What is the difference between allogamy and autogamy?
Autogamy refers to the self-pollination between the anther and stigma of the same flower, whereas allogamy refers to cross-pollination. In allogamy, the transfer of pollen occurs from the anther of one flower to the stigma of another flower of the same or another plant.
What is the difference between geitonogamy and autogamy?
Autogamy refers to the transfer of pollen grains from the anther to the stigma of the same flower, whereas geitonogamy refers to the transfer of pollen grains from the anther to the stigma of another flower of the same plant.
What is autogamy geitonogamy and allogamy?
(a) Allogamy: The transfer of pollen grains from the anther of a flower on one plant to the stigma of a flower on another plant of the same species is called allogamy. (b) Geitonogamy: The transfer of pollen grains from the anther of a flower to the stigma of another flower on the same plant is called geitonogamy.
What is the difference between geitonogamy and allogamy?
When pollens of a flower pollinate any other flower present on the same plant, it is said to be geitonogamy. Whereas transfer of pollen grains from the anther of a flower from one plant to the stigma of the flower on another plant is called . allogamy.
What allogamy means?
British Dictionary definitions for allogamy allogamy. / (əˈlɒɡəmɪ) / noun. cross-fertilization in flowering plants.
What is autogamy example?
Self-pollination is an example of autogamy that occurs in flowering plants. Self-pollination occurs when the sperm in the pollen from the stamen of a plant goes to the carpels of that same plant and fertilizes the egg cell present. Self-pollination can either be done completely autogamously or geitonogamously.

What is the difference between allogamy and geitonogamy?
What is allogamy in biology?
Allogamy or cross-fertilization is the fertilization of an ovum from one individual with the spermatozoa of another. By contrast, autogamy is the term used for self-fertilization. In humans, the fertilization event is an instance of allogamy.
What is the difference between autogamy geitonogamy and xenogamy?
Autogamy: Autogamy is the fertilization of a flower by pollen from the same flower. Geitonogamy: Geitonogamy is the fertilization of a flower by pollen from another flower on the same plant. Xenogamy: Xenogamy is the fertilization of a flower by the pollen of a flower from a genetically different plant.
What are the examples of allogamy?
In humans, the fertilization event is an instance of allogamy. Self-fertilization occurs in hermaphroditic organisms where the two gametes fused in fertilization come from the same individual. This is common in plants (see Sexual reproduction in plants) and certain protozoans.
Is allogamy and geitonogamy same?
What is autogamy give example?
Self-pollination is an example of autogamy that occurs in flowering plants. Self-pollination occurs when the sperm in the pollen from the stamen of a plant goes to the carpels of that same plant and fertilizes the egg cell present.
What do mean by autogamy?
Definition of autogamy : self-fertilization: such as. a : pollination of a flower by its own pollen. b : conjugation of two sister cells or sister nuclei of protozoans or fungi.
What is the similarities of autogamy and Allogamy?
Similarities Between Allogamy and Autogamy Allogamy and autogamy are two methods of fertilization that occur in the flower. Both reproductive structures of the flower, stamen, and pistil participate in each method of fertilization. Generally, the method of pollination determines the method of fertilization.
What is the example of allogamy?
What is allogamy give example?
It is a terminology utilised in the field of biological reproduction describing the fertilization of an ovum from one individual with the spermatozoa of another. The transfer of pollen grains from the anther of a flower on one plant to the stigma of a flower on another plant of the same species is called allogamy.
Is Allogamy and geitonogamy same?
What is the example of autogamy?
What are two types of autogamy?
Types of Autogamy pollination: There is two types of autogamy pollination 1) Cleistogamy and 2) Chasmogamy.
The main difference between allogamy and autogamy is that allogamy refers to the fertilization of a flower by pollen from another flower, especially one on a different plant, while autogamy refers to self-fertilization. Furthermore, cross-pollination occurs in allogamy while self-pollination occurs in autogamy.
What is the best example of allogamy in plants?
The best example of allogamy is the fertilization that occurs in human. Nevertheless, in plants, allogamy is categorized into two parts; geitonogamy and xenogamy. Geitonogamy refers to the transfer of pollen from the anther to the stigma of another flower of the same plant.
What is autogamy in plants?
Autogamy is a type of self-fertilization in which the egg cell in the flower fuses with the sperm cell derived from the anthers of the same flower. Thus, the flowers that follow autogamy have to undergo self-pollination.
Is allogamy a type of cross fertilization?
Allogamy is a type of fertilization that occurs between an egg cell of one individual and a sperm of another individual. Therefore, it is a type of cross-fertilization.
