Cell Organelles And all the wonderful things they do!

There are many parts to the cell. Each part has a specific job and plays an important part in the life of a cell. 1) Cell Membrane -protective layer that surrounds the cell -Function: controls interactions between the environment and the inside of the cell

2) Cytoplasm -Gelatin like substance inside cell, constantly flowing -Function: a) keeps the cell moist b) allows for chemical reactions to take place 3) Cytoskeleton -framework made up of thin hollow tubes. Helps the cell maintain it’s shape

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

5) Mitochondria -powerhouse of the cell -Function: breaks down nutrients to make energy for the cell *Why would muscle cells in your legs have more mitochondria than muscles in your abdomen?

Ribosomes - Made in the nucleolus and sent out to the cytoplasm -Not membrane bound -Either float freely in the cytoplasm or are connected to the endoplasmic reticulum Functions: 6) l Produces protein using the information provided by the DNA

Ribosomes

Endoplasmic Reticulum Made up of folded membranes 2) Can either be rough or smooth 1) 1) 2) Rough: has ribosomes Smooth: no ribosomes Functions: -In general, the ER acts as the processing center for proteins and other substances -A system of highways to send things to different places

7) Golgi Bodies -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) 8) Vacuoles: temporary storage for any excess cell material

Golgi Bodies

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

Extra Plant Structures Plants are unique organisms and their cells have two added organelles 1) Cell Wall -Tough, rigid, outer coverings made of CELLULOSE (a carbohydrate) -Function: Ø • Protection • Support and shape for the plant

2) Chlorplasts l l Green organelles that contain chlorophyll Function: • Chlorophyll captures light and uses it to make energy (photosynthesis)

Different Types of Cells

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