1. Cells

2. Objectives
Identify parts of cell and understand their functions with 80% accuracy.
Define key terms for the cell with 100% accuracy.

3. Why? Why are cells important? Why should we know the parts of a cell?
Why should we know what a cell looks like?

4. What? What is the definition of cell?
What are the different parts of a cell?
What are the functions of each part of the cell?
What does a cell look like?

5. Terms Cell: The Basic unit of life
Chromosome: A strand of genetic material that contains genetic code
Females: XX
Males: XY
Gene: A unit of inheritance composed of DNA
DNA: (deoxyribonucleic acid) is a nucleic acid containing the genetic instructions used in development and functioning of a cell

6. DNA

7. Animal Cell

8. Chromosomes
Structures that are physical carriers of genes, made of DNA, are located in cell nucleus

9. Cell

10. Cell Membrane-
Delicate structure that surrounds the cell

11. Cytoplasm
Cell fluid containing all cell structures

12. Nucleus
Control center of a cell, contains most of the DNA

13. Mitochondria
Energy producing structures in the cell cytoplasm, contain some DNA

14. Ribosome
Site where new proteins are produced, result of genetic expression

15. Rough endoplasmic reticulum
Synthesize and packages proteins

16. Smooth endoplasmic reticulum
Include lipid synthesis, carbohydrate metabolism, calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins.

17. Golgi apparatus
Where molecules are packaged for delivery to other cell components

18. Centriole
Organize mitotic apparatus which consists of asters and spindle fibers which help in division of chromosomes

19. Lysosome
Destroying any foreign body and unwanted cell organelles that may be present in the cytoplasm
