Characteristics of phytoplankton
Some of the main characteristics of phytoplankton are the following:
- When too many nutrients are available, it can grow out of control and form harmful algal blooms.
- When uncontrolled growing flowers deplete their nutrients, the phytoplankton dies, sinks and decomposes.
- It has a great diversity in its species.
- It can be found in all Earth’s seas and oceans.
- Some types of phytoplankton are bacteria, protists, but most of them are unicellular plants.
- Like terrestrial plants, they have chlorophyll to capture sunlight and use photosynthesis to convert it into chemical energy.
- It consumes carbon dioxide and releases oxygen.
- Factors influencing phytoplankton growth include water temperature and salinity, depth, wind and the type of predators that come into contact with them.
Species of phytoplankton
There are thousands of phytoplankton species that inhabit the Earth’s different oceans. Each of them has the ability to adapt to the particular conditions of water in which they live. Aspects such as water clarity changes, nutrient content and salinity, can change the species that live in a particular place. There is a great diversity of species due to these reasons, and among the most common species that we can find we can mention:
- Diatoms
- Dinoflagellates
- Cyanophytes or blue-green algae
- Brown algae
- Cocolithophoridae
What do phytoplankton eat?
As for phytoplankton nutrition, it is important to mention that they are plants capable of carrying out photosynthesis process, which allows them to convert sunlight into energy by combining it with water and carbon dioxide to produce carbohydrates that are used as a nutrient. In addition to these aspects, it needs other nutrients that water provides such as nitrogen, phosphorus and iron. The first two components are necessary for its survival and reproduction. The food sources for phytoplankton are formed in nature from rock wear and the atmospheric conditions that can turn nitrogen into a productive substance for plants.
Bioluminescent of phytoplankton
The term bioluminescence refers to light production by some types of living organisms through a series of biochemical reactions involving an enzyme known as luciferase. Scientists have recently discovered that this type of plankton has the ability to shine when they move due to stress it causes them. They use bioluminescence as a defense mechanism to attract predators to the creature that tries to eat the plankton, causing predators to become confused. For it to become bioluminescent, it needs the presence of four elements: luciferin, luciferase catalyst, adenosine triphosphate and oxygen. The places where this phenomenon is most frequently seen are the Lakshadweep Islands, located in India, and VAadhoo Island in the Maldives.
Human consumption
It has a high nutritional content and health benefits and is full of nutritive particles that the human body can easily absorb. It is compared to other nutritional algae such as spirulina and chlorella, but phytoplankton could be even more potent and surprising. Adding a marine phytoplankton supplement to your diet can help improve mood, so it helps against depression.
One such study, conducted by Professor Yuzuru Shimizu at the University of Rhode Island, evaluated some marine organisms with anti-tumor properties. The highlight of the research was a unicellular plankton called dinoflagellates, which has been shown to have the potential to kill cancer, and in addition, marine phytoplankton can have the same effects of oxygenation and detoxification in the body as in the ocean.
Importance
It is the basis of marine food web, and they are the food base of primary producers. Plankton is an important food source for larger marine animals. Phytoplankton is the first link in the food chain, which is why they are known as primary producers, because they produce the first food forms. Estuary fish and shellfish depend on phytoplankton for survival.
