Mammal embryos don't require a large yolk becaues they are nourished directly by the mothers body. In contrast, birds, reptiles, and other (mostly) egg layers, need a large yolk because the yolk must nourish the embryo all the way through development.
When the yolk is where the embryo develops, it is called telolecithal development. In this type of development, the yolk is concentrated at one pole of the egg, providing nutrients for the developing embryo. Examples of organisms that exhibit telolecithal development include birds and reptiles.
No , reverse is true .
The egg yolk is the little baby that is going to born after it's mother heats it.
The yellow part of an egg is called the 'yolk' and its purpose is to feed the developing embryo (chick).
The yolk provides essential nutrients and energy for the developing embryo, serving as a food source during the early stages of development. It contains proteins, fats, vitamins, and minerals that support growth and cell division. Additionally, the yolk contributes to the formation of various tissues and organs in the embryo, facilitating overall development until it can obtain nourishment independently.
A yolk is to a bird as a placenta is to a mammal. The yolk provides nourishment to the developing embryo in bird eggs, while the placenta facilitates nutrient and gas exchange between the mother and the developing fetus in mammals. Both serve vital roles in supporting development before birth.
Embryo is formed in germinal spot of yolk .
Yolk or blood are food for embryo .
no the yolk is what the young chick eats.
The yolk is there to nourish the growing embryo.
A fertilized egg's yolk provides all of that embryo's nutrient, it also provides protection to the embryo. There are two types of yolk, white yolk and yellow yolk, both having their purpose.
The embryo is the yolk and feeds what would be the white of the egg if cooked.
The yolk of the egg.
A fish embryo feeds from the yolk in the egg. Once they are hatched, they still have a supply of yolk in a sac to last them for a few days.

The structure that surrounds the yolk and transports nutrients to the embryo is called the vitelline membrane. This membrane is responsible for facilitating the exchange of nutrients and waste products between the yolk and the developing embryo during embryonic development.
