Which group of plants require water for sexual reproduction?

Which group of plants require water for sexual reproduction?

The bryophytes, which include liverworts, hornworts and mosses, reproduce both sexually and vegetatively. The gametophyte is the most commonly known phase of the plant. All are small plants found growing in moist locations and like ferns, have motile sperm with flagella and need water to facilitate sexual reproduction.

Which of the following types of plants require water for reproduction?

water is required for fertilization in ferns; not in gymnosperms & angiosperms. ferns are seedless plants; gymnosperms & angiosperms have seeds. Only angiosperms have fruits.

Do angiosperms need water for reproduction?

Both sperm cells are required for successful fertilization in angiosperms. Pollen allows angiosperms and gymnosperms to reproduce away from water, unlike mosses and ferns which require water for sperm to swim to the female gametophyte.

Do bryophytes require water for fertilization?

Bryophytes also need a moist environment to reproduce. Their flagellated sperm must swim through water to reach the egg. The sporophytes of bryophytes do not have a free-living existence. They grow directly out of the fertilized egg in the archegonia, and remain dependent on the parent gametophyte for their nutrition.

In which plant type is water not required for fertilization?


Does gymnosperms have ovary?

Because gymnosperms have no ovary, they can never produce fruit. Seeds develop from the ovules that are found in the developed ovaries or fruit, but in the case of gymnosperms, the ovules are located directly on the surface of the flower or cone.

What characteristics do all angiosperms have in common?


  • All angiosperms have flowers at some stage in their life.
  • Angiosperms have small pollen grains that spread genetic information from flower to flower.
  • All angiosperms have stamens.
  • Angiosperms have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly.

What is the differences between gymnosperm and angiosperm?

The key difference between angiosperms and gymnosperms is how their seeds are developed. The seeds of angiosperms develop in the ovaries of flowers and are surrounded by a protective fruit. Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers.

What are the main differences between eudicots and monocots?

Eudicots produce tricolpate pollens with three pores while monocots produce monosulcate pollens with a single pore. So, this is the key difference between eudicots and monocots. Moreover, eudicots produce two cotyledons in their seedlings while monocots produce one cotyledon in their seedlings.
