Sexual reproduction takes place in humans. Fertilization is the first step in sexual reproduction. When sperms come in contact with an egg, one of the sperms may fuse with the egg. Such fusion of the egg and the sperm is called fertilization. During fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus which results in the formation of a fertilized egg or zygote. It is due to fertilization that the new individual inherits some characteristics from the mother and some from the father.

- Parts of the Cell: There are three main components of a cell – cell membrane, cytoplasm and nucleus. The parts of a cell include cell membrane, nucleus, mitochondria, chloroplasts, cell wall and vacuoles.
i. Cell membrane - Every cell is covered by a thin sheet of skin called cell membrane or plasma membrane. The cytoplasm and nucleus are enclosed within the cell membrane. It is also called plasma membrane.
ii. Cell wall – The plant cells have a thick cell wall around them outside the cell membrane. It gives shape and support to the plant cells.
iii. Cytoplasm - The jelly-like substance between the nucleus and the cell membrane is called cytoplasm.
iv. Nucleus – Nucleus is a large spherical organelle present in the centre of the cell that controls all its activities.
v. Vacuole – The blank-looking structures in the cytoplasm are called vacuoles.
vi. Plastids – Plastids are small coloured bodies scattered in the cytoplasm of plant cells. They are of different colours. Chloroplasts are green coloured plastids that contain green pigment called chlorophyll which helps in photosynthesis.
vii. Mitochondria – Mitochondria are tiny rod-shaped or spherical-shaped organelles which provide energy for all the activities of the cell. It is also called the powerhouse of the cell.

Cell Structure
Basic cell contains:
1. Cell membrane
The outermost membrane of the cell is called as cell membrane.
2. Protoplasm
Everything that is present in the cell except cell membrane comes under protoplasm. Protoplasm is living material of cell. Or the entire content of living cells including cytoplasm and nucleus is known as protoplasm.
Protoplasm is further divided into two parts:
Cytoplasm
Nucleus
Mitochondria: It provides energy to the cell.
Golgi body: It packages, dispatches the cellular secretions.
Ribosomes: It is helpful in protein synthesis.

Metals |
Non-metals |
|
1. Metals are generally solid at room temperature. (Except Mercury) |
1. Non-metals exist in all the three states i.e solid liquid and gas. |
|
2. Metals are generally hard. (except sodium which can be cut using a knife) |
2. Non-metals are generally soft. (except diamond which us the hardest substance on the earth) |
|
3. Metals are Malleable; means can be converted into thinsheets using a hammer. (except sodium and potassium) |
3. Non-metals are generally brittle. Will broke down intopieces when beaten by a hammer. |
|
4. Metals are ductile, means they can be converted into thinwires. |
4. Non-metals are non ductile. |
|
5. Metals have shiny surface or they are lustrous. |
5. They are non lustrous. (except iodine) |
|
6. Metals can lose electrons so they are electropositive innature. |
6. Non-metals gain electrons so they are electronegative innature. |
|
7. Metals are good conductors of heat and electricity. |
7. Non-metals are bed conductors of heat and electricity.(Except graphite) |
|
8. Metals are sonorous. They produce a sound on striking witha hard surface. |
8. They does not do so they are not sonorous. |
|

Destructive Distillation of Coal
When a substance is heated in the absence of air, the process is called destructive distillation. It results in the decomposition of the substance, bearing carbon rich residue.
Destructive distillation of coal produces coke, coal tar, coal gas and ammonia solution.
