✓
Answer
|
Simple tissue
|
Complex tissue
|
|
These tissues consist of only one type of cells.
|
These tissues are made up of more than one type of cells.
|
|
The cells are more or less similar in structure and perform similar functions.
|
Different types of cells perform different functions. For example, in the xylem tissue, tracheids help in water transport, whereas parenchyma stores food.
|
|
Three types of simple tissues in plants are parenchyma, collenchyma, and sclerenchyma.
|
Two types of complex permanent tissues in plants are xylem and phloem.

There are three substances X, Y and Z. The substance X does not have a fixed melting point or boiling point and it still shows the individual properties of its constituents. The substance Y is a pure substance which occurs in nature as such. The substance Y has a fixed melting point and boiling point but it cannot be broken down into simpler substances by any chemical means. The substance Z is also a pure substance whose properties are entirely different from those of its constituents. The substance Z can, however, be divided by electrolysis into two substances which belong to the same class of substances as Y.
- What type of substance could X be? Name one substance like X.
- What type of substance could Y be? Name one substance like Y.
- What type of substance could Z be? Name one substance like Z.
- Whish process involves absorption or release of an appreciable amount of energy: formation of substance X or formation of substance Z?
- Name the three groups into which all the substances like Y are divided on the basis of their properties.
