There are three types of meristems on the basis of position, i.e
Apical meristem.
Lateral meristem.
Intercalary meristem.
<h2>Explanation:</h2>
A meristem is the tissue present in most plants containing undifferentiatedcells, found in zones of the plant where growth can take place. Generally differentiated cells(the cells other than meristems) do not divide and produce of a different type of cells.
Meristems are classified on the basis of their location in the plant:
Apical meristem - these are the meristems located at root and shoot tips of the plant.
Lateral meristem - these are the meristems located in the vascular and cork cambia in plants.
Intercalary meristems - these are the meristems located at internodes, or stem regions between the places at which leaves attach, and leaf bases.
The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream.
The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.
so correct option is D) The lac operon will function normally.
