Read the passage given below and answer the questions from [6] to [10]. |
The outermost layer of the cells is called epidermis. The epidermis is usually made of a single layer of cells. |
In some plants living in very dry habitats, epidermis may be thicker since protection against water loss is critical. |
The entire surface of a plant has an outer covering of epidermis. It protects all the parts of the plant. |
Epidermal cells on the aerial parts of the plant often secrete a waxy, water-resistant layer on their outer surface. That aids in protection against loss of water, mechanical injury and invasion by parasitic fungi. Since, it has a protective role to play, cells of epidermal tissue form a continuous layer without intercellular spaces. Most epidermal cells are relatively flat. Often their outer and side walls are thicker than the inner wall. Woody stems and structures like potato tubers, produce a second covering called periderm. |

Read the passage given below and answer the four questions from [11] to [15]. |
All living organisms need some method of moving substances from one part of the body to other parts of the body. Plants have a transport system to move things around. |
The xylem moves water and solutes from roots to leaves through transpiration. The phloem moves glucose and amino acids from the leaves to all parts of the plant through translocation. |
In modern plants, the xylem and phloem are arranged in groups called vascular bundles. The xylem is constituted by 4 elements, i.e. tracheids, vessels, parenchyma and fibres, while phloem is constituted by sieve tubes, companion cells, phloem fibres and parenchyma. |
In plants, the transport system is not as ....... as in animals.

Read the passage given below and answer the questions from [21] to [25]. |
In multicellular organisms, there are millions of cells. Most of these cells are specialised to perform a select few functions. Each specialised function is taken up by a different group of cells or tissues. Since, these cells of a tissue carry out only a particular function, they do it very efficiently. |
For example, in human beings, muscle cells contract and relax to cause movement, nerve cells carry messages and blood Hows to transport oxygen, food, hormones and waste materials and so on. |
Likewise, in plants, vascular tissues (xylem, phloem) conduct water and food from one part of the plant to other parts, meristematic tissues regulate normal growth and development, etc. |
Thus, it can be said that multicellular organisms show division of labour. |
Thus, cells are arranged and designed in a way so as to give the highest possible efficiency of the function they perform. |

I. Group of cells |
