Intro to Cell Vocabulary

1. Intro to Cell Vocabulary Your names (groups of 2):

2. The Review Assignment: Using your notes and the internet- • fill in the following fields • answer the following questions • and find pictures using the internet. • Some frames have no fill-ins, just a little reading. • Change backgrounds!!!!!!

3. Cells • Cells are the basic unit of all living things…if it is alive it has cells. Some have 1 cell, they are called ________________. Some have many cells , they are called _______________.

4. What are the 3 parts to the cell theory? 1. 2. 3. What is the one exception (write and find a picture)________________________

5. Cell Differentiation • Differentiation is when cells GET A JOB. If they don’t have a job they are called “undifferentiated”. Another word for getting a job is specialization. I am a heart cell! I’m a Prison Cell!  I am a skin cell

6. Prokaryotic vs. Eukaryotic Cut and paste a picture of each off the internet. Label Prokaryotic and Eukaryotic. What is is the main difference between these two cells and give an example.

7. Cell Membrane • The cell membrane holds the cell together and allows nutrients in the cell, and wastes out. • The cell membrane is on the edge of a cell • The Cell Membrane is Semi-permeable, that means______________________

8. Cell Membrane Composition (what it’s made of) Search for a diagram of the cell membrane and put it in the presentation. Label the proteins, and lipid layers with arrows.

9. Would water go in or out of the cell? _____________ What is the movement of water across the cell membrane called? ________ Label the movement of water with an arrow. 30% NaCl 70% Water 10% NaCl 90% H20

10. Cytoplasm • Cytoplasm is the watery gel (Jello!) inside a cell….it’s goop! It holds the ORGANelles • Cell Metabolism happens in the cytoplasm. What is metabolism? _________________

11. Mitochondria • Mitochondria is an ORGANelle that releases energy from food. It is the _________ House of the cell. • Label O2 and Sugar going into the mitochondria, and CO2 and ATP coming out.

12. Nucleus • The nucleus controls the cell It contain DNA and a dark smaller organelle called the Nucleolus. The nucleolus makes _r_______________ which synthesis proteins from a________ acids. .

13. Chromosomes • Chromosomes are inside the nucleus and are made of genes (DNA) • Genes decide the cells traits and activities (heart cell, eye cell (color))

14. Nuclear Membrane • The nuclear membrane allows substances to pass in and out of the nucleus • It surrounds the nucleus (the brain)

15. Vacuoles • Vacuoles are spaces in the cytoplasm (gel) where food and chemicals are stored. Copy and move the arrows to label ALL of the vacuoles in the cells below.

16. Cell Wall • Cell Walls are only in plant cells. They are made of _________ose. • They make the cell strong and rigid • They are like a turtle’s shell (but only plants have them…that’s why grass stands straight up!) • Drag the arrow and place on the cell wall. • Is the Cell Wall inside or outside of the cell membrane?__________

17. Chloroplasts • Chloroplasts are only in plant cells (and are usually around the outside edge) • They contain the pigment (color) __________, which helps to synthesize energy/food from sunlight • What gas do plantsrelease as a result of photosynthesis? ________________

18. What’s the Difference? • So what are two things that Plant cells have that animal cells don’t? What do they have in common???? Insert text boxes…

19. Label as many parts in this plant cell diagram as you can

20. Label as many parts in this animal cell diagram as you can
