Detailed explanation-1: -Photosynthesis primarily happens in green leaves (not colorful autumn leaves). Leaves are ideal for photosynthesis because they are usually broad and flat, giving plenty of surface area for light to be absorbed. They are also thin, which means diffusion of gases such as carbon dioxide can happen quickly.

Detailed explanation-2: -No, all plants are not autotrophic. Some of the non-green plants such as dodder plants obtain their food from other plants and these plants are heterotrophic plants. Heterophic plants generally do not possess chlorophyll, which inhibits their ability to prepare their own food.

Detailed explanation-3: -All plants need space to grow, the right temperature, light, water, air, nutrients, and time.

Detailed explanation-4: -The leaves which are partly green and partly white are called ‘variegated leaves’. The plants such as croton and coleus have variegated leaves which are partly green and partly white. Was this answer helpful?
