C. Short answers :-

1. Parts of cells :-

• cell membrane

• nucleus

• nucleolus

• nuclear membrane

• cytoplasm

• endoplasmic reticulum

• Golgi apparatus

• ribosomes

• mitochondria

• centrioles

• cytoskeleton

• vacuoles

• vesicles

2. Difference between unicellular and multicellular organisms :-

• Unicellular organisms are made

up of only one cell that carries out all

of the functions needed by the organism, while multicellular organisms use many different cells to function.

• Multicellular organisms are

composed of more than one cell, with groups of cells differentiating to take

on specialized functions
