Blueprint Of Life 1. Evidence of evolution suggests that the mechanisms of inheritance‚ accompanied by selection‚ allow change over many generations * Outline the impact on the evolution of plants and animals of: - Changes in physical conditions in the environment - Changes in chemical conditions in the environment - Competition for resources Physical Conditions | Chemical Conditions | Competition for resources | Change in physical conditions such as:- Temperature- Wind conditions-

be defined as the production of simple sugars from carbon dioxide and water causing the release of glucose and oxygen. The chemical equation for photosynthesis can be expressed as: (light) 6CO2 + 6H2O C6H12O6 + 6O2 (in the presence of chlorophyll) Thus‚ in this experiment‚ we are required to determine the rate of photosynthesis of leaf disc. But first‚ we must know that‚ the rate of photosynthesis and the amount of oxygen produced by a plant is affected by different factors such

and acting much like lysosomes in animal cells. They regulate the pressure in the cell and collect water to keep the plant from wilting. Chloroplasts are specialized organelles fond in all higher plan cells. Those organelles contain the plants chlorophyll which is responsible for the plant green color. The cytosol is the soup like liquid that all other organelles reside in and where most of the cellular metabolism occurs. Lastly the cell

Plants release oxygen into the atmosphere as a by-product of photosynthesis b. Photosynthesis c. Definition- The process in which green plants use the energy from the sun to make carbohydrates from carbon dioxide and water in the presence of chlorophyll 5. Steps to the photonthesis a. Planets pull the carbon off the CO2 and use the carbon in glucose. The plants do not need the oxygen for this because they get it from the water. b. Plants release the oxygen (o2) back into the atmosphere. c.

are mostly parasites and also symbionts. Mushrooms‚ mold and mildew are all examples of organisms in the kingdom fungi. The kingdom of the plants is the second largest kingdom. The plants are very complex multicellular organisms. They contain chlorophyll‚ which helps them prepare their own food by the process of photosynthesis in which plants convert energy from sunlight into food. This kingdom includes all types of plants like herbs‚ shrubs‚ trees‚ flowering and non flowering plants. The biggest
