Question

1. in which plant leaf cell type does most photosynthesis take place? 2. in which plant cell organelle does photosynthesis take place? 3. write the overall chemical equation for photosynthesis below. 4. what are the two stages of photosynthesis? a) light reaction b) calvin cycle 5. in which part of the chloroplast does each stage occur? a) b) 6. what gaseous by - product is formed and released during the light - dependent reaction? what two products of the light - dependent reaction are used to power the calvin cycle (light - independent reaction)?

Explanation:

1. Mesophyll cells in plant leaves contain chloroplasts and are the main site for photosynthesis.
2. Chloroplasts are the organelles where photosynthesis occurs, housing the necessary pigments and enzymes.
3. The overall chemical equation for photosynthesis is \(6CO_2 + 6H_2O \xrightarrow{light, chlorophyll} C_6H_{12}O_6+6O_2\).
4. The two - stage answer is already given as light reaction and Calvin cycle.
5. a) Light reactions occur in the thylakoid membranes of chloroplasts. b) The Calvin cycle occurs in the stroma of chloroplasts.
6. Oxygen is the gaseous by - product formed and released during the light - dependent reaction.
7. ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate hydrogen) are the two products of the light - dependent reaction used to power the Calvin cycle.

Answer:

1. Mesophyll cells
2. Chloroplast
3. \(6CO_2 + 6H_2O \xrightarrow{light, chlorophyll} C_6H_{12}O_6+6O_2\)
4. a) Light reaction

b) Calvin cycle

1. a) Thylakoid membranes

b) Stroma

1. Oxygen
2. ATP and NADPH
