Cell Processes

The diffusion of WATER across a semi-permeable membrane is

• osmosis
• diffusion
• endocytosis
• exocytosis

What is diffusion

• active transport
• passive transport
• cell division
• cell mutation

What organelles are only found in PLANT cells

• lysosomes & centrioles
• cell wall & chloroplasts
• nucleus & nucleolus
• mitochondria & ribosomes

Active transport requires

• energy
• the nucleus
• chloroplasts
• lysosomes

water moves from

• higher conc. H20 => lower conc H20
• lower conc. H20 => higher conc. H20

The cell membrane

• regulates what enters/leaves cell
• helps maintain homeostasis
• keeps contents of cell in place
• all of the above

What is facilitated diffusion?

• Transport that uses proteins to help move molecules across the membrane. 
• Movements of substances through a membrane. 
• When molecules spread from High to Low concentration on their own. 
• When pressure pushes something through a membrane. 

Movement of materials through a vesicle into the cell that requires energy is 

• exocytosis
• endocytosis 
• osmosis 
• simple diffusion 

Active transport does not require energy.

• True 
• False 

Molecules using simple diffusion move from 

• high to low concentrations 
• low to high concentrations 
• no concentrations  
• both concentrations
