Botany Quiz
You'll need to correctly answer at least 46 of the 51 questions below (at least 90%) to progress to the next lesson.
Question #1: Protists are unicellular in nature but can also be found as a colony of cells. Most protists live in water, damp terrestrial environments, or even as parasites. ... These organisms are usually unicellular, and the cells of these organisms contain a nucleus bound to the organelles.
Question #2: Chrysophyta is a phylum of multicellular marine or freshwater protists.
Question #3: These are all examples of Chrysophyta, which includes the chrysophytes or the Chrysophyceae (golden algae), xanthophytes or Xanthophyceae (yellow-green algae), and bacillariophytes or Bacillariophyceae (diatoms).
Question #4: Pyrrophyta or fire algae (Dino Flagellata) is a uniselular algae (single-celled) has a yellow brown color, but has two different flagellas, ribbon-shaped. It contains several pigments (chlorophyll A, C2, and pyridinine, but others have chlorophyll A, C1, C2 and fucosantin) that can photosynthesize.
Question #5: Rhizopoda is a broad group of protozoan amoeboid organisms placed in the kingdom Protista. They include the naked and testate amoebae, some members of the slime molds, and foraminifera. The latter are almost exclusively marine organisms, either benthic or planktonic.
Question #6: The Apicomplexa (also called Apicomplexia) is a tiny phylum of parasitic alveolates. None of them possess a unique form of organelle that comprises a type of plastid called an apicoplast, and an apical complex structure. The organelle is an adaptation that the apicomplexan applies in penetration of a host cell.
Question #7: Euglena, Phacus, Eutreptia, Trachelomonas, Peranema. (1) Euglena is a connecting link between animals and plants. (2) Euglena resembles the ancestral form which the plants and animals evolved. (3) Euglena is a free swimming fresh water flagellate. these are all
Question #8: A phylum or subphylum of protozoans that possess cilia during some phase of the life cycle and usually have nuclei of two kinds — compare sarcomastigophora.
Question #9: The primary feature of all protists is that they are eukaryotic organisms. This means that they have a membrane-enclosed nucleus.
Question #10: What is Algae?
Question #11: Chlorophyta is a taxonomic group (a phylum) comprised of green algae that live in marine habitats. Some of them are found in freshwater and on land. Some species have even become adapted to thriving in extreme environments, such as deserts, arctic regions, and hypersaline habitats.
Question #12: The blue-green algae, comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat.
Question #13: The Rhodophyta (red algae) are a distinct eukaryotic lineage characterized by the accessory photosynthetic pigments phycoerythrin, phycocyanin, and allophycocyanins arranged in phycobilisomes, and the absence of flagella and centrioles
Question #14: There are two large groups: the cellular slime molds (dictyostelids), such as Dictyostelium, and the acellular slime molds (myxomycetes), such as Physarum.
Question #15: The phylum containing the cellular slime molds. These are protoctists that pass through a unicellular stage of amoebas that feed on bacteria. Subsequently, these amoebas aggregate to form a fruiting structure that produces spores.
Question #16: A fungus (plural: fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, which is separate from the other eukaryotic life kingdoms of plants and animals.
Question #17: Ascomycetes are 'spore shooters'. They are fungi which produce microscopic spores inside special, elongated cells or sacs, known as 'asci', which give the group its name. Asexual reproduction is the dominant form of propagation in the Ascomycota, and is responsible for the rapid spread of these fungi into new areas.
Question #18: Basidiomycota
Question #19: Is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.
Question #20: Kingdom Plantae
Question #21: a class of Bryophyta comprising the liverworts and being distinguished from Musci by the presence of a usually thalloid gametophyte that is not produced from a protonema, unicellular rhizoids and elaters, and antheridia and archegonia that are borne on the thallus and produce a short-lived and simple sporophyte
Question #22: Zygomycota, or zygote fungi, is a former division or phylum of the kingdom Fungi. The members are now part of two phyla the Mucoromycota and Zoopagomycota. Approximately 1060 species are known. They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material.
Question #23: Hornworts are a group of bryophytes constituting the division Anthocerotophyta. The common name refers to the elongated horn-like structure, which is the sporophyte. As in mosses and liverworts, the flattened, green plant body of a hornwort is the gametophyte plant.
Question #24: Seedless Vascular Plants- what are two examples?
Question #25: Gymnosperms these are three examples
Question #26: All angiosperm plants have the characteristic vascular bundle with the xylem and phloem tissues for conduction of water, minerals, and nutrients. The plant body is well differentiated with a well-developed root system, shoot system, and leaves.
Question #27: Cycads are seed plants with a very long fossil history that were formerly more abundant and more diverse than they are today. They typically have a stout and woody trunk with a crown of large, hard and stiff, evergreen leaves. They usually have pinnate leaves.
Question #28: Coniferophyta is a division of plants, grouped within the gymnosperms, that consists of some 70 species across the three relict genera: Gnetum, Welwitschia, and Ephedra.
Question #29: Angiosperms-The flowering plants, also known as Angiospermae, or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,000 known genera, and 300,000 known species. Like gymnosperms, angiosperms are seed-producing plants.
Question #30: Cells and Seeds- define
Question #31: Define: Roots and shoots
Question #32: Waters and minerals-explain the functions of waters and minerals in plants.
Question #33: Explain the whole function of photosynthesis.
Question #34: Tissue through which most of the water and dissolved minerals utilized by the plant are transported from roots up.
Question #35: An impermeable waxy substance present in the cell walls of cork tissues
Question #36: Main storage carbohydrates in plants, stored in chloroplasts
Question #37: Secondary xylem that is actively conducting. Outside of dark central core of a tree, inside of vascular cambium.
Question #38: Where cell division and initiation of tissues and organs occur- a group of cells that continues to divide.
Question #39: All tissues outside of vascular cambium (includes inner bark).
Question #40: Specialized parenchyma cell cells adjacent to a sieve tube in the phloem of a flowering plant, believed to regulate the flow of nutrients through the tube.
Question #41: "Veneer" waterproofing on the outside of a leaf or topside of a plant
Question #42: Botany is the study of plants
Question #43: Gymnosperm is an uncovered seed.
Question #44: Plummule are the last true leaves of the plant.
Question #45: Sepals cover the bud
Question #46: Self-pollination is the ability of a plant to pollinate itself.
Question #47: Stamen is the female part of the plant
Question #48: Cotyledon are the parts of the seed that hold the food
Question #49: Phloem are tubes that carry soil up to the plant
Question #50: Radicle is the embryo's root.
Question #51: Draw and label a root system and flower parts. Save and upload as one file. You can also upload as an image file.
