Bio Quiz #2: Cell Structure/Function, Membranes and Membrane Transp
Study online at https://quizlet.com/_hvwqn2
1. Cell Theory: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells
arise from existing cells.
2. Prokaryotic: -bacteria cells
-small and simple
-nucleoid region
-no membrane bound organelles
-cell walls
3. Eukaryotic: -plants and animals
-large and complex
-nucleus
-membrane bound organelles
-only plants have cell walls
4. Prokaryotic + Eukaryotic Shared Characteristics: -DNA
-cell membrane
-cytoplasm
5. 2 Main Parts of Cell: -Nucleus
-holds all DNA
-Cytoplasm
-where everything outside of the nucleus is located
6. Membrane Liquid Mosaic: many protein molecules floating around in the membrane liquid
7. Selectively Permeable Membrane: -some things can pass through some things can't
-allows important things to stay where they are needed
8. Why do materials need to get in + out: -waste needs to leave to be broke down or used elsewhere
-others need to stay in order to nourish the cell
9. Passive Transportation: -diffusion
-high to low
-osmosis
-no energy
--------------------------------------
-diffusion
-high to low concentration
-facilitated diffusion
