Detailed explanation-1: -Certain plants have a swollen, underground plant stem called a “corm.” The purpose of this stem is to store nutrients, food that the plant will use at a future time. Nutrients stored in the corm during one growing season will help in the production of roots, leaves, and flowers for the next growing season.

Detailed explanation-2: -Corms are enlarged underground stems that store food for the plant during dormancy. It is spherical in shape with a flattened base and grows vertically below the ground. They are very similar to bulbs. Unlike bulbs, corms are solid and do not have scales or fleshy leaves.

Detailed explanation-3: -Corms are actually enlarged underground stems that store nutrients, surrounded by papery outer layers. After stems sprout from the corm, buds form on top of the stem. Corms at their center are solid tissue, whereas Bulbs are immature layers of leaves.

Detailed explanation-4: -A corm is similar to a true bulb in that it is an enlarged, underground stem with a basal plate. However, the primary storage tissue is the stem itself rather than the modified leaf tissue. It is vertically oriented and has a terminal bud on top and axillary buds along the stem.
