• It is a natural process in which the body removes old, damaged, or unwanted cells in a controlled manner.
• Apoptosis plays an important role in embryonic development, such as removing the cells between developing fingers and toes.
• This process helps maintain healthy tissues and prevents damaged cells from surviving unnecessarily.

Explanation

• The secondary cell wall develops between the plasma membrane and the primary cell wall after the cell has stopped or largely completed its expansion.
• It is deposited on the inner side of the primary cell wall.
• It often contains cellulose, hemicellulose, and lignin.
• Lignin makes the secondary cell wall stronger and more rigid, providing mechanical support to the plant.

Explanation

Passage: A serious critic has to comprehend the particular content, unique structure, and special meaning of a work of art. And here she faces a dilemma. The critic must recognize the artistic element of uniqueness that requires subjective reaction; yet she must not be unduly prejudiced by such reactions. Her likes and dislikes are less important than what the work itself communicates, and her preferences may blind her to certain qualities of the work and thereby prevent an adequate understanding of it. Hence, it is necessary that a critic develop a sensibility informed by familiarity with the history of art and aesthetic theory. On the other hand, it is insufficient to treat the artwork solely historically, in relation to a fixed set of ideas or values. 

According to the author, a serious art critic may avoid being prejudiced by her subjective reactions if she? Brings to her observation a knowledge of art history and aesthetic theory

The author implies that it is insufficient to treat a work of art solely historically because? Doing so can blind the critic to some of the artwork's unique qualities
