Chlamydomonas reinhardtii Microscopic Structure Diagram #320239 (License: Personal Use)

This black-and-white scientific illustration depicts the internal ultrastructure of Chlamydomonas reinhardtii, a model organism in plant biology. Key features include two anterior flagella for motility, a cup-shaped chloroplast with pyrenoid, a prominent nucleus, an eyespot (stigma) for phototaxis, and contractile vacuoles. The stippled shading indicates cytoplasmic density and organelle boundaries.

Used in academic textbooks, university lecture slides, and biology websites to teach cell biology, photosynthesis, and eukaryotic microalgae structure; targets students, educators, and researchers seeking accurate morphological reference.
