Answer 2

NUTRITION IN PLANTS
Green plants are called producers or autotrophs,as they are capable of preparing their own food with the help of some non-living factors of the environment. Green plants take carbon dioxide from the air and water and minerals from the soil through the roots. The green-coloured pigment called chlorophyll present in the leaves of plants traps energy from the sunlight. This kind of nutrition in which green plants make their own food by utilising simple substances from the environment is called autotrophic nutrition. The process by which plants make their food is called photosynthesis (photo:light; synthesis :to combine).
During photosynthesis, the leaves containing chlorophyll, in the presence of sunlight, use carbon dioxide and water to synthesise glucose or suger (simple carbohydrates ).During this process, oxygen is realised by plants into atmosphere. Plants use some sugar for its growth and to repair the worn out cells. The glucose ultimately gets converted into starch (a complex carbohydrates )and is stored in different parts of the plant body. The starch is carried to various parts of plants through pipe like structures called phloem. The food stored in different parts of the plant are used by humans and animals.
