Cell Organelles and their Functions *Double hamburger and glue your homework to the top right of page 10 in your journal

Cells Cells are the basic unit of all living things. IF IT IS ALIVE, IT HAS CELLS! Cell Theory: – All organisms are made up of one or more cells – The cell is the basic unit of all organisms – all cells come from cells

Two Types of Cells PROKARYOTE EUKARYOTE

A Cell Membrane B Cytoplasm C Mitochondria D Nucleus E Endoplasmic Reticulum F Golgi Apparatus G Ribosomes H Vacuoles I Cell Walls J Flagella

Cell Membrane The cell membrane holds the cell together and allows nutrients into the cell. A

Cytoplasm the watery gel inside a cell. It holds the ORGANelles. B

Mitochondria ORGANelle that produces energy for the cell. C

Nucleus The nucleus controls the cell. It contains the cell’s DNA. D

Endoplasmic Reticulum A network of membranes throughout the cytoplasm of the cell. It helps to move materials around the cell. E

Golgi apparatus Responsible for sorting, packaging, and shipping the proteins produced in the ER. F

Ribosomes help in the synthesis of proteins. Some ribosomes are found in the cytoplasm, but most are attached to the endoplasmic reticulum. G

Vacuoles Vacuoles are spaces in the cytoplasm where food and chemicals are stored H

Cell Wall Cell Walls are NEVER in animal cells They make the cell strong and rigid I

Flagella Can be found in both prokaryotic and eukaryotic cells Used for movement J

Card Sort with table After I check that they are correct, go back and add your analogy word to each organelle listed Example: nucleus = person in charge
