What is structure function and importance of extraembryonic membranes?
Extraembryonic membranes are specialized tissues that develop in some vertebrates to provide protection, nutrition, and waste removal for the embryo during development. These membranes include the amnion, chorion, yolk sac, and allantois. They are essential for the survival and proper development of the embryo by creating a suitable environment within the egg or uterus.
Are cell membranes found in plant cells or animal cells?
Cell membranes are found in both animal and plant cells. Plants have an extra, rigid layer called a cell wall as well.
What does the inner cell mass become?
It becomes the embryo proper and some extra-embryonic membranes. First it specializes into an epiblast and hypoblast. The epiblast becomes the embryo proper and the hypoblast becomes the yolk sac.
Sto cell line?
The STO cell line is a mouse embryonic fibroblast cell line commonly used in research settings for various applications, including the maintenance and propagation of embryonic stem cells. STO cells are known for their ability to support the growth and pluripotency of stem cells in culture due to their feeder layer properties, making them a valuable tool in regenerative medicine and cell biology research.
What is the purpose of polar bodies in the process of oogenesis?
Polar bodies are small cells produced during oogenesis that do not have the ability to develop into an embryo. Their purpose is to discard extra genetic material and ensure that the egg cell contains the correct amount of chromosomes for fertilization.
Which grop has four extra embryonic membranes aquatic or land animals?

What extra piece attached to the large intestine serves no discernible purpose and can be removed?
The appendix is the extra piece attached to the large intestine that serves no discernible purpose and can be removed without causing harm to the body.
