MOVEMENTS INTO CELLS - IONIC BONDING

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

_______ regulates what enters and leaves a cell.  

• Cell Membrane
• Nucleus
• Mitochondria
• Cytoplasm

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

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

Active transport requires

• energy
• the nucleus
• chloroplasts
• lysosomes

The movement of molecules from higher concentration to lower concentration is

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

The diffusion of WATER across a semi-permeable membrane is

• osmosis
• diffusion
• endocytosis
• exocytosis

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

Which diagram best shows the end result of diffusion?

• F
• G
• H
• J

Osmosis is a form of ______________. 

• Passive Transport
• Active Transport
