difference between an animal cell and a plant cell
an animal cell does not have; chloroplast, vacuole or cell wall
function of the nucleus
controls cell activity
function of the cell membrane
controls what goes in and out of the cell
function of the mitochondria
where respiration takes place
function of the cytoplasm
where chemical reactions take place
function of ribosomes
where proteins are made
function of chloroplasts
where photosynthesis takes place
what do chloroplasts contain
chlorophyll
function of a vacuole
stores cell sap and keeps the cell firm
function of a cell wall
provides support
what is the cell wall made out of
cellulose
function of an egg cell that helps it adapt
- spongy outside layer; protects cell, attracts sperm
- large amount of cytoplasm with fat stores
function of a sperm cell that helps it adapt
- lots of mitochondria to release energy
- tail for swimming
- enzymes in the head to help sperm enter egg
functions for a muscle cell that helps it adapt
- mitochondria to release energy
- long cell to be able to contract and relax
functions for a nerve cell that helps it adapt
- long to transmit electrical signals long distance
- branched connections to connect to other nerve cells
functions for a red blood cell that helps it adapt
- contains haemoglobin, red pigment that binds oxygen
- no nucleus
- large surface area to carry oxygen
functions for root hair cell that helps it adapt
- large surface area to absorb water
- mitochondria to release energy
- no chloroplasts as it is underground it doesn’t do photosynthesis
what is a eukaryote
a complex cell
what are prokaryotic cells
small and simple cells
example of a prokaryotic cell
bacterial cell
examples of a eukaryotic cell
animal, plant and fungi cells
what is osmosis
the diffusion of water molecules from a high concentration to a low concentration
what is active transport
process to move molecules from a low concentration to a high concentration
does active transport need energy
yes
