cell organelles

• What are Cell Organelles?

  are small structures in the cytoplasm that carry out functions necessary to maintain homeostasis in the cell.
• Lysosomes

  Function: breakdown material brought into the cell. can make new lysosomes from old parts

  Structure and Location: medium circles in cell

  ONLY IN animal cells
• Cytoplasm

  Function: supports organelles inside the cell

  Structure and Location: clear jelly/fluid around the organelles
• Mitochondria

  Function: produces the energy (ATP) to run the cell

  Structure and Location: bean shaped and scattered throughout the cytoplasm
• Golgi body

  Function: receives proteins from ER modifies them and packages proteins into vesicles to be transported inside cell or to the outside

  Structure and Location: stack of membrane bound, flattened sacs
• Smooth ER

  Function: produces lipids and hormones

  Structure and Location: near the nucleus does not contain ribosomes

  ALSO KNOWN AS smooth endoplasmic reticulum
• Rough ER

  Function: isolation, modification transport of proteins and other substances

  Structure and Location: next to the nucleus and has a rough appearance due to ribosomes

  ALSO KNOWN AS rough endoplasmic reticulum
• Cell membrane

  Function: confines cell contents and regulates entry and exit of materials

  Structure and Location: phospholipid bilayer
• Ribosomes

  Function: produces protein

  Structure and Location: little round dots on the rough ER or in the cytoplasm
• Nucleus / Cell brain

  Function: houses and protects the cells genetic information in the form of chromosomes (DNA and proteins)

  Structure and Location: circular shaped structure in the cell
• Chloroplast

  Function: captures energy from the sun and uses it to produce food for plant cells

  Structure and Location: oval shaped structure with specialised internal structure

  ONLY IN plant cells
• Cell wall

  Function: protection, structural support

  Structure and Location: made of tough fibrous material called cellulose

  ONLY IN plant cell
• Vacuole

  Function: storage area that may contain air, water, wastes and food particles

  Structure and Location: central, large sac
• Flagella

  Function: found in single cell organisms for movement though liquid

  Structure and Location: long slender "whip" like extrusion

  ONLY IN animal cells
