animal cell specialisation

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
