What You Need to Know...

  • You need to know the general structures of plant and animal cells and how plant and animal cells are alike and different.
  • You need to know the general structures of prokaryotic and eukaryotic cells and how they are alike and different. 
  • You need to know how the structure relates to the function for the components of plant or animals cells. Structures you need to know are the cell wall, cell membrane, cytoplasm, plasmids, ribosomes, flagella, nucleus, nuclear envelope, nucleolus, chromatin, ribosomes, endoplasmic reticulum, microtubules, microfilaments, vacuoles, mitochondria, Golgi apparatus, chloroplasts, lysosomes, and cilia
  • You need to understand the role of the cell membrane as a highly selective barrier that carries out passive and active transport.
