Question

What novel innovations did the evolution of the seed plant life cycle involve compared with other groups of land plants? Select all that apply.O dispersal of multicellular gametophytes O dispersal through air O an ecologically dominant sporophyte generation O fertilization in the absence of environmental water O dispersal of multicellular sporophytes

Answer 1

Fertilization in the absence of environmental water

Step-by-step explanation:

• About 360 million years ago, seeds appeared on Earth.

• The seed bearing plant is divided into two categories:

• Gymnosperms (naked seeds)

• Angiosperms (seeds enclosed in ovary)

• Seed bearing plant produce Microspores which leads to the formation of pollen grains. The pollen grain serve as a carrier for the sperm to the egg.
• Seed bearing plant produce Megaspores, which formed within the ovules, and results into the formation of seed, when sperm fertilizes with the egg.
