[#846] Mass flow hypothesis was put forward by
Correct Answer
(B) Munch
Explanation
Solution: Mass flow hypothesis was put forward by Munch. Theory to explain the movement of sap through the phloem. It was proposed by Ernst Munch, a German plant physiologist in 1930. A high concentration of organic substances, particularly sugar, inside cells of the phloem at a source, such as a leaf, creates a diffusion gradient that draws water into the cells from the adjacent xylem.
[#847] Smut includes in
Correct Answer
(B) Basidiomycotina
Explanation
Solution: Smut includes in Basidiomycotina. Basidiomycota is a group of fungi that includes mushrooms, bracket fungi, smuts, and rusts. These fungi are more prevalent in humid conditions. The smuts are multicellular fungi characterized by their large numbers of teliospores. The smuts get their name from a Germanic word for dirt because of their dark, thick-walled, and dust-like teliospores. The smuts are grouped with the other basidiomycetes because of their commonalities concerning sexual reproduction.
[#848] Fertilization is synonym with
Correct Answer
(B) Syngamy
Explanation
Solution: Fertilization is synonym with Syngamy. Fertilization also known as generative fertilization, syngamy, and impregnation is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development. Processes such as insemination or pollination which happen before the fusion of gametes are also sometimes informally called fertilization.
[#849] Which plant virus was observed 1 st under electron microscope?
Correct Answer
(C) TMV
Explanation
Solution: TMV plant virus was observed 1 st under electron microscope. Tobacco mosaic virus (TMV) is a positive-sense single-stranded RNA virus species in the genus. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves. TMV was the first virus to be discovered. It is the first pathogen identified as a virus. The virus was crystallized by W. M. Stanley. It has a similar size to the largest synthetic molecule, known as PG5.
[#850] Which is known as Dead man's finger?
Correct Answer
(A) Xylaria polymorpha
Explanation
Solution: Xylaria polymorpha is known as Dead man's finger. Xylaria polymorpha, commonly known as dead man's fingers, is a saprobic fungus. It is a common inhabitant of forest and woodland areas, usually growing from the bases of rotting or injured tree stumps and decaying wood. It has also been known to colonize substrates like woody legume pods, petioles and herbaceous stems.
