The heart is a muscle and it beats about seventy times per minute throughthout a person’s life. (Description)
The heart pumps blood from your heart to all parts of your body. The heart is made up of four chambers or small “rooms”. The top chamber are called the right and left auriclesand the botttom chambers are the right and left ventricles. (Description)
When blood enters the heart. It is in dark reddish color because it countains carbon dioxide. The blood enters the right auricle and then the right ventricle. When the heart contracts, it forces the blood to the lungs where the blood receives oxygen. It then goes to the left auricle. The heart contracts again, and the blood goes to the left ventricle and is then forced out into the body. The blood gathers carbon dioxide and returns to the heart, and the process begins again.

PLANT
Plants are living beings. They need food, water and air for survival. (General Classification)
Plants derive their food from the earth and the air. If you look at their roots, you will find that ends of these roots are like fine fibers. We call them root-hairs. They absorb water and minerals, then transport them upwards to the leaves through the trunk and the branches. It is the leaves which prepare the food. (Description)
The green material, chlorophyll, prepares the food like a machine. It converts the carbon dioxide taken from the air and water from the ground into sugar with the help of sunlight. This chemical reaction is called photosynthes. In fact, the chlorophyll takes energy from the sunlight and uses it to synthesize the hydrogen from water and carbon from carbon dioxide for making sugar. This reaction also gives out oxygen and water which are excreted by the leaves. (Description)
