Question

The second meristem originates from
A. Promeristem
B. Primary meristem
C. Permanent tissue
D. Secretory tissue

Answer 1

Hint: Plants have both dividing and non-dividing cells. Some lose their ability to differentiate after a certain point. They all help the plant to grow in every way. Root and shoots are the first ones to grow. Some plants keep on growing throughout their life.

Complete answer:
What is meristem? A tissue in plants which has undifferentiated cells which can perform cell division. Based on the origin and development, there are various groups-promeristem, primary meristem and secondary meristem. Primary develops from the promeristem whereas the secondary meristem will form secondary tissues from the permanent tissues.
Let us learn about the terms in the question.
Option A: Promeristem: These are the primary meristem cells which can actively divide. There are meristematic cells at the shoot and root tip of the plants.
Option B: Primary meristem: The tissue held responsible for the primary growth is primary meristem. They help in the growth of plants lengthwise, increasing the height of the plant.
Option C: Permanent tissue: These cells do not divide. They are modified to perform the function in plants. They originated from the meristematic cells. They are found in mature plants with parenchyma cells only. They are fixed now in the plants and have lost their ability to divide.
Option D: Secretory tissue: The tissue which will release gums, latex, oils etc. are secretory. They form the special tissues which make the by-products in the plants.

So the answer is option C: Permanent tissue.

Note:
 The tip of the apex is the undifferentiated area and has the undifferentiated meristematic cells. They trigger the growth of the young cells to form the buds. They also replace worn-out cells.
