Question

Golden algae are a group of protists whose color is due to carotenoid pigments: yellow and brown. Most have two flagella

and all are photosynthetic. A group of students was given a significant sample of one of these (Dinobryon) that is colonial.
Their instructions for the project were to design two or more experiments that could be done with these organisms.

Since these organisms are protists, which of these characteristics could the students assume to be true?

A) All of them are marine.
B) Each has a single circular molecule of DNA.
C) The organisms are photosynthetic.
D) They lack membrane-bound organelles.
E) They are single-celled."

Answer 1

Golden algae are photosynthetic and single-celled organisms that can be found in both marine and freshwater environments.

Step-by-step explanation:

Based on the given information, the students can assume that the characteristic of being photosynthetic is true for the golden algae. Golden algae, along with brown algae and diatoms, are part of the stramenopiles group, which is known for its photosynthetic members. This means that these organisms can produce their own food using sunlight.

In addition to being photosynthetic, golden algae are also known to be single-celled. They are largely unicellular, although some species can form large colonies. So, the students can assume that the golden algae they are working with are made up of single cells.

However, the students cannot assume that all golden algae are marine. While they can be found in marine environments, they can also be found in freshwater environments. So, the habitat of golden algae can vary.
