Detailed explanation-1: -Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. The increase in length of the shoot and the root is referred to as primary growth. It is the result of cell division in the shoot apical meristem.

Detailed explanation-2: -Primary growth in shoots Just as in roots, primary growth in stems is a result of rapidly dividing cells in the apical meristems at the shoot tip. Subsequent cell elongation then leads to primary growth.

Detailed explanation-3: -This type of growth is known as indeterminate growth. Plants are able to do this because plants have special body tissue called meristems located primarily in the tips of roots, stems, and leaves of plants. Meristems are the tissues that control plant growth.

Detailed explanation-4: -Primary growth in stems In stems, primary growth occurs in the apical bud (the one on the tips of stems) and not in axillary buds (primary buds at locations of side branching). This results from apical dominance, which prevents the growth of axillary buds that form along the sides of branches and stems.

Detailed explanation-5: -primary growth. The lengthening of plant roots and shoots is called. become longer. During periods of primary growth at apical meristems, stems and roots.
