2. PROKARYOTES vs
EUKARYOTES
Biology
Section 7.3

3. Prokaryotes – do not contain any organelles with membranes
All cells contain organelles BUT not all organelles are surrounded by membranes
Prokaryotes – do not contain any organelles with membranes
Most of these are unicellular (one celled) like bacteria

4. Eukaryotic cells – contain membrane-bound organelles
Most of these are multicellular (many celled)
Because organelles have distinct compartments, chemical reactions can be carried out at the same time in different organelles.

5. Comparison of size
Eukaryotic cells are generally 100x larger than prokaryotic cells.

6. Cells

7. Prokaryote vs. eukaryote
Both have cytoplasm, ribosomes, cell membrane, DNA
Prokaryotes X smaller
Prokaryotes DNA in circular chromosome in nucleoid region, eukaryotes DNA in linear chromosome in nucleus
Prokaryotes= no membrane bound organelles (ex. Nucleus), Eukaryotes have membrane bound organelles

8. First: Cell Boundaries
Plasma Membrane
Boundary of cell, allows materials to cross

9. Cell Wall
Additional support and protection to plant cells,
Outside cell membrane

10. manages cell, contains DNA
Nucleus
Cell Control
manages cell, contains DNA

11. Chromatin
jumbled strands of DNA
In nucleus
Chromatin

12. Nucleolus
Makes ribosomes, inside nucleus

13. Ribosomes
Ribosomes
Makes proteins

14. Nuclear Envelope
Surrounds nucleus

15. Assembly
in the cell

16. Clear, gel-like fluid inside a cell, chemical reactions
Cytoplasm
Clear, gel-like fluid inside a cell, chemical reactions

17. Endoplasmic Reticulum
Folded membranes, transports materials through out cell

18. 2 Types of ER Rough ER Ribosomes attached, makes proteins
Smooth ER No ribosomes attached, makes lipids (detoxification)

19. Golgi Apparatus
Flattened stack of membranes, Sorts and packages

20. Vacuoles
Storage for food, water, enzymes, and waste

21. Lysosomes
Digestion
(old organelles, food particles, viruses or bacteria)

22. Ever wondered how a tadpole gets rid of its tail and grows legs??
Lysosomes
Ever wondered how a tadpole gets rid of its tail and grows legs??
Lysosomes digest the cells in the tail, and these molecules are released to build different cells, like legs!

23. Energy Transformers Chloroplasts
Trap light for photosynthesis, plant cells only!

24. Powerhouse, makes energy Ex. Muscle cells have lots of these
Mitochondria
Powerhouse, makes energy
Ex. Muscle cells have lots of these

25. Support and Locomotion
Cytoskeleton
Framework of cell
microfilaments: Solid (ex. Cytoplasmic streaming)
microtubules: hollow (ex. Cilia, flagella)

26. Centrioles
Helps cell division of animal cells

27. Cilia
Flagella
Short hairs for movement
Long tail for movement

28. Organization
CellsTissuesOrgansOrgan systemsOrganisms

29. Review questions
What 2 cell parts are found in plant but not animal cells?
Which organelle is found in animal cells only?
