Aim: How can we compare active and passive transport?

Passive vs. Active Transport. Passive Transport Does NOT require energy Moves substances from higher to lower concentration.

UNIT 2: What is Life? WARM UP 9-11-15 As you watch the video, answer these questions: 1) The one most important thing that makes something alive is……….. 2) Three characteristics of living things are……

Unit 2: What is Life? I. Biotic vs. Abiotic Biotic – anything that is or was alive. Abiotic – non-living things II. Cell Theory (3 parts): All living things are made of 1 or more cells The cell is the most basic unit of life Cells can only come from other cells

Writing Prompt 10-14 What activity did you enjoy most from 1st quarter? Why did you like it? Pick one activity from 1st quarter that helped you learn best. Why was it good for you?

How does a cell membrane let in fluids? IV. Osmosis and Diffusion Permeable – water / liquid can pass through. Diffusion – movement from high to low concentration (like a crowd of ppl). Osmosis – diffusion of water through a semi-permeable membrane. Cells move molecules in and out with osmosis. Water moves in and out of a cell through diffusion.
