Usually this is done by hand, the sac is very hard and needs to be carefully cut open by using a sharp exacto knife in order to display the powdery pollen. A small brush, q-tip or similar is used to transfer the pollen to the stigma.

What will happen to the plant if it does not have the phloem tube?

Then the pollen would not be able to reach the ovule therefore it will not be able to make a seed


How do the sperms nuclei in a pollen grain reach the egg nucleus in an ovule?

When they land on the style they begin to bore their way through the stigma all the way to the ovule. Through the tube made by the tube nucleus of the pollen grain: each pollen grain has two nuclei, one called generative nucleus which combines with the nuclei of the ovule, and the other called tube nucleus tube nucleus which forms a tube that penetrates the stigma till it reaches ovule then it degenerates.

After pollen grows a tube down the style?

Pollen grows a tube that travels down to the flowers ovary. From there, the nucleus of the pollen grains passes through the pollen tube to join the nucleus of the ovule to fertilize.


How does pollen that fertilizes the egg reach the ovule?

Some of the pollen grains carried by wind,insects,birds or bats may reach a carpel and stick to the ripe stigma.Each pollen grain produces a tiny tube which grows down to the style,into the ovary and towards the ovules or egg cells.when one of the tubes reaches an ovule,it bursts open.A male nucleus from the pollen grain then moves down the pollen tube to join with the nucleus of the female sex cell,the ovule.when the nuclei of the pollen grains and ovules have joined together, the ovules are said to be fertilized.


Why is wind dispersed pollen an important phenomenon in the evolution of plants?

Earlier plants required water for reproduction. Gymnosperms can just use wind instead to reach an ovule where it will germinate.


How does fertilization in plants?

the pollen grains after landing on the stigma germinate to send out pollen tubes through which the male gametes reach near the egg cell of embryo sac in the ovule to fuse with. this fusion of male and female gametes (egg cell) is called fertilization.


What is the functionof the tubes that grow from pollen grains?

They provide a pathway for the male gamete to travel down through the style. This is necessary for the gamete to reach the female cell (ovule) in the ovary for fertilization to take place.


How does fertilization take place in a flower?

the pollen grain lands ot the tip of pistle called as stigma and then pollen tube from pollen grain germinates and it reaches the ovary through style(containing 2 male gamets).. then fertilisation takes place... or is when the male sex cells inside the pollen grains fuses with the female sex cells inside to produce a seed embryo Pollination transfers the pollen grain to the stigma. However, for hertilisation to take place, the nucleus of the pollen grain must fuse with the nucleus of the ovum, which is inside an ovule in the ovary. To transfer the nucleus to the ovum, the pollen grain grows a tube, which digest its way through the tissue of the style and into the ovary. Here it grows around the opening in an ovule. The tip of the tube dissolves and allows the pollen grain nucleus to move out of the tube and into the ovule. Here it fertilises the ovum (egg cell) nucleus.


What structure transports sperm in the ovule in flowering plants?

The pollen tube is a structure designed to help a particle of pollen, the male side of the plant fertilization process, to access the egg cell in the female part of the plant. The egg cells are typically protected by cell walls and shells designed to keep them in place and protect them from outside elements. Pollen particles create pollen tubes to reach through these walls and access the egg cell.


How does pollen help a seed plant reproduce without water?

Pollen is the male reproductive structure of seed plants. It contains the sperm cells necessary for fertilization. When pollen is transferred from the male reproductive structure to the female reproductive structure (such as by wind or pollinators), it can reach the ovule without the need for water, allowing for fertilization and seed formation to occur.


How does the pollen not Reach the stigma of another flower?

pollen can reach the other flower during cross pollination
