7 Characteristics Of A Living Thing:
1. Obtain energy through food
2. Respire
3. Respond to their environment
4. Excrete Waste
5. Able to Repair Themselves
6. Grow and Reproduce
7. Have A Limited Lifespan
Cell Theory:
1) All living things are made up of one or more cells
2) The cell is the simplest unit that can carry out all life processes
3) All cells come from other pre-existing cells (cannot come from non-living matter)
Prokaryotic Vs Eukaryotic Cells
Prokaryotic Cells:
Do NOT contain a nucleus or other membrane-bound organelles, and are small and simple
cells called the prokaryotes Ex. Bacteria
Eukaryotic Cells:
DO contain a nucleus and membrane-bound organelles, large and complex cells, and are
found in most complex life forms called Eukaryotes.
Organelle: a specialized subunit within a cell that performs a specific function, much like an organ
does in the human body
, Organelles
Plant vs Animal Cells (Organelles + Functions)
Found in BOTH
● Cell membrane → controls what enters/exits cell
