Detailed explanation-1: -Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. Photoperiodism is the regulation of physiology or development in response to day length.
Detailed explanation-2: -Light intensity is the amount of light received on the surface of the plant. 4. Flowers are provided with a constant food source when they are attached to a plant.
Detailed explanation-3: -Phototropism is a response to the stimulus of light, whereas geotropism (also called gravitropism) is a response to the stimulus of gravity . Plants responses to gravity: when the stem grows against the force of gravity, this is known as a negative geotropism.
Detailed explanation-4: -Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color.
