9.2 Photosynthesis overview Part 1

During photosynthesis, cells capture the energy of sunlight using

• thylakoid

• stroma

• NADPH

• chlorophyll

Chlorophyll is a type of

• nucleotide

• carbohydrate

• hormone

• pigment

Chlorophyll is found in

• Thylakoid

• Stroma

• Cytoplasm

• DNA

Plants are

• Hetertrophs

• Autotrophs

Which structure in this figure represents a single thylakoid?

• A

• B

• C

• D

Nancy is explaining why chlorophyll is classified as a plant pigment and how it is useful in photosynthesis. Which property of chlorophyll would be most appropriate for her to cite?

• chlorophyll’s ability to absorb light

• chlorophyll’s green color

• chlorophyll’s presence in chloroplasts

• chlorophyll’s reactivity with oxygen

Stuart is listing the changes to matter and energy that occur during the process of photosynthesis. Which of these examples should he include in his list?

• nuclear changes that convert hydrogen and oxygen into carbon

• chemical changes that convert carbohydrates into smaller molecules

• changes that convert light energy into chemical energy stored in carbohydrates

• changes that convert chemical energy into heat and light

Yasmine is asked to describe the structural organization of chloroplasts. She writes the following sentence:

"A chloroplast contains thylakoid stacks, called stroma, that are surrounded by fluid-filled grana."

Which change to the sentence is necessary to make the sentence accurate?

• Replace "grana" with "chlorophyll."

• Replace "stroma" with "chlorophyll."

• Exchange the positions of "stroma" and "grana."

• Exchange the positions of "thylakoid" and "stroma."
