Mitochondria & Chloroplasts
Multiple Choice
Mitochondria and chloroplasts both have folds in their inner membranes. What are these called?
A
Lamellae
B
Thylakoids
C
Cristae
D
Grana
Verified step by step guidance1
Understand the structure of mitochondria: Mitochondria have two membranes, an outer membrane and a highly folded inner membrane. The folds of the inner membrane are called 'cristae'.
Understand the function of cristae: Cristae increase the surface area of the inner membrane, allowing for more space for proteins and enzymes involved in cellular respiration to function efficiently.
Differentiate between mitochondria and chloroplasts: Chloroplasts also have an inner membrane system, but their folds are organized into structures called 'thylakoids'.
Recognize the role of thylakoids: In chloroplasts, thylakoids are stacked into structures called 'grana', which are involved in the light-dependent reactions of photosynthesis.
Identify the correct term for mitochondrial folds: Given the options, 'cristae' is the correct term for the folds in the inner membrane of mitochondria, distinguishing them from thylakoids and grana in chloroplasts.
