Plankton avoid sinking through increased surface area. Flattened bodies and appendages, spines, and other body projections slow sinking by adding surface area without increasing density. Some phytoplankton also avoid sinking by forming large chains.

What adaptations have phytoplankton made to stay at the sea surface?
Because phytoplankton are tiny, they don't weigh very much and they have a large surface area relative to their volume, which helps them float. Adaptations such as spines increase the surface area even more and prevent phytoplankton from sinking too fast.
How does plankton survive?
Phytoplankton make their energy through photosynthesis, the process of using chlorophyll and sunlight to create energy. Like other plants, phytoplankton take in carbon dioxide and release oxygen. ... Phytoplankton rely on nutrients found in their surroundings, such as phosphate, nitrate, and calcium, to thrive.
How does a plankton protect itself?
The plankton try to protect themselves by producing a chemical compound called DMSP, which some scientists believe helps strengthen the plankton's cell walls. This chemical gets broken down in the water by bacteria, and changes into another substance called DMS.
What are the characteristics of plankton?
Plankton are predominantly free-floating organisms that move with the ocean currents. Many different species make up plankton, so they are defined by this 'free-floating' characteristic rather than their biological classification.
What are some structural adaptations shared by all species of plankton?
All species of plankton (both phyto and zoo) have certain structural adaptations help to keep them afloat in the water column. These adaptations include: flat bodies, lateral spines, long thin appendages, which increase the amount of their body surface area in contact with the water.
What adaptations will your plankton have to stay buoyant and prevent predation?
Plankton avoid sinking through increased surface area. Flattened bodies and appendages, spines, and other body projections slow sinking by adding surface area without increasing density. Some phytoplankton also avoid sinking by forming large chains.
What happens if plankton dies?
If all the plankton disappeared it would increase the levels of carbon in our air, which would not only accelerate climate change, but also make it dificult for humans to breathe.
Why is plankton important to the ecosystem?
Plankton are an essential component of life on Earth. Marine plankton, found in all ocean ecosystems, play a critical role in maintaining the health and balance of the ocean and its complex food webs. ... These microscopic organisms also cycle most of the Earth's carbon dioxide between the ocean and atmosphere.
What does a plankton do?
Phytoplankton are microscopic plants, but they play a huge role in the marine food web. Like plants on land, phytoplankton perform photosynthesis to convert the sun's rays into energy to support them, and they take in carbon dioxide and produce oxygen.
Does plankton create clouds?
DMS can also serve the same purpose. Once in the atmosphere, DMS is quickly altered by sunlight into small, sticky molecules that water droplets glom onto. When large amounts of DMS from a phytoplankton bloom float from the ocean up into the atmosphere and hitch up with water vapor, a cloud can be born.
How can plankton avoid being seen by predators?
They flee even from the chemical scent of the predator but are most agitated when sensing a feeding predator,” said Menden-Deuer. When the scientists provided the phytoplankton with a refuge to avoid the predator – an area of low salinity water that the predators cannot tolerate – the phytoplankton moved to the refuge.
What is plankton in real life?
In real life, plankton are very different from the Spongebob Squarepants character. Plankton describes all sorts of floating large and mini organisms in the ocean, like animals and plants. ... That's why we call them “micro” organisms.
Can you see plankton with your eyes?
Some plankton are big enough to be seen with the naked eye. Try this the next time you visit a pond or lake: scoop up a glass of water and hold it up to the light. Unless the water is very dirty, you should be able to see small specks swimming around.
