What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. It occurs in the mitochondria of cells.

Front

What is homeostasis?

Back

Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in external conditions.

Front

What role do enzymes play in biological processes?

Back

Enzymes are biological catalysts that speed up chemical reactions in cells without being consumed in the process.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is the significance of Gregor Mendel's work?

Back

Gregor Mendel is known as the Father of Genetics for his foundational work on the inheritance of traits in pea plants, establishing the basic laws of heredity.

Front

What is a complex carbohydrate?

Back

Complex carbohydrates are made up of long chains of sugar molecules and include starches and fibers, providing energy and structural support.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis and protecting the cell's internal environment.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is essential for cellular respiration as it acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.
