8961.	Question : Various types of transport mechanisms are needed to fulfil the mineral requirements of a plant. Why are they not fulfilled by diffusion alone ?
Answer» SOLUTION :Various ions, mineral elements and for transport of organic substances, there are various methods in plants, like. (i) The food prepared by leaves is transported towards root and stem in lower direction. (ii) The food is transported towards developing leaves, buds and fruits. (iii) In stem, food is transported towards PULP, cortex and epidermis cross sectionally. (iv) Ions and mineral elements are transported upwards through xylem. Diffusion is a slow process and responsible for small distance transport of ions. It can not transport above mentioned organic and inorganic materials. So specific method is NECESSARY for transport of substances till long distance. e.g. MASS FLOW.

8987.	Question : Using appropriate examples, differentiate between false and true body segmentation.
Answer» Solution :Segmentation : It is the division of some animals and plant BODY parts into a series of repetitive segments. True SEGMENT : It is seen in some animals of Annelid, ARTHROPODA and Chordata. In that repetition of continuous body parts and each repetitive segment is called metamere. In earthwors, metamery is seen in series. But it is different in various segments of the body of fish and INSECT. In Annelida EXTERNAL and internal metamery is clear. Pseudo segment : When body is divided into many segments but each of them is independent of each other is called pseudo segment. Each segment is capable for doing all biological functions. The growth of the body is done by adding new segments from anterior side. eg. Tapeworm.
