Anatomy of Dicot root (gram)

The plants whose seeds have only one cotyledon are called dicots. The structure of dicot root varies greatly from that of the monocots. By understanding the structure of dicot root and monocot root, we can make comparisons between them and distinguish them by studying them under a microscope.

Meristematic Tissues

Growth in plants happens in two stages

  • first new cells are produced,
  • secondly these cells expand via uptake of water by the vacuole.

The division of cells doesn't occur throughout the plant - but only in meristematic regions. Expansion, however, can occur anywhere. Thus, in any plant, there are regions containing young cells, maturing cells and matured cells that have lost the capacity to divide.

Understanding Blood Groups & Its Inheritance

Blood caries many chemicals, which have various functions. One group of chemicals is called antigens, which can stimulate the production of antibodies. Based on the presence or absence of blood antigens and antibodies, four groups A, B, AB and O are recognized in human body. Antigens are the proteins on the surface of red blood cells. Blood of one group contains antibodies in the plasma that reacts against the antigen on the cells of other groups.
