Introduction Asexual propagation is the process through which reproduction without passage through the seed cycle occurs. The advantages of asexual propagation are that it preserves genetic makeup, propagates seedless plants, disease control, rapid production, the plants are identical, cheaper, faster and easier reducing or avoiding juvenility. The disadvantages of asexual propagation are that it increases disease and insect susceptibility, plants are bulky, and the mother plants could become contaminated

Have you ever seen a plant leaning towards a window? Have you ever seen the roots of a plant sticking out of the bottom of a potted plant? By researching the properties of phototropism and gravitropism, and the interactions of the two tropisms, one will be able to learn about how they impact each other. Research will provide information on which of the two tropisms exhibits a more dominant effect on plants. Performing experiments are necessary for conclusions to be drawn. Tropism is the direction
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
and the lower surfaces of its leaves. Experimental hypothesis Taking into account the relative background scientific Information, it is expected to be proven that the rate of transpiration from a leaf of a plant is proportional to the number of stomatal pores on the surface of that leaf. Null hypothesis Negative results would be to establish that the transpiration rate is inversely proportional to the number of stomatal pores or is not affected by it whatsoever. Introduction
of spinach leaves. I pulled the plunger completely out of the syringe and put the leaf circles into the syringe. Next I pushed the plunger back in. I used the syringe to suck up the baking soda water until the syringe was about ¼ full of liquid. I placed my finger over the end of the syringe and pulled back on the plunger as far as I could without pulling the plunger out. I repeated this step three times. All the leaf circles sunk to the bottom of the liquid. I placed the spinach into a clear glass
1.1.7. Morphology Chickpea is an herbaceous annual plant which branches from the base. It is almost a small bush profusely branched, erect or spreading, reaching a height of 0.2-1 m, appearing glandular pubescent, olive, dark green or bluish green in color. Leaves are imparipinnate, glandular-pubescent with 3-8 pairs of leaflets with rachis ending in a terminal leaflet. Leaflets are ovate to elliptic, 0.6-2.0 cm long, 0.3-1.4 cm wide; margin serrate, apex acuminate to aristate, base cuneate; stipules
Diverse Australian Biomes Adapting Australia is a land of rather extreme weather conditions and widely diverse climates that force the vegetation living there to adapt in many interesting ways. Australia is the driest continent, and biomes such as grasslands and savannas are prime sources of widespread catastrophic fires. The plants that grow in the vast arid and semi-arid regions of Australia are prone to fires simply because of the desert climates that they grow in. High temperatures combined
An Analysis of Mending Wall The speaker of Mending Wall allies himself with the insubordinate energies of spring, which yearly destroy the wall separating his property from his neighbor's: "Spring is the mischief in me," he says (CPPP 39). This alliance at first has the effect of setting the speaker against the basic conservatism of his neighbor beyond the hill, who as everybody knows never "goes behind his father's saying": "Good fences make good neighbors." But the association of the speaker
Investigating the Effect of Light Intensity on the Size of a Plantain Leaf Title: To investigate the effect of light intensity on the size of a plantain leaf. Hypothesis: I predict that the size of the plantain leaves would increase as the light intensity decreases. Therefore, plantain leaves found in the shade will have larger surface areas than leaves found in an open area. Theory: Sunlight is an essential factor need to complete the process of photosynthesis. Photosynthesis consists
floating leaf disk assay technique works well for doing labs. For this experiment you will need baking soda, a plastic syringe, leafs, hole punch, plastic cups, dilute liquid soap, timer and a light source. Prepare 1/8 of a teaspoon of baking soda and 300 ml of water. The baking soda acts as an alternative source of carbon dioxide for photosynthesis. You then add 1 drop of dilute soap to the solution, the soap wets the outside of the leaf allowing the solution to be drawn into the leaf. Avoid having
shining upon the leaves. During our experimentation, there were moments in time where the sun was hidden and the sun was shining brightly. Therefore, possibly affecting the color of our leaf color. The sunlight may cause our leaf to look lighter than they possibly are. This could cause false information to compare the leaf colors for each biome. To improve my procedure, there are plenty of different ways to do so now that I have an increased experience with working with a large selection of trees. A
Lemna Coursework Introduction Lemna are small water plants found in ponds. Typical of plants, they reproduce asexually. When they reproduce they form a bud on the edge of a leaf, which, when big enough, will eventually separate from the mother leaf and can then reproduce itself. Sometimes lemna plants can have up to 3 or 4 buds. Exactly the same as plants in soil, they use the sun's energy for photosynthesis, and water, but they have to take all their nutrition to grow and reproduce
folded against the chin, with the all too familiar look of complete confusion and bewilderment, as he tried to understand what it was exactly that the prehistoric female wanted (or perhaps how to trick her into scampering off with him to his little leaf-filled bed to reproduce). The female, on the other hand, having easily deciphered the mind of the opposite sex, could be found with a similar expression trying to figure out what was so difficult for the male species to comprehend. Why was it so
certain clues about what Odysseus feels his homecoming should (but not neccessarily will) be like. First of all, Odysseus wants to return to Ithaka. Homer goes as far as having Odysseus describe Ithaka: "There is a mountain there that stands tall, leaf-trembling Neritos, and there are islands settled around it, lying one very close to another. There is Doulichion and Same, wooded Zakynthos, but my island lies low and away, last of all on the water…" (Bk. 9, ln. 21-25). Kalypso lives on island, which
and Pagiophyllum. The two genera closely resemble one another in foliar morphology. However, combined transmitted light and polarizing microscopic observations together revealed additional characters such as the pattern of leaf arrangement, cushions and keel size, shape of leaf apices and bases. Since cuticular are not preserved, specimens are assigned to their genus level only. Both specimens have leafy axes with imbricate, spirally arranged scale like leaves. This indicates their affinity to

Introduction Many scientists in the past, such as Aristotle and Plato, believed that there were no changes in populations; however, other scientists, such as Darwin and Wallace, arose and argued that species inherit heritable traits from common ancestors and environmental forces drives out certain heritable traits that makes the species better suited to survive or be more “fit” for that environment. Therefore, species do change over a period of time and they were able to support their theory by
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
