Cells Flashcards
(24 cards)
Golgi apparatus
receives proteins from RER
produces vesicles by packaging protein
modification of proteins
production of lysosomes
RER
Synthesis and transport of proteins
SER
production and storage of lipids and carbohydrates
vacuole
storage of salts/sugars/pigments
provides turgor support
controls water potential
what does mitochondria contain
outer membrane
matrix
folds of inter membrane
ribosomes
cristea
ATP synthase
loop of DNA
what does chloroplast contain
outer membrane
inner membrane thylakoid
granum
lamauee
ribosomes
circular DNA
starch grain
slime capsule
protection from dehydration
contains hydrolytic enzymes for protection from engulfment from WBC
plasmids
contains genetic information
can be copied and passed on to other bacteria no matter the strain
nucleoid DNA
contains essential genetic information that can be used for next generation
controls cell activities
mesosomes
aerobic respiration
release energy
produce ATP
Pili
small hairlike projections which enable bacteria to stick together
enable DNA to be transferred between then
what are the types of wp
types of epithelial tissue
Squamous
Ciliated
Striated
squamous
one cell thick
flattened shaped cells
forms wall of alveoli
function of squamous
large surface area and short distance for diffusion of gases
increase absorption of substance
ciliated structure
hairlike projections on surface of cells
goblet cells make mucus
structure of striated
several layers thick
layers highly folded
striated functions
forms outer layer of skin covering the body
forms protective lining of small intestines
constantly renewing itself to replace damaged cells
what is connective tissue made up off
cells (fibrocytes)
fibres (elastin and collagen)
held in a gelatinous matrix
connective tissue function
gives support and strength
holds organs in position
flexibility
Types of muscles cells
Skeletal
smooth
cardiac
bone composition
bone marrow
matrix containing Ca2+
osteocytes
connective tissue
bone function
support the body
protect internal organs
allows movements
produce blood cells
storage of Ca2+
Action potential
Na+ diffuses into the neurone causing the depolarisation
Action potential created
K+ diffuses out of the neurone causing the repolaristation
Charge moved along the nerve
