What parts of plants do photosynthesis?

Answer 1

the leaves of the plant contain the pigment chlorophyll, which allows the plant to take in energy from the sunlight. i also think the cells in the leaves are the ones that perfoms ATP to give the plant energy. but, technically even the roots are adapted for photosynthesis because that's the part that takes in water. Water plays a ver important role in photosynthesis.

Answer 2

Plant leaves have adapted in several ways to not just carry out but enhance photosynthesis in terms of Chemical composition, Shape, Numbers, Placement, Shedding etc. Let's take a brief look at each of these factors:

Composition

Virtually all plant leaves have Chlorophyll, which uses the energy from sunlight (electromagnetic radiation) to convert water (draw from the roots) and CO2 (from air) into starch and sugars.

Shape

Most plant leaves are flat shape and have a large surface area, which allows them to convert large amounts of water and CO2 into energy required for sustenance and growth

Numbers

Plants produce leaves in large numbers (relative to stem, branches and other parts). This, combined with their flat surface, improves the probability of a plant being able to conduct sufficient photosynthesis and thus be able to generate enough energy for survival

Placement

Plants leaves are designed to grow in minimally overlapping pattern such that each leaf has a higher likelihood of getting exposed to sunlight. Often plants won't even sprout in dense shade (or under other trees) and will actively change their shape to grow towards sunlight

Shedding

At higher latitudes (beyond tropics of Cancer or Capricorn), as winter begins setting in, sunlight available for photosynthesis gets severely reduced. Now, instead of being energy sources for a plant, the leaves only act as energy consumers and become a burden. So the leaves of deciduous plants are designed to fall off. Before they do, they produce the beautiful fall colors, which are a result of massive conversion from starch to sugar in the leaves, which causes the red/yellow/orange pigments in the leaves to become more prominent than green. The plants then go into low growth mode (like hibernation)

So you can see that plant leaves have adapted and optimized in several way to handle photosynthesis.

Answer 3

Mainly the green parts like leaves.They contain chlorophyll pigments.
