FAQ: What Is Flaccid In Biology?

(in botany) Describing plant tissue that has become soft and less rigid than normal because the cytoplasm within its cells has shrunk and contracted away from the cell walls through loss of water (see plasmolysis). From: flaccid in A Dictionary of Biology ยป

What is flaccid cell in biology?

In botany, the term flaccid refers to a cell that lacks turgidity, i.e. it is not swollen and plump, but loose or floppy and the cell has become drawn in and pulled away from the cell wall (Figure 1).

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 ).

What is flaccidity in science?

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 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 does it mean by flaccid?

1a: not firm or stiff also: lacking normal or youthful firmness flaccid muscles. b of a plant part: deficient in turgor. 2: lacking vigor or force flaccid leadership.

Why does a cell become flaccid?

A plant cell in a concentrated solution (lower water potential than the cell contents) Water leaves the cell by osmosis. The cytoplasm pulls away from the cell wall (plasmolysis) and the cell becomes flaccid and the plant wilts.

What is flaccidity in muscle?

Flaccid is a decrease or lack of muscle movement where the affected body part becomes floppy or without muscle tone and with diminished reflexes.

What is the difference between flaccid and turgid give one example of flaccid condition in plants?

Flaccidity is the reverse of turgidity. Example: Weeds can be killed in a playground by sprinkling excessive salts around their base. A plant cell when immersed in hypertonic solution like salt solution for about 30 minutes will become flaccid or limp.

What is called diffusion?

Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration. Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things – it is how substances move in and out of cells.

What is flaccid and spastic paralysis?

Flaccid paralysis causes your muscles to shrink and become flabby. It results in muscle weakness. Spastic paralysis involves tight and hard muscles. It can cause your muscles to twitch uncontrollably, or spasm.

What is flaccid and plasmolysis?

flaccidity. In a strict definition, plasmolysis is the shrinking of the protoplasm due to exposure to hypertonic surrounding. Flaccidity is the loss of turgor due to the lack of net water movement between the plant cell and the isotonic surrounding.

What is Plasmolyzed in biology?

Plasmolysis is a typical response of plant cells exposed to hyperosmotic stress. The loss of turgor causes the violent detachment of the living protoplast from the cell wall. The plasmolytic process is mainly driven by the vacuole. Plasmolysis is reversible (deplasmolysis) and characteristic to living plant cells.

What is the difference between flaccid and turgid cell?

The main difference between a turgid cell and flaccid cell is that a turgid cell contains more water and a flaccid cell lacks water. In plants when the stomatal cells become turgid the guard cell opens and when they become flaccid the guard cell closes.

What is cell sap?

Cell sap is a fluid found in the vacuoles (small cavities) of the living cell; it contains variable amounts of food and waste materials, inorganic salts, and nitrogenous compounds. Phloem, or sieve-tube, sap is the fluid carrying sugar from leaves to other parts of the plant in the summer. See also cohesion hypothesis.

What Happens During Transcription In Biology?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.
