Vacuoles

Answer 1

Non cytoplasmic area bounded by tonoplast

Question 2

tonoplast

Answer 2

Semipermeable membrane around vacoules this thing have higher concentration and facilities are transport of ions

1. Contractile vacuole
2. Food vacuole
3. Sap vacuole
4. Gas vacuoles

Question 4

Contractile vacoule

Question 5

Food vacuole

Answer 5

In protists
Formed by engulfing food particles

Question 6

Gas vacuoles

Answer 6

Also called as pseudo vacuoles membraneless vacuole found in prokaryotes to provide buoyancy

Question 7

Func of vacuoles

Answer 7

Reservoir of sugar, Aster, amino acids, some water soluble pigments

Question 8

Percent of area covered by vacuoles in mature plant cell

Answer 8

90%

Question 9

What does vacuoler SAP do

Answer 9

Determine osmotic concentration of plant cell

Question 10

Microbodies

Answer 10

Single membrane bound and involved in oxidation other than respiration

Question 11

Where is lysosome formed

Answer 11

Formed by the packaging in Golgi apparatus

Question 12

Which is known as the suicide bags of the cell

Answer 12

Lysosomes

Question 13

What r lysosomes involved in

Answer 13

Involved in intercellular and extracellular scavenging

Question 14

Structure of lysosome

Answer 14

Has vacuole bound by membrane reservoir of approximately 50 hydrolytic enzymes which are optimum functional at acidic PH

For example acid hydrolases like amylase nucleus Peptodasd lipase

Question 15

Types of lysosomes

Answer 15

1primary
2. Secondary
3. Autophagic
4. Tertiary residual bodies

Question 16

What is pyelonephritis. How is it caused.

Answer 16

It is the inflammation of kidney.
It is caused due to the malfunctioning of lysosomal enzyme degenerative disorder

Question 17

Autophagic lysosome

Answer 17

Found by the union of primary lysosomes around dead or old organelles which surround them with vacuolar membrane and digest them by autolysis or autodigestion.

Question 18

primary lysosomes

Answer 18

Newly synthesis lysosome with inactive enzymes
