Question

Explain the function of each of the following.
(a) Coleorhiza
(b) umbilical cord
(c) Germ pores.

Answer 1

Coleorhiza and germ pores are present in plants. And umbilical cord present in humans.

Complete answer:
To answer this question, we have to know about coleorhiza, umbilical cord and germ pores. Coleorhiza isa sheath-like structure found in a monocotyledon plant seed that acts as a protective covering enclosing the radicle. Umbilia is a genus of sea snails, marine gastropod mollusks in the family Cypraeidae, and the cowries. A germ pore is a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination.
The function of coleorhiza, umbilical cord and germ pores are as follows:

The coleorhiza is a defensive sheath that encloses the radicle in a few specific plants that is invaded by the root in germination. It assists in defending the radicle.
The umbilical cord functions as a blood origin for the foetus and as a way of transporting nutrients, proteins, fats, as well as vitamins to the foetus. It also transports waste products and low oxygen blood far away from the foetus.
The germ pore is opening in the exine portion of the pollen grain where it lacks sporopollenin. The germ pore assists in the production of the pollen tube and the elimination of the male gametes during fertilization.

Note: Coleorhiza typically envelops the radicle, connecting the coleoptile to the primary root. The umbilical cord is a tube like structure which links a mother with her baby during pregnancy. It has three blood vessels: one vein that carries food and oxygen from the placenta to your baby and two arteries that carry waste from your baby back to the placenta. Germ pore plays an essential part in the fertilization of plants.
