Question

give appropriate biological terms of the following
i)protective sheath of radical of a maize grain
ii) cotyledon of a maize grain
iii) germination seen in rhizobium ap
iv) A mature ovary in plant​

Answer 1

Answer:

1 The radicle is the first root of the plant and grows downward in the soil. Corn seed coleoptile: a pointed protective sheath covering the emerging shoot (epicotyl) that pushes above the ground for the first leaves to appear.

2The embryo in maize grain consists of a single cotyledon called scutellum, a radicle and a plumule. ... The plumule is located towards the upper side of the embryonic region opposite to radicle. It is also enclosed in a protective sheath known as coleoptile.

3 Seeds dressed with Rhizobium and plant grown in soil inoculated with Rhizobium showed high seed germination and stimulatory growth over the control. These results summarized that Rhizobium can be effectively used as a bioinoculant or biofertilizer to enhance the yield of crops.

4 Ovary contains ovules that develop into seeds eventually after fertilization. After the process of fertilization, the zygote, in time, differentiates to form an embryo inside the ovule. The ovary matures to turn into the fruit which can either be fleshy or dry, in which the seeds are embedded.
