1 The basic unit of structure for all living things!

2 Theory – well tested hypothesis. 1.All living things are made up of cells. 2.Cells are the basic unit of structure and function in living things. 3.New cells come from existing cells.

3 Prokaryotic Cell – cells that lack a membrane bound nucleus. Example: Bacteria

4 Eukaryotic Cell – a cell that contains a membrane bound nucleus and many specialized structures called organelles “tiny organs”

5 Single Celled – organisms made up of 1 cell (ex. amoeba, paramecium, euglena) Multicellular – organisms made up of many independent cells working together (plants and animals)

6

7

8 Plant & Animal Cells

9 Function – protection & controls what enters and leaves cell. Structure – double layered Phospholipid membrane

10

11

12 Function – holds all organelles and nutrients. Structure – semi-solid fluid (water, proteins, various nutrients)

13 Function – Protects the DNA Structure – phospholipid membrane (nuclear envelop) & internal fluid called nucleoplasm.

14 Function – constructs lipids and special proteins (enzymes) for detoxification Structure – folded phospholipid membrane

15 Function – modifies proteins and packages them to be shipped out. Structure – phospholipid membrane found in stacks.

16 Function – power house of cell – place where food is broken down and turned into energy. Structure – phospholipid membrane

17 Plant Cells Only Function – makes food (sugars) Structure – phospholipid membrane Function – protection and support Structure – cellulose (carbs.)

18 Groups of similar cells working together.

19 1. Epithelial Tissue – covers interior and exterior body surfaces. Skin

20 2. Connective Tissue – provides support for the body and connects all of its parts.

21 3. Nervous Tissue – transmit nerve impulses throughout the body.

22 4. Muscle Tissue – enable the body to move.

23 Groups of similar tissues working together. Groups of similar organs working together.

24

25 Function – relays messages from one part of the body to another Structure – brain, spinal cord & peripheral nerves

26 Function – serves as a barrier against infection Structure – skin

27 Function – brings oxygen in and carbon dioxide out. Structure – nose, trachea, pharynx, bronchi and lungs

28 Function – converts foods into molecules that can be used by body. Structure – mouth, esophagus, stomach, and intestines

29 Function – Eliminates waste products Structure – skin, lungs, kidneys urinary tract

30 Function – supports body,allows movement and produces blood cells. Structure – Bones

31 Function – allows body to move. Structure – smooth muscle, cardiac muscle & skeletal muscle.

32 Function – brings oxygen, nutrients, and chemical messengers to cells. Structure – heart and blood

33 Function – regulates & controls the bodies functions Structure – glands

34 Function – produces sperm & egg cells. Structure – testes & penis; ovaries, fallopian tubes, uterus and vagina.

35 Function – protects the body from disease. Structure – white blood cells and lymph nodes
