And uses it to combine carbon dioxide and water, to form glucose and oxygen

Question 11

Phloem

Answer 11

Glucose travels around the plant in special cells called phloem

Question 12

Stomata

Answer 12

Tiny pores on leaves surface are called stomata

Answer 14

Through the roots of a pant

Question 15

Xylem vessels

Answer 15

Water and minerals move up through the plant in th xylem vessels

Question 16

Transpiration

Answer 16

Is the loss of water vapour from the leaves of a plant

Question 17

Transpiration stream

Answer 17

The flow of water through a plant is called the transpiration steam

Question 18

Phloem

Answer 18

Food is transported from the leaves to the rest of the plant in the phloem

Question 19

Tropism

Answer 19

Is the growth of a plant in response to a stimulus

Question 20

Phototropism

Answer 20

Is a pants growth response to light. Plant stems grow towards the light, allowing their leaves to get light

Question 21

Geotropism

Answer 21

Is a plants growth response to gravity. Plant roots grow towards the source of gravity, allowing them to get water.

Pollen

Answer 27

Is made in the anther of the stamen

Question 28

The egg

Answer 28

Is made in the ovary of the carpel

Reproduction involves 5 stages

Answer 29

1. pollination
2. fertilisation
3. seed and fruit formation
4. seed dispersal
5. germination

Question 30

Pollination

Answer 30

Is the transfer of pollen from another to stigma

Question 31

Plants are pollinated by either

Answer 31

Insects or wind

Question 32

Fertilisation

Answer 32

Is the fusion of the pollen nucleus with the egg nucleus to form a zygote
