When air dried seeds of peas come in contact with water they develop an imbibition force of?

Air dried Pea seeds on coming in contact with water can develop an imbibition pressure of up to 1000 bars (= 100 MPa).

What is imbibition pressure?

Imbibition Pressure. When the imbibant is kept in a confined area, pressure increases with an increase in the imbibant volume. This pressure is known as imbibition pressure. It is also known as the matric potential since it develops due to the matric potential of the imbibing substance.

Which type of Imbibant absorb more water dry or wet?

Temperature: Increase in temperature causes an increase in the rate of imbibition. Degree of dryness of imbibant: If the imbibant is dry it will imbibe more water than a relatively wet imbibant.

What happens in the process of imbibition?

Imbibition is a process of absorption of water by solid particles of a substance without forming a solution. The substance which absorbs the water is called imbitants, and the liquid is called imitate. For the imbibition process to occur, the imitate needs to be hydrophilic as a hydrophobic substance cannot imbibe.

Does a dry live seed contains water?

[c] A dry alive seed contains around 10-15\% water of its weight. Hence, water is considered the limiting factor for plant life, growth and development.

What happens when dry pea seeds are kept in water for few hours?

For germination dry pea seeds are initially soaked into water for few 24 hours. Then they are taken out and excess water is soaked with a paper towel. If the seeds are kept continuously under water the seeds will fail to respire and die.

What is MB Bishan?

Imbibition is a type of diffusion where the water is absorbed by the solid particles called colloids, causing an enormous increase in volume. Here, the solid substances are referred to as Imbibants and the imbibed liquid is referred to as imbibate. E.g. the absorption of water by seed or dry wood.

Which Imbibant is most efficient?

Among the agar is the most efficient imbibant. So, the correct option is B. Agar. Note:- Agar is the most powerful imbibant among these four options as it absorbs 99\% more water than its own weight and cellulose is the weakest imbibant among them.

Which among the following imbibes water earlier?

Solution: Pea seeds have a cell membrane that can allow passage of water easily. This means that it has a more permeable cell membrane. As a result, they imbibe more water. So, option B pea seeds are the correct answer.

Is turgor a pressure?

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.

How does water enter seed during imbibition?

The uptake of water by dry seed is called imbibition (imbibition means to drink: seeds imbibe water, you do not imbibe seeds). As seeds imbibe water, they expand and enzymes and food supplies become hydrated. Eventually the shoot will also expand and emerge from the seed.
