4. Photosynthesis • In this slide write a description of what you think photosynthesis is based on the diagram and the equation.

5. Respiration

6. Respiration • Respiration is the opposite of photosynthesis. It consumes oxygen (oxidation of sugars) and releases carbon dioxide (CO2) and water. • Respiration is common to all living organisms, whether plants, animals or micro-organisms. Respiration enables both autotrophs and heterotrophs to obtain energy from carbohydrates. This energy is necessary for growth, movement and all vital functions. • The following are a number of factors that affect respiration in plants: • temperature: respiration falls to a minimum at temperatures below 0°C, and is at a maximum at 45-50°C; • the plant's developmental stage : respiration increases during the flowering stage of trees; • the type of plant: respiration is less significant in woody than herbaceous plants. • Plants respire both during the day and at night. However, photosynthesis

9. Transpiration

10. Transpiration • Transpiration is when water travels through a plant. The water moves up the plant from the roots to the underneath of the leaves. Here, the water is turned into vapor and is released by the plant. This process can not be seen by the human eye because the water does not sit on the leaf when it is released. As soon as transpiration takes place, the water evaporates. Over ten percent of the Earth's moisture is caused by transpiration of plants.
