Question

cells can be stained using fluorescent dyes that bind specifically to different biomolecules in cells. when cells stained this way are viewed with a fluorescent microscope, the biomolecules appear to glow with different fluorescent colors. the cellular targets of these stains and the colors they appear are as follows: dna: blue atp: red low ph value: yellow while working in a research lab, you are given a tube that says “eukaryotic cells,” from which you prepare stained cell preparations using the fluorescent dyes mentioned. when you look at the preparation with a fluorescent microscope, you see cells with organelles fluorescing blue, red, and yellow. match the organelle to the correct color it could be fluorescing mitochondria choose chloroplast choose lysosome choose nucleus choose

Explanation:

1. Mitochondria produce ATP, so they would fluoresce red as ATP stains red.
2. Chloroplasts also have DNA, so they would fluoresce blue as DNA stains blue.
3. Lysosomes have a low - pH environment, so they would fluoresce yellow as low pH values stain yellow.
4. The nucleus contains DNA, so it would fluoresce blue as DNA stains blue.

Answer:

mitochondria: red
chloroplast: blue
lysosome: yellow
nucleus: blue
