What Is Flaccidity In Biology?

What is the definition of flaccidity?

1.

Lacking firmness; hanging limply: flaccid muscles.

2.

Lacking force, vigor, or effectiveness: a flaccid acting performance.

[Latin flaccidus, from flaccus, flabby.].

Is polio caused by a virus?

Polio, or poliomyelitis, is a disabling and life-threatening disease caused by the poliovirus. The virus spreads from person to person and can infect a person’s spinal cord, causing paralysis (can’t move parts of the body).

What is flaccid condition of a cell?

Flaccidity is the condition which occurs when a plant cell is placed in an isotonic solution. Flaccid cells are those whose protoplast has no turgor pressure. Plasmolysis cells are those whose protoplast has no turgor pressure and is also shrunken.

What does Turged mean?

adjective. swollen; distended; tumid. inflated, overblown, or pompous; bombastic: turgid language.

What is flaccidity and turgidity?

Turgidity: Turgidity refers to the state of being turgid or swollen due to high fluid content inside the cell. Flaccidity: Flaccidity refers to the state between turgidity and plasmolysis in which the plasma membrane is not pushed against the cell wall.

What is flaccidity explain it in terms of solutions?

Flaccidity refers to a lack of literally cellular ‘stiffness’ that results from more water leaving a cytoplasm than enters it. The suspension of cells from plants in isotonic solutions results in the state termed flaccidity.

What does turgid mean in science?

In biology, turgid refers to cells or tissues that are swollen from water uptake. Many cell types in many different organisms can become turgid due to water uptake. … This swells the vacuole, creating a pressure on the walls of the cell. This pressure is called turgor pressure.

What is turgor in biology?

Turgor, Pressure exerted by fluid in a cell that presses the cell membrane against the cell wall. Turgor is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.

What is Crenation in biology?

Crenation (from modern Latin crenatus meaning “scalloped or notched”, from popular Latin crena meaning “notch”) in botany and zoology, describes an object’s shape, especially a leaf or shell, as being round-toothed or having a scalloped edge.

What does flaccid mean in osmosis?

If a plant cell is surrounded by a solution that contains a lower concentration of water molecules than the solution inside the plant cell, water will leave the cell by osmosis and the plant cell will become flaccid (soft).

Whats a osmosis?

Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes).

Is polio A virus?

Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person. Polio is more common in infants and young children and occurs under conditions of poor hygiene.

What causes flaccidity?

This abnormal condition may be caused by disease or by trauma affecting the nerves associated with the involved muscles. For example, if the somatic nerves to a skeletal muscle are severed, then the muscle will exhibit flaccid paralysis. When muscles enter this state, they become limp and cannot contract.

What does Plasmolysed mean in biology?

Plasmolysis. When too much water moves out of a plant cell the cell contents shrink. This pulls the cell membrane away from the cell wall. A plasmolysed cell is unlikely to survive.

What is turgidity and Plasmolysis?

Plasmolysis refers to the process in which plant cells lose water in a hypertonic solution, while turgidity refers to the state of plant cells being swollen due to high fluid content.

What is incipient Plasmolysis?

Incipient plasmolysis is defined as the osmotic condition where 50% of the cells are plasmolysed. At this point, the osmotic potential inside the cell matches the osmotic potential of the medium on average.

What is flaccidity in muscle?

Muscle flaccidity HP:0010547 A type of paralysis in which a muscle becomes soft and yields to passive stretching, which results from loss of all or practically all peripheral motor nerves that innervated the muscle.
