Diffusion & Osmosis Intro

Diffusion & Osmosis Intro

Cell are constantly absorbing and releasing things into their surroundings.

Multiple Choice

What is the organelle that surrounds the outside of every cell?

• Cell Membrane

• Nucleus

• Cytoplasm

• Lysosome

The cell membrane controls what enters and exits the cell

The membrane is selectively permeable, which means it allows some things in and out of the cell - but not all things. (It's selective)

Multiple Choice

Things enter and exit the cell membrane in two ways.

Which way do you think happens on its own?

• active transport

• passive transport

Multiple Choice

Things enter and exit the cell membrane in two ways.

Which way do you think requires energy?

• active transport

• passive transport

Today we are going to learn about passive transport

Now practice other things we have learned while you wait on class to start.

Multiple Choice

Which statement is a part of the cell theory?

• all cells come from preexisting cells
• bacteria are prokaryotic cells
• eukaryotic cells are complex
• humans are multicellular

Multiple Choice

The ___ is the basic unit of sturucture and function of organisms

• atom
• cell
• matter
• all other answers are correct

Multiple Choice

"Garbage collectors" of the cell that remove waste:

• Cell Membrane

• Centrioles

• Lysosomes

• Nucleus

Multiple Choice

The control center that controls all the functions of the cell

• cytoplasm
• cell wall
• cell membrane
• nucleus

Multiple Choice

I make proteins for the cell. What am I?

• ribosome

• cell membrane

• nucleus

• chloroplast

Multiple Choice

Multiple Choice

Looking in a microscope, you see cells that have rectangular shapes and a green color. What type of cells are you probably viewing?

• plant cells

• animals cells

• muscle cells

• blood cells

Multiple Choice

What is the function of a chloroplast?

• makes proteins for animal cells

• allows materials in and out of the cell

• provides structure and support
