Solution 5.a:

Differences between flowering and non-flowering plants:

s.no	Flowering plants	Non-flowering plants
1.	They bear flowers.	They do not bear flowers.
2.	The seeds are enclosed in fruits.	The seeds are naked.
3.	They have roots, stem and leaves.	They may not have roots, stem and leaves.
4.	Examples: Jasmine, datura	Examples: Fern, spirogyra

Solution 5.b:

S.no	Trees	Shrubs
1.	Plants which grow very tall and have strong, hard stems or trunks are called trees.	Plants of medium height with strong, hard stems are called shrubs.
2.	The branches in a tree appear higher up on the stem.	Shrubs tend to branch near the ground, and so, many branches are seen rising just above the ground.
3.	Examples: Mango, banyan	Examples: Earthworm, snail

Solution 5.c:

Differences between vertebrate and invertebrate animals:

S.no	Vertebrate animals	Invertebrate animals
1.	Animals which have a vertebral column are called vertebrate animals.	Animals which do not have a vertebral column are called invertebrate animals.
