organelles

• Nucleus is the control center (controls cell division) of the cell and contains the genetic material in the form of chromosomes
• Cytoplasm is a jelly-like substance that fills the cell and contains the cell's organelles
• Cell membrane is a selectively permeable barrier that controls the movement of substances into and out of the cell.

  • lets nutrients in, and waste out
• Cell wall is a rigid structure that surrounds the cell, keeping its shape and giving it support
• Ribosomes are the site of protein synthesis

  • Not membrane bound
• Mitochondria are the powerhouse of the cell and the site of aerobic respiration

  • cells with high rates of metabolism (i.e they move a lot) have many mitochondria
• Chloroplasts are the site of photosynthesis and contain chlorophyll.
• Vacuole is a membrane bound space containing cell sap and stores water, food, pigments, and wastes
