Photosynthesis-Justin

2. Answer the following questions on your wiki page:

a. distinguish between autotrophs and heterotrophs in terms of nutrient requirements Autotropic are plant cells, autotrophic means 'self-feeding'. Plant cells that contain chlroplasts are able to produce their own nutrient requirements by photosynthesis. Heterotrophs are animal cells, hetertrophic means ' feeding on something different' animal cells do not contain chlroplasts, they must obtain their needs from their external environment.

b. identify the materials required for photosynthesis The materials required for photosynthesis are carbon dioxide, water and light.

c. identify the role of photosynthesis in ecosystems All living things depend on the process of photosynthesis, this provides the countiuous input of energy nesscary to sustain ecosystems.

d. state what happens in the Light Reactions of photosynthesis

e. state what happens in the Dark Reactions (light independent) of photosynthesis

f. record your answers to the questions on this website: 1. The process of making food in a plant is called

transpiration photosynthesis fertilization

2. Which of these is not needed to make food in a plant?

Sunlight Carbon Dioxide Chlorophyll Flowers

3. The tiny pores or openings in leaves that take in the carbon dixoxide are called

stomata xylem phloem

4. The tubes that bring water from the roots to the leaves are called

stomata xylem phloem

5. The plants give off what that animals need during photosynthesis?

oxygen carbon dioxide chlorophyll

6. The animals breathe out what that plants need for photosynthesis?

oxygen carbon dioxide chlorophyll

7. The sunlight is used during photosynthesis to

Break down the xylem Break down the water Break down the stomata quiz questions

g. research what factors affect the rate of photosynthesis Factors that affect the rate of photosynthesis are: The amount of CO2 that the plant takes in for the process of photosyhthesis Also the intensity of the light the plant recives.
