a term used to describe an organism that is made up of one cell
What is unicellular
100
Materials enter and leave the nucleus through this
What is the nuclear membrane?
100
this is the gel-like substance in a cell that provides the environment for all other organelles.
What is the cytoplasm?
100
All living things are composed of these
What are cells
200

What is the endoplasmic reticulum?
200
A large of group of one celled organisms that sometimes cause diease
What are bacteria?
200
The structure in a eukaryotic cell that contains the genetic material a cell needs to reproduce and function
What is the nucleus
200
This organelle generates energy in the cell.
What is the mitochondria?

This structure supports and protects the plant cell.
What is the cell wall?
400
organelles that release energy by using oxygen to break down sugars
What is the mitrochondra?

This allows materials to move into and out of the cell.
What is the cell membrane?
500
An instrument that uses glass lenses to magnify as object
What is a microscope
500
a cell in which the genetic material is enclosed within a nucleas, surrounded by it's own menbrane
What is a eukaryotic cell?
500
The nucleus is important to the cell for this reason.
What is it directs all cell activities?
500
This is the pigment in chloroplasts that enable plants to absorb sunlight
