Study Notes
Volvox
- Common name is Green Alga; scientifically classified as Volvox globator.
- Belongs to Kingdom Plantae, Phylum Chlorophyta, Class Chlorophyceae.
- Autotrophic; capable of producing food via photosynthesis.
- Asexually reproduces by cell division, forming daughter colonies; also reproduces sexually through oogamy and zygospore formation.
- Unique features include spherical shape with two flagella and a red eyespot for light detection.
- Found in freshwater bodies like lakes and pools.
Fucus
- Known as Rockweed or Brown Algae; classified as Fucus vesiculosus.
- Falls under Kingdom Chromista, Phylum Phaeophyta, Class Phaeophyceae.
- Autotrophic; produces its own food through photosynthesis.
- Lacks classical plant structures; acquires minerals directly from water through holdfasts, stripes, and blades.
- Reproduces sexually with multicellular organs for male (antheridia) and female (oogonia) gametes in conceptacles.
- Grows up to 35 inches in length and serves as a nutritional supplement.
Euglena
- Commonly referred to as Euglena, scientifically named Euglena gracilis.
- Part of Kingdom Excavata, Phylum Euglenida, Class Euglenoids.
- Mixotrophic; can consume food and perform photosynthesis.
- Utilizes phagocytosis to digest food within a food vacuole.
- Reproduces asexually via cell division, with waste removed through a contractile vacuole.
- Notable for its flexible pellicle and eyespot for sunlight detection; movement is facilitated by flagella.
Amoeba
- Common name is Amoeba; scientifically identified as Acanthamoeba polyphaga.
- Located in Kingdom Protista, Phylum Rhizopoda, Class Tubulinea.
- Heterotrophic; consumes food through phagocytosis and intracellular digestion in a vacuole.
- Exhibits an open circulatory system; waste removal via a contractile vacuole.
- Reproduces asexually through mitosis.
- Unique characteristics include shape-shifting via pseudopods and two types of cytoplasm: endoplasm (dark interior for food consumption) and ectoplasm (clear exterior for water absorption).
Paramecium
- Referred to as paramecium; scientifically classified as Paramecium caudatum.
- Part of Kingdom Protista, Phylum Ciliophora, Class Oligohymenophorea.
- Heterotrophic; requires food acquisition through ingestion.
- Features an open circulatory system; waste expelled through an anal pore.
- Reproduces both sexually through conjugation and asexually via binary fission.
- Notable for being the most complex single-celled organism, with two nuclei: a macronucleus (controls general functions) and a micronucleus (controls reproduction).
Vorticella
- Common name is Vorticella; scientifically identified as Vorticella campanula.
- Further information on classification, reproduction, and characteristics is necessary for a complete overview.
