Structures and Functions Cells Structures and Functions

Cellular Organization: Cells work together to form tissues. Tissues work together to form organs. Organs work together to form organ systems. Organ Systems work together to form Organisms.

Cellular Organization: Video Time!!!

Types of cells… Unicellular – organisms that are made of only one cell. Multicellular - organisms that are made of more than one cell.

Types of cells… Video Time!!!

Types of cells… Prokaryotic – these are cells that DO NOT have a nucleus. BACTERIA!!! Eukaryotic – these are cells that DO have a nucleus. You!!!

Cell Structures and Functions: Organelles – tiny structures found inside of cells. Can you point out some cell organelles?

Cell Structures and Functions: Nucleus – directs all cell activities.

Cell Structures and Functions: Cell Membrane - protective outer membrane of a cell that allows only certain materials to pass into and out of a cell.

Cell Structures and Functions: Cytoplasm – gel-like material inside the cell membrane and outside the nucleus.

Cell Structures and Functions: Endoplasmic Reticulum - folded membrane that moves materials around in the cell (transportation system).

Cell Structures and Functions: Mitochondria - organelles that break down food and release energy. The Power House of the cell!

Cell Structures and Functions: Cell Wall – rigid structure made of cellulose that supports and protects the plant cell. Always found outside of the cell membrane.

Cell Structures and Functions: Chloroplast - organelles in plant cells that change light energy into chemical energy in the form of a sugar. PHOTOSYNTHESIS!!!

Cell Structures and Functions: Vacuoles - storage tanks for the cell (food, water, and waste).

RIBOSOME- MAKES PROTEINS OTHER CELL PARTS RIBOSOME- MAKES PROTEINS GOLGI BODY- Packages items to ship to other parts of the cell
