Cell Biology and Structure

Mitochondrion takes energy from carbohydrates/food and forms ATP molecules, and is the power house of the cell.

Nucleus is the largest cell organelle, which can be easily identified under the microscope.

Transfer of chemical energy into utilisable biological energy takes place in mitochondia in the form of ATP.

Lysosomes are called 'suicidal bags' because of hydrolytic enzymes, which digest their own cell organelles.

Micochondria are called the 'power houses of the cell' because they contain ATP.

Dictyosomes secrete various essential vitamins and enzymes.

Smooth endoplasmic reticulum (SER) is the site of lipid synthesis.

Mitochondria is called the 'power house of the cell' as it stores energy in the form of ATP.

The cells, which are metabolically more active possess higher number of mitochondria because of higher energy requirement.

Infoldings of a mitochondria on which ATP synthesis occur are called the cisterns.

Due to the presence of ribosomes on the surface of endoplasmic reticulum, it appears rough.

This is the correct option. In cytoplasm and mitochondria, the breakdown of complex molecules to yield energy takes place.

These are the thread like structures found in the nucleus of a cell.

Cilia and flagella are extensions of protoplasm.

The goblet cells of the intestinal epithelium are examples of unicellular glands.
