Question

cells of other organisms

1. observe organism 2, the diatom

identify which organelles are vis
visible organelles sample 2
nucleus a
chloroplasts b
mitochondria c
cell membrane d
cell wall e

Explanation:

1. Nucleus: Diatoms are eukaryotes, so they have a nucleus, but it is not clearly visible in this micrograph.
2. Chloroplasts: The distinct yellow-green, striped structures running along the length of the diatom are chloroplasts, which are clearly visible.
3. Mitochondria: These small organelles cannot be resolved at this magnification and are not visible.
4. Cell Membrane: While present, it is thin and obscured by the thick cell wall, so it is not visible.
5. Cell Wall: The thick, rigid, clear outer structure surrounding the diatom's cell is its silica-based cell wall (frustule), which is clearly visible.

Answer:

Nucleus: (Select option for "Not Visible")
Chloroplasts: (Select option for "Visible")
Mitochondria: (Select option for "Not Visible")
Cell Membrane: (Select option for "Not Visible")
Cell Wall: (Select option for "Visible")
