Forestry and Plant Sciences

Boreal forests, also known as taiga, are the world's largest terrestrial biome and are the primary source of softwood lumber and pulpwood for the global paper industry.

Forest structures like foliage, bark, and ground litter all contribute to slowing down water runoff. They help in absorbing water and reducing the kinetic energy of rainfall, which prevents soil erosion.

The canopy is the uppermost layer of the forest, formed by the crowns of the tallest trees. While 'crown' refers to the top of an individual tree, the collective top layer is the canopy.

• Turmeric has some antioxidant and anti-inflammatory properties and Basil is used for stomach spasms, loss of appetite, intestinal gas but they come under herbs, not a tree.
  
• Oak is mainly used for furniture purposes as Oak wood is exceedingly strong, heavy and durable.
  
• Neem tree has various medicinal properties such as antioxidant, anti-inflammatory, anti-diabetic, anticancer, antifungal, antiviral. 
• So, option A neem is the correct answer.
  

The forest floor is rich in organic matter, including humus formed by decaying leaves, and it supports various small plants like herbs that grow in the shade.

The crown of a tree is the collection of branches and leaves that extend from the main trunk.

The crown is the part of the tree that includes the branches and leaves, serving as the primary site for photosynthesis.

Pine trees are conifers with a characteristic conical shape, which helps them shed snow and survive in colder climates.

The canopy is the top layer of the forest, which is formed by the crowns of the tallest and most mature trees.

Both Sheesham (a hardwood) and Bamboo (a strong, versatile grass) are widely used in construction, furniture making, and various structural applications.

Dendrology is the scientific study of woody plants, specifically trees and shrubs.

Heartwood is also called as 'duramen'. It is dead, central wood of trees. Its cells usually contain tannins or other substances that make it dark in colour and sometimes aromatic. Heartwood is mechanically strong, resistant to decay and less easily penetrated by wood-preservative chemicals than other types of wood.

Urtica is a well-known example of a plant that exhibits anomalous secondary growth, specifically the presence of phloem or parenchyma islands within the wood.

Ochroma, commonly known as Balsa wood, is famous for having an extremely low density and specific gravity, often well below 0.2.

• Dalbergia is also known as African Blackwood.
• It is a flowering plant belonging to the family Fabaceae which are native to seasonally dry regions of Africa.
  
• It produces dense, lustrous wood which is reddish to pure black in colour.
• So, the correct answer is 'Dalbergia'.
