process that captures energy from the sunlight to make sugars that store chemical energy.
a molecule in chloroplasts, that absorbs some energy in visible light.
stacks of coin-shaped, membrane enclosed compartments needed for photosynthesis.
light- dependent reactions
capture energy from sunlight and take place within and across the membrane of the thylakoids.
light- independent reactions
use energy from the light-dependent reactions to make sugars. They occur in the stroma of chloroplasts.
What are the roles of chloroplasts and chlorophyll in photosynthesis?
Chloroplasts contain a light absorbing molecule called chlorophyll and this is the place in plants where photosynthesis takes place.
Describe the stages of photosynthesis?
(light-dependent reactions capture the energy from the sunlight)
1. Energy from sun is absorbed & oxygen is released (in the chloroplasts)
2. energy transfers to molecules that carry energy like ATP (across the thylakoid membrane)
(light-independent reactions use the energy to make sugars)
3. Carbon dioxide molecules area used to build sugars (Energy from light-dependent reactions is used)
4. simple sugar molecules are formed.
Suppose you wanted to develop light to help increase plant growth. What characteristics should the light have?
energy for ATP
Explain why photosynthesis is important for building the structure of plant cells?
Plants need glucose(sugars) to build starches and molecules for their growth and development.
