Golden rice is enriched with
AGolden rice is a variety of rice (Oryza sativa)
produced through genetic engineering to biosynthesize beta-carotene, a precursor
of vitamin A, in the edible parts of rice. The research was conducted with the goal of
producing a fortified food to be grown and consumed in areas with a shortage of dietary
vitamin A, a deficiency which is estimated to kill 670,000 children under the age of 5 each

Where the deficiency symptoms of boron an calcium is observed in growing plants?
Plants were grown hydroponically to characterize the deficiency symptoms caused by the
absence of calcium (Ca) or boron (B). Primary symptoms occurred on the youngest tissue
for both elements, but distinct differences between Ca and B deficiencies were observed.
Plants responding to Ca deficiency exhibited discoloration and upward rolling of leaves and
ultimately necrosis. Plants responding to B deficiency exhibited minor chlorosis, upward
curling, and thickening of leaves, distorted meristems, and strap-like leaves.
Plants exhibiting an initial deficiency had leaves that had some bronzing on the margins of
older leaves and younger leaves were curled and necrotic on the edges (Fig. 3A). The
bronzing color was more pronounced on plants with moderate symptoms and necrosis was
more pronounced on younger leaves. Plants with advanced symptoms had fewer leaves and
bronzing on older leaves and younger leaves were completely necrotic

In which organ of the human body, lymphocyte cells formed?
Lymphocytes are the cells that determine the specificity of the immune response to
infectious microorganisms and other foreign substances. In humans lymphocytes
make up 25 to 33% of the total number of leukocytes. They are found in central
lymphoid organs and tissues such as the spleen, tonsils and lymph nodes and large
Assertion (A): Fatty acids should be a part of the balanced human dietReason
(R): The cells of the human body can not synthesize any fatty acids
The assertion is true because a balanced diet is a diet that contains the correct amount of carbohydrates, proteins, and fats. But the reason is false because human body cells synthesize various fatty acids except for iinoleic and linolenic fatty acids.
Consider the following statements:
1. Femur is the longest bone in the human body
2. Cholera is a disease caused by bacteria
3. 'Athlete's foot' is a disease caused by virus Which of the statements given above are correct?
i. The largest bone in human body is femur. ii. Cholera is caused by a bacteria Vibrio cholerae, iii. Athlete's foot disease is caused by parasific fungus of genus Trichophyton.
Apple belongs to the family
Rosaceae (the rose family) is a medium-sized family of flowering plants,
including about 2830 species in 95 genera. The name is derived from the type
genus Rosa. Among the most species-rich genera are Alchemilla (270), Sorbus
(260), Crataegus (260), Cotoneaster (260), Rubus (250), and Prunus (plums,
cherries, peaches, apricots, and almonds) with about 200 species. However, all of
these numbers should be seen as estimates - much taxonomic work remains.
Rosaceae includes herbs, shrubs and trees. Most species are deciduous, but some
are evergreen. They have a worldwide range, but are most diverse in the Northern
Several economically important products come from the Rosaceae, including many
edible fruits (such as apples, pears, quinces, apricots, plums, cherries, peaches,
raspberries, loquats, and strawberries), almonds, and ornamental trees and shrubs
(such as roses, meadowsweets, photinias, firethorns, rowans, and hawthorns)
The building block of cellulose is
Cellulose is an organic compound with the formula (C6H10O5) n,
a polysaccharide consisting of a linear chain of several hundred to many thousands
of (1 4) linked D-glucose units. Cellulose is an important structural component of the
primary cell wall of green plants, many forms of algae and the oomycetes. Some species
of bacteria secrete it to form biofilms Cellulose is the most abundant organic polymer on
Earth.The cellulose content of cotton fiber is 90%, that of wood is 40
