3.

What conclusion can be drawn about respiration based on the chart shown.

a)

Plants release more gas when they are closer to light

b)

plants release less gas when they are closer to the light

c)

the plant that is 40 cm from the light makes the most bubbles

d)

plants release more gas when they are far away from the light

4.

What is the role of stomata during photosynthesis?

a)

allow oxygen into the leaf and to release carbon dioxide

b)

allow carbon dioxide into the leaf and release oxygen

c)

allow water vapor into the leaf to make sugar

d)

release water from the leaf

5.

The image shows the opening and closing of the stomata. What structure is responsible for opening and closing the stomata?

a)

guard cells

b)

xylem cells

c)

guard chloroplast

d)

chlorophyll

6.

Which of the below is not true of photosynthesis?

a)

some of the sugar is turned into other compounds, such as cellulose

b)

some of the sugar is stored in the plants cells for later us

c)

the waste product carbon dioxide is given off through tiny openings in the underside of the leaf

d)

the products are used by both plants and animals

7.

For transpiration to occur, what part of the leaf must be open in to allow the release of excess water?

a)

guard cells

b)

roots

c)

stomata

d)

xylem

8.

Martha was trying to identify a weed in her garden. She made the following observations about the weed listed below. Which of her observations supports the inference that photosynthesis can take place in the weed she found?

a)

it had a smooth stem

b)

it had a rough, dry texture

c)

it was green in color

9.

Plant cells lose water through transpiration. Which of the following processes keep the plant from drying up completely?

a)

stomata release water vapor

b)

guard cells open the stomata

c)

the stomata take in oxygen

d)

guard cells close the stomata

10.

Plants take in carbon dioxide through openings in their leaves known as________.

a)

guard cells

b)

xylem

c)

stomata

d)

chloroplasts

11.

Cacti live in a very dry environment and need to store water that they are able to collect. Which explanation best describes a catus?

a)

stomata would be closed during the day to prevent water loss and open at night to allow the entry of needed gases.

b)

stomata open and close whenever they want.

c)

during the day they keep their stomata open so they don't lose water and closed at night because the temperature is cooler.

12.

What are the outputs of photosynthesis?

a)

Sunlight, carbon dioxide and water

b)

sunlight, oxygen and glucose

c)

glucose and oxygen

d)

energy, oxygen and carbon dioxide

13.

Water being absorbed by the roots, pulled up to the leaves and then released into the air through the stomata is an explanation of what plant process?

a)

transpiration

b)

condensation

c)

photosynthesis

d)

respiration

14.

a)

mitosis

b)

respiration

c)

photosynthesis

d)

transpiration

15.
