Photosynthesis |
Autotrophic organisms (plants, algae, cyanobacteria) transform light energy to chemical energy. |
|
|
|
CO2 and water |
The process of photosynthesis starts with what? |
|
|
|
Chloroplasts |
Light absorbing organelle where photosynthezis occurs in plants and green algae |
|
|
|
Chloroplasts |
Where does photosynthesis occur? |
|
|
|
Chlorophyll |
Green color comes from pigment _____ (absorbs all light but green wavelengths) whoch capture the light energy from the sun |
|
|
|
Stomata |
pores on leaves and other surfaces through within CO2 eneters and O2 exits |
|
|
|
Stroma |
Thick fluid filling inner compartment |
|
|
|
Thylakoid membrane |
Interconnected membranous sacs inside stroma; form sacks called grana |
|
|
|
Thylakoid membrane |
Chlorophyll molecules are located where? |
|
|
|
Co2 and water |
Starting molecules of of photosynthesis are waste products from cellular respiration which are? |
|
|
|
Glucose and o2 |
Waste products from photosynthesis are what respiration uses to begin which are? |
|
|
|
Light reaction, calvin cycle |
Two-step process of photosynthesis? |
|
|
|
Thylakoid membrane |
Where does light reaction take place? |
|
|
|
Light reaction |
Chlorophyll absorbs light energy and converts to ATP and NADPH |
|
|
|
Stroma |
Where does calvin cycle take place? |
|
|
|
Calvin cycle |
Uses products from light reactions to make sugar from CO2 |
|
|
|
Wavelength |
The distance from one wave light to the next is? |
|
|
|
Chemical energy |
Chlorophyll converts solar energy to what? |
|
|
|
Pigments |
This are light absorbing molecules; found in many types of cells, not just photosynthesizing ones. |
|
|
|
Thykaloid membrane |
Chloroplasts contain several pigments, built into where? |
|
|
|
Chlorophyll a, chlorophyll b, carotenoids |
3 types of pigments in the chlorophyll |
|
|
|
Chlorophyll a |
Participates directly in light reactions; absorbs blu-violet and red |
|
|
|
Carotenoids |
Some pass their energy to chlorophyll a, others are protective and absorb rays that could damage chlorophyll. Absorbs blue-green |
|
|
|
Chlorophyll b |
Does not participate in light reactions but conveys its energy to chlorophyll a; absorbs blue, orange |
|
|
|
Photosystems |
Cluster of pigments organized into light harvesting complexes; act like light gathering antenna |
|
|
|
Photons |
A fixed quantity of light energy; shorter the wavelength the greater the energy |
Light energy, electromagnwtic energy |
|
|
C3 plants |
Co2 from air starts calvin cycle; first organic compound is three carbon molecule |
|
|
|
C3 plants |
Strategy of closing stomata when dry and hot stops sugar production. |
Oats, wheats |
|
|
C4 plants |
Co2 made into four carbon compound that enters Calvin cycle. Stomata mostly close |
Corn, sugarcane |
