A. Two different forms a plant can have
Explanation:
Higher plants, lower plants (mosses) and ferns undergo a life cycle called ALTERNATION OF GENERATIONS. In this life cycle, they switch between a haplontic and diplontic forms of life.
The haplontic (haploid) life form which produces haploid (n) gametes is called GAMETOPHYTE while the diplontic (diploid) life form which produces the spores that germinates is called SPOROPHYTE. Hence, sporophyte and gametophyte are two different forms a plant can have.

<h3>What caused Pangea to split into the current plates?</h3>
- Similar to how it was formed, Pangea started to fragment around 200 million years ago due to tectonic plate movement brought on by mantle convection.
- The supercontinent split as a result of new material moving away from rift zones, just as new material helped construct Pangea.
