micronutrients necessary for growth of plants. Some of these are explained below: Manganese- Functions with enzyme systems in the plant which are involved in breakdown of carbohydrates‚ and nitrogen metabolism. Iron- Essential for formation of chlorophyll. Zinc- Regulates the consumption of sugar in the plant (sugar=energy!) Boron- Aids production of sugar and carbohydrates Copper- Important for reproduction of plant- ie fruit and flowers Molybdenum- Helps the plant capture nitrogen

Aim: To investigate the effect of one environmental factor on the phenotype of pea plants Background Information: Pea seeds are available with identical genetic information for height - tall or dwarf peas. These seeds can be used to demonstrate the effect of the environment on the final height of the pea plants. Tall or dwarf peas can be grown in identical conditions where all variables are kept constant apart from one environmental factor. Any differences in the height of the pea plants will be

Chemically‚ over 100 compounds have been identified in smoke [9]. Of those that have been identified‚ many are known to have physiologically effects on plants‚ including NO2 [10]‚ CO2‚ SO2‚ and O3 [11]. O3 has been linked to the destruction of chlorophyll [12] and has also been shown to inhibit the K+ channels that regulate guard cell function and in turn controls stomatal opening [13]. SO2

PROTIST STUDY GUIDE 1. Where can Protists primarily be found? Most Protists can be found in wet areas‚ tree trunks and other organisms 2. What niche do Protists fill in an ecosystem? Protists have a big role in marine life‚ it serves as housing for many animals and food for many as well. 3. What are the 3 categories of Protists? Animal-like protists plant-like protists and fungus-like protists 4. What are the 4 types of Protozoa and how does each one move? Ciliates : Have hundreds of

called nuclear fusion. Every second‚ the Sun emits vast amounts of energy‚ much of which is light‚ and this solar radiation can be converted into electricity. Plants and trees are pretty good at collecting this energy. With the help of green chlorophyll‚ they use light energy to make food – they’re our solar powered food factories. But how can we copy them? Scientists and engineers are working on ways to do this and have developed photovoltaic cells‚ or PV cells for short‚ that can turn sunlight

Plant Cells have cell walls‚ which makes them appear rectangular or square in shape‚‚ plant cells have chlorophyll the light absorbing pigment required for photosynthesis. First‚ animal cells don’t have central vacuoles or cell walls. Cell Walls are composed of cellulose‚ hemicellulose and other material Animal cells do not have cell walls they only have a

change of your food diet you might make your dream-come-true. There are lots of advantages of having a vegetarianism diet. Vegetarianism is good for health‚ saves nature and lives. Vegetarianism is good for health. Vegetables provide people with Chlorophyll and phosphorus. Also vegetables provide vitamins for humans. A meal with vegetables and fruits makes you healthy. When people who eat meat die of heart disease‚ vegetarians don’t. When vegetables and fruits come inside our body they get rid of radicals

Cell Wall- The cell wall is a rigid structure outside the cell membrane that supports and protects the cell. The cell wall is made of tough cellulose fibers and other materials made by the cell. Analogy- In a restaurant the building itself supports the restaurant. It is often made of wood or concrete. Cell Membrane- The cell membrane is a structure that forms the outer boundary of the cell and allows only certain materials to move into and out of the cell. Food‚ oxygen and water move into
