The most thoroughly studied of the known bacteria-plant interactions is the
1 cyanobacterial symbiosis with some aquatic ferns
2 gall formation on certain angiosperms by Agrobacterium
3 nodulation of Sesbania stems by nitrogen fixing bacteria
4 plant growth stimulation by phosphate solubilizing bacteria
Explanation:
There are several types of plant microbe interactions such as, competition, Commensalism, Mutualism, Parasitism. Plants and bacteria do interact with one another in a variety of ways. The agrobacterium crown gall phenomenon is to date the most thoroughly studied and best documented of the known bacteria-plant interactions. This bacterium contains a large Ti plasmid which is extensively used as natural genetic engineer in plant genetic engineering.

Rarely among angiosperms the pollen grains influenced the endosperm. This is called as
1 metaxenia
2 nemec phenomenon
3 xenia
4 mesogamy
Explanation:
The classical example of pollen grain influence of endosperm can be seen in maize commonly known as mays. The transfer of character by a male gametes and its influence on endosperm is known as xenia. - The term xenia was originally coined to refer direct effect of pollens on seed and fruit characters or effect of gene from male parent on development of fruit and seed.

Which of the following is a saprophytic angiosperm?
1 Agaricus
2 Cuscuta
3 Neottia
4 Eucalyptus
Explanation:
The plants belonging to genus Neottia lack leaves and chlorophyll and obtain their nutrition from fungi or by Saprophytic nutrition. - Saprophytes cannot produce their own food as autotrophs, where as heterotrophs cannot produce or manufacture their own food.

A plant which lives on another plant but do not take food or anything from plant is called:
1 endophyte
2 epiphyte
3 parasite
4 host
Explanation:
Epiphytes are those plants which are attached to another plant but do not grow parasitically upon it merely uses it for support. - Epiphytes have no attachment to the ground or other obvious nutrient source and are not parasitic on the supporting plants. Example- Orchids, mosses etc.
