☀️Plant Transport

Question 1

Autotroph

Answer 1

Makes own food

Question 2

Why do plants need a support system

Answer 2

To provide materials needed for various plant metabolism processes

Question 3

Metabolism processes

Answer 3

Photosynthesis
Respiration
Growth
Reproduction

Question 4

Materials transported in plants

Answer 4

Water
Carbon dioxide
Minerals

Question 5

What does water enter the roots by

Answer 5

Osmosis

Question 6

Adaptions of water uptake by roots diffusion

Answer 6

How does water move from root hairs to ground tissue

Question 7

2 mechanisms combine to cause upward movement of water through the stem in the xylem

Answer 7

Root pressure

Transpiration

Question 8

Root pressure

Answer 8

As Water moves up the root by osmosis it builds up a pressure that pushes water up the water into the xylem

Question 9

Transpiration

Answer 9

Loss of water from a plant

Question 10

Transpiration > Upward movement of a plant

Answer 10

As the water evaporates from the leaf by transpiration more water is pulled upwards though the xylem into the leaf

Question 11

Role of transpiration

Answer 11

Water evaporates from leaf cells

This creates an osmotic gradient

The leaf cells become less turgid

Causing water to move out of the xylem to the leaf cells

Question 12

Minerals are

Answer 12

Absorbed into roots by diffusion and active transport

Question 13

Water passes from

Answer 13

Root hairs into root xylem

Question 14

Xylem

Answer 14

Transports water from the roots to all parts of the plant

Question 15

Calcium

Answer 15

Make cell walks

Question 16

Magnesium

Answer 16

Part of the chlorophyll

Question 17

Potassium

Answer 17

Absorbed by active transport which requires energy

Question 18

Nitrates and phosphates

Answer 18

Transported from the roots in the xylem, dissolved in water
