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 the law of conservation of mass?

Back

The law of conservation of mass states that in a closed system, the mass of the reactants must equal the mass of the products in a chemical reaction.

Front

What role does the cell membrane play in a cell?

Back

The cell membrane regulates what enters and leaves the cell, maintaining homeostasis by controlling the movement of substances.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions, such as the nucleus, mitochondria, and chloroplasts.

Front

What is the function of chloroplasts?

Back

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

Front

What is evolution?

Back

Evolution is the process by which different kinds of living organisms develop and diversify from earlier forms during the history of the earth.

Front

What is a tissue?

Back

A tissue is a group of similar cells that work together to perform a specific function in an organism.

Front

What is an organ?

Back

An organ is a structure composed of different types of tissues that work together to perform a specific function in the body.

Front

What is a system in biology?

Back

A system in biology refers to a group of organs that work together to perform complex functions, such as the circulatory system or respiratory system.
