Answer:
c. the plant root growing down into the soil
Explanation:
The plant root going down deep into the soil is an example of positive gravitropism. Gravity pulls everything towards the center of earth i.e. downwards and roots follow the direction of gravity automatically by growing downward towards soil that is why it is known as positive gravitropism. In short we can say that root favors the direction of gravity.
Shoot on the other hand show negative geotropism/gravitropism i.e. it grows towards the opposite direction of gravity. Shoot grow towards upside direction i.e. away from the surface towards sky.
I think the correct answer would be C. It would be restricting water and/or nutrients, instead of supplying ample quantities of both that would not change the results of the experiment. This is because you are still supplying the same amount of nutrients and other things needed by the plant so the ratio of the growth of the plants will still be the same.
Answer:
<h2>Chalamydomonas.</h2>
Explanation:
Protists are those organisms that are unicellular and eukaryotic in nature. They are present in diverse forms and structures and show different types of characteristics/. There are many protists that are harmful to human beings and some other organism that causes certain diseases called parasitic protists such as protozoans, trichomonas and some other. There are some protists that are not parasitic in nature such as Chlamydomonas and some other. Protists have different types of the mode of nutrition that may be autotrophic, saprophytic and parasitic and some other.
