NEET BIOLOGY

Detailed explanation-1: -These in turn have the potential to develop into any organ or tissue. Therefore, plant stem cells are termed as totipotent cells.

Detailed explanation-2: -Plant stem cells are innately undifferentiated cells located in the meristems of plants. Plant stem cells serve as the origin of plant vitality, as they maintain themselves while providing a steady supply of precursor cells to form differentiated tissues and organs in plants.

Detailed explanation-3: -In the center of the root meristem, a small group of cells called the quiescent center (blue) are surrounded by stem cells (red), whose descendants continue to divide for a while before differentiating into the various tissues that form the root.

Detailed explanation-4: -Meristems can also be found in the stem between the phloem cells and the xylem, we’ll learn more about these later in this unit. Meristems in the stem allows it to thicken to give the stem support as it grows. Meristems divide to form unspecialised cells which can then become any type of plant cell.
