Question

Which of the following is a plant tissue that constantly undergoes mitosis?
A) Pith
B) Xylem
C) Phloem
D) Cortex
E) Cambium

Answer 1

Hint: Meristem is the plant tissue that is made up of undifferentiated or totipotent cells, that are capable of dividing and differentiating themselves continuously. It is located on the tip of the stem cells and roots which allows plant stems and roots to grow longer and wider.

Complete answer:
To answer this question you must know about the part of the plant which undergoes mitosis.
All living things have different and specialized cells to perform different functions essential for living organisms. Plants have a tissue called cambium tissue which is not specialized, but it is essential that meristem cells are equivalent to human stem cells. It is found in the area between the xylem and phloem of the plant and it divides and differentiates continuously by the process of mitosis to create new stems and roots.


Pith is the type of plant tissue that is located in a plant’s stem and roots. It is soft and spongy to help to transport the nutrients throughout the plant and storing nutrients within cells.
Xylem is a type of vascular tissue which helps in the uptake and distribution of water and minerals are taken up by roots to different parts of the plant.
Phloem is also a type of vascular tissue in plant plants responsible for the distribution of sugars and nutrients manufactured in shoots.
The outermost layer of cells on a plant’s stem or roots is known as the cortex. It has the ability to transport nutrients into the core of roots.

In the given question out of them, all options only cambium tissue constantly undergoes mitosis therefore the correct option of the given question is (E) cambium.

Note: The first fossils that show the presence of vascular tissue date to the Silurian period, about 430 million years ago. Mitosis is the process that occurs during the formation of body cells. It occurs in some specific regions like skin and bone marrow in animals and meristem in plants that help to create secondary xylem and secondary phloem.
