Cell Organelles Review Types of Cells l Prokaryotic

Cell Organelles

*Review* Types of Cells l Prokaryotic l Eukaryotic • Bacteria • Archaea • Plants • Animals • Fungi

*Review* Common Parts in All Cells l l l Cell Membrane- Protective layer that covers the cell’s surface Cytoplasm- The fluid found inside a cell Organelles- Structures that perform specialized functions within a cell

Other Organelles in a Cell l l Nucleus, Ribosomes, Endoplasmic Reticulum (ER), Mitochondria, Golgi Complex, Vesicles, Lysosomes Plants also contain Cell Walls, Vacuoles, and Chloroplasts

Nucleus l l l Found only in Eukaryotic Cells Contains the cell’s DNA Control center of the cell

Ribosomes l l l Organelle that makes proteins Smallest of all organelles More ribosomes than any other organelles

Endoplasmic Reticulum (ER) l l System of folded membranes Part of the internal delivery system of the cell Contains many tubes and passageways Substances move through the ER to different places in the cell

“ER”- People go through the ER to get to other places in the hospital!

Mitochondria l l l Powerhouse of the cell Organelle in which sugar is broken down to produce energy Cell uses the energy to do work

The “Mighty” Mitochondria! – Powerhouse! l Cannot do work without energy!

Golgi Complex l l Organelle that helps make and package materials to be transported out of the cell or to other parts of the cell Packaged material is stored in a vesicle

Golgi Compl-EX…. Fed-EX… Package and transport materials!

Vesicles l l l A small cavity or sack that contains materials Created in the Golgi Complex Can move out of the cell or to other parts within the cell

Vesicles- created in Golgi Complex…contain materials and transports them where they need to go!

Lysosomes l l l Cell organelles that contain digestive enzymes Digests food particles, gets rid of waste material, and protects the cell from foreign invaders Mainly in animal cells

Lysosomes- get rid of waste, protects cell from foreign invaders

Cell Wall – Plant Cell Only! l l A rigid structure that surrounds the cell membrane Gives support to the cell

Vacuole- Plant Cell Only! l l l A type of vesicle found in plant cells Aid in digestion within the cell Stores water and other liquids which help to support the cell

Vacuole…Vacuums store objects too

Chloroplast- Plant Cell Only! l l l Organelle found in plant cells in which photosynthesis takes place Uses the energy of sunlight to make food Are green in color

Animal Cell
