What is pollini a?
Pollinia are clusters of pollen grains that are often found in certain flowering plants, particularly orchids. These structures facilitate the transfer of pollen during pollination, helping ensure fertilization. When an insect visits a flower, it may inadvertently pick up pollinia and carry them to another flower, thereby aiding in the plant's reproductive process. Pollinia can be quite sticky, allowing them to adhere to the pollinator more effectively.
What way does pollination differ between non-flowering seed plants and flowering plants?
Flowering plants require pollinatio non-flowering plants do not.
Pollination occurs on the?
flower of flowering plants
What are the characteristics of flowering and non flowering plants?
it is about the plants that always flowers
Describe pollination and why it is important for flowering plants?
it leads to the creation of new seeds that grow into two plants
How does pollination occur in non-flowering plants?
Nonflowering plants depend on wind and water to scatter their spores or seeds.
The evolution of flowering plants and insects that transport their male gametes is an example of what?
This is an example of coevolution, where two or more species reciprocally affect each other's evolution. In this case, the flowering plants and insects have evolved traits that benefit each other, such as the plants producing nectar for the insects in exchange for pollination services.
What is the difference between pollination and fertilisation in flowering plants?
their is a lot of difference. they are the steps of asexual reproduction.
Why pollination happens?
Pollination is required for flowering plants to reproduce. This is due to the pollen acting as the sperm for the plant, and the pollen has to enter the ovum of the plant to create the seeds.
Why does spraying insecticides have a adverse effect on flowering plants?
Insects are needed to pollinate many plants. Without pollination, fruit and seeds are not produced.
Is pollination in animals a form of asexual reproduction?
Pollination only occurs in flowering plants. It is part of the process of sexual reproduction. The pollen grain contains the male gamete.
What kind of spores are produced by flowering plants?
Flowering plants produce pollen grains, which are equivalent to spores in non-flowering plants. These pollen grains are responsible for plant reproduction through the process of pollination, where they are transferred to the female reproductive organs of the flower for fertilization.
