What is viviparous germination give example?
What is viviparous germination give example?

What is meant by Hypogeal germination?
Hypogeal germination (from Ancient Greek ὑπόγειος [hupógeios] ‘below ground’, from ὑπό [hupó] ‘below’ and γῆ [gê] ‘earth, ground’) is a botanical term indicating that the germination of a plant takes place below the ground. An example of a plant with hypogeal germination is the pea (Pisum sativum).
What is germination of seed Class 5?
Germination: The process in which a plant emerges from a seed and begins growth is called germination. Stages of Germination: During the early stages of germination, the seedling gets the food required for its growth from the cotyledons.
What is the germination theory?
Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule.
What are vivipary 3 examples?
Fish, amphibians, reptiles, and mammals all have viviparous members, while none of the group are exclusively viviparous. Developing the young viviparously appears to be a derived trait from oviparous animals. The theory is that some oviparous animals tend to develop eggs longer than others internally.
What is epigeal and hypogeal?
Definition. Epigeal germination refers to the germination of a plant that takes place above the ground while hypogeal germination refers to the germination of a plant that takes place below the ground.
What are the examples of epigeal and hypogeal germination?
An example of a plant with epigeal germination is the common bean (Phaseolus vulgaris). The opposite of epigeal is hypogeal (underground germination).
Which plants are viviparous?
Plant vivipary is the process of giving birth to young seedlings in advanced stages of development. It is commonly seen in mangroves like Rhizophora , Sonneratia and Heritiera.
Which is viviparous snake?
Vivipary means development of the embryo inside the body of the mother, eventually leading to live birth, as opposed to laying eggs. Most vipers and all of the rattlesnakes fall into this category. Members of the Boidae family, which includes boa constrictors and anacondas, also give birth to live young.

What is the difference between hypogeal and epigeal seed germination?
Hint: Cotyledons remain below the soil surface in hypogeal germination while they emerge on to the surface in the epigeal germination….Write the difference between epigeal and hypogeal germination.

Which seeds are epigeal?
– Epigeal germination is the type where the cotyledons are above the soil surface as the hypocotyl elongates very rapidly. The epicotyl remains unchanged in length. – Examples of epigeal germination are cotton, sunflower, castor, and bean (or common bean).
What is epigeal germination give example?
