The evaporation of water from the leaves of the plants is called transpiration. It is the process of water movement through a plant and its evaporation from aerial parts, such as from leaves but also from stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 99 - 99.5% is lost by transpiration. Leaf surfaces are dotted with pores called stomata, and in most plants they are more numerous on the undersides of the foliage.

It is a chemical reaction in which you mix two solutions of two ionic substances and a solid ionic substance (a precipitate) forms.
For example, precipitation occurs when a part of the atmosphere saturates itself with water vapour and when the right temperature comes its condenses and precipitates. The two processes which make the air saturated are the cooling of air molecules and the addition of water vapour.

a. Gold is used to make jewelry because of the attractiveness of its luster and because of its rarity. It also doesn't tarnish and doesn't react with air the way a metal like iron does. Gold is malleable, which means it can be beaten into very thin sheets. It's also ductile, which means it can be stretched out into thin wire as in the findings of earrings.
b. Different types of wood is used for making furniture (both hardwood and softwood) because of its strength and durability, color, density, grain, and finishing.
c. Glass is used to make window because it is the cheapest material that light passes through readily. The basic function of a window is to allow light into a building.
d. Coins that are intended for circulation have some special requirements based on the conditions they will encounter. For example, a coin may be in circulation for up to 30 years, and so must have excellent wear resistance and anti-corrosion properties. Achieving this goal necessitates the use of base metal alloys.

Classification of plants
1) Based on the size, nature of the stem and the life span, plants are classified into herbs, shrubs and trees There is one more category called as creepers and climbers.
a) A herb is a non-woody plant that has green and tender stem with few branches on. It is usually short. It has a very short life.
- Mustard, Tulsi, Wheat, Gram are some of the herbs we know.
b) A shrub is taller than a herb and has stem branching out at its base. Shrub is a bushy plant. The stems of a shrub are not hard but thick.
- Sunflower, Rose, Lime are some of the shrubs that we see around.
c) A tree is a woody plant that has many branches on a single stem. Trees serve us lot of benefits. Trees are with long life span.
- Mango tree, Neem tree, Peepal tree are some of the trees in our surroundings.
d) Creepers are the plants with weak stems and hence cannot stand straight. They grow on the ground. Creepers as the name suggests creep horizontally on the ground. Life time of creepers if very short.
e) Climbers are the plants that need support from other structures to grow and spread. Climbers can either grow horizontally or vertically unlike creepers that grow only in horizontal direction. Lifespan is very short in climbers.
2) Depending on the presence of flowers, plants are classified into two types namely, flowering plants and non-flowering plants.
a) Flowering plants are the plants which possess distinct roots, stems, flowers and fruits. e.g. Mango, Papaya, Guava.
b) Non-flowering plants are the plants which do not have distinct roots, stem, leaves, flowers or fruits. e.g. Fern, Moss.
3) Depending on the way they obtain food, plants are classified into autotrophs and heterotrophs.
a) Autotrophs are the plants which make their own food by the process of photosynthesis by using raw materials like carbon dioxide and water. e.g. Most of the green plants.
b)Heterotrophs are the plants which depend on other organisms for their food. e.g. Insectivorous plants.

Transpiration is the evaporation of water into the atmosphere from the leaves and stems of plants. Mainly it occurs at the leaves while their stomata are open for the passage of CO2 and O2 during the process of photosynthesis.
