What is the function of the Golgi apparatus in a cell?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the role of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration.

Front

What is the difference between hydrophilic and hydrophobic substances?

Back

Hydrophilic substances are 'water-loving' and mix well with water, while hydrophobic substances are 'water-fearing' and do not mix well with water.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of nucleic acids (DNA and RNA) and consist of a sugar, a phosphate group, and a nitrogenous base.
