The plant tissue that carries food materials DOWNWARD from the leaves to the rest of the pant is the ______.

Phloem

Stomata

Chlorophyll

Xylem

Vascular tissue that transports water and minerals UPWARDS from a plant's roots is know as ______.

Chlorophyll

Phloem

Stomata

Xylem

what is the function of root hair?

it is place to store the food

it has large surface area to absorb more water

How do water enter the roots from the soil?

diffusion

osmosis

transpiration

active transport

Water vapour exits a plant leaf by

the stomata

the epidermis

the palisade cells

the spongy mesophyll

Transpiration is

the movement of water through a plant from the roots up the stem

the loss of water from the leaves of a plant by the process of evaporation

the flow of water into plant roots by osmosis from the soil

the process of minerals and sugars moving through plant veins

Why is the evaporation of water from leaves important?

It cools leaves and helps move water up the plant.

It makes the plant wilt

It helps the plant to respire

Where is xylem found in the plant?

leave -> roots -> stem

roots -> stem -> leaves

root hairs -> leaves -> veins

stem -> roots

What do the guard cells do?

Control active transport

Control nutrients moving into the cell

Controls the rate of transpiration (loss of water through the leaf)

10.

What does phloem transport?

Water

Minerals

Fruit

Sugar

11.

What is the main factor that influences the rate of sugar transport?

movement of water

Rate of photosynthesis

capillary action

uprooting plants

12.

Where does sugar transport begin?

Roots

Leaves

Root hairs

Vascular bundles

13.

Xylem vessel elements are strengthened by

lignin

cellulose

melanin

pericycle

14.

How will lowered humidity affect the rate of transpiration?

decrease it

increase it

no change

it depends

15.

An increase in wind or temperature will ________________ transpiration

increase

decrease

no change

none

16.

The rate of translocation in the phloem was observed to decrease steadily after a plant was placed in an environment without oxygen for several minutes. Why did this happen?

The cells in the plants stop respiring.

The xylem no longer takes in water for the plant.

Active transport of mineral salts can no longer occur.

The plant can no longer synthesize sugars to provide energy.

17.

The equation for photosynthesis is

oxygen + water --> glucose + carbon dioxide

oxygen + glucose --> carbon dioxide + water

carbon dioxide + water --> glucose + oxygen

carbon dioxide + glucose --> oxygen + water

18.

Why does temperature have an effect on the rate of photosynthesis?

Higher temperature allows carbon dioxide to diffuse into the leaves faster.

Higher temperature allows water to be transported to the leaves faster.

Higher temperature allows the stomata to open wider.

Higher temperature allows the enzymes to function better.
