What distinguishes chlorenchyma tissue from other types of parenchyma?

Chlorenchyma tissue is characterized by its ability to perform photosynthesis, which is primarily due to the presence of chloroplasts within its cells. This unique feature distinguishes chlorenchyma from other types of parenchyma, which typically lack chloroplasts and are not involved in photosynthesis. While other parenchyma tissues may serve various functions such as storage or transportation, chlorenchyma specifically facilitates the conversion of light energy into chemical energy through the photosynthetic process, thus playing a crucial role in plant metabolism and energy production.

Other features often found in parenchyma, such as thick cell walls or being dead at maturity, do not apply to chlorenchyma. Moreover, the presence of high intercellular spaces is more related to aerenchyma, a specialized type of parenchyma that allows for gas exchange rather than the photosynthetic function of chlorenchyma. Consequently, the role of chloroplasts in chlorenchyma is what primarily sets it apart, making option B the distinguishing characteristic.
