vegetative cell
Học thuậtThân thiện
Definition
- Noun:
- A non-reproductive cell: A vegetative cell is any cell in a plant or animal organism that is not a reproductive cell (gamete). Its primary function is related to the growth, maintenance, and structure of the organism, rather than sexual reproduction.
- A somatic cell: It is synonymous with a somatic cell, which constitutes the body of an organism and is produced through the division of pre-existing cells via processes like mitosis.
Usage Examples
- Noun:
- The leaf is primarily composed of vegetative cells that perform photosynthesis.
- In animal tissues, damage is often repaired by the division and activity of vegetative cells.
- Unlike a sperm or egg cell, a vegetative cell does not transmit genetic material to offspring.
Advanced Usage
- In microbiology: In some contexts, particularly in bacteriology, "vegetative cell" can refer to a metabolically active, growing, and dividing bacterial cell, as opposed to a dormant spore.
- When conditions are favorable, the bacterial endospore germinates into a vegetative cell.
Variants and Related Words
- Somatic cell (n): The direct synonym for vegetative cell in multicellular organisms.
- Gamete (n): A reproductive cell (e.g., sperm, egg); the antonym in the context of cellular function.
Synonyms
- Body cell: A common, less technical term.
- Somatic cell: The precise biological synonym.
Related Phrases
- Vegetative state: A term in medicine describing a state of severe brain damage; this is a distinct, specialized usage not directly related to the cellular definition but shares the etymological root concerning basic life functions without higher activity.
- Vegetative propagation: A form of asexual reproduction in plants involving vegetative cells or tissues (e.g., cuttings, runners).
Noun
- any of the cells of a plant or animal except the reproductive cells; a cell that does not participate in the production of gametes;
- somatic cells are produced from preexisting cells
