Coccolithophore are single-celled plankton with calcium carbonate shells. Live in tropical and sub-tropical zones.
True
A diatom is single-celled plankton with calcium carbonate shells. Live in tropical and sub-tropical zones.
False
A diatom is a unicellular photosynthetic alga with a unique glassy cell wall containing silica.
True
Foraminifera is a unicellular photosynthetic alga with a unique glassy cell wall containing silica.
False
Foraminifera is one of a group of tiny single-celled organisms that live in surface waters and whose secretions and calcite shells account for most of the ocean's carbonate sediments.
True
Coccolithophore is one of a group of tiny single-celled organisms that live in surface waters and whose secretions and calcite shells account for most of the ocean's carbonate sediments.
False
Calcium Carbonate is CaCO3 and found in macro and micro organisms, limestone or chalk, Tums, and marble.
True
Calcium Carbonate is CaCO2 and found in lithogenous sediments and Aspirin.
False
Calcium carbonate macro organism examples are snails, crustaceans, coral, and echinoderms.
