Solution
The correct option is B Four
Meristematic tissues are cells or group of cells that have the ability to divide continuously. These tissues in a plant consist of small, densely packed cells that can keep dividing to form new cells.
Meristematic tissue is characterized by small cells with densely packed cytoplasm, thin cell walls, large cell nuclei, absent or small vacuoles, absence of reserve food material and no intercellular spaces. They are rapidly dividing cells so the mitochondria, plastids and endoplasmic reticulum is not fully developed in these cells.
Apical meristems, which are located at the tips of shoots and roots in all vascular plants, give rise to three types of primary meristems, which in turn produce the mature primary tissues of the plant. As the apical meristem grows and forms leaves, it leaves behind a region of meristematic cells at the node between the stem and the leaf which constitute the acillary bud.
Thus statements (i), (iii), (iv),and (v) are correct.
