Answer:
Letter A
Explanation:
From the description you make, it's likely that the structure with letter A is the chloroplast. It is round and small and it's free because of the pigment needed for photosynthesis (chlorophyll). It is located inside the cell, suspended in the cytoplasm.
A system that carries cytokinins from the roots to the rest of the plant is called xylem.

Xylem is a 'transport' tissue that moves water and minerals from roots to leaves. It consists of columns of hollow and dead cells. The xylem transport relies on a pulling force—tension.</span>

The amino acid sequence for the following DNA sequence is Met-Ser-Cys-His.
<h3>What is transcription and translation?</h3>
Transcription is the process of conversion of genetic information carried by the DNA into messenger RNA (mRNA).
- Sense strand of DNA is the one which runs in 5’ to 3’ direction and carries the information while antisense strand runs in 3’ to 5’ direction and serves as a template.
- E.g.: Antisense strand 3′−TACAGAACGGTA−5′
mRNA sequence 5’−ATGTCTTGCCAT−3’
Translation is the process of conversion of information carried by the mRNA into an amino acid sequence.
- The genetic code is read as a sequence of 3 nucleotides together at a time and is called codon.
- For example: 'ATG' is a start codon coding for methionine.
Here, mRNA sequence 5’−ATGTCTTGCCAT−3’
Amino acid sequence: Met-Ser-Cys-His
