What is a eukaryotic cell?
All and animal and plant cells are eukaryotic cells, eukaryotic cells are cells with nucleus.
1 of 15
What is a eukaryote?
An organism made up of eukaryotic cells (each cell in it has a nucleus)
2 of 15
What are prokaryotic cells?
Bacteria. These are the only cells that do not have a nucleus. They are also smaller that eukaryotic cells.
3 of 15
What are prokaryotes?
Bacteria cells. These are separate cells with no nucleus.
4 of 15
What is cytoplasm and what does it do?
Fluid, mainly water, it's purpose is to hold other components like ribosomes. Chemical reaction happens in here too, like the production of protein in ribosomes). In both eukaryotes and prokaryotes

What is a cell wall and what does it do?
They provide support in plant,fungi(eukaryotic) and bacteria(prokaryotic)cells, it is the outer shell. In prokaryotes however it is not made of cellulose.Not in animal cells they only have a cell membrane(eukaryote).
6 of 15
What is a single DNA loop and what does it do?
it is just a simple ring of DNA, found only in prokaryotic cells.
7 of 15
What are plasmids and what does it do?
These are small, circular sections of DNA. This provides genetic variation for prokaryotic cells. Can only be found in prokaryotes but not all have them.
8 of 15
What are ribosomes and what do they do?
Proteins are made in ribosomes, present in cytoplasm. In both eukrayotic and prokaryotic cells.
9 of 15
What is a cell membrane and what is its purpose?
All cells have this. It controls what goes in and out of the entire cell.
10 of 15
what is diffusion?
The net movement of particles from an area of high concentration to an area of low concentration.
11 of 15
How does diffusion work in animal cells?
many of animal cells need glucose and oxygen for respiration, these substances move by diffusion, or are transported into the cells from the blood.
12 of 15
What is an organelle?
A part of a cell with a specific function. e.g mitchondrion
13 of 15
What are mitochondria?
these are small organelles only found in the cytoplasm of eukaryotic cells.This is where respiration happens.
14 of 15
What are chromosomes?
Present in almost all eukaryotic cell,
