cell biology hsa review

1. Cell Biology HSA Review
Directions:
• Pick up an iPad or Log on to a
computer
• You may work with a partner (no
more than 2 people together)
• Go to website
• Use website to complete the review
• You have 45min to complete 

2. Organelles
 Nucleus
◦ Controls cell activities
 Mitochondria:
◦ Makes energy!
◦ Cell Respiration
 Chloroplast:
◦ Makes food for plants
◦ Photosynthesis

3. Organelles
 Ribosome
◦ Makes protein
 Cilia/Flagella
◦ Both help cell move
◦ Cilia= hair-like Flagella= tail
 Cell Membrane:
◦ Controls what enters/leaves the cell

4. Nucleus
Cell Membrane…
What’s it made
of?
Ribosomes
Mitochondria
Chloroplast
Cell Wall…
What’s it made of?

5. Transport of Materials
 Cell Membrane
◦ Controls what enters/leaves the cell
 Circulatory System
◦ Carries oxygen, nutrients to cells
◦ BLOOD!
 Vascular Tissues
◦ Carries water, nutrients to plant cells

6. Body Systems
 Circulatory System
◦ Carries oxygen, nutrients to cells
◦ BLOOD!
 Reproductive System
◦ Makes eggs/sperm (gametes) to pass on
genes to next generation
 Excretory System
◦ Removes bulk waste

7. Body Systems
 Nervous System
◦ Controls everything, Controls movement
 Endocrine System
◦ Hormones
◦ “chemicals that regulate/act at different
sites in the body”

8. Body Systems
 Skeletal System
◦ Attaches to muscles for movement
◦ Bones
 Muscular System
◦ Attaches to bones for movement
◦ Muscles

9. Body Systems
 Digestive System
◦ Breaks down food and nutrients
 Respiratory System
◦ Breathing
◦ Takes in Oxygen, releases CO2

10. Asexual Reproduction
 Mitosis
◦ Cell division in body cells
◦ To make more IDENTICAL cells
 Binary Fission
◦ Division IN BACTERIA
 Cells After Asexual Reproduction
◦ IDENTICAL to original cell
◦ Cloning

11. Homeostasis
 Definition
◦ Maintaining stable internal conditions
◦ Keeping everything in the body “normal”
 Examples:
◦ Body temperature
◦ Blood sugar
◦ Blood pressure

12. Diffusion/Osmosis
 Selectively Permeable
◦ Only allows certain things to move through
◦ The cell membrane is selectively permeable
 Diffusion
◦ Molecules move from high to low
concentration
◦ No energy required
 Osmosis
◦ WATER moves from high to low
concentration
◦ No energy required
