cytol

Thân thiện

A scientist examines the cytol of a plant cell under a microscope.

Definition

1. Noun:
   • The protoplasm of a cell excluding the nucleus; is full of proteins that control cell metabolism: "Cytol" is a technical term in biology referring to the entire contents of a cell, except for the cell nucleus. This substance, also commonly called the cytoplasm, is a gel-like matrix containing various organelles and is the site of most cellular activities.

Usage and Examples

• Noun:
  • Under the microscope, the cytol appeared as a dense, granular substance surrounding the nucleus.
  • The study focused on proteins transported within the cytol.
  • Disruption of the cytol can lead to cell death.

Advanced Usage Notes

• Technical Context: The term "cytol" is primarily used in specialized scientific literature. In most general biology and educational contexts, the synonym cytoplasm is far more common and preferred.
• Etymology: The word is derived from "cyto-" (meaning cell) and "-ol" (a suffix used in biochemistry, often indicating an alcohol or phenol, but here it is part of the root for a substance).

Variants and Related Words

• Cytoplasm (n): The more common and general term for the material within a cell membrane, excluding the nucleus. It is synonymous with "cytol."
  • The cytoplasm contains organelles like mitochondria and ribosomes.
• Cytoplasmic (adj): Relating to or located in the cytoplasm.
  • Cytoplasmic streaming is a process observed in plant cells.
• Cytosol (n): Refers specifically to the liquid component of the cytoplasm, excluding the organelles and insoluble particles.
  • Many metabolic reactions occur in the cytosol.

Synonyms

• Cytoplasm: The protoplasmic content of a cell outside the nucleus.
• Protoplasm (in a specific sense): While "protoplasm" can include the nucleus, in contexts contrasting with the nucleus, it can be synonymous with cytol.

Antonyms

• Nucleoplasm: The protoplasm within the nucleus of a cell.
• Karyoplasm: Another term for the substance inside the cell nucleus.
