Term
Cell Theory
Definition

All living things are composed of cells

A cell is the basic unit of life

Cells come from other cells

 

Term
Cells are small
Definition

most cells are between 1-100 micrometers 

 

Term
Eukaryotes
Definition

they are larger than normal cells and are more complex and they have organelles

and they make up plants and animals

 

Term
Cell size
Definition

it can be measured by a microscope 

and the unit for it is usually micrometers

 

Term
Prokaryotes
Definition

It is a bacteria

they can be good or bad but mostly good

and they are small

Term
pili
Definition
it is like a little hair like thing on bacteria
Term
plasmid
Definition

a genetic structure in a cell that can replicate independently of the chromosomes, typically a small circular DNA strand in the cytoplasm of a bacterium or protozoan.


Plasmids are much used in the laboratory manipulation of genes.

Term
Binary Fission
Definition

it is how the prokaryotes reproduce

by splitting up.

 

Term
cell wall
Definition

It is like a fence around a school.

it protects the organelles, which in this situation would be the kids in the school.

Term
Bacteria shapes
Definition

bacilli: rod shaped

cocci: round shaped

spiral: spiral shaped

Term

Antibiotic resistance

 

Definition

its is when the bacteria(prokaryotes) evolve and become immune to antibiotics

some things its when the bacteria just fight the antibiotics

or when the bacteria loose and there is only 1 bacteria left who evovles and become immune then reproduces

 

Term
nucleus
Definition
it is like an engine in a motor because it makes the cells work.
Term
cell membrane
Definition

they keep things out of the cell their head is hydrophilic and the tail is hydrophobic

the head is polar 

tail is non-polar

Term
cell wall-plants
Definition
Term
lysosomes
Definition
it breaks down the waste in a cell
Term
ribosomes
Definition
they make the things the cell needs
Term

smooth ER

rough ER

Definition

it is like a creation center

rough ER has ribosomes

 

 

Term
nucleolus
Definition
it is like a copy machine because it makes copies.
Term
Golgi Body
Definition

it is like packaging system 

because it packages stuff

Term
vesicle
Definition
it transports things through the cell like a bus transports passengers
Term
centriole
Definition

they are organizers of cell division(mitosis)

and the transport things from one end to another

 

Term
  1. mitochondria
Definition

they are like power plants

because they give power to the cell
