Match the names of the structures given in column-I with the functions given in column-II, choose the answer which gives the correct combination of the two columns :

Column-I	Column-II
(Structure)	(Function)
A. Stomata	I. Protection of stem
B. Bark	II. Plant movement
C. Cambium	III. Secondary growth
D. Cuticle	IV. Transpiration
V. Prevent the loss of water	...

Correct Answer : D.

A - Stomata: They are minute aperture structures on plants found typically on the outer leaf skin layer, also known as the epidermis. They consist of two specialized cells, called guard cells that surround a tiny pore called a stoma. It helps in transpiration and gaseous exchange. Transpiration is the transport of water through an actual, vegetated plant into the atmosphere. Transpiration is an important part of the evapotranspiration process, and a major mechanism of the water cycle in the atmosphere.
B - Bark: Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside of the vascular cambium. It serves as protection of stem against damage from parasites, herbivorous animals and diseases, as well as dehydration and fire.
C - Cambium: It is a cellular plant tissue from which phloem, xylem, or cork grows by division, resulting (in woody plants) in secondary thickening.
D - Cuticle: It is a protecting film covering the epidermis of leaves, young shoots and other aerial plant organs without periderm. It consists of lipid and hydrocarbon polymers impregnated with wax, and are synthesized exclusively by the epidermal cells. In addition to its function as permeability barrier for water and other molecules (prevent water loss), the micro and nano-structure of the cuticle confer specialised surface properties that prevent contamination of plant tissues with external water, dirt and microorganisms.
