Onion is an underground crop and it have no involvement in the photosynthesis. So it have no chloroplast in their cell.
Hope this helps!

How can we solve it if we don't have the picture?
Answer:
The optimum pH of ATP synthase is 6.4 therefore maximum activity will occur at pH7 by the vesicle, however because the concentration of the three , is relatively the same , and exhibited equal effects on the pH, catalysis by the vesicle will not take place BECAUSE NO HYDROGEN ION IS AVAILABLE to supply the energy
Generally the synthase activity decreases with drops in pH. The lower pH of 6.5 from the set point value , will affect catalysis.
The low pH lead to increase in concentration of base in the buffer solution. Therefore more H + are produced .for the synthesis of ATP. The vesicle catalyzed ATP production. But the increase in hydrogen ion concentration with time affect the 3 dimensional structure of the ATPase synthase enzyme in the vesicle and increases the inhibitory effect of ADP therefore the vesicle stops the catalysis.
Answer:
c) The largest problem is that single viruses may create multiple plaques, resulting in overestimates of the number of viruses present.
Explanation:
- Plaque-based assays are the accepted method used for finding virus concentration in terms of infectious dose.
- Viral plaque assays determine the number of plaque forming units (pfu) in a virus sample, which is one measure of virus quantity.
Answer:
The correct answer will be option-A
Explanation:
The phylum which is characterised by the aseptate hyphae or hypha without septate belongs to Zygomycete.
The members of Zygomycetes are categorized into 10 orders and 122 genera.The fungi mostly grow near the cow dung and lack the fruiting bodies. They reproduce both ways that are sexual and asexual by producing spores.
Thus, option-A is the correct answer.
