Guida verificata passo dopo passo1
Recall the structure of a chloroplast, which includes the outer membrane, inner membrane, stroma, and thylakoid membranes.
Identify that the thylakoid membranes are stacked into grana and surrounded by a fluid-filled space.
Understand that the fluid surrounding the thylakoid membranes inside the chloroplast is called the stroma.
Differentiate the stroma from other spaces such as the thylakoid lumen (inside the thylakoid), intermembrane space (between outer and inner membranes), and matrix (a term used for mitochondria, not chloroplasts).
Conclude that the correct name for the interior fluid-filled space surrounding the thylakoid membranes is the stroma.
