1) All cells are made of cells
2) Cells are basic unit of life
3) Cells come from preexisting cells
Schleiden, Virchow, and Schwann
concluded the cell theory
Plant Cell > Animal Cell > Bacteria Cell
How do cells compare in size?
control center; contains DNA
regulates what enters and leaves the nucleus
gel-like material and organelles inside the cell membrane
power plant; cellular respiration
What material is burned for fuel in mitochondria?
Mitochondria store the energy released when they burn glucose as _______.
What are Golgi Bodies made of?
sort and package molecules for export
log-like structures made of proteins; pull apart chromosomes during cell division
Free in the cytoplasm or attached to rough ER
Where are ribosomes located?
sac of digestive enzymes; break down food, unwanted cells or cell parts
programmed cell death; for good of the cell
Synthesizes proteins for transportion to cell or exportation
make lipids and proteins used by cell; regulate calcium; break down toxins
photosynthesis to make food
stores water, food, and wastes
HUGE in Plant Cells, small in Animal Cells, and NOT in bacteria cells
How large are vacuoles?
Plants and Bacteria
Which cell(s) have cell walls?
Nucleus, Mitochondria, and Chloroplasts
has a double membrane and their own DNA
Plants and Animals
Volume increases faster than surface area so cells must divide in order to have enough surface to move materials into and out of the cell.
Why is the size a cell can grow limited?
