2. Organization and Development
Cells
Cells are the smallest living part of any organism. All living things are made up of cells. They are the “building blocks” of life.

3. What does a cell do? Cells take in food Cells turn food into energy
Cells get rid of waste

4. Cellular Respiration
Most cells get their energy from cellular respiration
Cellular respiration is when a cell takes in oxygen and food (such as sugar) and makes energy
Carbon dioxide and water are made during cellular respiration

5. Animal Cell Parts Cell Membrane This surrounds the cell
It allows materials such as sugar, water, and oxygen to enter the cell
It allows waste to exit the cell

6. Animal Cell Parts Nucleus This is the control center of the cell
Nucleus contains Chromosomes and DNA

7. Animal Cell Parts
Mitochondria
Mitochondria produce energy in the cell

8. Animal Cell Parts
Vacuole
The vacuole provides storage for the cell

9. Animal Cell Parts Cytoplasm
Cytoplasm is the material between the cell membrane and the nucleus. It holds the smaller parts of a cell.

10. Plant Cells
Discovery Science Plant Cells

11. PLANT CELLS
Plants also have a cell wall

12. Plant Cells
The cell wall gives extra support and protection to the plant (similar to an exoskeleton).

13. Plant Cells
Plant cells also have Chloroplasts

14. Plant Cells
Chloroplasts use sunlight to turn water and carbon dioxide into oxygen and sugar

15. Plant Cells
Chloroplasts give plants a green color

16. Types of Cells
There are about 200 kinds of cells in the human body.

17. Types of Cells
Branching Cells – Nerve cells are branching cells. The length helps send signals quickly.

18. Types of Cells
Flat Cells- Human skin cells are flat cells. They layer to provide flexibility and protection.

19. Types of Cells
Round Cells – Red blood cells are round. The shape lets them maximize surface area to carry more oxygen.

21. Cells to Tissue
Tissue is a group of cells working together to do the same job.

22. Cells to Tissue There are 4 types of tissue in the human body:
Muscle Tissue – Moves your body
Can be voluntary (you can control-skeletal) or Involuntary (you can’t control-heart)

23. Cells to Tissue Nervous Tissue – Send signals throughout your body
Nervous tissue can be found in the brain

24. Cells to Tissue
Epithelial Tissue – Covers the body and line the inside of the body
Skin is an epithelial tissue

25. Cells to Tissue Connective Tissue – Helps support and protect the body
Bone and fat are types of connective tissue

26. Tissue to Organ
Different types of tissue join together to form an organ.

27. Tissue to Organ
Skin is the largest human organ

28. Tissue to Organ
Heart is another example of an organ

29. Tissue to Organ
The stomach is another example of an organ

30. Organs to Organ Systems
Organs join together to form an Organ System. Organ Systems carry out major body functions.

31. Organs to Organ Systems
There are 11 organ systems in the human body

32. Organ Systems
Circulatory System
transports blood throughout the body

33. Organ Systems Digestive System
breaks down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair

34. Organ Systems Endocrine System glands that produce hormones
hormones are chemicals that control body functions, such as metabolism, growth, and development

35. Organ Systems
Excretory System
Eliminates body’s waste

36. Organ Systems Immune/Lymphatic System
body's defense system against infections and diseases
distributes fluids and nutrients in the body and drains excess fluids and protein so that tissues do not swell.

37. Organ Systems Integumentary System
Protects the body (skin, hair, nails)

38. Organ Systems Muscular System
works with the skeletal system to control movement of the body

39. Organ Systems Nervous System
sends, receives, and processes nerve impulses throughout the body
nerve impulses tell your muscles and organs what to do

40. Organ Systems Reproductive System
Allows living things to produce offspring

41. Organ Systems Respiratory System
brings air into the body and removes carbon dioxide

42. Organ Systems Skeletal System major functions of the skeletal system:
keep shape and support of your body
enable you to move
protect your internal organs
produce blood cells
store materials.
