When a seed gets proper air, water and warmth (sunlight), it germinates to form a new plant. Stages of Germination : The seed absorbs water from the soil. As a result, the seed coat becomes soft. It breaks up and the baby root or radicle comes out. It develops and goes deep into the soil. Then the baby shoot or the plumule emerges that develops and grows towards the sunlight. The new baby plant that has a small root and a small shoot is called a seedling. The seedling uses the food stored in cotyledons for its growth. Gradually, the shoot grows and tiny foilage leaves appear on it. When the foilage leaves grow, they start preparing their own food by the process of photosynthesis. The new plants produces flowers which grow into fruits. Fruits contain seeds. Under suitable conditions of air, water and warmth, these seeds germinate and grow into new plants. In this way, the cycle of reproduction continues."],"difficulty":"E","outcome":"book","mark":"1","question":{"title":"Answer the following questions :bsp;&nbsp;<i><i>","option":["What is germination?

The process by which seeds get scattered away from the mother plant is called dispersal. Let us learn about the different ways by which seeds get dispersed. By Wind: The wind carries away many small seeds that are very light and have wing-like structures. The seeds thus get scattered. For example, the dandelion and sycamore fruits are light and have extensions which acts as parachutes or wings to catch the wind. The light and hairy cotton seed also gets dispersed by wind. By Water: The seeds of some plants, such as coconut and lotus, get dropped into or near water bodies. The fibrous coverings of these seeds help them float away and germinate at a different place. By Animals: Some seeds such as cocklebur have sticky or prickly seed coats that stick to the fur of animals. These seeds are carried by animals from one place to another, and get dropped on the ground later. Seeds are also dispersed by birds and other animals that eat fruits. The undigested seeds pass through their bodies and often end up far from where the birds ate the fruits. By Explosion: Some fruits scatter their seeds by exploding. The pod ripens bursts open and forcibly shoots the seeds in all directions. Poppy, pea and bean seeds get dispersed by explosion."],"difficulty":"E","outcome":"book","mark":"1","question":{"title":"Answer the following questions :bsp;&nbsp;<i><i>","option":["What are the various methods of seed dispersal?

They pile up in thick layers on the bottom of the water bodies. Over a long period of time, the pieces become pressed together and form solid rock called sedimentary rock.

We get metals like iron, aluminium, copper and zinc respectively from these ores. Gold, silver and plantinum metals are used for making jewellery. Non-Metallic Minerals: Some minerals do not have metals in them. So they are called non-metallic minerals. Many of the minerals are in the form of crystals. They are very hard.

They are made up of the round end of one bone (ball) fitting into a small cup-like area (socket) of another bone. The Pivot Joint: These joints allow parts of our body to turn. A pivot joint is found between the skull and the first two vertebrae of the spine. It allows us to move our head sideways, upwards and downwards. Pivot joints also provide the twisting movement of the bones of the forearm against the upper arm The Gliding Joint: Gliding joints occur between the surfaces of two flat bones that are held together by ligaments.

For white light, the shadow is always black in colour. The shadow formed is just the outline of the obstacle.
