What is the difference between pollination and fertilization gymnosperms vs angiosperms?

angiosperm fertilization involves the so called "double fertilization" which is absent in gymnosperms. In angiosperms the secondary nucleus (formed from fusion of two polar cell nuclei) gets fertilized by the second male gamete along with fertilization of the egg cell of the embryo sac. The fertilization of the egg cell results in the formation of zygote whereas the fertilization of the secondary nucleus results in the formation of PEN (primary endosperm nucleus).PEN develops into endosperm while zygote into embryo. Perisperm provides the necessary nourishment to the developing embryo.

In gymnosperms, pollination refers to the transfer of pollen to the female ovule, while fertilization is the fusion of the male gamete with the female gamete within the ovule. In angiosperms, pollination occurs when pollen reaches the stigma of the flower, and fertilization happens when the male gamete fuses with the female gamete in the ovule, which is enclosed in the ovary.

How is the alternation of generations the same and how is it different between angiosperms and gymnosperms?
Alternation of generations is the same in all plants in the sense that during sexual reproduction gametophytic generation alters with the sporophytic generation. In angiosperms and gymnosperms the only difference is the presence of embryo sac in the ovule in place of archegonium in gymnosperms. Also double fertilization takes place in angiosperms to have sporophytic endosperm, which remains gametophytic in gymnosperms.
What is the difference between pollination and fertilization in angiosperm?
Pollination is the transfer of pollen from the anther to the stigma, while fertilization is the fusion of the male gamete with the female gamete to form a zygote. In angiosperms, pollination leads to the transfer of pollen to the stigma, followed by fertilization of the egg cell within the ovule to produce a seed.
What is the difference between pollination and fretilization?
Pollination is a proces of dispersing pollen grains to stigma and the fertilization is the followed proces of pollination.
What is the main difference between an angiosperm and a non-angiosperm?
Angiosperms are flowering plants that produce seeds enclosed within a fruit, while non-angiosperms, like gymnosperms and ferns, do not produce flowers or fruits. Angiosperms have specialized reproductive structures that aid in pollination and seed dispersal, whereas non-angiosperms rely on other methods for reproduction.
What is the difference between gyptogamae and phanerogamae?
Gymnosperms do not form flowers and have naked seeds, while angiosperms have flowers and seeds enclosed within a fruit. Gymnosperms include conifers, cycads, and ginkgo, while angiosperms are further divided into monocots and dicots. Gymnosperms are typically wind-pollinated, while angiosperms are often animal-pollinated.
In what ways does pollination in gymnosperms differ from pollination in angiosperms?
One main difference is that gymnosperms typically rely on wind for pollination, while angiosperms often rely on animals like bees for pollination. Additionally, gymnosperms have exposed seeds, while angiosperms have seeds enclosed within a fruit. Finally, gymnosperms do not produce flowers, while angiosperms do.
How are gynosperms different from angia sperms?
The difference between gymnosperms and angiosperms is that gymnosperms develop cones as their seed to use in the fertilization process, and angiosperms produce flowers and fruits as their seed to use in the fertilization process.

What is the main difference between agiosperms and gymnosperms?
In angiosperm seeds are enclosed inside the ovary whereas in gymnosperm seeds are naked (i. e. born on megasporophyll) Gymnosperms have archegonium for egg whereas in angiosperms it is replaced by an embryo sac.
What is the difference between pollination and fertilization in angiosperm?
Pollination is the transfer of pollen from the anther to the stigma, while fertilization is the fusion of the male gamete with the female gamete to form a zygote. In angiosperms, pollination leads to the transfer of pollen to the stigma, followed by fertilization of the egg cell within the ovule to produce a seed.

Compare and contrast life cycles of angiosperms and gymnosperms?

What is the difference between pollonation and fertilization?
Pollination is the transfer of pollen from the male reproductive organ to the female reproductive organ of plants, while fertilization is the fusion of the male and female gametes to form a zygote. Pollination is necessary for fertilization to occur in flowering plants, as it brings the male gametes (pollen) to the female gametes (ovule).

What are the differences between angiosperm and gymnosperm reproduction?
While they both produce seeds, gymnosperms and angiosperms differ with respect to the location of seed development, and their flowering.Gymnosperms; naked seeds. Referring to the unenclosed condition of the seeds, as when they are produced they are found naked on the scales of a cone.Angiosperms; flowering plants. Referring to the use of flowers, which contains a carpel as the basic unit of the female reproductive organ.Refer to the related links:
