Definition: The process by which organisms detect and respond to chemical signals in their environment through specialized sensory organs.

Example: Chemoreception allows animals to find food and avoid danger by sensing chemicals in the air or water.

Definition: Able to detect and respond to chemical signals or substances in the environment.

Example: The chemoreceptive cells in the nose help us smell different odors.

Definition: A type of cell or organ in the body that detects chemicals in the environment, helping us to sense things like taste and smell.

Example: The chemoreceptor in the nose helps us detect different scents.

Definition: A medical procedure that involves using chemicals to destroy or remove unhealthy tissue, often used for treating skin lesions or other diseases.

Example: The doctor recommended chemosurgery to treat the patient's skin cancer.

Definition: Relating to a type of surgery that uses chemicals to treat diseases, especially cancer.

Example: The doctor recommended a chemosurgical approach to remove the tumor.

Definition: The process by which certain organisms create food using energy from chemical reactions, rather than from sunlight.

Example: Some bacteria use chemosynthesis to produce energy in environments without sunlight.

Definition: Relating to or involving the process of chemosynthesis, where organisms create energy from chemical reactions instead of sunlight.

Example: Some bacteria are chemosynthetic, using chemicals from their environment to produce energy.

Definition: Relating to the movement of cells or organisms in response to chemical stimuli.

Example: The chemotactic response of the bacteria allows them to move toward nutrients.

Definition: The movement of an organism or cell in response to a chemical signal, either moving towards or away from it.

Example: Bacteria use chemotaxis to find food sources in their environment.

Definition: Relating to the classification of organisms based on their biochemical characteristics.

Example: The chemotaxonomic analysis revealed new insights into the plant species' relationships.
