Question

Which type of permanent tissue helps in storing food in plants?
a) Parenchyma
b) Collenchymas
c) Xylem
d) Phloem

Answer 1

Hint: Permanent tissues are kinds of tissues that do not bifurcate further and they are distinguished on the basis of functions the tissue performs. Here in the question they are asking about the type of permanent tissue that will help in the storage of food in plants.

Complete answer:
Plant has a variety of tissues in it. So if we talk about the permanent tissue, it is that kind of tissue which does not divide further.
Parenchyma is a kind of simple permanent tissue. It has non-specialized cells located within its thin cell walls. The cells in the parenchyma tissue are loosely packed. This is the kind of tissue that helps in the storage of food and also provides support to the plants. It forms a great part of ground tissues in plants, where other tissues like vascular tissues are embedded. Now, if we see the options one by one:
Parenchyma is the one which helps in storage of food in plants. Therefore, this is the correct option.
Collenchymas is the kind of tissue that is made up of elongated cells and it provides support, structure, mechanical strength and flexibility to the various parts of the plants. It has no role in the storage of food. Therefore, it is an incorrect answer.
Xylem is a kind of vascular tissue that helps in the transportation of water and minerals from the root to the various parts of the plant. It does not have any role in the storage of food. Therefore, it is an incorrect option.
Phloem is also a type of vascular tissue that helps in the translocation of food from the site of generation to the various parts of the plants and also has no role in the storage of food. Therefore, it is also an incorrect option.

Hence, the correct answer is Option (a).

Note:
Plants have majorly three types of tissues which are ground tissue, vascular tissue and dermal tissue. The parenchyma cells are alive and polygonal in shape having a big central vacuole with intercellular spaces in between them. Parenchyma cells together form ground tissue and pith. If it contains chloroplasts then they are known as chlorenchyma.
