NCERT Solutions for class 9 Chapter-06 Tissues: The chapter on Tissues is important for students approaching the home exams. This article introduces NCERT solutions designed to help students explain the concepts of further learning and how to write to get good grades on exams. The solutions are presented in very simple language for ease of understanding.

NCERT CBSE Chapter 06 Tissues of Class 9 explain a group of cells that possess similar structures and perform a specific function. In some simple multicellular organisms e.g. sponges, there is a devoid of tissues or if present, poorly differentiated. Multicellular organisms that are highly advanced have specialized tissues. Tissues give shape to the body and help it in the conservation of heat and store energy. Revise the basic concepts of Tissues for quick revision and class notes.

Q1: Name the types of simple tissues.

Answer:

Simple tissues are the tissues that are made up of only a single type of cell that looks similar to each other. There are three types of simple tissues i.e. parenchyma, collenchyma, and sclerenchyma.

Q2: Where is apical meristem found?

Answer:

The apical meristem is present at the growing tips of roots and shoots. It is responsible for root and shoots development.

Q3: Which tissue makes up the husk of coconut?

Answer:

The coconut shell consists of sclerenchyma tissue. The sclerenchyma cells are stretched and dead. Their cell wall is made of lignin. They are found in the husks of seeds and nuts and in the veins of leaves. They guarantee mechanical support to the plant.
