that is like asking, "Why can't I fertilize myself?" Think about it, we don't alone have the right combination of... um... well, sperm. Can a guy and another male have a child? No, why? because man alone doesn't have the right combination of sperm in his body, the same way for a female and another female... they can't have a baby. That is why there are men AND women.
Plants want to avoid inbreeding wherever possible. That way they tend to produce stronger offspring.
Well, for one thing, animals don't "pollinate."
Leaving that technical distinction aside... some species of animals are capable of self-reproduction.
yes
A self-pollinating plant contains both male and female reproductive structures.
Before dehiscence of anther lobes
A parasitic plant.
Cross pollination is where the pollen in one plant is used to pollinate those eggs that are available in a different plant. It fosters the vegetation process in Flora.
Plants have the ability to pollinate to without pedals. This is just because bees will pollinate as well as eat.
it has no independent locomotion - it cannot move by itself
Any plant can pollinate with any plant. Just so long as there's bees there. Bees accidentally get pollen from other plants on there feet and can ACCIDENTALLY cross-pollinate. So, yes, a pear CAN pollinate with a plum tree.
they smell like a corpse to attract insects, and the insects pollinate them.
Self-pollination of a plant is where a plant's pollen (from the anthers) lands on the same plant's stigma, causing it to pollinate itself. This is contrasted with cross-pollination which is where one plant's pollen lands on another plant's stigma. Plants often do specific things to avoid self-pollination if they can.
They attract insects to help pollinate the plant for reproduction
There will be no flowers and fruits.
