2.
Cell wall is formed from inner side therefore secondary wall formed before primary wall
3.
Middle lamella glues the different neighbouring cells together
4.
Pits are present in secondary wall

(2) Forming face of golgi body
(3) Primary lysosome for intercellular digestion
(4) Plasma membrane to remove them out from cell
Fluidity of the cell membrane is measured
(1) On the amount of cholesterol and protein in membrane
(2) On the amount of carbohydrate in membrane
(3) On the lateral movement of proteins within the overall bilayer
(4) On the flip-flop movement of protein

(1) SER
(2) Golgi bodies
(3) Ribosomes
(4) Peroxisome
The content of nucleolus is continuous with nucleoplasm
1. Through microtubules

The central part of proximal region of centriole is called hub which is made of
(1) Protein
(2) Lipoprotein
(3) Phospholipid
(4) Oligosaccharide
Glycosylation, general secretion and recycling of broken plasma membrane are functions specifically performed by
(1) Glyoxysome
(2) SER

Many of the organelle show coordination in their functions and are considered together as an endomembrane system. Find odd one out with respect. this statement
(1) ER
(2) Golgi complex
(3) Vacuole
(4) Plastid
Correct statement in relation to vacuoles is
| 1. | It is a triple membrane bound space found in cytoplasm containing sap |
| 2. | It can occupy 90% of cell volume in plants |
| 3. | Its membrane allows transport of materials along the concentration gradient only |
| 4. | Concentration of ions is significantly lesser in vacuole than cytoplasm |
A nuclear pore allows
(1) Unidirectional movement of DNA
(2) RNA movement only
(3) RNA and protein movement
(4) Protein movement only
