Q.5 . Analogy based questions :

Find the relation in the first pair and accordingly fill in the blanks in second pair.

1. Collenchyma : pectin :: Sclerenchyma : _______
2. Bones : Mechanical support :: _________: Impulse conduction
3. Bacteria : prokaryote :: amoeba : ___________
4. eye piece : eye :: objective lens : __________
5. Meristem : growth :: Sclerenchyma : __________

Answers :

1. Collenchyma : pectin :: Sclerenchyma : lignin.

Collenchyma shows a compound cellulose called pectin that provides it with strength and structure. In the same way Sclerenchyma also shows a compound called lignin which is found in the thick and dead walls of the sclerenchyma cells.

2. Bones : mechanical support :: Nerves : impulse conduction.

Bones provide stucture and support to the body ; neurons the parts of nerves carry impulses.

3. Bacteria : prokaryote :: amoeba : eukaryotes

Bacteria is considered to be prokaryote i.e doesn't have a well defined nucleus while amoeba a eukaryote has a well defined nucleus.

4. Eye piece : eye :: objective lens : mirror

In an eye piece the observation is done by eye and in objective lens ; through a mirror.

5. Meristem : growth :: Sclerenchyma : structural support

Meristematic tissues are the tissues that keep growing ; Sclerenchyma is a type of permanent tissues meaning the ones which have stopped growing. The main function of Sclerenchyma is to provide structural support to the plant.
