what stains can be used in the experiment to observe the nucleus in onion peel cells?
Answers
Answer:
Iodine– dark stain that colors starches in cells. In an onion cell, it will make the cell wall more visible. It provides some contrast for viewing under a microscope. Methylene Blue– a blue stain that will color blood, bacteria, acidic or protein rich cell structures like nucleus, ribosomes, and endoplasmic reticulum
Answer:
Safranin Stain or Iodine
Explanation:
The cell is transparent, making it difficult to see the cells as they are. Staining gives a cell or its components colour, increases contrast, and makes it easier to observe the cell structure.
The organelle mitochondria in an onion peel are stained and observed using the Safranin stain. Safranin stain is a pink-colored biological stain that is commonly used in biological research for staining.
Iodine is a black stain that stains cell starches. It will make the cell wall more visible in an onion cell. It adds contrast to the image when viewed via a microscope.
