What is the function of mitochondria in a cell?

Back

Mitochondria are known as the 'powerhouse' of the cell, as they produce ATP (adenosine triphosphate), which is the main energy currency of the cell.

Who proposed that all plants are made of cells?

Back

The scientist who proposed that all plants are made of cells is Matthias Schleiden.

Front

What is a prokaryote?

Back

A prokaryote is a microscopic single-celled organism that lacks a distinct nucleus with a membrane and other specialized organelles.

Front

What is the primary role of chloroplasts in plant cells?

Back

Chloroplasts are the site of photosynthesis, where light energy is converted into chemical energy in the form of glucose.

Front

What is ATP and why is it important for cells?

Back

ATP (adenosine triphosphate) is the main energy carrier in cells, providing the energy needed for various cellular processes.

Front

What are the main differences between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various specialized organelles.

Front

What organelle is responsible for protein synthesis?

Back

Ribosomes are responsible for protein synthesis in both prokaryotic and eukaryotic cells.

Front

What is the role of the endoplasmic reticulum (ER) in a cell?

Back

The endoplasmic reticulum (ER) is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), as well as the transport of materials within the cell.

Front

What is the function of the Golgi apparatus?

Back

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

Front

What is the role of lysosomes in a cell?

Back

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.
