1. The nucleoplasm is continuous with the cytoplasm of a cell through:
(a) Centriole
(b) Endoplasmic reticulum
(c) Nuclear pores
(d) Golgi apparatus
2. Under a microscope, Pooja observes a cell that has a cell wall but no distinct
nucleus. The cell that she observes is
(a) a plant cell
(b) an animal cell
(c) a nerve cell
(d) a bacterial cell
3 Golgi complex was first recognised in

DIRECTION: Question nos. 4 and 5 below consist of two statements - Assertion
(A) and Reason (R). Answer these questions selecting the appropriate option
given below:
A: If both assertion and reason are true and the reason is the correct explanation
of the assertion.
B: If both assertion and reason are true but reason is not the correct explanation
of the assertion.
C: If assertion is true but reason is false.
D: If both assertion and reason are false.
4 Assertion- Lysosomes are called suicide bags of the cell.
Reason- Lysosomes carry on autolysis (autophagy) in the cell.
5 Assertion- The number of mitochondria in a cell do not correspond to the function
of the cell.
Reason-Mitochondria are common to both plant and animal cells.
6 Give scientific reason for the following:
(a) Inner membrane of mitochondria is deeply folded.
(b) Mitochondria are able to make some of their proteins.
(c) Golgi apparatus also called the secretory organelle of the cell
7 (a) Define membrane biogenesis?
(b) What is the functional difference between a plasma membrane and cell wall?
