… but with …. & …. ), …. (Flowering plants)

Answer 2

Land plants include Bryophytes (Mosses), Pteridophytes (Ferns), Gymnosperms (Woody plants without flowers but with seeds & cones), Angiosperms (Flowering plants)

Question 2

Plant diversity refered to the …. of wide …. of …. in their ….
It can also refer to …. among plants and …. observed within them.
There are around …. to …. species of ….. that exists on …

Answer 2

Plant diversity refered to the existence of wide variety of plant species in their natural environment.
It can also refer to differences among plants and variety of characters observed within them.
There are around 300,000 to 500,000 species of vascular plants that exists on Earth

Answer 6

R.H[Robert Harding] Whittaker (Dec. 27, 1920-Oct. 20, 1980), he gave the 5 kingdom classification for living organisms.
These 5 kingdoms were: Monera, Protista, Fungi, Plantae & Animalia
His categorization was based on multiple characteristics such as: Cellular Structure, Mode of Nutrition, Body Organisation, Reproduction, Phylogenetic Relationship

Question 7

Importance Of Plant Diversity

Based on knowledge availability
Based on structural make-up
Based on plant classification & taxonomy
Based on valuable characteristics

Answer 7

It makes available the knowledge of various forms of plants existing on Earth
It helps in understanding the simplicity and complexity of plants
It is very important in plant classification and taxonomical studies
The valuable characteristics of plants like life cycle, habits, their mode of nutrition and reproduction could be studied only by means of plant diversity

Question 8

Importance Of Plant Diversity

Based on evolutionary lines
Based on characters noting
Based on environmental correlation
Based on genetic diversity

Answer 8

We can trace evolutionary lines(primitive and advanced) in existing plants
Adaptive and progressive characters can be noted from plant diversity
It helps in understanding a correlation between the environment and the plants
It provides the understanding of genetic diversity: gene pool and levels of organisation of a particular plant’s species
