Answer 1

1) Generally speaking, bean plants have fewer than 100 nodules, soybean plants have several hundred, and peanut plants can have 1,000 nodules or more. Cut-open nodules from a legume displaying the reddish-pink colour of an active, healthy nodule.

2) Both of them have roots that extend far into the cup in an effort to find food to survive. Both of them have nodules.

3) The radish just occupies the cup's centre; the beans basically fill the entire space. not as many nodules as a bean plant.

what are nodules ?

On the roots of plants, particularly legumes, that collaborate with bacteria that fix nitrogen, root nodules can be seen. Capable plants develop a symbiotic association with rhizobia, a host-specific strain of bacteria, when nitrogen is scarce.
