What is Photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, primarily converting carbon dioxide and water into glucose and oxygen.

Front

What is the function of the cell nucleus?

Back

The nucleus is the control center of the cell, containing most of the cell's genetic material and regulating gene expression and cell division.

Front

What is the role of the cell membrane?

Back

The cell membrane is a protective barrier that regulates what enters and exits the cell, maintaining homeostasis.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct processes necessary for the cell's life.

Front

What is the function of the mitochondria?

Back

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

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA into polypeptide chains.

Front

What is the function of the endoplasmic reticulum?

Back

The endoplasmic reticulum (ER) is responsible for transporting and synthesizing proteins and lipids; it comes in two forms: rough ER (with ribosomes) and smooth ER (without ribosomes).

Front

What is cytoplasm?

Back

Cytoplasm is the gel-like fluid inside the cell where many chemical reactions occur, containing organelles and various molecules.

Front

What is the role of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the function of lysosomes?

Back

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