Question

how do you observe the cells in onion peel under microscope draw and label the diagram write your observation

Answer 1

There are a large number of regularly shaped cells lying side by side and each cell has a distinct cell wall. A distinct nucleus is present on the periphery of each cell. ... A large vacuole is present at the centre of each cell, and is surrounded by the cytoplasm.


Hope it helps you....

Answer 2

STEPS TO OBSERVE THE CELLS IN ONION PEEL UNDER A MICROSCOPE:

• Onions fall under the genus cotyledons
• Onions are made up of fleshy layers that are divided by a thin membrane.
• For this experiment, we will use the membrane which can be easily obtained by removing it with the help of tweezers

To prepare the wet mount slide:

• Add a tiny drop of water at the center of the slide
• Put the onion membrane over the drop of water.
• stain the membrane with methylene blue or iodine
• cover the slide with a cover slip with a help of tweezers making sure to avoid any trapping of air bubbles.
• Place the prepared slide under a microscope and observe.

OBSERVATION:

• Cells are linear, individual and rectangular shape.
• The size of each cell ranges from 0.25 to 0.4 meters in length.
• The cell are surrounded by cell wall which helps the cell in retaining their distinct shape.
• A distinct stained nucleus is present that is positioned towards the periphery of cell.
• A large vacuole is present at the centre of the cell
