could see that there were different types of plants in either place. Prediction: I think that plants with apical meristems (plants with high points from which they grow) will not survive in the trampled areas, as their high meristems will be damaged. Plants with basal meristems (plants with low points from which they grow) will survive in the trampled area as there meristems are close to the ground so they will not be

Keeping the above described scenario in view, this study will be carried out to establish such protocol for genetically uniform in vitro mass propagation of plantlets from apical meristem of different sugarcane genotypes, which will ultimately reduce the final cost and time of generated plantlets. 2.

transported from the xylem vessel to the phloem sieve tube and back when transporting sucrose from the source to the sink. Lesson 3 7. If you removed the apical meristem from a typical plant, what would be the effect on further plant growth? The apical meristem is what allows the plant to grow in height, vertically. If the apical meristem were to be cut the plant would stop growing taller and would only increase in width as new tissue can no longer be made to increase the height of the plant or length

There are 4 regions in a root tip. The root cap, the meristem, where cell division occurs, the region of cell elongation, where cells become longer and less opaque, and the region of cell differentiation where the difference among the different cell types in the mature root become visible.

elongation of cells. (Campbell, 2008) Each hormone has multiple effects depending on its site of action, its concentrations, and the developing stage of the plant. (Campbell, 2008) Auxin is a plant hormone that is synthesized within the apical meristems and young leaves of a growing plant. Auxin stimulates stem elongation when it is present is low concentrations. It promotes the formations of lateral and adventitious roots, regulates development of fruit, enhances apical dominance, functions in

Abstract: Our group was curious about the stages of the cell cycle in living tissue, generally and specifically in the meristematic cells of the root of garlic and hence considered the duration of the stages of mitosis in relation to the whole cell cycle and compared it to how mitosis was affected after applying petroleum jelly on the garlic root. The first part of the experiment was examining the normal cells of the garlic root and focusing on the shape and cell cycle of those cells. After considering
Aim: The aim of this report is to investigate the responses of plants in regards to growth on the basis of varying directional sunlight. In order analyze this; pea plants will be used within a conducted experiment. Introduction: Introduction to plants: Organisms of all ecosystems rely on the mechanisms that have evolved for the sustainability of survival (Source 7). This is particularly applicable for the Eukaryote Kingdom, Plantae, (plant), of which is sessile. Due to their dormant nature, plants
Chloroplasts Chloroplasts are a group organelles called plastids. The most primitive form of plastids are the progenitor of which, under the influence of sunlight formed chloroplasts. Chloroplasts are oval in shape and size of 3 to 10 nm. They contain photosynthetic pigments, among others chlorophyll carotenoids. Chloroplasts are covered with double cytoplasmic membrane. Inner membrane delimits a space, which is called steep. In the stroma they are flattened membranous vesicles (thylakoid) set on
Observing Mitotic Cell Cycle in the roots of Onion INTRODUCTION The cell cycle refers to sequence of events that takes place in a cell leading to its division and duplication (replication). This process is important to genetics because through the cell cycle genetics information for all sorts are passed from parents to daughter cells. (Griffiths. A et al) A new cell starts after the division and production of two new cells. Each new cell undergoes metabolism, growth and development. At the end of
As discussed by Taylor (1986), tomato is a type of plant from the family of Solanaceae. There are many tomato species around the world. The tomato is not easy to plant in Malaysia and it is also very important as a food for the citizen. This tomato plant is easy to cultivate in area which is in moderate temperature and firstly came from the place which is in dry west coast of tropical South America (Cooper, 1972). According to Picken, Stewart, and Klapwijk (1986), there are several techniques for
Abscisic acid is one of the phytohormones present in plants and was firstly discovered in 1963 by Frederick Addicott and his colleagues (Fursule, Kulkarni, & Agarkar, 2006). It plays an important role in regulating the physiological process especially in extreme conditions, besides plant growth and plant development. Under non-stressful conditions, abscisic acid presents in low levels in plants cells. This is because plant cells require just a low level of abscisic acid for normal growth. In
NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY Biodiversity conservation is about saving life on Earth in all its forms and keeping natural ecosystems functioning and healthy. Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution invasive exotic species, diseases, shifting cultivation, poaching of wild life etc. Since the human beings are enjoying all the benefits from biodiversity
Diverrsity of Plants Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago, trees had evolved and formed forests, within which the diversification of vertebrates, insects, and fungi occurred. Roughly 266,000 species of plants are now living. The two major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes and ferns require free water so that sperm can swim
Introduction Bananas are widely grown in Malaysia as it is highly in demand, it is ranked as the second largest fruit crops produced in Malaysia. Bananas are healthy to be consumed as it contains high vitamins and minerals (Ware, 2014). However, banana production in our country has decreased due to several factors such as the threat of various diseases, high cost of production and lack of diverse planting materials. Jong (2012) mentioned that around 50 % of the banana plantation in Malaysia is cultivated
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
A man (let’s call him Joe) injects an unknown hormone, provided by a veterinarian, into a pecan tree. The following season, the pecan tree produces crop for the first time. Thereafter, the pecan tree produces crop the following seasons without acquiring another hormone shot. Is the crop production due to the hormone shot or other factors? Cattle breeders inject their female cattle (cows) with hormones to help with reproduction for reasons such as fertility and synchronization. With fertility help
The Brown Pigment The brown colour of brown algae is due to presence of green pigment (chlorophyll a and c) and the brown fu-coxanthine. The seaweeds which live in deep water absorb different wavelength of light due to the presence of these different types of pigments and manufacture their food by the process of photosynthesis. Laminarin, a unique type of starch, is produced in brown algae. Examples of Brown Seaweeds 1. Kelp Sea bamboo (Ecklonia maxima), the spilt fan kelp (Laminaria pallida)
Plant Animal Coevolution: A study of herbivore and grass coevolution Introduction Coevolution may be defined as an evolutionary change in a trait of the individuals in one population in response to a trait of the individuals of a second population, followed by an evolutionary response by the second population to the change in the first (Janzel, 1980). Plant animal coevolution is a very broad topic with many different areas and examples therefore this essay will be focused on the evidence of coevolution
nutrients. (Campbell, Reece, Urry, Cain, Qasserman, Minorsky & Jackson, 2008) The root also stores carbohydrates, which is a product used in photosynthesis. (Whiting, D., 2011) The root has a root cap at the tip of the root to protect the apical meristem, which is a tissue in control of the root’s growth. Although it is not visible to the naked eye, the root cap benefits the root greatly. (New World Encyclopedia Contributors, 2004) It generates a greasy substance that acts like a lubricant for
