CH 2 CELL : THE UNIT OF LIFE

Cells in which a double nuclear membrane is present are called eukaryotic cells.

Cells in which nuclear membrane is absent are called prokaryotic cells.

The nucleus is the most important part of the cell it regulates and coordinates various life processes of the cell.

These are green-coloured plastids they are abundant in parts exposed to light.

These are coloured plastids and are present in petals of flowers and in fruits.

Leucoplast are colourless plastids it has no pigment and they store starch.

The Golgi apparatus occurs in the form of granules, filaments, or rods that are supposed to originate from the endoplasmic reticulum.

Mitochondria are called “Powerhouse of the cell” because it stores energy in the form of ATP.

Mitochondria are the sites where cellular respiration occurs to release energy. This energy is stored in the form of ATP.

The full form of ATP is Adenosine Triphosphate.
