Plant Flashcards
Flowering plants
Consist of a shoot and a root
The 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 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 in 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
Is carried out in all the green (chlorophyll containing) parts of the plant-especially the leaves
Chlorophyll
Is the green chemical needed for photosynthesis
Chlorophyll traps lights energy and uses it to combine carbon dioxide and water,to form glucose and oxygen
Glucose
Travels 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
.
Leaf in boiling water for one minute
To kill cells and soften leaf
Leaf in hot methylated sprint or alcohol
To remove chlorophyll from the leaf
Leaf rinsed in hot water
To soften it
Leaf placed on white tile and iodine added
To test the leaf for the presence of starch-If starch is present,leaf turns black.
Xylem vessels
Water and minerals move up through the plant
Transpiration
is the loses of water vapour from the leaves of a plant
Stomata
Water leaves the plant through the stomata of a leaf
Transpiration stream
The flow of water through a plant is called the transpiration stream
Transpiration provides
Water for photosynthesis,carries minerals in the water,and plant
Phloem
Food is transported form the leaves to the rest of the plant in the phloem
