Pollen of a flower needs to reach the petals for fertilisation. yes or no
Answers
Answer:
Pollination is a very important part of the life cycle of a flowering plant. It is part of the sexual reproduction process of flowering plants, which results in seeds that will grow into new plants. Flowers are the structures of flowering plants that contain all the specialised parts needed for sexual reproduction.
Plants have gametes, which contain half the normal number of chromosomes for that plant species. Male gametes are found inside tiny pollen grains on the anthers of flowers. Female gametes are found in the ovules of a flower. Pollination is the process that brings these male and female gametes together.
Pollen can’t get from the anthers to the ovules on its own, so pollination relies on other things to move the pollen. The wind or animals, especially insects and birds, pick up pollen from the male anthers and carry it to the female stigma. Flowers have different shapes, colours and smells, and often sugary nectar and nutritious pollen, to encourage animals to visit and pollinate them. Wind-pollinated flowers are shaped to make it easy for the wind to pick up or deposit pollen.
Many flowers can be pollinated by their own pollen – a process called self-pollination. However, this does not always result in the genetic variation needed for species to survive. Many plants have ways to make sure they are only pollinated by pollen from a flower on a different plant, which is called cross-pollination. Some have the male and female parts in separate flowers on the same plant, while others have male and female flowers on different plants. Many have the stigmas and anthers ripening at different times to prevent self-pollination.

Answer:
FALSE
The pollen grains need to reach the ovule for the fertilization.
