Normally if the pollen grains in the androceium is higher than the stigma then they fall and stick to the stigma.However some agents like wind,movement by some agents or by insects help in pollination

Is one squash plant enough to produce or do you need two for pollination?
we need two plants, as the male and female plants are different.
What is the difference insect pollination and wind pollination?
Wind pollinated flowers sometimes look ugly because they don't need to attract bugs.
Advantages of cross pollination?
genetic variability is a readily appreciated condition. Harmfull (resessive) gentic traits are masked, harmful (dominate) traits are quickly culled. Hybred plants feel the benefit even in the first generation.
How do plants and animals depend on each other?
Plants convert carbon dioxide given off by animals into oxygen. This process helps both plants and animals to survive. some animals llike deer need plants for food. Plants depend on animals for pollination and dispersal of seeds. Many animals just eat them but some use them as their shelter and and some to escape from predators. Plants depend on animals for enery as when an animal dies plants uses its body's nutrients.
Differentiate cross pollination from self pollination?
Self pollination is where the plant is able to pollinate without another plant. This provides much less variation in the genetics of the species from generation to generation than cross pollination which is where the pollen from one plant is carried to another plant (bees usually do this) and fertilizes the other plant. It creates more genetic diversity because the genes from both plants, which are different, are involved in the forming of the seed, not just the genes from the one self-pollinating plant.--------------------------------------------IMPROVEDSelf pollination is the transfer of pollen from the anther to the stigma of the same flower, another flower on the same plant, or the flower of a plant of the same clone. Cross pollination is the transfer of pollen from the flower of one plant to the flower of a plant having a different genetic constitution.
What are the plants that need to have cross pollination?
Plants bearing bisexual flowers and having self incompatibility and also dioceous plants bearing unisexual flowers.
What are the plants that do not need to have cross pollination?
Plants having cleistogamous flowers
What are two reasons the plants needs butterflies?
Plants need butterflies for two main reasons such as pollination. Plants also need butterflies to bring other animals into the ecosystem.
Do flowers need insects to pollinate them?
Not all flowers require insects for pollination.Most angiosperms (flowering plants), in particular dicotyledonous plants, require an agent of pollination; normally these are animals - mainly insects, but can also be birds, mamals, centipedes etc.Monocotyledonous angiosperms which comprose largely of grasses are pollinated mainly by wind.Gymnosperms (cone bearing plants) rely mainly on wind pollination and therefore produce large quanitites of pollen.
Why do you need bees live?
Bees (and other flying insects) are needed for the pollination of fruit, flowers, trees and various other plants. Without pollination, plants couldn't survive and we wouldn't have enough food to eat.
What is the Need and significance of pollination?
if plants weren't pollinated they wouldn't be able to reproduce and would die
Is one squash plant enough to produce or do you need two for pollination?
we need two plants, as the male and female plants are different.
Why moss plants need water for reproduction?
The water carries the gametes(sperm) to the other mosses for pollination.
Why do plants rely on bumblebees?
because they have pollen and flowers need pollen and pollination, germination and respiration its a part of their life
On an island where there are no insects and birds the pawpaw plants produces only flower but no fruit?
They need birds and insects to pollinate the trees. Plants that are not pollinated can't produce fruits or vegetables.
Why do flowers start blooming in spring not in another season?
spring is the height of insect activity which flowering plants need for pollination
How do plants animals depend on each other In desert region?
Animals depend on plants because plants breath in carbon dioxide and breath out oxegon animals need to breath. Plants depend on animals for seed dispersal and pollination.
