using itʻs energy and resources and if overtime the resources switch to other part of the plants. By conducting this experiment we are able to observe where and how plants allocate their resources throughout their life by harvesting plants at different points in their life. Every student in a lab section planted eight seeds, two in each cell in a quad, to make sure that we had at least one plant for each week for 4 weeks. After planting the seeds we put the plants on a water mat tray to make …show more content…
Each plant species has a unique pattern of resource allocation that is genetically determined but not fixed. Plants can adjust there allocation pattern when they experience different environments and the presence of other species. Phenotypic plasticity goes hand in hand with resource allocation as well. When a plant has to adjust itʻs resource allocation, sometimes it uses itʻs resources to help the plant grow different characteristic so that the plant can have a greater chance of living in the environment. For example, if a plant from an environment that does not experience wind on the regular basis enters a new environment that has a lot of wind the plant may change itʻs resource allocation and spend more of itʻs resources growing deeper
Many variations and species of plants can be found all around the world and in different habitats. These variations and characteristics are due to their adaptations to the natural habitat surrounding them. In three of many climatic zones, the arid, tropical and temperate zone, plants that vary greatly from each other are found in these locations. In this experiment, we’ll be observing the connection between the adaptations of the plants to their environment at the Fullerton Arboretum. The arboretum is a space containing numerous plants from different environments. The plants are carefully looked after and organized into their specific habitat. Therefore, we’ll be able to take a look at the plants within multiple
It is hypothesized that as plants in small spaces compete for space, the plants compensate by reducing individual stem weight and frequency of bud formation as density increases. This would be intraspecific competition. A factor is density-dependent when it kills more of a population at higher densities and less at lower densities (Stilling 2002). The factor of competition between individual plants of the same species would be considered density dependent.
The Effect of Light on the Organic Plant Elodea Aim: To calculate the rate of photosynthesis from the number of oxygen bubbles produced by the plant. Photosynthesis: The process by which green plants use the sun's energy to build up carbohydrate reserves. Plants make their own organic food such as starch. Plants need Carbon dioxide, water, light and chlorophyll in order to make food; and starch and oxygen are produced. Carbon dioxide and water are the raw materials of photosynthesis.
to this rigid structure of the plants and so, it is very useful as a
As a result of these factors, the flora has adapted to these conditions in a variety of ways including their shape, leaf type, root system, and color. One of the most prominent adapt...
Teacher: “Boys and girls. Yesterday, we took a test about seeds. At the top of the paper it says, “Will the seed grow if it is planted in soil?” Some of you responded all of the seeds would grow, some of the seeds would grow, and none of the seeds would grow. I would like for you to think about the answer you put.
the effect light has on the growth of pea plants. It will take place in an environment with controlled light, with equal amounts of plants being grown in the light and in the dark. All elements of the experiment other than light will be kept the same, such as amount of seeds in each pot, amount of soil in each pot and amount of water given to each plant each day. This will ensure a fair experiment. Prediction: I predict that in general, the plants grown in the light will grow better than those grown in the dark.
The Brassica rapa plants were bred to live in the colder states of America, such as Michigan and Wisconsin. Up there they have very few times it is actually warm enough for plant growth. So to take advantage of those few short moments, Dr. Williams bred a ...
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
The plants of the genus Brassica include species very important for research and agricultural purposes including vital vegetable and oilseed crops (Augustine 2013). Research for these plants typically aim to increase their nutritional value and develop traits such as herbicide tolerance, sterility, and disease and pest resistance (Gupta 2012). One plant that can be used for research is Brassica rapa, in the form of Wisconsin Fast Plants, which are a rapid cycling variety that can be used for genetics investigations (Kinds Plants 2014).
We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth
There were many physical differences between the mutant fast plant and the wild type fast plants. As shown on the graph above, the wild type plants grew bigger and fast tean the mutants. Along with height, the wild type fast plants opened more flowers. For the experimental group, we applied the gibberellic acid on the intersection of the leaves and stems. For the controlled group, the plants had received more water to balance out the amount water given to the experimental group, which was in the acid. We specifically used gibberellic acid to show an increase in plant growth, measuring in centimeters. What surprised us most is that the GA did not have an effect on the Rosette Dwarf plants until week 3. There was an increase of growth towards the end, which raises the question as to why. Why did it take so long? How much time does it take for the gibberellic acid to kick in and affect cell division? It allows us to raise more questions and continue with our
In modern society, living a long life is meaningless since the quality of life is the axis, which defines a happy life. Consequently, drugs and exercises are being continuously developed and the environment is becoming a vital issue. As our method of life is becoming more complex, unexpected accidents happen and diverse lifestyles are causing people to lose their health. Furthermore, there are incidents where individuals lose some functions of the body or have to live an uncomfortable life due to an infection or a disease. Thus, two experiments were held to solve the question of regeneration, in order to recover body functions and strengthening immunity, in order to fight back diseases more successfully. The first experiment was about regeneration of the skin and the
In the lab exercise regarding plant structure and function, we examined slides containing the different kinds of roots (monocot, dicot). We labeled the parts and pointed out the different roles of each in the plant structure. Also, we examined monocot stems and dicot stems in order to familiarize ourselves with its external and internal structures. We sketched and labeled the parts of the stem and looked closely at the positions of each part. In the last part of the lab, we classified leaves into different kinds according to their leaf venation, bases of leaves, and apices of leaves. As an additional exercise, we sketched 20 animals and classified them according to phylum and class. We were also able to discover the scientific and common names of the animals. Overall, the exercises we did enabled us to familiarize ourselves with plant structure thus, gaining a better understanding for plant life and its importance.
To delve into the clockwork of this technology we must start from the beginning. A plant starts its life as a single celled organism; the sperm within pollen fertilizes an egg. This egg (cell) divides to form the tissues and organs of a species. As development proceeds cells grow unique of one another and change. Different cells make up different things (ex cells in the stalk of the plant are much different than those of the piston) and these differences are attributed to the fact the different amounts of proteins in each cell.
