Front

What are organic molecules?

Back

Organic molecules are compounds that contain carbon and are found in living organisms. Examples include carbohydrates, proteins, lipids, and nucleic acids.

Front

What is tissue?

Back

Tissue is a group of cells that work together to perform a specific function in an organism. Examples include muscle tissue and nervous tissue.

Front

What is active transport?

Back

Active transport is the process by which cells move substances across their membrane against a concentration gradient, using energy (ATP).

Front

What is gel electrophoresis?

Back

Gel electrophoresis is a laboratory technique used to separate DNA, RNA, or proteins based on their size and charge, often used to analyze genetic relationships.

Front

What is paper chromatography?

Back

Paper chromatography is a technique used to separate and identify mixtures of substances, such as color pigments, based on their different rates of movement across a medium.

Front

What are the products of cellular respiration?

Back

The products of cellular respiration are carbon dioxide, water, and energy (ATP).

Front

What are the raw materials of photosynthesis?

Back

The raw materials of photosynthesis are carbon dioxide and water, which are converted into glucose and oxygen using sunlight.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along a concentration gradient.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration until evenly distributed.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
