5. Levels Of Organization Cells are the basic unit of Structure and Function!

6. Cell Structure and Functions

7. Cell Theory There are three parts to the cell theory
1. All living things are made of one or
more cells
2. cells are the basic units of structure
and function in organisms.
3. All Cells arise from pre-existing cells

9. Cell Organelles What are organelles?
internal compartments that carry out specific cell functions
How are organelles beneficial to a cell?
They allow the cell to grow larger and become more specialized

11. Nucleus: control center; houses DNA; directs activities of the cell
Nucleolus: producing ribosomes
Nuclear envelope: encloses the nucleus and its contents
Nuclear pore: pore in nucleus; can allow substances (RNA) to leave

12. Mitochondria Powerhouse of the cell Energy production for cells (ATP)
Sites of aerobic respiration
“mitochondria makes me mighty”

13. Smooth endoplasmic reticulum
Synthesizes steroids
Detoxifies poisons (alcohol)
Transports substances
Regulates calcium levels for muscle contraction

14. Transports proteins

15. Ribosomes
Make proteins

17. Golgi Apparatus membrane-bound structure
organelle modifies molecules and packages them into small membrane bound sacs called vesicles

18. Vesicle
Membrane-sac that transports materials

21. Lysosomes digests waste materials and food within the cell
breaks down molecules into their base components with strong digestive enzymes

22. How do plant cells differ from animal cells?

23. Plant Cell Plant cells have different structures Contains: Cell wall
Great wall of China
Chloroplast
Site of photosynthesis
Vacuole (large central, takes up most part of cell)

24. Cell membrane
Regulates substances in and out of the cell.

25. Cell wall
Protection

26. Cytoplasm
Fluid portion of the cell

27. Assist with cell division : helps to move chromosomes
centrioles
Assist with cell division : helps to move chromosomes

28. Hereditary informer
Material consisting of DNA and proteins only visible during cell division.

29. Different levels of DNA condensation. (1) DNA strand
Different levels of DNA condensation. (1) DNA strand. (2) Chromatin strand (DNA with histones). (3) Chromatin during interphase with centromere. (4) Condensed chromatin during prophase. (Two copies of the DNA molecule are now present) (5) Chromosome during metaphase.

30. Part of cytoskeleton
Assist in cell division and provide internal support
Can combine with other proteins to form complex structures like cilia and flagella

32. Cilia
Fine, hair-like projections on surfaces of cells

33. Flagella
Cellular movement

34. peroxisome
