Answer: Hemoglobin
Explanation: Hemoglobin is a protein very rich in iron found in red blood cells and is responsible for the transportation of Oxygen from the lungs to the whole body. Oxygen binds to the hemoglobin in red blood cells and the red pigmentation of blood that is highly oxygenated is due to the hemoglobin content found in RBC's.
Strigolactone underproducer is most likely to produce a bushier phenotype.
Therefore the correct answer is Option D.
<h3>What is the role of strigolactones in plant growth?</h3>
- Strigolactones are plant hormones which have a role in signaling.
- They control plant development and are released as root exudates to promote symbiotic relationship between plants and microbes in the soil.
- Strigolactones act as signaling molecules from roots to shoots to suppress the growth of secondary branches.
- Plant mutants that are not able to produce strigolactones (Strigolactone underproducer) produced many secondary branches resulting in a bushier phenotype.
- To prevent lateral branching and formation of bushier phenotype provide synthetic strigolactones (GR24) to the plant.
- Strigolactones also have a role in secondary thickening of the stem and promote the formation of lateral roots.
