state 3 cells in the animal cell
nerve cells,sperm cells,muscle cells,
nucleus for egg cell function
half set of genes of mother
egg cell mitochondria function
carries out aerobic respiration to release energy
egg cell function
fertilise by a male sperm cell to produce a fertilised egg
egg cell location
female ovaries
animal spesicilation
when a cell develops adpatations to carry out certain functions
mitochondria in a nerve cell
provides lots of energy
differentiation
when cells become specialised
nucleus adaptation sperm cell
half set of genes from father
sperm cell feature of the tail(flagellem)
long tail that allows them to swim to the ovum
why do sperm cells need lots of mitochondira
gives energy for swimming to reach the ovum quicker
sperm cells function
fertilise a egg to produce fetilised egg cell
location of sperm cell
males in testes
what are nerve cells specialised to do?
send electrical impulses to nervous system
what do muscle cells do?
contract and relax to allow movement
how do the fibres contract?
they have special proteins that slide over eachother
why do mucsle cells have lots of mitochondira
release energy for movement
acrosome function
it has digestive enzymes needed to digest cell membrane at the egg so it can swim
dendrites
make connections to other nerve cells
axon
sends messages quickly
synapses,(by what)
adapted to pass impulses to another cell by special transmitter chemicals
