Algae word list, defined
- ALGAE /ˈæl.dʒiː/ · noun
- Algae are simple, typically aquatic organisms that photosynthesize but lack the true roots, stems, leaves, and vascular tissues of plants, ranging from single-celled phytoplankton to large seaweeds. Related: seaweed, phytoplankton, kelp.
- PHOTOSYNTHESIS /ˌfoʊtoʊˈsɪnθəsɪs/ · noun
- The biological process by which plants, algae, and some bacteria use light energy to convert carbon dioxide and water into glucose and other organic compounds, releasing oxygen as a by-product.
- CHLOROPHYLL /ˈklɒrəfɪl/ (British); /ˈklɔːrəfɪl/ (US) · noun
- The green pigment found in plants, algae, and cyanobacteria that absorbs light energy and enables photosynthesis, converting carbon dioxide and water into sugars while releasing oxygen. Related: green pigment, photosynthetic pigment.
- PIGMENT /ˈpɪɡmənt/ · noun
- A substance that gives a material or living organism its color. The term also refers to such coloring matter collectively, as in skin pigment. Related: coloring matter, dye, tint, colorant.
- EUKARYOTE /juːˈkæri.oʊt/ · noun
- An organism whose cells contain a distinct membrane-bound nucleus and other membrane-bound organelles. Eukaryotes include animals, plants, fungi, and protists.
- PROKARYOTE /ˌproʊkæriˈoʊt/ · noun
- A single-celled organism whose cells lack a membrane-bound nucleus and the other membrane-bound organelles characteristic of eukaryotes. Prokaryotes include bacteria and archaea. Related: prokaryotic organism, prokaryotic cell, moneran.
- DIATOM /ˈdaɪ.ə.tɒm/ (UK); /ˈdaɪ.ə.tɑːm/ (US) · noun
- A microscopic single-celled alga of the class Bacillariophyceae, having a cell wall of silica consisting of two overlapping halves, found in freshwater and marine environments and forming a major part of plankton. Related: alga, microalga, plankton.
- DINOFLAGELLATE /ˌdaɪnoʊflædʒəleɪt/ · noun
- A dinoflagellate is a single-celled aquatic organism, typically marine, belonging to the phylum Dinoflagellata, characterized by the presence of two flagella used for locomotion. Many species are photosynthetic and form a major component of plankton, while some are responsible for bioluminescence or harmful algal blooms such as red tides. Related: flagellate, alga, plankton, microorganism.
- EUGLENA /juːˈɡliːnə/ · noun
- A euglena is a single-celled freshwater microorganism of the genus Euglena, characterized by an elongated body, a whiplike flagellum used for movement, and chloroplasts that allow it to produce its own food through photosynthesis. Related: flagellate, protist, microorganism.
- SPIROGYRA /ˌspaɪrəˈdʒaɪrə/ · noun
- A filamentous freshwater green alga of the genus Spirogyra, characterized by cells containing spiral or helical chloroplasts. The name is also used collectively for algae belonging to this genus.
- KELP /kɛlp/ · noun
- A large brown alga, or seaweed, that grows in the ocean, often forming dense underwater forests. Kelp is also used as a fertilizer, food source, and industrial material because it contains useful compounds such as iodine and alginates. Related: seaweed, alga, wrack.
- SEAWEED /ˈsiːwiːd/ · noun
- Any of various marine macroalgae, especially brown, red, or green algae growing along coasts and in shallow ocean waters. The term can also refer to harvested seaweed used as food, fertilizer, or an industrial material. Related: algae, macroalgae, sea algae, kelp.
