The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

What is the definition of Osmosis?

• the passive movement of WATER molecules from a high to low concentration across the cell membrane.

• the state where molecules are equally concentrated (balanced) on both sides of the cell membrane.

• the process that brings LARGE particles INTO the cell through the cell membrane

• he movement of molecules across the cell membrane that REQUIRES ENERGY output from the cell

Active transport requires

• energy
• the nucleus
• chloroplasts
• lysosomes

The diffusion of WATER across a semi-permeable membrane is

• osmosis
• diffusion
• endocytosis
• exocytosis

The movement of molecules from higher concentration to lower concentration is

• diffusion
• cell division
  active transport
• active transport
• tonicity

Active transport requires ______, moves materials from __________________, and goes _______ the concentration gradient.

• No energy, low to high, against
• ATP, high to low, with
• ATP, low to high, with
• ATP, low to high, against

Osmosis is a form of ______________. 

• Passive Transport
• Active Transport

The movement of molecules against a concentration gradient

• simple diffusion
• facilitated diffusion
• active transport
• osmosis

If a cell is placed in an environment with MORE oxygen OUTSIDE the cell than inside, the cell will...

• gain oxygen

• lose oxygen

• gain water

• lose water
