1 Cells: Building Blocks of Life
1st Quarter

2 A cell that contains a nucleus.
Eukaryotic cell- A cell that contains a nucleus.

3 Two types of eukaryotic cells.
Animal cell Plant cell

4 Prokaryotic- A cell that does not have a nucleus.

5

6 Cell membrane- the layer through which substances pass in and out of the cell. 

7 Cell membrane

8 Cell Wall- The outermost layer of plants cells.

9 Plant cell wall

10 Nucleus – found in eukaryotic cells; contains DNA. The control center for the cell.

11 The job of a nucleus is to be the control center of the cell
The job of a nucleus is to be the control center of the cell. The nucleus in a human cell has forty-six chromosomes. This stores the instruction of the cell's activity. The nucleus is like a vault. It contains the cell's DNA.

12

13

14 DNA (deoxyribonucleic acid) - Heredity material that controls all the activities of a cell.

15

16 Chromosomes-directs the activities of a cell and passes on the traits of a cell to new cells.

17

18 Cytoplasm- fluid surrounding a cell’s organelles.

19 Lysosomes- digests food particles, wastes & foreign invaders.

20

21 Vacuoles- Stores water and other materials.

22 Mitochondria- breaks down food molecules.

23 Chloroplasts-Makes food using the energy of sunlight
Chloroplasts-Makes food using the energy of sunlight. (This process is called Photosynthesis)

24

25 Endoplasmic Reticulum- (ER)
packages up proteins for release from the cell.

26

27 Ribosomes- Makes proteins.

28 Golgi Body Complex- Processes and transports materials out of the cell.

29 Homeostasis Maintaining stable conditions.
Ex: sweating when running so you don’t overheat

30 Diffusion- which molecules of a substance move from areas of higher concentration to areas of lower concentration.

31 Here’s an example.

32 Let’s test this out Let’s perform a few experiments to find out how it works. I have a air freshner that I will spray at the front of the room. The person at the back of the room will tell me when he/she smells the scent.

33 Endocytosis - cell takes in large particles by engulfing them.

34

35 Exocytosis - cell gets rid of particles, opposite of endocytosis

36

37

38 The End.
