Biology- Cells- Specialised cells
Red blood cell
Used to carry blood around the body
Features
small and flexible, helps them to fit into small narrow places
very thing membrane so they can absorb gasses ( AKA Oxegen) easier
Sperm cell
To fertilises female eggs and carry DNA
Features
the long tail helps it to swim
sharp & aromatic head helps with speed and crack into the head
Nerve cell
Sends electrical warning signals to the brain
Features
the fat around the tail helps to make the message fast
branches to help make them pass the message on
Muscle cell
made to contract and relax for movement
Features
a lot of mitochondria for energy
can contract very quickly
Root hair cells
helps plants to absorb water
Features
large surface helps it absorb a lot of water
a lot of mitochondria help it to have a lot of energy
Xylem cell
transports water and minerals around the plant
Features
long hollow tubes
thing cell membrane, allows water to seep through easy
Phloem
Moves food the plant has created for its self
Features
sleeve tubes made for transport
leave sleeve has a rounded end
