Q

Describe and identify: Diatoms

A

(Cut thru) most productive autotroph.Silicate shells. Contains accessory pigments to absorb more colors (including green)

  • Single cell reproduce by division
  • they eventually sink forming siliceous oozes

Q

Describe and identify: Dinoflagellates

A

(Whirling whip)- single cell autotrophs. Contain whip-like flagella. Many are bioluminescent( converting chemical energy into light)
-responsible for harmful red tides
