Q.Differentiate nodal and internodal cells of Chara.

Step 1. The main axis of Chara alternates nodes and internodes, and the cells at each position are structurally distinct.

Step 2. Nodal cells are relatively small, and each is uninucleate, containing only a few ellipsoidal chloroplasts.

Step 3. Internodal cells, by contrast, are the elongated cell that makes up the axial/internodal region; each is multinucleate (many nuclei), possesses a large central vacuole, and contains numerous discoidal chloroplasts rather than a few ellipsoidal ones. …

Compare nuclear number, chloroplast shape/number and vacuolation between the tw …

• Reversing the comparison — assuming the smaller nodal cells are multinucleate and the larger internodal cells are uninucleate. …
