Question

Which statement about thylakoids in eukaryotes is not correct?

a. Thylakoids are assembled into stacks.

b. Thylakoids exist as a maze of folded membranes.

c. The space surrounding thylakoids is called stroma.

d. Thylakoids contain chlorophyll.

Short answer

Thylakoids exist as a maze of folded membranes is correct one.

Step-by-step solution

Definition of Thylakoids 

Thylakoids are disc-shaped structures found in chloroplast stacks.

Chlorophyll, a photosynthetic pigment that starts photosynthesis by absorbing sunlight, is incorporated in the thylakoid membrane.

The thylakoid lumen is the interior space contained by the thylakoid membrane. A granum is a stack of thylakoids surrounded by stroma, which is a fluid-filled area.

Explanation

Thylakoids are sac-like membranes that increase the amount of surface area available for solar absorption.

In chloroplasts, they are the disc-shaped structures seen in stacks.

They don't come in the form of a maze of folded membranes.
