Topic 9: Plant Science 9.1 Plant Structure and Growth 9.1.1 Draw and label plan diagrams to show the distribution of tissues in the stem and leaf of a dicotyledonous plant. Cross-section of a stem Part of plant | Purpose | Epidermis | Surface of the stem made of a number of layers often with a waxy cuticle to reduce water loss | Cortex Tissue | Forming a cylinder of tissue around the outer edge of the stem. Often contains cells with secondary thickening in the cell walls which provides

Research Project: The Effect of Calcium on Plant Growth Problem Statement What affect do various amounts (0 mg‚ 300 mg‚ 600 mg) of Calcium added to Vigna unguiculata (black eyed pea plants) once a week have on the overall growth (height‚ number of leaves‚ number of pods) over a 30 day period of time? Research Hypothesis If various amounts (0 mg‚ 300 mg‚ 600 mg) of Calcium are added to Vigna unguiculata (black eyed pea plants) once a week‚ then those plants receiving 300 mg of Calcium will have a

Speech 1-Propagation Anyone with money can purchase plants‚ but part of the fun of horticulture is to start your own. That is where Propagation comes in‚ it is the reproduction of the parent plant‚ using several different methods. There are five methods of propagation‚ seeding‚ cutting‚ division‚ grafting‚ and layering. The most difficult form of propagation is grafting. A lot of people probably think this is dumb or boring‚ but I think it is neat. Most people think the only way to grow plants is by

composition of medium for the tissue culture is the most important key factor in the successful culture of plant cells. The medium should be accurately defined of inorganic and organic chemical additives so as to provide i) the nutrients for the survival of the plant cells‚ tissues and organs under culture and ii) the optimal physical condition of pH‚ osmotic pressure‚ etc. In the culture of plant cells formulating optimum type of medium favorable for in vitro culture was achieved many years ago

Describe how the uses of plant fibres and starch may contribute to sustainability How can plant fibres be used? First of all the plant fibres have to be extracted from the plant itself. The process of extraction often used is called retting. Retting involves using water or micro-organisms to dissolve or rot away the cellular tissues surrounding the bast-fibre bundles. Afterwards the fibres are obtained; usually they extract very long sclerenchyma cells and xylem tissue because of their good

What pH Level Causes a Plant to Grow Best Alexis Chavez‚ Heather Nutt‚ Nguyen Phan Introduction We knew that water is normally stated as the best form of liquid to make sure plants grow as best as they can‚ but we wanted to know if causing the water to be more basic or more acidic would affect how the plant grew. Our hypothesis was that if the plant is treated with a pH of 12 then treated with another pH. Materials The materials used were three identical plants‚ that each had 4 sections that were
