Plant roots are usually devoid of chlorophyll and cannot perform photosynthesis. However, there are exceptions. Which of the following plant root can perform photosynthesis?
1 Arabidopsis
2 Rice
3 Tinospora
4 Hibiscus
Explanation:
A Plant roots can perform the photosynthesis. As root hair cells do not carry out photosynthesis, they do not contain chloroplasts. Plants roots usually do not have chlorophyll but some epiphytic plants grow green and accumulate chlorophyll for photosynthesis. Arabidopsis is the dicot plant which develops the chloroplasts in roots.

The plant which bears clinging roots is:
1 trapa
2 orchid
3 screw pine
4 podostemon
Explanation:
B The clinging roots are non absorptive adventitious root arise from nodes or internodes. The plant which bears clinging roots is 'orchid'. Orchids are epiphytes, the clinging roots system, is present in them. Orchids live on the branches of trees so their roots are modified to absorb water from the atmosphere by hanging freely in the air.

Pneumatophores the respiratory root are characteristic feature of :
1 Avicennia
2 Sonneratia
3 Rhizophora
4 All of these
Explanation:
D Pneumatophores are also called respiratory roots. Pneumatophores are found in the vegetation which is found in marshy and saline lakes. The primary function of pneumatophores is to help plants to get the oxygen needed for the respiration process because the found at \(\mathrm{O}_{2}\) lack places. Here, Avicennia, Sonneratia and Rhizophora all of are the example of pneumatophores.

Stilt roots are reported from:
1 pandanus
2 radish
3 mango ginger
4 Bryophy/fum
Explanation:
A Stilt roots are reported from pandanus also known as screw pine. Stilt roots provide mechanical support to the plants. In pandanus the stilt roots develop only from the lower surface of the oblique stem to provide support. These roots are adventitious and often branched. Other examples of stilt root are maize, sugarcane.

Velamen-is found in:
1 Vanda
2 Rosa
3 Viscum
4 Santalum
Explanation:
A Velamen is found in 'vanda'. Velamen is a spongy tissue which is found in all epiphytic orchids and vanda. It is made up of multiple epidermis that covers the roots. Velamen is found in the aerial roots. It is helpful in absorption of moisture from atmosphere, also synthesis food in presence of chloroplast.
