What is the meaning of vegetative in biology?
What is the meaning of vegetative in biology?
1. ( Botany) of, relating to, or denoting the nonreproductive parts of a plant, i.e. the stems, leaves, and roots, or growth that does not involve the reproductive parts. 2. ( Biology) (of reproduction) characterized by asexual processes.
What do you mean by vegetative cells?
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;.
What is the vegetative form of a microorganism?
veg·e·ta·tive bac·te·ri·a The growing form of bacteria. This can be Low-level (LLD) which kills vegetative bacteria, and some fungi and viruses or Intermediate level that kills vegetative bacteria, mycobacteria, viruses and most fungi, or high level (HLD) that kills all microorganisms except bacterial endospores.
What is the difference between a vegetative bacterial cell and a spore?
The key difference between spore and vegetative cell is that spore is an inactive, dormant structure that is resistant to harsh environmental conditions while vegetative cell is an active normal growing cell that cannot resist harsh environmental conditions.
What is vegetative state?
A vegetative state is when a person is awake but is showing no signs of awareness. A person in a vegetative state may: open their eyes. wake up and fall asleep at regular intervals. have basic reflexes (such as blinking when they’re startled by a loud noise or withdrawing their hand when it’s squeezed hard)
Why is it called vegetative state?
The name vegetative state was chosen to refer to the preserved vegetative nervous functioning, meaning these patients have (variably) preserved sleep-wake cycles, respiration, digestion or thermoregulation.
What is vegetative cell in microbiology?
The normally-growing cell that forms the endospore is called a vegetative cell. Spores are metabolically inactive and dehydrated. They can remain viable for thousands of years. When spores are exposed to favorable conditions, they can germinate into a vegetative cell within 90 minutes.
What are vegetative cells called?
Plants, algae, fungi, and bacteria produce spores as dispersive structures. The vegetative cells of the multicellular organisms are called somatic cells.
What is vegetative cell in algae?
Vegetative cells are amoeboid, 8–10 or 12–18 μm long (depending on species), with long pseudopods. This genus is free living. It is heterotrophic, ingesting bacteria or small algae. Two to ten plastids without pyrenoids are present; reproduction occurs by endogenous cysts.
Does a vegetative cell contain DNA?
The endospores are structurally, metabolically and functionally very different from bacterial vegetative cells….Difference between Bacterial Endospores and Vegetative Cells.
| Characteristics | Vegetative Cells | Bacterial Endospores |
|---|---|---|
| Conformation of DNA | Usually B-form of DNA | Usually A-form of DNA |
What are vegetative spores?
Does vegetative cells contain DNA?
What is the meaning of ‘vegetative bacteria’?
Vegetative bacteria are the bacterial cells that are metabolizing and undergoing binary fission. They are “alive” and replicating. Some bacteria (primarily gram positive bacilli such as Clostridium and Bacillus ) can turn on a special genetic program whereby a new set of genes are expressed.
Can a bacteria live in a vegetative state?
Related Questions More Answers Below. Bacteria can live in a vegetative state in which they can grow and reproduce. Few of them can also exist in spore form which is unable to grow or reproduce but can help the bacteria to survive in an environment that is unfavourable for growth.
What does it mean to be in a vegetative state?
What Does It Mean to Be in a Vegetative State? A vegetative state, or unaware and unresponsive state, is a specific neurological diagnosis in which a person has a functioning brain stem but no consciousness or cognitive function. Individuals in an unaware and unresponsive state alternate between sleep and wakefulness.
How does a vegetative cell divide in a bacterial cell?
Normally all bacterial species exist as vegetative cells: each has a outer wall or membrane, inner cytoplasmic membrane, inside of inner membrane is cytoplasm that has a cyclic DNA molecule ( some may have one or more plasmids), some RNA molecules, etc. Te cells divide by binary fission in a nutrient envieronment.
