Vacuoles

Know about the building blocks of life and cells with vacuoles

1. VACUOLES The Fundamental Unit of Life 5.2.5(vi) MADE BY- AMAN GOEL

2. WHAT ARE VACUOLES ! THEY ARE FLUID FILLED SACS FOR STORAGE. THEY ARE SACS THAT STORES WATER, FOOD AND OTHER MATERIAL NEEDED BY THE CELL. THEY CAN ALSO STORE WASTE PRODUCTS UNTIL THE WASTES ARE REMOVED. Vacuoles 2

3. WHAT THEY STORE? WATER AND FOOD WASTE UNDIGESTED NUTRIENTS MINERALS PROTEINS SUGARS PIGMENTS AMINO AND OTHER VARIOUS ORGANIC ACIDS Vacuoles 3

4. COMPARISON on basis of vacuoles they have Vacuoles 4 Vacuoles of Animal cells are smaller in size Vacuoles of Plant Cells are larger in size

5. CELL HAS A BASIC STRUCTURAL ORGANISATION ! EACH CELL ACQUIRES IT’S STRUCTUE AND ABILITY TO FUNCTION BECAUSE OF ORGANIZATION OF IT’S MEMBRANE AND ORGANELLES IN SPECIFIC WAYS . THIS HELPS THE CELL TO PERFORM FUNCTIONS LIKE RESPIRATION , OBTAINING NUTRITION AND CLEARING OF WASTE MATERIAL OR FORMING NEW PROTEINS Vacuoles 5

6. QUESTIONS IF THE ORGANISATION OF THE CELL IS DESTROYED DUE TO SOME PHYSICAL OR CHEMICAL INFLUENCE, WHAT WILL HAPPEN ? Cell is the smallest unit of life, which is capable of all living functions. If the organisation of a cell is destroyed due to some physical or chemical influence, then the ability of the cell to perform all living functions such as respiration, nutrition, excretion, etc. would be affected . Vacuoles 6

7. QUESTIONS IDENTIFY THE CELL (ANIMAL/PLANT) AND GIVE REASONS FOR THE SAME? Vacuoles 7 (a) (b)

8. ANSWER-2 (a)THE FIGURE A SHOWS AN ANIMAL CELL BECAUSE NEITHER ANY VACUOLE NOR CELL WALL IS VISIBLE AND NUCLEUS IS LOCATED AT THE CENTRE (b)THE FIGURE B SHOWS A PLANT CELL BECAUSE IT HAS A LARGE VACUOLE , CELL WALL IS ALSO PRESENT IN ADDITION TO CELL MEMBRANE AND NUCLEUS IS LOCATED IN THE CORNER. Vacuoles 8 (a) (b)
