All cells contain dna, which provides information for the cells to make a. new types of genes. b. new types of organisms. c. different kinds of dna. d. different kinds of proteins.

The life cycle of plant shows alternation of generation that is their life is divided into sporophytic (2n) and gametophytic stage (n).

Sporophyte dominates the life cycle and is diploid while gametophyte is reduced which is haploid.

Sporophytic (diploid) forms include:

1. Zygote

2. Embryo

3. Seed

4. leaves

5. Stem

6. Root

7.Fruit

8. Flower and its parts

Gametophyte (haploid) forms include:

1. Megaspore or embryo sac that represents female gametophyte and includes egg cell, antipodal cells and secondary nucleus.

2. Microspore or pollen grains represents male gametophyte and includes haploid sperm cell that fuses with the egg cell and form zygote.
