The Plant Vacuole: A Multifunctional Organelle

Question 1

what are the equivalent of lysosomes in plant cells?

Answer 1

Vaculoes are acidic that perform silimar functions of lysosomes

Question 2

What is the provacuole?

Answer 2

analagous to an endosome but in plant cells, once the proteins go from the ER to the Golgi in plant cells

Question 3

How do vacuoles assist the cell?

Answer 3

vacuoles maintin turgor pressure, the osmotic pressure preventing plant cells from collapsing

regulate cytosolic pH, using ATP dependent proton pumps

Serve as a storage compartment:

• seed storage proteins
• malate (in CAM plants)
• Anthocyanins
• soluble and insoluble waste
