Cells and Heredity Chapter 1 Lesson 2

2. How do the Parts of a Cell Work: Cell Wall and Cell Membrane
Each cell structure has a different function within a cell.
Cell Wall
not present in animal cells
Support and protection
Cell membrane
all cells
controls which substances pass into and out of the cell

3. How do the Parts of a Cell Work: Nucleus
control center of the cell
Directs cell functions
Chromatin
Long uncoiled strands of DNA
Nucleolus
Inside the nucleus
Makes ribosomes

Bellringer
Look at the pictures on pgs. 14 and 15. These are electron micrographs (made with electron microscopes). Notice that all of the parts of the cell pictured have outer membranes.
What function does the outer membrane serve? Write your answer in sentence form in the blank space on pg. 15 above the animal cell sketch.

5. How do the Parts of a Cell Work: Organelles inthe Cytoplasm
Tiny cell structures that carry out specific functions within the cell
Ribosomes
Produce proteins
Cytoplasm
gel-like fluid that holds the organelles

6. Organelles in the Cytoplasm
Mitochondria
Convert energy stored in food to cellular energy (make energy)
Endoplasmic Reticulum
Rough
Transports proteins that are made by the ribosomes
Smooth
Make substances and detoxifies

7. Bellringer Identify each of the following organelles
Powerhouse of the cell makes energy _______
Transport system, transports proteins _______
Holds the organelles ____________
Controls what substances enter and exit_____
Produces proteins __________
Produces ribosomes _________

8. Organelles in the Cytoplasm
Golgi apparatus
Packages and distributes cell products
Vacuole
Stores water food or other products
Chloroplast
Captures energy from sun and changes it to a form of food
Lysosomes
Digest food particles, old cell parts

9. How do Cells Work Together
In multicellular organisms, cells are organized.
Tissue
group of similar cells that work together to perform a specific function
Organ
different tissues that function together
Organ system
group of organs that work together to perform a major function
