Which is odd out of chalazogamy,porogamy,mesogamy,allogamy
Answers
The odd one out of all of them is Allogamy.
The reason why it is different:
Allogamy stands out as unusual. Because Pollen tube entrance from the micropylar end is known as porogamy. Pollen tube entrance occurs during mesogamy from the middle (integuments). Pollen tube entrance from the chalazal end is known as chalazogmy. A sort of pollination is allogamy.
The explanation for chalazogamy, porogamy, mesogamy, allogamy:
Pollen tubes enter the body through the integuments during mesogamy. Fertilization or gamete fusion is the fusing of male and female gametes. Therefore, "entry of the pollen tube through the integument" is the appropriate response.
Following fertilization, a zygote develops, producing seeds and subsequently embryos. The juvenile sporophyte is fed by the endosperm. Porogamy, which is typical of angiosperms, occurs when the pollen tube enters the ovule through the micropyle end.
The passage of the pollen tube through the integuments or chalaza is known as chalazogamy. Treub was the one who found this. Consider the casuarina. In Ulmus, partial chalazogamy is present.
An ovum from one person being fertilized by the spermatozoa of another is referred to as fertilization in the context of biological reproduction. Allogamy is the movement of pollen grains from the anther of one plant's flower to the stigma of another plant of the same species.
