What are the reproductive structures of genosperms?
Most Gymnosperms are diecious with the male and female reproductive organs on different plants. The male "flower" produces pollen and the female "flower" contains the ovary. Many female gymnosperms produce cones that house the fertilized eggs until the seeds are mature.
What are male gametophytes called?
Male gametophytes of seed-producing plants are called pollen grains. These are the structures that produce the male gametes, known as sperm cells, which are required for fertilization to occur. Pollen grains are dispersed through the air or by insects to reach the female reproductive structures of plants.
What are haploid spores on the underside of ferns fronds that are found in clusters called Sori?
The haploid spores found in clusters called sori are reproductive structures on the underside of fern fronds. These spores are released to disperse and ultimately germinate into new gametophytes, leading to the development of new fern plants.
Are fronds the ferns sexual reproductive structure?
No, fronds are not the sexual reproductive structure of ferns. Fronds are the leafy structures of ferns that help in photosynthesis and reproduction occurs through specialized structures called spores produced on the underside of the fronds in structures called sori.
What contains the plant sperm?
The plant sperm is contained within the pollen grains produced by the anther of a flower. Pollen grains are the male gametophytes of plants and contain the male reproductive cells that will fertilize the female ovule.
What is spore of gymnosperm?
The spores of gymnosperms are reproductive structures produced in the sporophyte generation. These spores are released from specialized structures called sporangia and develop into male and female gametophytes that produce eggs and sperm for fertilization. Gymnosperms include plants like conifers, cycads, and ginkgoes.
What are the reproductive structures of genosperms?
Most Gymnosperms are diecious with the male and female reproductive organs on different plants. The male "flower" produces pollen and the female "flower" contains the ovary. Many female gymnosperms produce cones that house the fertilized eggs until the seeds are mature.
What is the seed bearing structure if gymnosperm called?
The seed bearing structure of gymnosperms is called a cone or a strobilus. It contains the reproductive structures where seeds develop and mature. Gymnosperms do not produce flowers or fruit like angiosperms.
What are the spore bearing structures and club mosses and horse tails in the cones of Gymnosperms called?
The spore bearing structures in club mosses and horsetails and the cones of gymnosperms called strobili.
What are the reproductive structures of a fern?
Ferns reproduce through spores produced in structures called sporangia. Sporangia are typically found on the underside of the fronds or in clusters called sori. When the spores are released and germinate, they grow into small heart-shaped structures called gametophytes, which produce eggs and sperm for sexual reproduction.
What are the spores bearing structures in the club mosses and horsetails and the cones of gymnosperms called?
The spore bearing structures in club mosses and horsetails and the cones of gymnosperms called strobili.
What type of spores do selanginella produces?
Selaginella plants produce spores called microspores and megaspores. Microspores give rise to male gametophytes, while megaspores develop into female gametophytes. These spores are produced in sporangia located on the underside of their reproductive structures called strobili.
Which groups have flowers Bryophytes Ferns Gymnosperms Angiosperms?
Among the groups listed, only Angiosperms and Gymnosperms produce flowers. Angiosperms, commonly known as flowering plants, produce flowers as part of their reproductive process, while Gymnosperms, such as conifers, have reproductive structures called cones but do not produce true flowers. Bryophytes, like mosses, and ferns do not produce flowers; instead, they reproduce through spores.
What are male gametophytes called?
Male gametophytes of seed-producing plants are called pollen grains. These are the structures that produce the male gametes, known as sperm cells, which are required for fertilization to occur. Pollen grains are dispersed through the air or by insects to reach the female reproductive structures of plants.
What are plants called don't have seeds enclosed in a vessel?
Plants that do not have seeds enclosed in a vessel are called gymnosperms. This group includes conifers, cycads, ginkgoes, and gnetophytes, which produce seeds that are often exposed on cones or other structures. Unlike angiosperms, which have seeds enclosed within fruits, gymnosperms typically have a more primitive reproductive system.
What is the male reproductive structures of a pea plant?
The male reproductive structures of a pea plant are called the stamen
Where are the spores in gymnosperms found?
In gymnosperms, spores are found in specialized structures called cones or strobili. Male cones produce microspores that develop into pollen grains, while female cones contain megaspores that develop into ovules. These ovules eventually mature into seeds after fertilization, completing the reproductive cycle.
