Question

cells of other organisms 1000x dinobyon organism 3 change 8. observe organism 3, dinobyon. identify which organelles are visible in this sample. i need a hint visible organelles sample 2 nucleus a chloroplasts b mitochondria c cell membrane d cell wall e

Explanation:

Dinobryon is a photosynthetic protist (a type of golden algae). Under 1000x magnification:

1. Chloroplasts: The greenish, oval structures visible in the cells are chloroplasts, which are large enough to be seen at this magnification due to their size and pigmentation.
2. Cell Membrane/Cell Wall: The distinct outer boundary of each Dinobryon cell (the vase-like structure) corresponds to a cell wall (a defining feature of this alga) and the underlying cell membrane, which form the visible cell shape.
3. Nucleus: A darker, rounded structure within some cells is the nucleus, which is large enough to resolve at 1000x.
4. Mitochondria: These are too small to be visible under light microscopy at 1000x without special staining, so they cannot be identified here.

Answer:

A. Nucleus: Visible
B. Chloroplasts: Visible
C. Mitochondria: Not Visible
D. Cell Membrane: Visible
E. Cell Wall: Visible
