Eggs typically have two membranes surrounding the egg white (albumen) and yolk: the outer membrane and the inner membrane. These membranes help protect the contents of the egg and serve as a barrier against bacteria. The outer membrane is located just beneath the eggshell, while the inner membrane is closer to the egg white. Together, they play a crucial role in maintaining the egg's freshness and quality.
What else can I help you with?
Eggs that cushion the embryo in fluid and protect it with membranes and a shell developed first in?
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.
Why doesn't a reptile have a shell membrane?
Reptile eggs have shell membranes.
What replaces the membranes and nutrition source of amniotic eggs in organisms that exhibit live birth without amniotic eggs?
allantois
How many shell membranes in egg?
Eggs have selectively permeable membranes, just like those of cells (they can only allow certain materials or objects to pass through, kind of like a screen door).
How many membranes does a mitochondrion have?
A mitochondrion has two membranes.
Why does an egg have film on it?
Eggs have two transparent protein membranes that serve to protect the inner parts from bacteria.
How many membranes are in the chloroplasts?
Nucleus is surrounded by a double membrane.
How many membranes does cyoplasm have?
7
Are all hen eggs in hard shells fertilized eggs?
NO- the vast majority of the commercial eggs are infertile- the hen never sees a rooster. Fertilization of the egg happend BEFORE the shell membranes and shell are added. Fertilization is not needed to form a shell.
Do blue-tongued lizards lay eggs?
No , Blue tongue lizards do not lay eggs like many other types of lizards. They give birth to live lizards.
Do owls have amniotic eggs?
Yes, owls do have amniotic eggs. Like all birds, they lay eggs that are encased in a hard shell, which provides protection and prevents desiccation. Amniotic eggs are a characteristic of reptiles and birds, allowing them to reproduce in a terrestrial environment. The eggs contain membranes, including the amnion, that help support the developing embryo.
How many membranes do chloroplasts contain?
double!
