Answer:
Dinoflagellates
Explanation:
Protists are unicellular eukaryotes and dinoflagellates is a protist that is responsible for causing annual Florida red tides. When a large amount of dinoflagellates accumulates in the ocean they make the sea color red which is also called an algal bloom.
They also secrete a toxin that kills lots of aquatic animals. They are also toxic to other creatures like birds, humans. They come together to reproduce in a definite area therefore they accumulate together in large amounts causing red tides annually. Therefore the correct answer is dinoflagellates.
Kingdom plantae is the only kingdom that contains all of those characteristics
All fungi are called heterotrophic eukaryotes. The correct answer will be B.
The answer is endoplasmic reticulum. There are two types of the organelle. The rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The RER has ribosomes attached to its outer membrane hence mainly folds, modifies and transports proteins. SER, on the other hand, is significant in the modification and transportation of lipids.
