Chloroplasts and Chlorophyll

Question 1

The process by which plants and other photosynthetic organisms trap the sun’s energy and transform it into energy-rich chemical compounds.

Answer 1

Photosynthesis

Question 2

The process by which cells break down high-energy compounds and generate ATP.

Answer 2

Cellular Respiration

Question 3

The direct source of energy for nearly all types of energy-requiring activities of living organisms.

Answer 3

Adenosine Triphosphate (ATP)

Question 4

Photosynthesis takes Carbon Dioxide, Water and Light Energy and produces what?

Answer 4

Glucose and Oxygen

Question 5

Photosynthesis is an example of a ________ pathway
- Synthesis larger molecules

Answer 5

Anabolic

Question 6

Cellular Respiration takes Glucose and Oxygen and produces/releases what?

Answer 6

Produces Carbon Dioxide and Water and releases Energy

Question 7

Cellular Respiration s is an example of a _________ pathway
- Breaks down large molecules into smaller ones

Answer 7

Catabolic

Question 8

During Photosynthesis, energy from sunlight is stored in the bonds of what?

Answer 8

Glucose

Question 9

Plants can convert Glucose into a structural molecule called what?

Answer 9

Cellulose

Question 10

Plants can convert Glucose into ______ storage molecules like starch.

Answer 10

Energy

Question 11

an organelle within the cells of plants and certain algae that is the site of photosynthesis

Answer 11

Chloroplasts

Question 12

What is the inner solution of the Chloroplast called?

Answer 12

Stroma

Question 13

What are the flattened sacs in Chloroplast called?

Answer 13

Thylakoids

Question 14

What are the stacks of Thylakoid in Chloroplasts called?

Answer 14

Grana

Question 15

The molecules that trap solar energy.
- Bound to the Thylakoid membranes
- Gives plants their green color

Answer 15

Chlorophyll

Question 16

What are the two metabolic pathways in Photosynthesis?

Answer 16

Light dependent and Light Independent reactions

Question 17

During Light Dependent Reaction, solar energy is trapped in ________ found in the thylakoid membranes of Chloroplast

Answer 17

pigments

Question 18

Why do leaves look green?

Answer 18

The pigments/chlorophyll absorb almost every color except green, so green is reflected.

Question 19

Main Photosynthetic pigment

Answer 19

Chlorophyll A

Question 20

What pigments are found in leaves?

Answer 20

Chlorophyll A, Chlorophyll B, and B Carotene (carotenoid)

Question 21

B Carotene absorb which lights and are in what colours?

Answer 21

Absorbs Blue and Green, and are yellow, orange, and red in colour

Question 22

Why does the colour of leaves change in the fall?

Answer 22

Chlorophyll masks the other pigments in the spring/summer. Cooler temperatures in fall stop chlorophyll production, revealing the other carotenoid pigments.
