[B] Phloem Cells Phloem fibers are thick-walled, long spindle-shaped dead cells with a narrow lumen. They provide mechanical support to the tissue. Phloem parenchyma is the thin-walled living cells of the parenchyma. They have two functions, as (i) storage and (ii) lateral food conduction.

[B] Companion cells Tracheids and vessels are the xylem elements and are related to the transport of water. They are long tube-like structures with partially or completely breached walls to form water pipes (in vehicles) and pits in the cell wall (in tracheids) to conduct water.

[B] Companion cells
Tracheids and vessels are the xylem elements and are related to the transport of water. They are long tube-like structures with partially or completely breached walls to form water pipes (in vehicles) and pits in the cell wall (in tracheids) to conduct water. Sieve tubes are thin tube-like structures whose end walls are perforated with many holes and are called sieve plates. They are phloem elements and are the main food carrier elements. Associate cells contain many mitochondria and ribosomes and are the supporting units of sieve tubes.
In the complete absence of expression of lac operon, permease will not be synthesised which is essential for transport of lactose from medium into the cells. And if lactose cannot be transported into the cell, then it cannot act as inducers hence, cannot relieve the lac operon from its repressed staRead more

Some amino acids are coded by more than one codon (known as degeneracy of codons), hence on deducing a nucleotide sequence from an amino acid sequence, multiple nucleotide sequence will be obtained.

Genetic material of retrovirus is RNA. At the time of synthesis of protein, RNA is ‘reverse transcribed’ to its complementary DNA first, which is opposite to the central dogma. Hence, retrovirus are not known to follow central dogma.
