True or False: Eukaryotes are good environmental indicators, producers, and CAN be pathogenic
Explanation
Eukaryotes are organisms that have complex cells with a nucleus. They can be found in various
environments and play important roles as environmental indicators and producers. Additionally, some
eukaryotes can also be pathogenic, meaning they have the potential to cause diseases in other
organisms. Therefore, the statement that eukaryotes are good environmental indicators, producers, and
can be pathogenic is true.

True or false: Algae can either be single celled or multicellular, are found in fresh and salt water, and
CAN be pathogenic
Explanation
Algae can indeed be single-celled or multicellular, and they are commonly found in both fresh and salt
water. However, algae are not typically pathogenic, meaning they do not cause diseases in humans or
animals. Therefore, the statement that algae can be pathogenic is false.

Algae contains ____ to trap sunlight
Explanation
Algae contains chlorophyll, a pigment that is responsible for trapping sunlight during the process of
photosynthesis. Chlorophyll absorbs light energy from the sun and converts it into chemical energy,
which is used by algae to carry out various metabolic processes. This pigment gives algae its green color
and is essential for their survival and growth.
Rate this question:
5.
This pigment found in algae is noted as a red/yellow collor
Explanation
Carotene is a pigment found in algae that is known for its red/yellow color. It is a type of carotenoid,
which is responsible for the vibrant colors in plants, fruits, and vegetables. Carotene is an important
pigment in algae as it helps in photosynthesis by absorbing light energy and converting it into chemical
energy. The presence of carotene gives algae its characteristic red/yellow hue, making it easily
identifiable.

6.
This pigment found in algae is noted as a yellow color and is also found in diatoms.
Explanation
Xantophyll is a pigment found in algae and diatoms that is noted for its yellow color. It is responsible for
the yellow hues observed in these organisms. Xantophyll is a type of carotenoid pigment, which is a class
of pigments found in various plants and algae. It plays a vital role in photosynthesis, absorbing light
energy and transferring it to chlorophyll molecules. Additionally, xantophyll acts as an antioxidant,
protecting cells from damage caused by reactive oxygen species.
