Question

compare table 3.4 with table 3.6. sugars are an immediate energy source in cells. in plant cells, glucose (a primary energy molecule) is often stored in the form of starch. is glucose stored as starch in the potato? __________ is glucose stored as starch in the onion? ________ does this explain your results in table 3.6? ________ why? __________

Explanation:

In plants, glucose is often stored as starch. Potatoes are known to store glucose as starch. Onions store glucose in the form of sugars other than starch mainly. This can be related to their different physiological functions and storage - mechanisms.

Answer:

Is glucose stored as starch in the potato? Yes
Is glucose stored as starch in the onion? No
Does this explain your results in Table 3.6? It may explain differences in sugar - starch content if shown in the table.
Why? Potatoes are storage organs for starch, while onions have different storage compounds for energy.
