What is diffusion?

Back

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration without the use of energy.

Front

What type of cell is characterized by having a nucleus and complex internal structures?

Back

Eukaryotic cells are complex cells that contain a nucleus and various organelles.

Front

What is the equation for cellular respiration?

Front

What is the role of ATP in cellular processes?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells, providing energy for various biochemical reactions.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs obtain energy by consuming other organisms.

Front

What is the function of the nucleus in a eukaryotic cell?

Back

The nucleus houses the cell's DNA and is responsible for regulating gene expression and cell division.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, which is essential for photosynthesis.

Front

What is the process of endocytosis?

Back

Endocytosis is the process by which cells engulf substances from their external environment, requiring energy.
