Question

the scientist konstantin mereschkowsky knew in the early 1900s that plants make their own food by using sunlight. he also saw tiny parts in plants called chloroplasts that do not appear in any animals. he hypothesized that chloroplasts are what help plants make food. after many more observations of all types of plants and animals, scientists are convinced today that chloroplasts make food for plants. has the study of chloroplasts been scientific or pseudoscientific? scientific, because a hypothesis and observations were made and then a conclusion was drawn scientific, because scientists made a hypothesis and conclusion before making any observations pseudoscience, because a hypothesis was believed to be true before any observations were made pseudoscience, because beliefs in chloroplasts are based on subjective opinions

Explanation:

In scientific study, a hypothesis is formed (chloroplasts help plants make food). Then, multiple observations (of various plants and animals) are conducted. Based on these observations, a conclusion is drawn (chloroplasts make food for plants). This follows the scientific method. Pseudoscience, on the other hand, might rely on unfounded beliefs or skip proper observation - hypothesis - conclusion steps.

Answer:

scientific, because a hypothesis and observations were made and then a conclusion was drawn
