NEET BIOLOGY

Detailed explanation-1: -The small pores present on leaves help plants take in carbon dioxide and give out oxygen during the process of photosynthesis. These pores are called stomata.

Detailed explanation-2: -Corn is a photosynthetic autotroph that uses the C4 photosynthetic pathway. Like most C4 plants, it has a particularly high rate of photosynthesis, has a high water use efficiency (carbon dioxide fixed compared to water loss) and will benefit less from rising carbon dioxide levels than C3 plants (Chapter 20).

Detailed explanation-3: -This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

Detailed explanation-4: -The husk surrounding the ear of corn/maize (Zea mays) has widely spaced veins with a number of interveinal mesophyll (M) cells and has been described as operating a partial C(3) photosynthetic pathway, in contrast to its leaves, which use the C(4) photosynthetic pathway.
