1. Read the following passage carefully and answer the questions that follow:
When a seed is grown in the soil, it takes only water and gels ruptured. Two parts come out of it, plumule and radical above and below the surface respectively. At start, both the parts grow almost at the same pace. Then routs take water and other minerals from the soil and shoots grow. The shoots grow upward while the roots grow downward. Initially, the shoots take essential elements from the soil and send it to the shoots, shoots start showing leaves which in turn form food and send to the whole body of the plant. Plants prepare their food in the presence of sunlight, water and carbon dioxide through the process of photosynthesis. Once this process starts, the plant continues to produce oxygen (O2) and energy in the form of glucose (sugar). This oxygen is no doubt a vital breath (Pranvayu) for human beings. That is why it is continuously requested to save plants and grow more and more in our vicinity. So, for growing trees we must save seeds also. Today onwards whenever you eat any fruit or vegetable think about saving seeds also. Dry them or let them dry and grow or let them grow in favourable conditions.
