  • Diatoms: single-celled protist (algae) part of phytoplankton
  • Plankton: communityof organisms that float and drift
  • Organelles: tiny structures in cells that carry out important functions
  • Asexual Reproduction: the production of offspring by one parent
  • Sexual Reproduction: the production of offspring by two parents
  • Algal Bloom: algal bloom sudden increase in the algae population
  • Brown Tide:   an algal bloom of diatoms that clouds shallow, coastal waters

4.3 SECTION REVIEW

 

  1. glassy cell wall and position of the chloroplasts are adaptations that increase the rate of photosynthesis
  2. the marine animals depend on the diatoms as their food source
  3. it changes the water they swim or drink from brown

FACTS:

  1. shellfish such as mussels, clams ,oysters and many others consume diatoms by filtering them from the seawater.
  2. diatom are neede in sexual reproduction to develop either a male or female.
  3. there are more then 25,000 species of diatoms

Summary:

Diatoms are a big part of the ocean life they are needed by many species in the sea.They play a big part in sexual reproduction and asexual reproduction. Diatoms is the reason why most species are alive today and are healthy. Without diatoms many species wouldnt have a vey long life span today.

this is a test

a test I say
