Question

4 Define the following terms.
a. Callus
b. Pollination
c. Sporogenesis
d. Vegetative propagation
e. Hybridization

Answer 1

Answer:

a). Thickened layers of skin, often on the hands or feet, where friction repeatedly occurs.

b).Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

c).the process of spore formation.

d).A method of plant propagation not through pollination or via seeds or spores but by way of separating new plant individuals that emerge from vegetative parts, such as specialized stems, leaves and roots and allow them to take root and grow.

e).Hybridization occurs when an atom bonds using electrons from both the s and p orbitals, creating an imbalance in the energy levels of the electrons. To equalize these energy levels, the s and p orbitals involved are combined to create hybrid orbitals.
