Archaeplastida

Synaphamorph of archaeplastida

Primary endosymbiosis to make original chloroplast

How arechaeplastid described

Unique life cycle : alternation of generations

If the ploidy changes preferably by half it is (2n To n )

Product of Meiosis

If ploidy Does not change it is

Product of mitosis

2nd step of alternation of generation archaeplastida life cycle

Meiosis occurs and sporophytes makes spores

First step of alternation of generation archaeplastida life cycle

Start with two and structure called sporophytes

Describe sporophytes

Multicellular and produces spores

What are spores

Haploid 1 N

3 step of alternation of generation archaeplastida life cycle

Mitosis occurs and spores grow in the Gametophyte

Describe gametophyte

Multicellular and haploid

4 step of alternation of generation archaeplastida life cycle

Gametophyte produces gametes (sperm and egg (1n))through mitosis

5 step of alternation of generation archaeplastida life cycle

Fertilization occurs the sperm, fertilizers the egg, and produces a new zygote (2N)

6 step of alternation of generation archaeplastida life cycle

Zygote (2n), through mitosis, develops into sporophyte

Process where sporophyte produces spores

Meiosis

Process where spores grow into gametophyte

Mitosis

Sporophyte and gametophyte are

Multicellular

archaeplastics/plants are unique compared to animals because

They have two different multicellular stages one that is 2n sporophyte

Other is 1n gametophyte
