There are 22 different amino acids found in nature. additional examples are shown below. with your group, write one or two grammatically correct sentences to describe how these amino acids are similar and how they are different. use the terms r-group, amine group, and carboxyl group in your description

            Each amino acid is composed of three main components.

1. Carboxylic group

2. amino group

3. Hydrogen atom

4. Alkyl or aryl group.

All these groups are attached to aplha carbon.

Similarities and differences:

                     In all amino acids, amino group, carboxylic group and hydrogen atom remain same, the difference lie in the variation of alky or aryl group.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
