✓

Answer

Differences between dorsiventral leaf and isobilateral leaf:
Dorsiventral LeafIsobilateral Leaf
The number of stomata is more on the abaxial epidermis than the adaxial epidermis.
Mesophyll is differentiated into spongy and palisade parenchyma.Vascular bundles are large and vary in size as per the size of veins.
Bulliform cells are absent.		Almost equal number of stomata is present on the abaxial and adaxial surfaces.
Mesophyll layer is not differentiated into spongy and palisade.Vascular bundles are similar in size, only the bundles near the mid vein are vary.
Bulliform cells are present.

In addition to proteins, viruses also contain genetic material, that could be either RNA or DNA. No virus contains both RNA and DNA. A virus is a nucleoprotein and the genetic material is infectious. In general, viruses that infect plants have single stranded RNA and viruses that infect animals have either single or double stranded RNA or double stranded DNA. Bacterial viruses or bacteriophages (viruses that infect the bacteria) are usually double stranded DNA viruses. The protein coat called capsid made of small subunits called capsomeres, protects the nucleic acid. These capsomeres are arranged in helical or polyhedral geometric forms. Viruses cause diseases like mumps, small pox, herpes and influenza. AIDS in humans is also caused by a virus. In plants, the symptoms can be mosaic formation, leaf rolling and curling, yellowing and vein clearing, dwarfing and stunted growth.

The process to standardize the naming of living organisms is called nomenclature. Obviously, the nomenclature is only possible when the organism is described correctly and we know to what organism the name is attached to this is identification. The system of providing scientific name with two components is called Binomial Nomenclature. The scientific name ensures that each organism is identified by only one name all across the world. They also ensures that such a name has not been used for any other known organism. Scientific names for plants are provided in ICBN and for animals, in ICZN.

(1). Who proposed binomial nomenclature?
(A) Carolus Linnaeus  (B) Charles Darwin  (C) Francis crick  (D) Albert Einstein

(2)Which of the following is an example of binomial scientific name?
(A) Green algae  (B) Rana tigrina  (C) Snow leopard  (D) China rose

(3). In binomial nomenclature, the name of organism consists of
(A) kingdom   (B) genus   (C) species   (D) Both B and C

(4). ICBN stands for
(A) Internal botanical congress names
(B) International center of botanical names
(C) International code of botanical nomenclature

Various parts of the plant such as stems leaves, and even fruits are modified into underground parts to perform various functions such as stems, leaves, and even fruits.
The stems in ginger and banana are underground and swollen due to storage of food. They are called rhizome. Rhizome of ginger is a modification of stem because it bears nodes, internodes, terminal buds, scaly leaves and buds, which give rise to aerial shoots. It is not a root because root does not have nodes and internodes. Also, rhizome does not perform the function of roots i.e. anchorage and absorption, rather it serve as reservoir for storage of food. Similarly, corm is an underground stem in Colocasia (jimikand) The tips of the underground stem in potato become swollen due to accumulation of food and forms tuber.
