Plants > keywords Flashcards
Function of roots
Absorbs water + minerals
Stores food e.g: carrots
Stem
Holds up leaves + flowers
Transports water and mineral from the roots to the leaves
Stores food e.g: patatoes
Leaves
Makes food
Allows carbon dioxide in
Allows oxygen to pass out into air
Flowers
Produce seeds so plants can reproduce
Bud
Growth point
New leaves or flowers will grow from a bud
Transpiration
Is the loss of water from a plant
Where does transpiration occur
Stomata
- allows water vapour to evaporate from the leaves into the air
Transpiration stream
Flow of water from the roots to the leave of the plant
Functions of transpiration
Brings water to the leaves for photosynthesis
Brings materials to the leaves
Mineral transportation
Minerals are dissolved in water in the soil
They are absorbed by root in the water and pass around the plant in the water
Nitrogen
Makes healthy leaves
Phosphorus
Causes healthy roots
Who is water carry water + minerals around plant
Xylem
How is food carried around plant
Phloem
Photosynthesis
The way in which green plants make their own food
Factors of photosynthesis
Carbon dioxide
Water
Light chlorophyll
Carbon dioxide (photosynthesis)
Passes from air into leaf through the stomata
Water (photosynthesis)
From soil passes through roots + moves up through the plant in the xylem
Light (photosynthesis)
From sun is absorbed by leaves
Chlorophyll (photosynthesis)
Green pigment found in leaves
Products of photosynthesis
Glucose
Oxygen
Glucose (photosynthesis)
- food made by plant
- stored as starch
Oxygen (photosynthesis)
Used for:
- respiration
- release out into air
Word equation for photosynthesis
Carbon dioxide. Sunlight Glucose
+. –>. +
Water. Chlorophyll Oxygen
Tropism
Growth of a plant in respond to a stimulus
Phototropism
Growth in a plant due to light (plants grow towards light)
Geotropism
Growth of a plant in response to gravity (roots grow down into soil)
