Study of wood is called as
A) Dendrochronology
B) Morphology
C) Histology
D) Xylology

Hint: The branch of dendrology that deals with small structures of wood. Wood is a porous and fibrous tissue in the stems and roots of trees. Wood is also called secondary xylem.

Complete Answer:
In a living tree it gives support, conveys water and nutrients between leaves, tissues and the roots. It consists of cells and cell walls which contain microfibrils of cellulose (40-50%) and hemicelluloses (15-25%).

The correct answer is Xylology.

Uses:
- Used for fuel, as a construction material, making paper, weapons, furniture, tools etc.
- Feedstock for production of cellulose and its various derivatives like cellophane, cellulose acetate.
- Water content present in the wood. Water present in three locations:
- In the cell walls.
- In the protoplasmic contents of the cells.
- In the cavities and spaces of cells, especially of the xylem.

Types of wood:
A) Softwood
B) Hardwood
C) Ring-porous wood
D) Diffuse-porous wood
E) Monocot wood

Additional information: Morphology is the study of shape and structure.
Histology which is also known as microanatomy or microscopic anatomy is a branch of science which studies the microscopic anatomy of biological tissues.

Note: Dendrochronology (tree dating) is a method of dating tree rings to know the year when they were formed. By doing this the study of climate and atmospheric conditions during different periods can also be done.
