What concept explains the presence of mitochondria in cell?

Do plants and animals have cell membranes?
Yes they do, just about all living cells (which i can remember anyways, plants and animals included) have cell membranes
What are the extra membranes in reptiles?
It's called the Nictitating membrane
What is the large peripheral blood vessels into which extra-embryonic blood vessels open?

What extra embryonic membrane is the first site for red blood cell formation?

Are cell membrains found in animals and plants?
Yes, cell membranes are found in both animal and plant cells. Plant cells also have an extra layer of cell wall surrounding the cell membrane.
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.

What is structure function and importance of extraembryonic membranes?
Extra-embryonic membranes include Chorion , Amnion , Allontois and Yolk sac . They are formed in Amniotes including Reptiles , Birds and Mammals . They are formed only during development and are of essential for development of Amniotes .1 : Chorion : It is outermost extra-embryonic membrane . It is formed by ectoderm and mesoderm . Its major function is protection in reptiles and birds . In mammals it helps in formation of Placenta and umbilical cord along with allontois .2 : Amnion: It is made up of mesoderm and ectoderm . It contains amniotic fluid for protection which acts as shock absorber . It has evolutionary significance .3 : Allontois; It is made up of endoderm and ectoderm .In reptiles and birds it helps in respiration and excretion . In mammals it helps in formation of umbilical cord .4 Yolk Sac : It is made up of endoderm and ectoderm . It is more important in reptiles and birds as it protects yolk . In mammals it is not importantPlacenta in mammals help in nutrition respiration and excretion .
How does ice protect aquatic animals?
Ice protects aquatic animals by isolating (ice is a good thermic isolater) the bottom of the pond from the atmosphere, and preventing the bottom of the pond from freezing and becoming ice.beause they are used to water
