Question

The plant specimens usually keep in water. Give reasons.

Answer 1

Answer:

Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago.[1]

Answer 2

Plant specimens are usually kept in water to maintain their fresh longevity otherwise during the sectioning of specimens for laboratory purposes, the cells get dry and blur image of the plant cell is obtained under a microscope.

• Proper pressing and mounting techniques are essential for the longevity of a collected sample.
• Plant hunting is the collection of live plant specimens from the wild.
• All live cells prefer to stay in aqueous condition for proper functioning.
• Dry cells of the plant specimens are not transparent when viewed under a microscope.
• Water maintains the cell turgidity of the plant specimen.
• Water keeps the osmotic pressure inside the cell and helps to maintain the shape and structure of the cell.
• In dehydrated cells, the inside pressure and water pushing outward are less and cells get wrinkled.
