Which one of the following is/are components of conducting tissue in plants? 1. Xylem 2. Phloem 3. Pericycle Select the correct answer using the code given below: Correct Answer 1 and 2 only

The correct answer is 1 and 2 only.

Key Points

  • Pericycle
    • It is a cylinder in the sclerenchyma or parenchyma cells lying inside of the endodermis, which is the outermost part of stele in the plants. 
    • Its functions include providing protection to vascular bundles and strengthening the roots.
    • Tracheids are a part of the xylem as elongated cells, that help in the transport of mineral salts and water.
    • Sieve Tubes are elongated cells in the phloem which help in the conduit of food transport, mostly sugar.
    • Fibres are elongated cells that help in providing support to the plant.
  • Xylem
    • It is conducting tissue found in plants that are known for the function of transport of water and some important mineral ions from the soil via roots to the other aerial parts of the plant I.e. stem and leaves.
    • This type of flow from roots to other parts of the plant is known as unidirectional flow.
  • Phloem
    • It is a conducting tissue that is known to transport food material from leaves which are formed via the process of photosynthesis to the other parts of the plants.
    • This type of transport of food materials via phloem is bidirectional.
  • Hence, Option 1 is correct.

A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?
