PLANTS AND HUMAN BEINGS Plants and humans are living things that constitute part of the environment. These two depend on each other for their survival. But as plants can live without humans‚ humans can not live for long without plants and this essay explains why this is possible. Plants have the capability to build up organic substances they need from inorganic substances. They only need carbon dioxide‚ water and salts to make their essential substances. Glucose for example is produced from these

Transgenic Animals and Plants What is a transgenic animal/plant? A transgenic animal or plant is one that has a foreign gene (called a "transgene") inserted into its DNA. Transgenic animals and plants are sometimes called "genetically modified organisms" or GMO ’s for short. What is a transgene?

The C4 & CAM Pathway Many plant species that evolved in hot‚ dry climates fix carbon through alternative pathways. Under hot and dry conditions‚ plants can rapidly lose water to the air through small pores called stomata. Stomata (singular‚ stoma)‚ are usually located on the undersurface of the leaves. Plants can reduce water loss by partially closing their stomata when the air is hot and dry. Stomata are the major passageways through which CO2 enters and O2 leaves a plant. When a plant’s stomata are
