1. Looking Inside Cells

2. CELLS are the basic unit of all living things.
They contain tiny structures called “organelles”.

3. plant cell

4. animal cell

5. 4 organelles you don’t have to know until high school… due to new GA standards
These will be marked with (*bhs) in front of endoplasmic reticulum, golgi bodies, vacuoles, and ribosomes.
They will be mentioned, but you will not be graded on these 4 organelles.

6. Found in plant cells only:
cell wall- tough outer layer surrounding plant, fungi, and bacteria cells; supports and protects.. “outside wall”
chloroplasts- contain chlorophyll; capture sun’s energy for food production; photosynthesis… “kitchen/lunchroom/cafeteria”

7. Organelles found in BOTH plant and animal cells:
cell membrane- outer boundary; controls what goes in and out (selectively permeable).. “doorways”
nucleus- directs all cell activities; contains chromatin (chromosomes/DNA)…“control center/ principal’s office”
mitochondria- produce energy for the cell; powerhouse.. “electrical outlets”

8. (*bhs) endoplasmic reticulum – moves materials around in the cell
more organelles…..
(*bhs) endoplasmic reticulum – moves materials around in the cell
(*bhs) ribosomes- make protein for the cell
(*bhs) Golgi bodies- used for packaging materials to be distributed in or out of the cell

9. (*bhs) vacuoles- storage areas for water, food, and wastes
more organelles….
(*bhs) vacuoles- storage areas for water, food, and wastes
lysosomes- break down food and worn out cell parts “trash cans / janitors/recycle bins”
Cytoplasm – clear gel-like substance inside cell

10. Bacteria cells are DIFFERENT from plant and animal cells……
usually smaller
does NOT contain a nucleus….but it does
contain genetic material
cells without a nucleus are called “Prokaryotes” !!!!! (pro rhymes with no)

12. Bacterial cell …. no nucleus!

13. Prokaryotes vs. Eukaryotes
YES…they have a nucleus and many other organelles in the cytoplasm
All other cells!!
(protist,fungi,plant,animal)
NO…does not have a nucleus…genetic material scattered
bacterial cells only !
