Features Pea seed Corn seed Is there any covering of the seed? Pea seeds remain covered in a pod. Corn seeds do not have any outer covering. Is there any plantlet in the seed? Pea seed contains a plantlet in the seed. Corn seed contains a plantlet in the seed. Is there any food for sapling in the seed? Pea seed is a dicotyledonous seed. The food remains stored in the cotyledons. Corn seed is a monocotyledonous seed. The food remains in the single cotyledon. What are the parts of the sapling? The sapling consists of radicle and plumule. The sapling consists of radicle and plumule.

Are the two seeds completely identical or there are some dissimilarities? Fill the following table. Features Pea seed Corn seed What are the different layers of seed coat? What are the other parts apart from the small seedling present within seed coat? What is the function of this zone? Name the part covering the root of the seedling. Name the covering of stem of the seedling. How many cotyledons are attached with the seedling? Where does the plantlet store its food?

Seed is a ripened ovule that contains an embryo or miniature plant, adequate reserve food in the cotyledons for the development of the embryo. Features Pea seed Corn seed What are the different layers of seed coat? Testa and tegmen Testa and tegmen What are the other parts apart from the small seedling present within the seed coat? Cotyledons, endosperm Cotyledons, endosperm What is the function of this zone? Cotyledons provide nourishment to the young seedling and develop into the first leaf of the plant. The embryo and the radicle and plumule of the embryo respectively develop into root and shoot of the plant. Endosperm provide nourishment to the developing embryo. Cotyledons provide nourishment to the young seedling and develop into the first leaf of the plant. The embryo and the radicle and plumule of the embryo respectively develop into root and shoot of the plant. Endosperm provide nourishment to the developing embryo. Name the part covering the root of the seedling. Coleorhiza Coleorhiza Name the covering of the stem of the seedling. Coleoptile Coleoptile How many cotyledons are attached with the seedling? Two One Where does the plantlet store its food? Endosperm Endosperm As a whole, it can be said that pea seed is a dicotyledonous seed and corn seed is a monocotyledonous seed. Both seeds have similar internal parts. The structure, shape, and size of seeds are different.
