Plant Flashcards
Flowering plants
Consist of a shoot and a root
Shoot
Consists of the stem ,leaves,buds and flowers
The root
Anchors the plant,absorbs water and minerals from the soil,and stores food made in 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 forms the seeds
Plants are identified
By their flowers and leaves
Photosynthesis
Is the process by which green plants make food
It is carried out I. All the green (chlorophyll-containing)parts of the plant
Chlorophyll
Is the green chemical needed for photosynthesis
It is found in chloroplasts of plant cells
Chlorophyll traps lights energy and uses it to combine carbon dioxide and water to form glucose oxygen
Glucose
Trave,s around the plant in special cells called phloem
Leaves are specially designed for photosynthesis
They are flat and thin,have air spaces between the cells and tiny pores on their surface called stomata
Carbon dioxide,water,light and chlorophyll
Are needed for photosynthesis to occur
Carbon dioxide enters the leaf from the air,water is absorbed from the soil
Through the roots
Boiling
To kill cells and soften leaf
Methylated
To remove chlorophyll from the leaf
Rinsed
To soften it
Iodine
To test the lead for the presence of starch
Xylem vessels
Where water and Veessels move up through the plant
Transpiration
Is the loss of water vapour from leaves of a plant
Stomata
When the water leaves the plant through this of the leaf
Little holes underneath the leaf
Transpiration stream
The flow of water through a plant
Transpiration provides
Water for photosynthesis ,carries minerals in the water ,and cools the plant
Phloem
Where food is transported from the leaves to the rest of the plant
A tropism
Is the growth of a plant in response to a stimulus
