EVERYDAY SCIENCE

Detailed explanation-1: -By contrast, in seed plants (gymnosperms and angiosperms), this dependency on water is highly restricted because pollen, the highly reduced male gametophyte generation, is the agent of male gamete dispersal and is more resistant to desiccation than sperm (Pacini, 2000).

Detailed explanation-2: -Angiosperms live in all terrestrial and aquatic habitats on earth.

Detailed explanation-3: -Marine angiosperms are underwater flowering plants that live in marine environments, and are commonly called seagrass. They look very similar to land grasses except they grow underwater. Even though they can be found in many waters, from the tropics to the Arctic, the majority are found in tropical coastal waters.

Detailed explanation-4: -No, angiosperms do not require water for fertilization. The pollen grains contact the stigma of the flower and travel down the style to the ovary where they fertilize the seeds. The pollen allows the sperms cells to travel, negating the need for water.
