Concept explainers
Interpretation:
The component that does not belong to the chloroplast should be chosen.
Concept introduction:
Chloroplasts produce food for the plants by conversion of the light energy to sugars which can be utilized by the plants. There are two membranes that contain and protect the inner parts of chloroplast, the inner and the outer membrane.
Answer to Problem 1P
The correct answer is option (c) Cristae.
Explanation of Solution
Reason for the correct answer:
Option (c) Cristae. It is a fold in the inner membrane of a mitochondrion. The name is from the Latin for crest or plume, and it gives the inner membrane its characteristic wrinkled shape, providing a large amount of surface area for
Reason for incorrect answer:
Option (a) Thylakoid membrane: The thylakoid system is suspended in the stroma. The thylakoid system is a collection of membranous sacks called thylakoids. The chlorophyll is found in the thylakoids and is the sight for the process of light reactions of photosynthesis to happen. So, this is an incorrect option.
Option (b) Stromal lamellae: The inner membrane of the chloroplast forms a border to the stroma. It regulates passage of materials in and out of the chloroplast. In addition of regulation activity, the fatty acids, lipids and carotenoids are synthesized in the inner chloroplast membrane. So, this is an incorrect option.
Option (d) Granum: The thylakoids are arranged in stacks known as granum. Each granum contains around 10-20 thylakoids. So, this is an incorrect option.

These are photosynthetic pigments efficient at absorbing orange, red, yellow, and green light, wavelengths that are not well absorbed by chlorophyll a? TRUE OR FALSE A coupled reaction is a pair of reactions, one exothermic and one endothermic. ATP contains less energy than ADP. In the ATP-ADP cycle, when the phosphate is removed, energy is released. In coupled reaction, an endothermic reaction supplies the energy needed to drive an exothermic reaction. Chlorophyll absorbs green light.arrow_forwardIt is biochemical reactions that enable organisms to harness sunlight to manufacture organic molecules?
