Question
Chapter 22, Problem 2STP
Summary Introduction
Introduction:
The leaves of plants are involved in photosynthesis and the structures of the leaves are such that it is well adapted to this function. The leaves have a flattened area that is termed as the blade. It is involved in providing a large surface area. The blades of the leaves are attached to the stem with the help of a stalk that is termed as petiole.
Expert Solution & Answer
Answer to Problem 2STP
Correct answer:
The correct answer is option (A).
Explanation of Solution
Explanation/justification for the correct answer:
Option (A) The picture represented in option A is of palisade mesophyll cells. This portion of the cell is highly exposed to the light; so, most of the photosynthesis process takes place in this cell. This cell has many chloroplasts; therefore, most of the photosynthesis process takes place in this part.So, the correct answer is option (A).
Explanation for incorrect answer:
Option (B)The picture represented in option B is of spongy mesophyll. It is found below the palisade layer spongy mesophyll tissue is found, which are rectangular, and loosely packed. The oxygen, water vapor, and carbon dioxide pass-through space. So, this is an incorrect option.
Option (C) The picture represented in option C is of an epidermal cell. This is the outermost part of a leaf that involve in the protection of plants from pathogens and environmental effects. So, this is an incorrect option.
Option (D) The picture represented in option D is of the cuticle. This is involved in the prevention of water loss in the plant. So, this is an incorrect answer.

Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature.
