Polyarch and tetrarch vascular bundles generally occur in theses
1 Monocot stem and dicot root.
2 Dicot stem and monocot stem.
3 Dicot root and monocot root
4 Monocot root and dicot root
Explanation:
Exp:D Polyarch vascular bundles are found in monocot roots. The words polyarch' means "many arches" referring to the many xylem strands in each varcular bundle. This is because monocot roots do not have secondary growth. So, they do not need as many xylem strands to transport water and nutrients. - Tetrarch vascular bundles are found in dicot roots. These are four xylem strands in each vascular bundle.

Identify the monocot root characters I. Polyarch condition II. Large pith III. Presence of bundle sheath IV. Scattered vascular bundles
1 I and III only
2 I and II only
3 II and III only
4 IV only
Explanation:
Exp:B \(\bullet\) Monocot roots have the polyarch condition meaning that they have more than 6 xylem bundles. - Monocot roots have a central pith made up of parenchyma cells. In monocot roots, the pith is large and spongy. Which helps to store food and water. So, the I and II are character of monocot root.

What is the role of RNA polymerase III in the process of transcription in Eukaryotes?
1 Transcription of only snRNAs
2 Transcription of rRNAs \((28 \mathrm{~S}, 18 \mathrm{~S}\) and \(5.8 \mathrm{~S}\)
3 Transcription of tRNA, 5 srRNA and snRNA
4 Transcription of precursor of mRNA
Explanation:
Exp:C In eukaryote cells, RNA polymerase III is a protein that transcribes DNA to synthesize ribosomal \(5 \mathrm{~s}\) rRNA, tRNA and other small RNAs. - The DNA polymerases are involved mostly in DNA repair and translation DNA synthesis. - The main function of the third polymerase III is the duplication of the chromosomal DNA.

Which one of the following plants does not show plasticity?
1 Maize
2 Cotton
3 Coriander
4 Buttercup
Explanation:
Exp:A The ability of an organism to change its phenotype in response to different environment called plasticity. - Maize is monocot plant (Poaceae) in which hypodermis is sclerenchymatous so maize (zea mays) does not show plasticity.
