cytoplasm Flashcards
(24 cards)
organelle that modifies, packages & sorts proteins for secretion or use within the cell :
Golgi apparatus
Name the RNA nitrogenous base that isn’t found in DNA
Uracil
Name the DNA nitrogenous base that isn’t found in RNA
Thymine
RER is studded with
Ribosomes
Ribosomal RNA is formed in
the nucleolus
The organelle responsible for lipid metabolism
Smooth endoplasmic reticulum
Mitochondria can divide by
simple binary fission
Name three non-membranous organelles
Ribosomes, microtubules(Centrioles) & microfilaments .
Give 4 functions of smooth endoplasmic reticulum
1-lipid synthesis 2-drug detoxification
3-glycogen store 4-calcium distribution
gologi apparatus is the site of
packaging of secretory products of the cell.
organelle that synthesizes proteins
Ribosomes
The function of rough endoplasmic reticulum is
synthesis of protein that will be secreted by the cell.
At EM level Golgi apparatus can be demonstrated as
smooth flattened saccules arranged in sacks.
DNA could be found in
mitochondria
mitochondria can divide because they have
DNA
The localized cytoplasmic basophilia indicates the presence of
Rough endoplasmic reticulum
Give 2 functions of cell membrane :
1)Acts as a protective barrier around the cell.
2)It controls what enters and leaves the cell allowing only certain substances by variety of methods as diffusion, osmosis & active transport mechanism.
The sugar in RNA is
Ribose
DNA sugar is
deoxyribose
‘Silver’ is the special stain for
Golgi apparatus
Give 2 functions of lysosomes :
1)Phagocytosis
2)Pinocytosis
Sudan III stain is specific to show :
Reticular fibers & fat cells
Hydrolytic enzymes are found in :
Lysosomes
The four basic tissues are :
1-epithelial tissue 2-connective tissue
3-muscle tissue 4-nervous tissue.
