What do we call the process of molecules moving across a membrane?
Diffusion
What inspired Robert Hooke to give cells the name "cell"?
he thought they looked like a monk's cell (bedroom)
Which scientist is responsible for giving cells the name "cell"?
Robert Hooke
Plant and animal cells have one major difference when it comes to their outermost layer. How could you tell the difference between a plant cell and an animal cell just by looking at the outside?
Plant cells have a cell wall and a membrane, animal cells just have a membrane

Ribosomes
What two macromolecules make up the majority of the cell membrane?
Proteins and Lipids

An owlet
What are the 3 components of the cell theory?
1. cells are the basic unit of life
2. all living things are made of cells
3. all cells come from pre-existing cells

Hypertonic
Which planet in our solar system has the shortest day?

Which scientist was the first to propose that all animal are made of cells?
Schwann
What organelle do both plants and animals have, that looks completely different based on if it is a plant or animal cell?
Vacuole! (plants have a large central vacuole while animals have smaller vesicles)
What organelle is responsible for breaking down and recycling old cell components/macromolecules?
Lysosomes
A cell is soaked in a solution containing 2% solute and 98% water. The cell contains 8% solute 92% water. Using your white board tell me:
1. what type of solution this is
2. where water will diffuse/move
3. what will happen to the volume of the cell
1. the solution is hypotonic
2. water will move into the cell
3. the volume will increase/the cell will grow
