How Light Affects Plant Growth?
A plant needs water, nutrients, light and warmth to grow. If the plant doesn't have these things it will die.
If a plant has light and a little bit of warmth it will grow like a normal plant would. When the plant is green it means the sun has been shining on it causing it to make chlorophyll. All plants have water and light will stay healthy and grow bigger and bigger.
Plants that don't have any light will go pale and the leaves will start to go brown and die. The roots won't be able to suck up any nutrients or water to the plant. With no light the plant will droop because it has no energy to stay up straight. The root will flop over and the plant won't have any support holding it up.
Some plants can grow in the dark. To test to see if plants can grow in the dark. The plants will need the same amount of water so then it is a fair test. After a while the plant will go pale because it hasn't had any light to photosynthesis. Plants can survive for a little bit because the production that harmones is stimulated by the dark which makes suppressed light.
Finally the rest of the plant will start to fade out because of no sunlight, chlorophyll or nutrients. The colour will be an orangey brownish. All the other parts will have no strength and start to rot.
Plants grow every where and many different places. They grow in all conditions like hot weather or cold. No plants can grow without light.
