2. Mitosis

3. Differentiation

4. Both (2) and (3)

Green algae do not store food in the form of

1. Protein

2. Starch

In organisms with haplontic life cycle: 

(1) The zygote divides by meiosis to form haploid spores that grow into haploid individuals. 

(2) The zygote divides by mitosis to produce diploid spores that grow into diploid individuals.

(3) The zygote divides by meiosis to produce haploid gametes that develop into haploid individuals.

(4) The zygote divides by meiosis to produce diploid gametes that develop into diploid individuals.
