Concept explainers
To discuss:
The sedimentation of wastes harming the coral reefs.
Introduction:
Coral reefs are “biologically valuable” because coral reefs are homes of thousands of marine species; they provide protection to shorelines and inhabitants living near coastal regions. They also support human life through development of pharmaceuticals to treat life-threatening diseases.
To discuss:
The symbiotic relationship between the dinoflagellates and corals.

- Aside from cleanliness and access to clean water, propose scientific ways in controlling parasitic diseases. You can use protozoans or invertebrates in your example.arrow_forwardHow are diatoms and dinoflagellates used in monitoring water quality? Cite two (2) examples. What are zooxanthellae? Describe their role in symbiotic relationships.arrow_forwardDescribe the two most common symbiotic relationships algae are found in.arrow_forward
- Dinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night. During the day, they carry out photosynthesis similar to other autotrophs. At night, however, they bioluminesce every time they are disturbed. They are often seen in the wakes of ships at night. While the reason for this bioluminescence is not fully understood, many scientists concur that it is a form of self-defense. If small fish begin to feed upon the protists, the protists will begin to bioluminesce. These flashes of light in the dark water can alert larger fish and draw them towards the small fish, upon which they prey. By making the small fish vulnerable, the dinoflagellates are able to protect themselves. Based on the information above, a researcher decides to design an experiment in which she is testing how long it takes for dinoflagellates to recover after different amounts of disturbance. She maintains 10 containers of dinoflagellates with similar temperature, salinity and…arrow_forwardDinoflagellates are unicellular, marine protists.

This algae deposits calcium carbonate in its cell walls, making it hard. 1. What type of organisms do you think eat this type of algae? 2. What role do you think this type of algae has in coral reefs and rocky shores? 3. Why do you think most red algae is typically found deeper in the ocean?arrow_forward
- What would happen to a coral animal if all its resident zooxanthellae died, but the animal itself remained relatively healthy?arrow_forwardPlankton can be divided into three groups: phytoplankton, ultraplankton, and nekton. True Falsearrow_forwardYou have discovered a new species aquatic protist that is a primary producer. It cannot swim on its own. It appears to be resistant to physical damage from wave action due to the presence of a glass-like wall. Which of the following organisms would this organism be most like? A) diatom B) dinoflagellate C) apicomplexan D) red algaarrow_forward
- Lichens are a mutualistic relationship between a fungus and an alga or cyanobacterium, or both. The diagram below shows their symbiotic relationship. What is the role of fungi in lichens?arrow_forwardList two protists that are ciliates or flagellates List two protists that are amoeboid list two organisms that cause diseas and what diseases they cause create a pie chart or bar graph comparing the forms of motilityciliates, flagellates and amoebaarrow_forwardWould corals be able to live without zooxanthellae?arrow_forward
