In an experiment, Marlene removes the six anthers from the flower. What best describes the ability of the altered flower to form
Alik [6]

Ans.

In flowering plants, the male reproductive part or stamen is made up of a stack-like structure, known as filament and an ovule-like structure, known as anther. In anthers, microsporangia are present that produce pollen through mitosis.

Thus, 'if anthers are removed from a flower, it will not be able to form seeds as seeds are developed from zygote, that forms by the fusion of male gamete (pollen) and female gamete (ovum).'

Explanation:

As given;

Initial population of bacteria= 1000;

Log phase growth is exponential phase, period in which bacteria gets double.

Generation time= 15 minutes;

it means, bacteria get double in every 15 minute,

so after 2 hours, bacteria will have 8 generation times;

so the final generation of bacteria is =1000 X 2^8.

Final bacterial generation after two hours = 256,000(1000 X 2^8)
