Question

1. what is the structure called at #5 *

1 point
options:
stroma
thylakoid
lamellae
cytoplasm
granum

Explanation:

The diagram appears to be of a chloroplast. In a chloroplast, the stroma is the fluid - filled matrix surrounding the thylakoid stacks. The structure labeled #5 is in the region surrounding the thylakoid (stacked structures like 6). Stroma is the correct term here as thylakoid is the individual disc, granum is the stack of thylakoids, lamellae connect grana, and cytoplasm is not the term for this chloroplast - specific region.

Answer:

A. Stroma
