"Sugar covering" at cell surface involved with cell recognition. Every cell type has different
,Question 5:
Allows immune system to recognize "self" and "non self" Glycoprotein
Glycolipid
a lipid attached to one or more carbohydrates Interstitial fluid
in water with high concentrations of sodium ions.
Cytoplasm
containing dissolved solutes, organelles, and inclusions Intracellular fluid
substances dissolved in water with high concentrations of potassium ions.
Inclusion membrane
Answer:
pattern of sugars with specific biological markers for cell recognition.
a protein with one or more carbohydrates attached that face the extracellular surface
or tissue fluid is a solution that bathes and surrounds the tissue cells. It is the main component
of the extracellular fluid, which also includes plasma. A complex mixture of substances
dissolved occupies space between cell membrane and nucleus; consists of cytosol (intracellular
fluid)
or cytosol is the liquid found inside cells and is part of the cytoplasm; a complex mixture of
in cytoplasm stored nutrients, secretory products, and pigment granules that are not bound by
Question 6:
Mitochondria, endoplasmic reticulum, golgi apparatus, centrosome, lysosome, vesicles,
peroxisomes
Answer:
Organelles in cytoplasm
Question 7:
Powerhouse of the cell; organelle that is the site of ATP (energy) production (cellular
Answer:
Mitochondria
Question 8:
Rough endoplasmic reticulum
Answer:
respiration); double-membrane structure; contains own DNA and ribosomessystem of
membranes that appear rough due to the presence of ribosomes which manufacture all
proteins secreted from cells; functions to manufacture all secreted proteins and membrane
integral proteins and phospholipids, and attach sugar groups to proteins in the cisterns.
Proteins

Smooth endoplasmic reticulumsteroids, detoxify substances, regulate cellular calcium levels
Answer:
are bound to vesicles for transport to the Golgi apparatus and other sites.network of
interconnected membranes forming channels within the cell that are free of ribosomes;
contains enzymes that function to produce transport vesicles, synthesize of lipids and
Question 10:

Question 11:
Stack of flattened membranes in the cell that modifies, sorts, and packages proteins and lipids
lysosomes, and incorporation into the plasma membranePeroxisomesis catalase for breaking
down hydrogen peroxide; eliminates free radicals Secretory vesiclesmembrane where they are
released or secreted from the cell
Answer:
Golgi apparatuscreated in the endoplasmic reticulum; segregates proteins for secretion from
the cell, inclusion in membranous sacs of catalase and oxidase enzymes; detoxify substances;
most important enzyme membrane bound bubbles that carry chemical substances like lipids
and proteins to the cell
Question 12:
A structure in animal cells containing centrioles from which the spindle fibers
develop.Cytoskeleton apart)cytoskeleton functions
Answer:
centrosomeprovides structural framework of the cell and gives it shape; consists of protein
microfilaments, intermediate filaments, and microtubules; resists mechanical forces
(compression and pulling cell shape, internal organization, intracellular transport, assembly of
cells into tissues, movement
