Plankton Classfication
What is one way to classify different types of plankton?
Size, type, or how long they spend drifting
Where do plankton live?
In lakes, rivers, ponds, oceans, wetlands and other bodies of water across the globe. (i.e. most bodies of water)
Many of the organisms you encountered in the plankton tow are "invertebrates." What does that mean?
They don't have vertebrae (or bones)
Where did we go to perform the plankton collection?
Crystal pond
In the womb/inside the mother's body
True or false: All plankton are microscopic
False
True or false: Different planktonic organisms reproduce sexually or asexually
True
True or false: Some types of plankton have serotonergic neurons.
True
What is a pipette? How is it used?
Name three environmental factors that can affect development
Diet (alcohol, cigarettes), pollutants (oil, mercury, nitrates), predators, temperature, light etc
What was the most abundant type of crustacean in the plankton samples you collected?
Daphnia (water flea)
What was a behavior you observed in the animal plankton you collected?
Swimming
What feature allows some planktonic organisms to move around?
Cilia or flagella
If you want to make a 1:20 dilution in water, how much water would you need to add for a total of 20 uL?
19 uL
Which type of plankton is responsible for producing most of the breathable oxygen on Earth?
Diatoms
What are the two main types of plankton?
Zooplankton and phytoplankton
Where do some animal plankton digest their food?
In their gut or digestive tract
What makes some algae appear green
Chlorophyll
How does a light microscope work?
It uses lenses to bend light towards the eyes and makes the object appear larger than it is
Name three types of professions that use knowledge of developmental biology
Medicine, ecology, neurobiology, psychology, etc
What characteristics do scientists use to classify an organism as planktonic?
An organism is considered planktonic if it is carried by water movement and cannot swim against this movement.
How do some plankton get energy?
By using the sun's energy to make sugar (photosynthesis) OR by eating other organisms (heterotrophy) - only need one of these answers
Where is DNA found in the planktonic organisms?
In their cells
In a biology lab, what does it mean to "fix" an animal?
To "fix" is to euthanize an animal and preserve its current cell structure and physiology
