Question

6. Write your observations when you observed onion peel under the micro scope. Draw the figure fr of what you have observed. ​

Answer 1

Answer:

celline onion comprises of rectangular shape or we can say in brick shape under the microscope.

Answer 2

The onion bulb is a modification of the leaves. Onions are made up of multiple layers that are separated by thin membranes.

• Onion cell observation procedure:
• Add a drop of water to the microscopic slide's centre.
• Remove a thin membrane from the onion layer and place it in the middle of the microscopic slide (the drop of water will help flatten the membrane)
• On the onion membrane, place a drop of iodine solution (or methylene blue)
• Place a tiny coverslip on top of the membrane and gently push it down with a needle to remove any air bubbles.
• To drain excess iodine/water solution, place a blotting paper on one side of the slide
• To observe, place the slide on the microscope stage at low magnification.
• To notice clearly, adjust your focus.
• Major observations:
• Cells are large, rectangular, and interlock.
• The cells are surrounded by distinct cell walls that are clearly visible.
• The nucleus is stained darkly.
• In the middle, there are large vacuoles.
• Inside the cells, little granules may be seen (within the cytoplasm).
