Name: _______________________________________ Day 13 Family:_________________________ Cell Biology Study Guide- Answer Key Things to Know for the Quiz: 1. Eukaryotic vs. Prokaryotic Cells 2. Cell Organelles, Differences between Plant and Animal Cell 3. Cell Membrane vs. Cell Wall 4. Why the Cell Membrane is Selectively Permeable? How does this relate to why it is has 4 types of cell transport? a. Diffusion b. Osmosis c. Facilitated Diffusion d. Active Transport. Plant Cell Animal Cell Cell Wall No Cell Wall Chloroplasts No chloroplast Large vacuole Small vacuole Cell Membrane Cell Wall Selectively permeable Keeps Cell shape Made up of a phospholipids bilayer Protects the cell from over expansion Maintain homeostasis (equilibrium) Type of Cell Transport Active/ Passive What molecules? Direction Protein channel? Diffusion Passive Molecules just pass High low No Facilitated Diffusion Passive Larger molecules ex: glucose High low No Osmosis Passive Water High low No Active Transport Active Larger molecules Low high YES Types of Cells ___Prokaryotic___: small and simple, no membrane-bound organelles (like the nucleus). Contain DNA and ribosomes Bacterial Cells ____Eukaryotic______: generally larger, more complex, has a nucleus Plant Cells Animal Cells Organelles in the Cell ___Nucleus____: one per cell. Has its own membrane, contains DNA, controls cell activity __Nucleolus_____: one per cell. Structure within the nucleus where ribosomal mRNA is made, high concentration of DNA and proteins __Ribosomes______: many per cell. Where proteins are made _Lysosomes_______: many per cell. Break down waste. __Vacuole____: many per animal cell, one large one per plant cell. Store substances. Holds water in plant cell. __Endoplasmic Reticulum______: one complicated structure per cell. Transports substances within the cell. Some has ribosomes attached to the surface (rough ER) and some does not (smooth ER) ___Golgi Apparatus_____: one complicated structure per cell. Prepares and packages substances for transport out of the cell. __Mitochondria_____: many per cell. Provide energy for all cellular activities ___Chloroplast_____: many per cell. Only in plant cells. Convert energy from the sun to chemical energy stored as sugar to be used by the mitochondria
