Cell Organelles

What you need to know

slide2

An organelle is a membrane-bound structure that carries out specific activities for the cell.A “mini” organ

you will need to know the following organelles and their function
You will need to know the following organelles and their function:
  • Cell Membrane
  • Nucleus
  • Cytoplasm
  • Mitochondria
  • Ribosomes
  • Smooth Endoplasmic Reticulum
  • Rough Endoplasmic Reticulum
  • Cell Wall
  • Chloroplast
  • Vacuole
  • Lysosome
cell membrane
Cell Membrane
  • Every cell is enclosed by a cell membrane. It controls the passage of materials in and out of the cell.
nucleus
Nucleus
  • The control center of the cell.
  • Surrounded by the Nuclear Membrane which controls the passage of materials in and out of the nucleus
  • Contains Chromosomes which hold the genetic information for the cell (DNA)
cytoplasm not an organelle but important
Cytoplasm(not an organelle - but important)
  • All organelles live and float

around in the cytoplasm.

mitochondria
Mitochondria
  • This organelle processes energy for a cell. It makes ATP.
  • ATP = energy
  • Involved in cellular respiration
  • The powerhouse of the cell
ribosomes
Ribosomes
  • Synthesizes proteins
  • Present in the cytoplasm
  • Present with Rough ER
endoplasmic reticulum
Endoplasmic Reticulum
  • Transports materials throughout the cell

Rough ER

  • Covered with ribosomes, making it rough
  • Produces proteins
  • Transports materials throughout the cell

Smooth ER

  • Produces lipids
  • No ribosomes
vacuole
Vacuole
  • Stores enzymes and aids in digestion
  • Plants have a large central vacuole- larger than vacuoles in animal cells
lysosome common in animal cells rare in plant cells
Lysosome(Common in Animal Cells; Rare in Plant Cells)
  • Breaks down materials for digestion
  • Contains special enzymes for digestion in the cell
cell wall plant cell only
Cell Wall (Plant Cell Only)
  • Rigid and strong wall
  • Protects and maintains the shape of the cell
chloroplast plant cell only
Chloroplast(Plant Cell Only)
  • Photosynthesis takes place here
  • Contains chlorophyll
  • Makes plants green
  • Uses light energy to make ATP & sugars
