Question

Read the following statements w.r.t. meristematic cells:
(i) Cells have dense cytoplasm with prominent nucleus
(ii) Cells possess well developed mitochondria, plastids and endoplasmic reticulum
(iii) Cells posses the property to divided continuously
(iv) Apical meristems produce primary tissues
(v) During formation of leaves and elongation of stem, some cells left behind from shoot apical meristem, constitute the axillary bud
How many of the above statements are correct?

• A. Five
• B. Four
• C. Three
• D. Two

Answer 1

Answer: (B)

Four

Meristematic cells contain small, discrete mitochondria in the cell periphery and one large, mitochondrial mass in the perinuclear region.

The meristematic cell is the cell which is constantly divided so it contains dense cytoplasm with the prominent nucleus. They are rapidly dividing so the mitochondria, plastids and endoplasmic reticulum is not fully developed.

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.

So the correct option is ' four'.
