Briefly discuss the importance of chromosomes to an organism

State the difference between cell wall and cell membrane

State the difference between Nucleus and nucleolus

What is cell theory? Name the three scientists whose work led to the formulation of the cell theory.

List the major differences between a plant cell and an animal cell

Briefly describe the three essential basic parts of a cell

Match the name of the organelle given in Column A with its function given in Column B.

Column A (Organelle)		Column B (Function)
1	leucoplast	a	help in cell division
2	nucleus	b	transport of material
3	ribosomes	c	making food
4	mitochondria	d	digesting foreign bodies
5	endoplasmic reticulum	e	storage of starch and proteins
6	golgi bodies	f	making the cell turgid
7	chloroplast	g	making proteins
8	centrosome	h	controlling all the vital activities of a cell
9	vacuole	i	releasing energy
10	lysosomes	j	synthesis of cell wall in a plant cell

Vacuoles are filled with a fluid called nucleoplasm

;Chromoplasts are the kitchen of the cell

Every cell is bound by a cell wall

Golgi bodies form a network of tubes which run throughout the cytoplasm

A mitochondrion is bound by two membranes
