Which of the following cells are found in the roots, leaves and stems of plants?

Parenchyma cells are the most common and versatile type of plant cells found in various plant tissues, including roots, leaves, and stems. They are characterized by their thin cell walls and large central vacuoles, which allow them to serve multiple functions such as storage, photosynthesis, and tissue repair.

One of the key reasons parenchyma cells are prevalent in all these organs is their role in metabolic processes. In leaves, they are primarily involved in photosynthesis, particularly within the palisade and spongy mesophyll layers. In roots, they often store starches and other nutrients, while in stems, they contribute to the storage and transport of substances.

While collenchyma, xylem, and sclerenchyma cells play specific and important roles in structural support and transport, they do not have the same widespread presence across plant organs as parenchyma cells. Collenchyma cells are primarily found in young stems and petioles where flexibility is needed, xylem cells are specialized for water and nutrient transport and are mainly found in stems and roots, and sclerenchyma cells provide rigidity and are often present in mature tissues. Therefore, the unique versatility and presence of parenchyma cells
