Flashcards in Structure And Transport In Flowering Plants Deck (15):
1

Stem

Hold up the leaves and flowers.
Transport water and minerals from the roots to the leaves.
Transport food from the leaves to the roots.
Store food, eg. Potato

2

Leaves

Make food (photosynthesis)
Allows carbon dioxide in
Allows oxygen out into the air
Allows water vapour to pass out
Some store food, eg. Cabbage, lettuce

3

Flowers

Produce seeds so the plant can reproduce

4

Bud

Growth point
New leaves or flowers will grow from a bud

5

Transpiration

The loss of water from a plant

6

Stomata

Small holes on the underside of the leaf
They allow water vapour to evaporate from the leaves into the air
Where transpiration occurs

7

Transpiration stream

The flow of water from the roots to the leaves of the plant.

8

To show the path of water through a plant

Celery experiment

9

To show that water is taken in by the roots and passes up and out of a plant

Test tube with a plant in it.
The plant is in water with oil on top so the water can't evaporate. (This then proves the roots absorb water)
Mark the level of the water with a marker.

10

Roots

Anchor and support the plant.
Absorb water and minerals.
Store food, eg. Carrot

11

To show that water evaporates from the surface of a leaf by transpiration

Plastic bag is TIED AROUND THE STEM of a potted plant.
Anhydrous Copper Sulphate is used to test if water is present.
If water is present it will turn blue

12

Functions of transpiration

Brings water to the leaves for photosynthesis
Brings minerals to the leave (dissolved in the water)
Cool the plant

13

Mineral transport

Minerals are dissolved in water in the soil
Minerals are absorbed by the roots in the water and pass around the plant in the water
Nitrogen - healthy leaves
Phosphorous - healthy roots
Potassium - healthy flowers and fruit

14

Xylem

Carries water and minerals around the plant

15

Phloem

Carries food around the plant
