Prokaryotic cells do not have...
a nucleus or mitochondria
prokaryotic cells compared to eukaryotic cells are
smaller, single celled, have rings of DNA called plasmids

What does an animal cell not have that a plant cell has?
cell wall, vacuole and chloroplasts
Function of the cell membrane
controls what enters and leaves the cell
Function of the nucleus
Controls the cells activities and contains the genetic material (DNA)
Function of the cell wall
Provides support to the plant, made of cellulose
Function of bacterial plasmids
provide bacteria with variation - usually conferring antibiotic resistance
Function of the ribosomes
protein synthesis - its a very small organelle
Function of the mitochondria
Site of respiration, energy is released here
Describe the feature of bacterial DNA
Circular/loop, not arranged into chromosomes and not found in a nucleus
All eukaryotic cells have
An organelle is
a part of the cell with a specific function
is mainly water and is where the chemical reactions occur
Substances move in and out of cells by
In exchange of materials between cells and their environment, substances must cross the

Plants have chloroplasts because
they need to photosynthesise
The function of the chloroplasts are
to trap light energy for photosynthesis
when plants trap light energy and react carbon dioxide and water to produce glucose and oxygen
