assessment test terms solved .
Human cell organization - n
ans ✔✔
Cell membrane, nucleus, cytoplasm; cytosol, organelles
Qs
cell membrane - n
ans ✔✔
Lipid bilayer (double layer)
Made up mainly of phospholipids and cholesterol
proteins
Extend into or through the lipid bilayer
The main cell membrane functions are:
to give the cell shape
to protect the cell
to control what enters and leaves the cell
Qs
cell membrane image - n
ans ✔✔
Qs
cilia - n
ans ✔✔
Short, hair-like projections from the cell membrane
, Move fluids along outer surface of the cell, for example:
Moves mucus out of the respiratory tract
Moves the egg along uterine (fallopian) tubes
Qs
microvilli - n
ans ✔✔
Finger-like projections of the cell membrane which increase the surface area of the cell
Found in the small intestine
The increased surface area helps increase the rate at which the products of digestion
are absorbed into cells
Qs
flagella - n
ans ✔✔
Longer than cilia, move an entire cell
Only example in humans is the tail of sperm cells
Qs
cytoplasm - n
ans ✔✔
Is all the cellular contents between the cell membrane and the nucleus
Qs
cytosol - the fluid portion (mostly water) - n
ans ✔✔
Intracellular fluid, surrounds the organelles
The site of many chemical reactions
Qs
organelles - intracellular structures - n
