Understand the structure and function of the parts of a typical eukaryotic cell.

ANSWER: best to see notes

  • plasma membrane - acts as a selectively permeable membrane
  • cell wall - ridged structure located outside plasma membrane that provides additional support and protection, plant cell only
  • nucleus - contains directions to make proteins and therefore controls the activity of the organelles
  • chromatin (or the strands of genetic material, DNA) - contains the master set of directions for making proteins
  • nucleolus - makes ribosomes
  • ribosomes - sites where the cell assembles enzymes and other proteins according to DNA
  • cytoplasm - clear, gelatinous fluid inside a cell
  • endoplasmic reticulum - site of cellular chemical reactions
  • Golgi apparatus - a flattened system of tubular membranes that modifies the proteins, sorts proteins into packages to be sent to the appropriate destination
  • vacuoles - are for temporary storage of materials
  • lysosomes - contain digestive enzymes, they digest excess or worn out organelles, food particles, and engulf viruses or bacteria
  • chloroplasts - capture light energy and produce food to store for a later time
  • chlorophyll - pigment that traps light energy and gives leaves and stems their green color.
  • mitochondria - transform energy for the cell
  • cytoskeleton - support structure within the cytoplasm
