There is no such thing as a "cleidoian egg." It may have been misspelled or misheard. If you meant to ask about a "cleidoic egg," it is a type of egg found in reptiles and birds that has a shell and several extra membranes to protect and nourish the developing embryo.
The main function of the ovule is to house and protect the female reproductive cells (eggs) of the plant. Once fertilized by pollen, the ovule develops into a seed, which contains the embryo of the plant.
Yes, turtles lay amniotic eggs. These eggs have a protective membrane called the amnion that surrounds the developing embryo and helps prevent dehydration.
No. An amniotic egg will normally have multiple parts, like a chicken egg. An aminiotic egg also is surrounded by amniotic fluid. A fish egg is a small embryo surrounded by a protective gel like substance that is similar to a shell.
Yes, most snakes are oviparous, meaning they lay amniotic eggs. These eggs are enclosed within a shell that allows for gas exchange and protects the developing embryo.
Reptiles were the first group whose eggs cushioned the embryo in fluid and protected it with membranes and a shell. This prevents eggs from drying out and allows them to be laid away from water.
no apples con not lay eggs
Eggs rot before apples.
Mammals (monotremes only), birds, and reptiles give birth to amniotic eggs, which contain a yolk to nourish the developing organism. Amniotic eggs protect the developing organism, as well as aid in gas and energy exchange. chorion
The mosquito will nourish the eggs it is carrying with the blood.
Eggs are egg-shaped because this shape is strong and helps protect the developing embryo inside. The rounded shape distributes pressure evenly, making the egg less likely to break.
The yolk supplies all the nutrients for the growing embryo.
No, it is not possible to create a viable embryo by mixing two female eggs with sperm. An embryo can only be created by fertilizing a female egg with sperm from a male.
Most reptiles simply abandon their eggs to 'fate' once they're laid. Some species of lizards and snakes will stay close-by and actively discourage anything from disturbing the 'nest'. The majority of animals know instinctively to avoid contact with reptiles.
