Read the following statements carefully
A. Lipid component of the plasma membrane mainly consists of phosphoglycerides.
B. Polar molecules can pass through the lipid bilayer of plasma membrane, therefore they do not require carrier proteins to facilitate their transport.
C. Secondary wall is capable of growth and it is formed on the outer side of the cell
D. Quasi fluid nature of lipid enables lateral movement of proteins within the overall lipid bilayer of plasma membrane
E. Middle lamella glues the different neighbouring cells together
How many statements are incorrect?
1. Three
2. Five
3. Four
4. Two
The organelles formed by the process of packaging in the golgi apparatus is
1. Double membrane organelle.
2. Possess single circular DNA molecule
3. Rich in hydrolases
4. Able to occupy up to 90 percent volume of the cell
Mark the incorrect statement
1. | All the cell organelles perform different & specific function. |
2. | Basal body of cilia & flagella in prokaryotes is formed by cytoskeleton. |
3. | Endoplasmic reticulum helps in transport. |
4. | Microbodies are present in both plants and animals. |
Smooth endoplasmic reticulum performs all the
functions, except
1. Production of glycoprotein.
2. Synthesis of lipid.
3. Synthesis of glycogen.
4. Synthesis of steroidal hormones
Choose the incorrectly matched pair.
1. Contractile vacuole - Excretion.
2. SER - Steroidal hormones synthesis.
3. Xanthophyll - Fat soluble pigment.
4. Eukaryotic flagellum - Extension of basal body.
