What does vegetative mean in microbiology?
Vegetative cells are any cells of the body except those which take part in the production of gametes. These cells are produced from the cells which pre-exist through the process of asexual reproduction. In bacteria, the normal living cells are vegetative cells.
What is vegetative bacterial cell?
Bacteria can form endospores in approximately 6 to 8 hours after being exposed to adverse conditions. 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.
What is the meaning of vegetative in biology?
Medical Definition of vegetative 1a(1) : growing or having the power of growing. (2) : of, relating to, or engaged in nutritive and growth functions as contrasted with reproductive functions a vegetative nucleus. b : of, relating to, or involving propagation by nonsexual processes or methods.
What is vegetative and spore form of bacteria?
Spores are inactive and dormant structures. Vegetative cells are actively growing cells that form the endospore. They can tolerate stress like chemicals, heat and radiation. They cannot manage in stressful environments.
What is vegetative part?
Vegetative parts- Parts of a plant which do not participate in sexual reproduction process are called vegetative parts. Roots, stems and leaves are the vegetative parts of a plant. 2. Reproductive parts- Parts of a plant which participate in the sexual reproduction process are called reproductive parts.
What is vegetative state?
A vegetative state is a disorder of consciousness or an altered consciousness. It is caused by severe brain damage. Someone in a persistent vegetative state may look like they’re awake, but they don’t have an awareness of their surroundings.
Where is vegetative cells found?
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;.
Is salmonella a vegetative pathogen?
Cooking is performed for two primary reasons: to make food palatable and to make it safe by eliminating vegetative pathogens such as Salmonella, L. monocytogenes, and enteropathogenic E. coli.
What is a vegetative body?
A person in a vegetative state, however, has many normal physical functions, including heartbeat and breathing. They sleep and wake up in typical patterns. They may chew and swallow food. They may make sounds, though they don’t use language. They keep their eyes open when they are awake.
What is vegetative growth?
The period of growth between germination and flowering is known as the vegetative phase of plant development. During the vegetative phase, plants are busy carrying out photosynthesis and accumulating resources that will be needed for flowering and reproduction.
What is the difference between vegetative and reproductive?
Vegetative growth favors development of roots and shoots for a strong plant structure and leaves for photosynthesis. Reproductive growth favors flowering and fruit formation for development of a marketable crop.
What causes a vegetative state?
Most commonly, a vegetative state is caused by severe brain damage due to a head injury or a disorder that deprives the brain of oxygen, such as cardiac or respiratory arrest.
What are vegetative symptoms?
Vegetative symptoms are disturbances of a person’s functions necessary to maintain life (vegetative functions). These disturbances are most commonly seen in mood disorders, and are part of the diagnostic criteria for depression, but also appear in other conditions.
What is the role of vegetative cell?
The vegetative cell forms the pollen tube that delivers the sperm to the embryo sac. One sperm cell fertilizes the egg to produce the zygote, and the second sperm cell fuses with the central cell to produce the endosperm (3).
What is the other name of vegetative cell?

Is E coli a vegetative cell?
Vegetative cell division in E . coli and in B . subtili s. The basic process of cell division is conceptually similar in eukaryotic and prokaryotic cells and is characterized by the creation of a division septum between the recently duplicated chromosomes.
What is the difference between endospores and vegetative cells?
While the vegetative cell is the active form for bacterial cells (growing, metabolizing, etc), the endospore can be thought of as a dormant form of the cell. It allows for survival of adverse conditions, but it does not allow the cell to grow or reproduce.

What is vegetative growth in bacteria?
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.
