1. Warm Up
____ 1. Provides energy for the cell by breaking down glucose molecules.
____ 2. Converts light energy to chemical energy for the plant cell through photosynthesis.
____ 3. This organelle controls all cell activities.
____ 4. Is selectively permeable.
 ____ 5. A gelatin-like substance that is the site of many chemical reactions in the cell.

2. Help Session
a collection of tissues that carry out specialized function of the body
a group of organs that work together to perform body functions
the arrangement of parts in an organism
a rigid structure that surrounds the cell membrane and provides support to the cell
a group of similar cells that perform a common function
an organism that consists of a single cell that does not have a nucleus

3. Help Session
one of the small bodies in a cell’s cytoplasm that contains the cell’s DNA and that has a role in processes such as growth, metabolism, and reproduction
cell organelle composed of RNA and protein; the site of protein synthesis
a system of membranes that is found in a cell’s cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids
in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration
the smallest functional and structural unit of all living organisms; usually consists of a nucleus, cytoplasm, and a membrane

4. Help Session a cell organelle that contains digestive enzymes
cell organelle that helps make and package materials to be transported out of the cell
a small cavity or sac that contains material in a eukaryotic cell
the special, normal, or proper activity of an organ or part
a phospholipid layer that covers a cell’s surface; acts as a barrier between the inside of a cell and the cell’s environments
an organism made up of cells that have a nucleus enclosed by a membrane

5. The Cell: The Basic Unit of Life

6. The Cell The Cell has many parts.
Each part has a specific job and plays an important part in the life of a cell.

8. Cell Membrane Structure: protective layer that surrounds the cell.
Composed of lipids and phospholipids.
Function: controls interactions between the environment and the inside of the cell.

11. Cytoplasm
Structure: Gelatin like substance inside cell, constantly flowing.
Function:
a) keeps the cell moist.
b) allows for chemical reactions to take place.

12. Cytoskeleton Structure: framework made up of thin hollow tubes.
Function: Helps the cell maintain it’s shape

13. Nucleus The brain of the cell Structure: has it’s own membrane.
Functions:
a) directs all cell activity
b) contains the hereditary material (DNA)

15. Mitochondria The POWER HOUSE of the cell!!!!!
Function: breaks down nutrients to make energy for the cell.
ATP is the energy source.
*Why would muscle cells in your legs have more mitochondria than muscles in your abdomen?

17. Ribosomes Made in the nucleolus and sent out to the cytoplasm.
Structure:
-Not membrane bound
-Either float freely in the cytoplasm or are connected to the endoplasmic reticulum.
Functions:
-Produces protein using the information provided by the DNA.

18. Ribosomes

19. Endoplasmic Reticulum
Made up of folded membranes
Structure: either be rough or smooth
-Rough: has ribosomes
-Smooth: no ribosomes
Functions:
-Acts as the processing center for proteins and other substances.
-A system of highways to send things to different places.

21. Golgi Bodies Golgi Apparatus/Golgi Complex
Structure:
-Stacked membranes, acts as the mail center.
Functions:
-Sort out proteins and other substances in vesicles (packages) to go to their appropriate places (other parts of the cell, organelles, or out of the cell).

23. Vacuoles
Vacuoles: temporary storage for any excess cell material.

25. Lysosomes Function: -Breaks down and recycles unused substances
-Also kills the cell (Lysis) when the cell is no longer functional.

26. Extra Plant Structures
Plants are unique organisms and their cells have two added organelles.
Cell Wall
-Tough, rigid, outer coverings made of CELLULOSE (a carbohydrate)
Function:
-Protection
-Support and shape for the plant

28. Chloroplasts Green organelles that contain chlorophyll Function:
Chlorophyll captures light and uses it to make energy (photosynthesis).

29. Different Types of Cells

30. Mitochondrion- power packed Cytoplasm- oooey, gooey
Nucleus- I’m the boss
Mitochondrion- power packed
Cytoplasm- oooey, gooey
Membrane- coming or going
Vacuole- hold on layaway
Golgi Bodies- packed –n- ready
Lysosomes- clean up the junk
Ribosomes- one order o’ proteins
ER- on the road again
Cytoskeleton- keep’n the shape
Chloroplast- green food machine
Cell Wall- rough –n- tough
