They go into the leaf’s veins and from there to all parts of the plant.

Question 12

5. What is the produced as a waste product of photosynthesis?

Answer 12

Oxygen

Question 13

*****Why are the leaves important for photosynthesis?

Answer 13

They capture the sunlight

Question 14

Answer 14

From the roots

Question 15

What is the tissue called that carries the water to the leaves of the plant?

Answer 15

Xylem

Question 16

What is the function of the stomata?

Answer 16

They open and close to let in and give off the gases carbon dioxide and oxygen.

Question 17

Who does the job of opening and closing the stomata when needed belong?

Answer 17

The two guard cells that surround them

Question 18

Where are the chloroplasts of the cells located?

Answer 18

Underneath the epidermis

What is the outermost layer of the leaf?

Answer 19

Epidermis

Question 20

Inside the chloroplasts, what is combined in the presence of light energy and makes what?

Answer 22

Starch

Question 23

During photosynthesis, plants produce sugar in the form of what?

Answer 23

Carbohydrate

Question 24

**What are carbohydrates used for?

Answer 24

Energy stored as food and new structural materials.

Question 25

*****What are sugars stored as?

Answer 25

Starch

Why is photosynthesis important for animals?

Answer 27

It’s their source of energy.

Question 28

*****What are the two ways animals use photosynthesis?

Answer 28

1. When an animal eats a plant, it takes in the carbohydrates stored in the plant.
2. Breathing oxygen

Question 29

After the plants and animals get the energy they need from carbohydrates, it is released during what?

Answer 29

Cellular respiration

Question 30

When is the energy in carbohydrates released?

Answer 30

When the cells of organisms use oxygen to break down the sugars

Question 31

Photosynthesis and Respiration are what of each other?

Answer 31

Opposite

Question 32

Where does cellular respiration occur?

Answer 32

In Mitochondria

Question 33

Oxygen and sugar produced during photosynthesis do what?

Answer 33

Enter the cell and go into the mitochondria.

Question 34

Answer 34

Break down the stored carbohydrates to release energy.

Question 35

The released energy is changed into a substance called what?

Answer 35

ATP

Question 36

What is ATP?

Answer 36

ATP is like a battery that goes where the cell needs energy. ATP is constantly being charged.
