Plants Flashcards
(46 cards)
The root
Anchors the plant, absorbs water and minerals from the soil, and stores food made in the leaves
The stem
Supports the leaves and flowers and allows for the transport of materials up and down the plant.
The leaf
Makes food, loses water vapour, and exchanges the gases carbon dioxide and oxygen with the air.
The flower is for
Reproduction, it firms the seeds.
Plants are identified
By their flowers and leaves
Photosynthesis
Is the process by which green plants make food
Chlorophyll
Is the green chemical needed for photosynthesis
Chloroplasts
Chlorophyll is found in the chloroplasts of plant cells.
Photosynthesis is carried out
In all the green (chlorophyll containing) parts of the plant- especially the leaves
Chlorophyll traps lights energy
And uses it to combine carbon dioxide and water, to form glucose and oxygen
Phloem
Glucose travels around the plant in special cells called phloem
Stomata
Tiny pores on leaves surface are called stomata
Word equation for photosynthesis
Light
Carbon dioxide+water —> Glucose+oxygen
Chlorophyll
Water is absorbed
Through the roots of a pant
Xylem vessels
Water and minerals move up through the plant in th xylem vessels
Transpiration
Is the loss of water vapour from the leaves of a plant
Transpiration stream
The flow of water through a plant is called the transpiration steam
Phloem
Food is transported from the leaves to the rest of the plant in the phloem
Tropism
Is the growth of a plant in response to a stimulus
Phototropism
Is a pants growth response to light. Plant stems grow towards the light, allowing their leaves to get light
Geotropism
Is a plants growth response to gravity. Plant roots grow towards the source of gravity, allowing them to get water.
Plants reproduce sexually
By means of flowers
Petals are coloured and scented
To attract insects
The sepal
Protects the flowers before it blooms
