Plankton

Front 1

What are the three major groups of plankton?

Back 1

-Phytoplankton: which are pohotoautotrophs, mostly unicellular, and are at the base of the food web.
-Zooplankton: which are both unicellular and multicellular.
-Bacterioplankton: which serve a diverse role in marine ecosystems.

Front 2

What are the 4 size groups of plankton?

Back 2

-Picoplankton: < 2 - 3micrometers
-Nanoplankton: 2 - 20micrometers
-Microplankton: 20 - 200micrometers
-Macroplankton: 200micrometer - 2mm

Front 3

What are the two groups of diatoms by shape?

Back 3

-Pennate
-Centric

Front 4

What is the difference in material used for the stucture of diatoms, dinoflagellates, and coccolithophorids?

Back 4

-For their body structure, diatoms use silica, coccolithophores use calcium carbonate, and dinoflagellates use cellulose.

Front 5

What is the genus of the most abundant cyanobacterium in the oceans?

Back 5

-Procholorococcus and Synechococcous
(blue-green algae)

Front 6

What are the two groups of zooplankton based on life cycle?

Back 6

-Holoplankton: spend their entire lives as plankton.
-Meroplankton: Includes eggs, larvae, and juveniles of many species that are only plankton for a portion of their lives.

Front 7

How big are bacterioplankton

Back 7

- 1-2 micrometers
-microbial loop: bacteria can take up dissolved organic material.

Front 8

How are plankton sampled?

Back 8

- Plankton can be sampled with nets with flow meters, and multiple net systems.
-Sonar can be used for zooplankton density.
-Plankton can be recorded (video)
-Optical instruments can be used to measure natural fluorescent signal from cells.
