FAQs on ICSE Class 10 Science Concise Selina Publishers Solutions Absorption By Roots
1. What is the mechanism of opening and closing of the Stomata?
The turgidity of guard cells helps in the opening and closing of the Stomata. Each guard cell has a thick wall on its side that faces the Stoma and a thin wall on the opposite side. These guard cells consist of chloroplast, which helps in the synthesis of glucose during the process of photosynthesis. Due to this process, the osmotic pressure applied by the contents in the guard cells keeps on increasing leading to more absorption of water from their neighbouring cells and makes them turgid in nature. The guard cells become more arched outwards as a result of turgor, and an aperture between them widens, opening the stomata.
2. Why do soaked seeds swell up and burst?
When seeds are soaked in water, they swell up and burst out of their seed coats. This happens because of a process known as Imbibition. Plant cells contain certain pressures known as Turgor. Due to this, hydrostatic pressure occurs on the walls of the cells absorbing the water, which leads to Endosmosis. Hence, due to Imbibition and Endosmosis, the seeds start to soak up water. There is a force that is generated when these seeds soak up water, which is strong enough to burst the seed coats. Therefore, when the seeds are soaked they swell up and burst.
3. What is Transpiration pull and how is it formed?
Due to the process of transpiration, water gets lost from the leaf surface in the form of water vapour. This leads to water molecules being pulled up due to cohesion. This continuous process of water molecules being pulled up through the stem is known as Transpiration pull. This is an important force as it enables the ascent of sap. The transpiration pull is caused by a negative pressure being produced in the Xylem of the plant. This then pulls the water from the soil to the roots.
