Definitions 1
These are organisms that break down dead organic matter into smaller molecules.
What are decomposers?
These are tiny floating organisms that are either small animals or protozoa.
What are zooplankton?
What is they produce large amounts of oxygen and their fossilized shells can be mined for commercial products like toothpaste and filters?
What is kingdom Monera?
This a prokaryotic, single celled, microscopic organism.
What is bacteria?
This refers to a cell that contains half the normal number of chromosomes (one from each pair).
What is haploid?
Diatoms are members of this kingdom.
What is kingdom Protista?
Diatoms under these three types of reproduction.
What is two forms of asexual reproduction: (1)splitting the frustule in two and forming new diatoms 2) shedding the frustule and forming a new auxospore) and sexual reproduction where fertilization of gametes forms a new auxospore that grows a new frustule.
This refers to the complete body of a multicellular alga, not differentiated into true stems or roots.
This is a close relationship between 2 species where at least 1 benefits.
What is symbiosis?
The White Cliffs of Dover in England are thought to have once been underwater because they are composed of this.
What are the tests of foraminiferans?
Ciliates from the phylum Ciliophora are a type of this.
What is marine protozoans?
This is the function of the pneumatocysts on a thallus.
What is enable fronds to float on the water surface, maximizing exposure to sunlight and enhancing photosynthesis?
These are microscopic photosynthetic organisms that drift in the water.
This is a plant body typical to algae that is not differentiated into stem and leaves and lacks true roots and a vascular system.
What is a thallus?
Algin is an emulsifying agent that is produced from this type of algae.
What is brown algae?
Foramiferans and Radiolarians are members of this group of marine organisms.
What are zooplankton?
This is the most common lifecycle of marine algae.
What is alternation of generations?
This is a cell that has chromosomes that come in pairs.
What is diploid cell?
This is an organism that results from symbiosis between a fungus and an alga.
What is a lichen?
Cyanobacteria are not considered algae for this reason.
What is they are prokaryotic like bacteria?
Kelp is not a marine plant, but is this instead.
What is multicellular brown algae?
This part of the red mangrove can help to accumulate sediment buildup.
What are prop roots?
