1. 2.3 Investigating Cell Specialization

2. Blood Cells Red Blood Cells:
Bowl shaped and flexible to move through blood vessels (veins and arteries)
Deliver oxygen to the body and remove carbon dioxide
White Blood Cells:
Irregular shape with pseudopodia that help trap invaders
Protect body from invaders

3. Compact Bone Cells Dense and tightly grouped together
Provide support for itself and organism

4. Root Cells Cells are long a tubular Absorb water Anchor the plant
Vascular tissue: xylem and phloem in the middle of the specimen
Xylem moves water and minerals
Phloem moves simple sugars

5. Skeletal Muscle Cells Long and look like fibers bundled together
Pull on tendons attached to bones
Aid in voluntary movement: walking, bending etc.

6. Adipose Cells Large and round cells Make and store fat
Provide insulation to prevent heat loss
Provide protection and support around organs
Store energy

7. Leaf Cells Guard cells regulate stoma
Stoma exchange oxygen and carbon dioxide
Stoma let out water vapor for transpiration
Open during the day
Closed at night

8. Nerve Cells Elongated with branching fibers
Send and receive electrical and chemical messages around body
Dendrites receive signals
Axons send signals to other cells

9. Plant Epidermal Cells Make up outer layer of plant’s body
Act as a boundary
Absorb water and minerals
Protect against transpiration
Regular gas exchange for photosynthesis and cellular respiration
