Higher Biology Unit 3.2 Photosynthesis part A

What is the pigment in chloroplasts that performs photosynthesis?

• Chlorosynthesis
• Chlorophyll
• ADP
• Electron Transport

Which organelle from the plant cell is primarily responsible for converting sunlight to energy?

• Mitochonria
• Nucleus
• Vacuole
• Chloroplast

Why does the rate of photosynthesis decrease at high temperatures?

• Enzymes are denatured

• Enzymes do not have enough kinetic energy

The second stage of photosynthesis is called

• Light Reactions

• Carbon Fixation

During Stage 1, water is split in order to produce....

• Hydrogen and Oxygen

• Hydrogen and Carbon Dioxide

• Water and Hydrogen

• Oxygen and Water

Sugar can be converted into which building material?

• Fat

• Starch

• ATP

• Cellulose

What are grana?

• structures in the cytoplasm of all cells

• site of carbon fixation stage in plants

• stacks of sacs where light stage happens

• liquid filled area in chloroplast

Why do leaves look green?

• green light is absorbed

• green light is reflected

• green light is reflected and transmitted

• pigments in plants are all green

Which pigment absorbs dark blue and red light?

• chlorophyll a

• chlorophyll b

• carotenoids

• all of the above

The rate of photosynthesis in different wavelengths is called the:

• absorption spectrum

• action spectrum
