Various types of transport mechanisms are needed tofulfill the mineral requirements of a plant. Why are they not fulfilled by diffusion alone?

State various types of adventitious roots which are modified for mechanical support.

The televisions manufactured in a factory are stored in two warehouses. They are then transported to the two shops. In the month of January, the first warehouse has 45 televisions and the second warehouse has 55 televisions. The first shop requires 53 televisions and The second shop requires 47 televisions. The televisions are transported from each warehouse to each of the two shops. If the requirement of each shop is fulfilled then represent the above information in terms of one matrix equation. Further, the transportation charges per unit area are Rs. 100 and Rs. 150 for the first and second shop respectively and the total transportation charges for the two warehouses are Rs. 10000 and Rs. 15000 respectively. Represent this information in terms of one matrix equation.

The minerals absorbed by the roots travel up the xylem. How do they reach the parts where they are needed most? Do all the parts of the plant get the same amount of the minerals?

Explain the mechanism of mineral translocation in plants.

Which plant tissues are involved in transport of water and minerals?

Answer the following Read the paragraph and answer the questions given below it. A biotic carbon atoms are circulated into the biotic form through processes like photosynthesis and respiration. Green plants convert carbon dioxide into carbohydrates and also produce carbon compounds like proteins and fats. Biotic compounds are transported from plants to apex consumers through intermediate trophic levels. After the death of all types of consumers, carbon is recycled by biotic decomposition. The carbon recycled in this way goes into the atmosphere and can be taken up by living organisms thus ensuring circulation and recycling of carbon in the biosphere. By which process do green plants convert atmospheric carbon into carbohydrates?
