In angiosperms, after pollination, pollen grains land on the stigma of a flower, where they germinate and form a pollen tube that travels down the style to the ovary. During this process, sperm cells from the pollen tube fertilize the ovule, leading to the formation of a zygote. The zygote develops into an embryo, while surrounding tissues form the seed coat and endosperm, which provides nourishment. Once maturation is complete, the seed is formed, ready for dispersal and eventual germination.

What conducts the most pollination for angiosperms?
Bees are the most common pollinators for angiosperms. They are attracted to flowers by their colors and scents, and as they collect nectar and pollen, they inadvertently transfer pollen between flowers, facilitating the process of pollination.
What is the difference between pollination and fertilization gymnosperms vs angiosperms?
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.
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 angiosperm adaptation increases the efficiency of pollination?
The evolution of flowers, which contain reproductive structures such as stamens and pistils, increases the efficiency of pollination in angiosperms. Flowers help attract pollinators like insects and birds, ensuring that pollen is transferred between different individuals, leading to successful fertilization and seed production.
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 happens between pollination and fertilisation?
After pollination, the pollen grain germinates and forms a pollen tube that grows down the style of the pistil to reach the ovule. Fertilisation occurs when the sperm cell from the pollen grain fuses with the egg cell in the ovule, resulting in the formation of a zygote.

Distinguish between self-pollination cross-pollination?
The process of pollination from same flower is called self-pollination. the process of pollination from another flower of same breed is called cross-pollination.
What is Different between self pollination and cross pollination?
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
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 pollination is reproductive advance found in angiosperm plants and this type of pollination is aided by large colorful flowers?
The type of pollination associated with reproductive advances in angiosperm plants that is aided by large colorful flowers is known as animal pollination, specifically entomophily, which involves insects such as bees and butterflies. These flowers attract pollinators with their vibrant colors and sweet scents, facilitating the transfer of pollen from one flower to another, which enhances genetic diversity and increases reproductive success. This relationship between flowering plants and their pollinators is crucial for the reproduction of many angiosperms and contributes to ecosystem biodiversity.
Is cross pollination between different types of flowers possible?
No, only cross pollination between plants of the same genus and species
Why is self pollination better than cross pollination?
Cross pollination results in hybrid seed formation. Hybrids in general are vigorous than self pollinated plants due to additive gene action.
