Flashcards in Structure And Transport In Flowering Plants Deck (15):
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
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
Produce seeds so the plant can reproduce
New leaves or flowers will grow from a bud
The loss of water from a plant
Small holes on the underside of the leaf
They allow water vapour to evaporate from the leaves into the air
Where transpiration occurs
The flow of water from the roots to the leaves of the plant.
To show the path of water through a plant
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.
Anchor and support the plant.
Absorb water and minerals.
Store food, eg. Carrot
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
Functions of transpiration
Brings water to the leaves for photosynthesis
Brings minerals to the leave (dissolved in the water)
Cool the plant
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
Carries water and minerals around the plant
