Definition: Referring to the nonliving substances produced by living cells during their activity.

Example: The ergastic substances in the plant cells include starch and oils.

Definition: A part of the cell's protoplasm that is involved in the formation of structures and contains ribosomes, similar to other cellular components.

Example: The ergastoplasm is essential for protein synthesis within the cell.

Definition: Relating to systems or processes that, over time, will return to a previous state or where every sample is representative of the entire system.

Example: The ergodic hypothesis suggests that, given enough time, a system will explore all its possible states.

Definition: The state or quality of a system where its time averages are the same as its ensemble averages, often used in statistical mechanics and probability theory.

Example: In statistical mechanics, ergodicity is an important concept that helps in understanding the behavior of particles over time.

Definition: A device used to measure how much work a muscle or group of muscles can do when they contract.

Example: The scientist used an ergograph to assess the strength of the athletes' muscles during training.

Definition: The study of how to design equipment and workspaces to make them comfortable and efficient for people, aiming to reduce fatigue and discomfort.

Example: The ergonomics of the new office design helped employees feel more comfortable and productive.

Definition: A person who studies how people interact with their environment, especially in terms of comfort and efficiency in the workplace.

Example: The ergonomist recommended changes to the office layout to improve employee comfort and productivity.

Definition: A chemical compound derived from ergot, used primarily to induce contractions in the uterus during childbirth.

Example: The doctor administered ergonovine to help control the bleeding after the delivery.

Definition: A type of sterol that is found in yeast and some molds, which can be converted into vitamin D when exposed to sunlight.

Example: Ergosterol is an important compound in fungi and is used in the production of vitamin D2.

Definition: A type of fungus that grows on cereal plants, replacing the grains with dark, compact masses. It can cause disease in plants and is used to produce important medicinal compounds.

Example: Farmers must be careful to prevent ergot from infecting their rye crops, as it can lead to serious health issues.
