Plants Flashcards
Flower
Reproduction
Leaf
Photosynthesis and transpiration . Leaves breathe carbon dioxide and breathe out oxygen(gas exchange) . Food storage .
Transpiration
Cools the plant when water vapour passes through it .
Stomata are like the pores of leaves .
Photosynthesis
Makes food for the plant
Gas exchange
Allows the exchange of carbon dioxide and oxygen
Stem
The stem allows transport of food , water and minerals around the plant .
Also supports the plant and holds it upright .
Stems store food e.g potato
Gas exchange in lenticles
Fruit
Protects seeds
Provides food for seeds
Bud
Allows new leaves and flowers to grow . Apical bud at top , lateral buds on the side .
Roots
Anchor and support
Take in water and nutrients
Store food e.g carrots and turnips
Water
Is absorbed up through the roots , and travels to the leaves and the tips of the plant though the XYLEM
Xylem
Water and dissolved solids e.g minerals
Phloem
Food from leaves around the plant
F&F
Photosynthesis
Is the process where green plants make food using light energy
Chlorophyll
Is the green chemical needed for photosynthesis, it is found in the chloroplast of plant cells
Carbon dioxide
Enters the stomata (holes on underside of leaf)
Photosynthesis word equation
carbon dioxide + water –> glucose + oxygen
How are leaves designed for photosynthesis
Leaves are flat and thin so sunlight can get through them
Leaves have tiny holes called STOMATA to allow oxygen out and carbon dioxide in .
What do leaves need for photosynthesis
Carbon dioxide comes from the atmosphere
Water comes in through the from the soil
Chlorophyll in their chloroplasts
Sunlight
What do the plants do with the glucose when they make it
Like us , plants use glucose for growing and repairing damaged parts
If they don’t use it they store it as starch this is why we can eat plants that store starch such as potatoes and wheat .
