Robert Hooke looked at these under a microscope and claimed they looked like tiny rooms
cork cells

 The smallest level of organization
atoms or cells

Control center of the cell and stores DNA
nucleus 
100
Gives the cell energy 
mitochondria 
100
Cell that has a nucleus 
eukaryotic cells
200
Virchow gave which part of the cell theory
all cells come from pre-existing cells
200
The largest level of organization
organism 
200
gives the cell shape and support. Found only in plant cells
cell wall
200
Stores water and waste
vacuole 
200
Prokaryotic cells
do not have a nucleus 
300
cells reproduce 
from pre-existing cells 
300
Organ systems all work together to form:
a organism 
300
Controls what enters and leaves the cell
cell membrane 
300
Found only in plants. Helps with photosynthesis 
chloroplast

The mouth, nose, trachea, and lungs are all organs. When they work together, the form a: 
organ system

The invention of the microscope contributed to which part of the cell theory 
all living things are composed of cells 
400
Group of cells that work together form:
tissues

The function of the endoplasmic reticulum 
to transport materials 
400
Protein synthesis (makes proteins) 
ribosomes

The main differences between a plant and animal cell 
chloroplast 

cell wall 

500
The three parts to the cell theory 
1. all living things are made up of cells

2. cells are the smallest unit of life 

3. cell comes from pre-existing cells

List the levels of organization from smallest to largest
cells-tissues-organs-organ system-organism 
500
why is the integumentary system similar to the cell membrane 
they both control what enters and leaves the cell

We need energy to run, jump, and play. This organelle has the same function within a cell to fuel cellular activities. 
mitochondria

 organelle is similar to the digestive system because it breaks things down.
lysosome
