Summary Introduction
To define and arrange:
The terms “chloroplast, thylakoid membrane, photosystem, reaction center, and granum” from smallest to largest.
Concept introduction:
The process of photosynthesis takes place inside the chloroplast of the plant cells. This is the reason chloroplasts are referred as “kitchen of the plant cell”. Chloroplast contains grana and stroma. Grana are the place where the light reaction takes place, whereas stroma is the place where the dark reaction of photosynthesis takes place.

Students have asked these similar questions
Which of the following statements incorrectly describes the structure of a chloroplast?
A chloroplast has both an outer membrane and an inner membrane, often separated by a narrow intermembrane space.
The inner membrane of the chloroplast encloses the stoma, a dense fluid filled with enzymes needed for photosynthesis.
A chloroplast contains thylakoids, which are flat, saclike structures suspended in the stroma.
Thylakoids of a chloroplast are arranged into stacks called grana.
Match the number from the key below to each of the following processes, in order: chemiosmosis; fermentation; glucose synthesis; Krebs cycle.
KEY:
occurs in the chloroplast only
occurs in the mitochondrion only
occurs in both the chloroplast and mitochondrion
occurs in neither the chloroplast nor mitochondrion
Record your answer as a FOUR-digit answer,
Which of the following does NOT apply to chloroplasts?
They contain an internal membrane system consisting of thylakoids
They contain chlorophyll and the enzymes required for photosynthesis
They are bounded by two membranes, the inner of which is folded into the cristae
They synthesize ATP (adenosine triphosphate) from ADP (adenosine diphosphate) and Pi (inorganic phosphate)

- All of the following membranes or compartments can be found in a typical eukaryotic chloroplast, with the exception of: the outer chloroplast membrane the stroma the inner chloroplast membrane the matrix the thylakoid membranearrow_forwardChloroplasts are double membrane organelles with a smooth outer membrane and an inner membrane that is folded into disc-shaped sacs called the thylakoid. Color and label the outer membrane light green U. Color and label the inner membrane brown U. Thylakoids contain chlorophyll and other pigments (red, orange, yellow, brown) and are found in stacks called granum (grana, plural.) Color and label the thylakoids dark green O, then highlight the entire stack of granum with yellow U. These stacks are connected to other stacks by channels called lamellae. Color and label the lamella orange. Grana are surrounded by a gel-like material called stroma. Color and label the stroma blue. 11. How many membranes surround a chloroplast? 12.
