1. Cell Basics and Plant Cells

2. Cell – the smallest unit that can perform all life processes
Cell Theory
All living things are made up of one or more cells
Cells are the basic units of structure and function in organisms
All cells arise from existing cells

3. The Purpose of the cell
The purpose of a cell is to carry out the its function with is found in the Deoxyribonucleic acid (DNA)
In order for the cell to carry out the functions in the DNA it must convert it to a protein.
So the purpose of a cell is to create Proteins.

5. Two types of Cells
Prokaryotic Cells – bacteria and other single celled organisms
a. Has only a single loop of DNA (that is not membrane bound), ribosomes and enzymes that are in cytoplasm
b. Have a cell wall around the cell membrane, some also have a capsule that allows them to cling to things

7. Cilia Movement hairs, they are small and generally surround the cell.
Found mostly on prokaryotes.

8. Two types of Cells
2. Eukaryotic Cells – are in organisms that are made up of one or more cells
a. They are more complex so they can carry out more specialized functions than prokaryotic cells
b. Two different types: plant and animal cells

9. One of the top 5 coolest biology videos ever… for REAL!

10. Plant Cells

11. Cell Membrane – Is responsible for the controlled entry and exit of molecules, “the gate keeper” *One of the most important parts of the cell, later this unit we will go more in depth into cell membranes important role! SILVER

13. Cell Wall – provides and maintains the shape of cells and serves as a protective barrier TAN

15. Nucleus – the cell’s internal compartment for the DNA Contains chromosomes – the structure of DNA that carries the genes and functions of the cell PURPLE

16. Nucleolus The Nucleolus is the inner part of the cell’s nucleus
Creates ribosomes

17. Chromatin
Collection of DNA in a cell

19. Cytoplasm – controls cell metabolism including signal pathways and receptors, “cell jello” YELLOW

21. Ribosomes – serves as a site to make proteins, protein synthesis occurs here “protein factory” BLACK DOTS

23. Organelle – a structure that carries out a specific activities inside the cell
Chloroplast – contains the plant cell’s chlorophyll, produces food by turning sunlight into food (photosynthesis and cell respiration… remember these?) “food factory”
GREEN

25. Cytoskeleton – helps maintain the cell shape, motility and internal movement “framework”
DON’T NEED TO COLOR

26. Let’s look at the animal cell next…
Then let’s talk about the differences!

28. Endoplasmic Reticulum –. Rough ER – helps make proteins with the
Endoplasmic Reticulum – Rough ER – helps make proteins with the help of ribosomes Smooth ER – helps make lipid and membrane proteins
BLUE

30. Golgi Body Apparatus – important for packaging macromolecules for transport about the cell “packagers”
PINK

31. Vesicles Temporary storage of food Transports materials in a cell
Created by The Golgi Apparatus

33. Vacuole –helps with digestion in the cell and is where all the cellular waste gets released/stored “outhouse”
CLEAR/WHITE

35. Mitochondria – provide the energy a cell needs “powerhouse of the cell” “mighty mitochondria”
ORANGE

37. Lysomome
Digests worn out cell parts, bits of food, and virus’, and bacteria.

38. microtubules
Hollow tubes that provide support
