The Large Central Vacuole develops

Answer 29

Develops from small vacuoles

Question 30

role of central vacoule

Answer 30

1. Helps provide rigidity to living cells 2. Helps maintain homeostasis in cell 3. Contains cell sap

Question 31

Cell Sap of Vacuole

Answer 31

It is acidic * Contains: – Water – Wastes – Oils – Sugars – Proteins -Plant pigments -salts

Question 32

plant pigments

Answer 32

e.g. anthocyanins: water soluble, red, purple, blue pigments (color is pH dependent) – Japanese barberry – Red cabbage – Cherries – Hydrangeas

cell saps salts

Answer 33

Can form crystals – e.g. Calcium oxalate crystals (high amount in spinach, rhubarb, Swiss chard, (can promote kidney stone formation) * Types of crystals – Druses – Raphides

Question 34

Roles of crystals

Answer 34

– Defense against grazing animals and other herbivores such as insects – Regulation of calcium concentrations in cells and tissues
