EVERYDAY SCIENCE

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: -Cell division in plants occurs in regions called meristems . Cells of the meristem can differentiate to produce all types of plant cells at any time during the life of the plant. The main meristems are close to the tip of the shoot, and the tip of the root.

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.

Detailed explanation-5: -Hematopoietic Stem Cells (Blood Stem Cells) Mesenchymal Stem Cells. Neural Stem Cells. Epithelial Stem Cells. Skin Stem Cells.
