Amoeba Sisters Video: Cell Transport
Cell Membrane Structure
Standard 1.1.1: Summarize the structure and function of organelles in eukaryotic cells (including the nucleus, plasma membrane, cell wall, mitochondria, vacuoles, chloroplasts, and ribosomes) and ways that these organelles interact with each other to perform the function of the cell.
Think about it: What properties of the membrane allow it to always arrange itself in the double membrane structure?
Diffusion
Standard 1.2.1: Explain how homeostasis is maintained in a cell and within an organism in various environments (including temperature and pH).
Think about it: When the particles have reached equilibrium, do they stop moving?
Facilitated Diffusion
Standard 1.2.1: Explain how homeostasis is maintained in a cell and within an organism in various environments (including temperature and pH).
Think about it: Which part of the cell membrane help to facilitate larger molecules across?
Osmosis (Passive Transport)
Standard 1.2.1: Explain how homeostasis is maintained in a cell and within an organism in various environments (including temperature and pH).
Think about it: Why is it that plants on the side of the road often die when roads are salted in the winter?
Active Transport
Standard 1.2.1: Explain how homeostasis is maintained in a cell and within an organism in various environments (including temperature and pH).
Think about it: How is active transport different than passive transport?
Homeostasis
Standard 1.2.1: Explain how homeostasis is maintained in a cell and within an organism in various environments (including temperature and pH).
Think about it: How does your body constantly maintain homeostasis?
