Chapter 7 Flashcards
What process captures light energy from the sun and converts it to chemical energy store in sugars and other organic molecules?
Photosynthesis
What is the general equation for photosynthesis?
water + carbon dioxide + light energy –> glucose + oxygen
Pores in the leaf where carbon dioxide enters
stomata
Where does water enter the plant?
roots
Where does photosynthesis occur?
chloroplasts
What is the structure of a chloroplast
stroma, thylakoid membrane, grana, inner and outer membranes
Where are chlorophyll molecules embedded?
the inner thylakoid membrane
What is the function of plant pigments?
absorb solar energy
Why are leaves green?
chlorophyll molecules absorb violet-blue and red light but reflect or transmit green-yellow light
What is the process of light dependent reactions?
chlorophyl absorbs solar energy and ejects an electron, which is passed down an electron transport chain, and water is split releasing O2
Is carbon dioxide fixed during the Calvin cycle?
yes
What is the product of the Calvin cycle?
G3P which can be used to make glucose
the process that stores energy in the form of glucose
photosynthesis
the process that releases energy from glucose
cellular respiration
