Waste Removal Structures

Question 1

What organelles have a roll in removing waste products?

Answer 1

• Endoplasmic Reticulum (ER)
• Golgi Apparatus
• Lysosomes
• Plasma membrane

Question 2

What is the endoplasmic reticulum and its function?

Answer 2

• Interconnecting membrane sheets that divide the cytoplasm into compartments
• Produces vesicles to transport proteins within (intracellular) and between (intercellular) cells.

Question 3

What is the Golgi Apparatus?

Answer 3

A system of membranes within the cytoplasm that are able to pinch off into vesicles, which transport contents to the plasma membrane and discharge them using exocytosis.

Question 4

What are lysosomes?

Answer 4

Organelles from Golgi bodies that have digestive enzymes which break down/recycle macromolecules.

Question 5

What is the plasma membrane?

Answer 5

• Membrane that surrounds all cells
• Allows small and large molecules in and out through endocytosis and exocytosis

Question 6

What is endocytosis?

Answer 6

• “En”docytosis = in
• Molecule is enclosed within the vesicle which pinches off and transports it within the cell

Question 7

What is exocytosis?

Answer 7

• “Ex”ocytosis = exit
• Molecule transported by vesicle which joins with membrane surface and releases contents out
