Primary growth or lengthening of plants results from mitotic division in cells of which tissue? a. axillary buds b. lateral meristem c. apical meristem
Apical meristem can be defined as the region having rapidly growing cells, at tips of plant shoot and roots.
It is responsible for primary growth of plant shoots and roots as division in cells of this region results in increase in length of plant shoot and roots.
This is because cells present in this region are actively involved in growth by undergoing mitotic cell division.
Thus, the correct answer is option C.
The correct option is C) Apical meristem
Apical meristem can be described as undifferentiated meristematic cells found in the tips of the shoots and roots. The main function of the apical meristem is to start the process of cell division at these parts. In the apical meristems, cells tend to grow by undergoing numerous mitotic divisions. As result, primary growth and lengthening of the plant occur. Hence, the correct option is option C.
Other options, like option B, is not correct because it is the site where secondary growth occurs.
