What is meant by self pollination and cross pollination?

Upvote4 Downvote2

Self-pollination - transfer of pollen from the anther to the stigma of the same flower, or to another flower of the same plant. Cross-pollination - transfer of pollen from the anther of a flower to the stigma of a flower on a different plant of the same species.

Hereof, what is the difference between self and cross pollination?

It is the transfer of pollen grains from anther to the stigma of either the same or genetically similar flower. Cross pollination involves the transfer of pollen from anther of one flower to the stigma of a genetically different flower. Self pollination can occur even in closed flower.

How is self fertilization different from cross fertilization?

Cross Pollination vs. Self-Pollination. Pollen is transferred to the female reproductive organs of seed plants resulting in fertilization and reproduction in a process called pollination. Specifically, from the pollen grains of the anther to the stigma of a flower of a different plant of the same species.

Is there a difference between pollination and fertilization?

Well, for starters, fertilization occurs deep within a flowering plant AFTER pollination occurs. Firstly, pollination is the transfer of pollen from the anther (male organ of the flower) to the stigma (female organ of the flower) of the same or different flower. This process is called fertilization.

What is the difference between self and cross pollination?

Self pollination is the process of transferring the pollen's from anther to stigma in the same flower.Cross pollination is the transfer of pollen grains from the anther of a flower to the stigma of another flower in a different plant of same or different species.

What do you mean by self pollination and cross pollination?

Self-pollination - transfer of pollen from the anther to the stigma of the same flower, or to another flower of the same plant. Cross-pollination - transfer of pollen from the anther of a flower to the stigma of a flower on a different plant of the same species.

What are the differences between self and cross pollination?

Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

4

Why is it better to cross pollinate than self pollination?

In this way cross breeding is better and effective to the nature and to human beings. cross-pollination is advantageous because it allows for diversity in the species, as the genetic information of different plants are combined. However, it relies on the existence of pollinators that will travel from plant to plant.

5

How do you avoid self pollination?

Few plants self-pollinate without the aid of pollen vectors (such as wind or insects). Pollination can also be accomplished by cross-pollination. Cross-pollination is the transfer of pollen, by wind or animals such as insects and birds, from the anther to the stigma of flowers on separate plants.

6

How does the process of fertilization takes place in flowers?

When ripe pollen from an anther of the same kind of flower catches on the stigma, each pollen grain sends out a tiny threadlike tube. The tube grows down through the style and pierces one of the ovules in the ovary. This process is called fertilization.

7

How did Mendel prevent self pollination?

Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice.

8

Why is cross pollination an advantage?

Cross pollination is advantageous because it allows for diversity in the species, as the genetic information of different plants are combined. However, it relies on the existence of pollinators that will travel from plant to plant.

9

What is the difference between pollination and fertilization in flowering plants?

Firstly, pollination is the transfer of pollen from the anther (male organ of the flower) to the stigma (female organ of the flower) of the same or different flower. Secondly, fertilization occurs once the pollen grain reaches the stigma, it produces a pollen tube, which grows down through the style to the ovary.

Why is cross fertilization different from self fertilization?

Cross Pollination vs. Self-Pollination. Pollen is transferred to the female reproductive organs of seed plants resulting in fertilization and reproduction in a process called pollination. Specifically, from the pollen grains of the anther to the stigma of a flower of a different plant of the same species.

11

What are the advantages of cross pollination?

It allows for diversity in the species, as the genetic information of different plants are combined. However, it relies on the existence of pollinators that will travel from plant to plant. More uniform progeny. Allows plant to be less resistant as a whole to disease.

12

How can cross pollination occur naturally?

Cross-Pollination. Often, pollination is facilitated through natural means such as wind, rain, animals and bees, but some species of flower may also self-pollinate. Cross-pollination occurs when one type of flower pollinates another type, resulting in a hybrid plant.

13

Is self pollination asexual?

Asexual & Sexual Reproduction. Asexual Reproduction is the process resulting in the production of genetically identical offspring from one parent, without the fusion of gametes. Transfer of pollen grains from the anthers to the stigma is called pollination. There are 2 types: cross-pollination & self-pollination.

14

What are some of the ways that pollen can travel from one flower to another?

People can transfer pollen from one flower to another, but most plants are pollinated without any help from people. Usually plants rely on animals or the wind to pollinate them. When animals such as bees, butterflies, moths, flies, and hummingbirds pollinate plants, it's accidental.

15

What crops do not need pollination?

Other bees tend to favor one species at a time, therefore do most of the actual pollination. The most essential staple food crops on the planet, like corn, wheat, rice, soybeans and sorghum, need no insect help at all; they are wind-pollinated or self-pollinating.

16

What is meant by cross pollination?

cross-pollination. The transfer of pollen from the male reproductive organ (an anther or a male cone) of one plant to the female reproductive organ (a stigma or a female cone) of another plant. Insects and wind are the main agents of cross-pollination.

17

What are the different types of pollination?

There are two types of pollination, called self-pollination and cross-pollination. Self-pollination is the more basic type of pollination because it only involves one flower. This type of pollination occurs when pollen grains from the anther fall directly onto the stigma of the same flower.

18

What happens to a plant after pollination?

Only after pollination, when pollen has landed on the stigma of a suitable flower of the same species, can a chain of events happen that ends in the making of seeds. A pollen grain on the stigma grows a tiny tube, all the way down the style to the ovary. The ovary develops into a fruit to protect the seed.

19

Why do plants bear flowers?

Pollen is a collection of male reproductive cells that will fertilize ovules to produce seeds. When the flower blooms, male pollen cells are scattered by insects or by the wind. Some kinds of plants produce only complete flowers. Other plants produce both male and female incomplete flowers on the same plant.

20

What are the agents of pollination?

Pollination agents – insects,bees, moths, butterflies, birds and bats. Insects, visit the flowers not to effect pollination but to collect nectar, edible pollen or for shelter.
