Cytoplasm:
Cell differentiation:
Cells and extracellular matter together compromise all the tissue that make
up the organ of multicellular animals.
The first zygotic cellular division produce cells called blastomeres.
Embryonic stem cells are explanted to tissue culture cells of the inner cell
mass.
Differentiation is where cells differently express their set of genes that
meditate specific cytoplasmic activity becoming very effective in their
cytoplasmic activity and changing their shape accordingly.
Plasma membrane:
Plasma membrane contains phospholipids, cholesterol, and proteins
that contain oligosaccharides chains covalently linked to many
phospholipid and protein molecules.
This membrane functions as a selective barrier regulating the passage of
materials into and out of the cell and facilitate the transport of specific
molecules.
Important role is to keep constant the ion content of cytoplasm.
Carry out a number of signaling and specific recognition functions, plays
a key role in interactions of the cells with its environment.
Integrins are certain plasma membrane proteins that is linked to both
cytoskeleton and extracellular matrix components and allows exchange
of influences in both directions, between the cytoplasm and materials in
the extracellular matrix.
Membranes phospholipids are amphipathic, consisting of two non-polar
long chain fatty acids linked to a charged polar head that bears a
phosphate group
Glycolipids include oligosaccharide chains that extend outward from the
cell surface.
Glycocalyx is a delicate cell surface coating on glycolipids. Is important
for cell to cell interaction, for cellular migration. They have receptors,
