OBJECTIVE FORESTRY

Detailed explanation-1: -In phototropism a plant bends or grows directionally in response to light. Shoots usually move towards the light; roots usually move away from it.

Detailed explanation-2: -Plants use light to track time, which is known as photoperiodism. They can tell the time of day and time of year by sensing and using various wavelengths of sunlight. Light can also elicit a directional response in plants that allows them to grow toward, or even away from, light; this is known as phototropism.

Detailed explanation-3: -Phototropism is the directional response of a plant that allows the plant to grow towards or in some cases away from the light. Process of phototropism: Leaf tips and stem tips have a hormone called auxin which is sensitive to light. It allows the plant to positively grow towards the light source.

Detailed explanation-4: -Phototropism is defined as the orientation of the plant or other photosynthesizing organisms in response to light. Phototropism is a phenomenon by which a plant can maximize its exposure to sunlight because plants need sunlight to make food.
