Ans 1: Biodiversity:
Biodersity is defined as The variety of living organisms on Earh.
Ans 2: Classification :
The grouping of organisms is called classification
Ans 3: Taxonomy:
Taxonomy is the brach of biology concerned with identficiation, naming and classification of organisms.

iv.Fungi have chitin in their cell walls.
v. Fungi have absorptive mode of nutrition
Examples:
Black bread mold, yeast,mushroom etc.
Ans 2: Plants:
i. Eukaryotic organisms.
ii. Kulti cellular

iv. Plants cell wall is made of cellulose
v. Plants have photosynthesic mode of nutrition.
Exaple: Moss, mustard

Question # 7

What are the basic difference between archaea and bacteria.

Ans 1: Archaeai. These are the most primitive organismsm on Earthii. They are prokaryotes but their cell wall does not contain peptidoglycan. The r RNA is mroe closely related to eukaryotes than to baceteria.iii. Their cell memberane contains unique lipids which enable them to live in extreme environments e.g. hot springs, slat, lakes, deep-sea hydrothermal vents, and acidic or alkaline waters,However, they also exist in more common environments like soil and oceans.iv. Some archeae obtain energy from inorganic compounds such as sulphur or ammonia. Othe rgroups perform photosynthesis but do not produce oxygen.iv.
Ans 2: Bacteria:i. They are teh true bacteria, They are unicellular, Many live solitary althought some form chains, clusters, or colonies of cellsii. They are also prokaryotic and hae cell wall made of peptidoglycaniii. Bacteria are found everywhere including soil, wate, air, and living organisms,.iv. Most are heterotrophic but some perform photosynthesis because they have chlorophyll.
Ans 3:

Question # 8

What were the shortcomign of three kingdom classfication system.

Ans 1: i. Some taxonomists disagreed about athe positio of fungi in kingdom planatae
ii. Fungi resemble platns in many ways but ar eheterotrophs Which get their food by absorption
iii. They do not have cellulose in their cell wall but posses chitin

Question # 9

How is he biodiversity crucial for humans and for the planet Earth.

Ans 1: Biodiversity provides many essentil services for humans and the planet. Here are some key benefits of biodiversity
Ans 2: 1. Ecosystem Stability: Biodiversity helps maintain the balance of ecosystems by contributing to the biogeochemical cycle.such as water cycle , carbon cycle, and nitrogen cycle.

Ans 4: Natural Resources: Biodiversity provides a vast array of resources form food and medicine to building materials and fuel
Ans 5: 4. Economic Benefits: Biodiversity supports numerious industire,s including agriculture tourism and pharmaceuticals
