List of Key Term definitions

  1. Fern key term.

    1. Fern

    A fern is a green flowerless plant that usually has divided leaves and grows in damp, shady places. Ferns are unique as they have two separate independent living stages.

  2. Botany key term.

    2. Botany

    Botany is the scientific study of plants. This field of study encompasses terrestrial, freshwater and ocean plants, as well as algae and some non-plants like fungi.

  3. Biosystematics key term.

    3. Biosystematics

    The study of the variation and evolution of a population of organisms in relation to their taxonomic classification.

  4. Classification key term.

    4. Classification

    The process of ordering living things into a system that allows scientists to identify them. The Linnaean classification system groups organisms based on what species they are most closely related to.

  5. Herbarium  key term.

    5. Herbarium

    A collection of dried plants mounted and classified for botanical study or the building or container that holds the plant collection.

  6. Rhizome key term.

    6. Rhizome

    A root-like subterranean stem that usually sends roots below and sends up shoots. In ferns rhizomes, can be erect, creeping or vertical (forming a trunk).

  7. Frond key term.

    7. Frond

    The leaf of a fern. Fronds range greatly in size and can be undivided or multidivided. Fronds serve the dual purpose of photosynthesis and reproduction.

  8. Sporangia key term.

    8. Sporangia

    The structures in which spores are produced. Sporangia are found on the underside of fern fronds.

  9. Hybrid key term.

    9. Hybrid

    The offspring of two different plant species.

  10. Long-distance dispersal key term.

    10. Long-distance dispersal

    The movement of a plant or animal across a long distance of unsuitable habitat. Lightweight fern spores scatter easily in the wind and, under ideal conditions, can travel vast distances.

  11. Molecular analysis key term.

    11. Molecular analysis

    The extraction and examination of DNA from cells to reveal information about the evolution and the relationships of different species.

  12. Adaptation key term.

    12. Adaptation

    An alteration or adjustment in structure that is often hereditary. An adaptation allows a species to improve its condition in relation to its environment.

  13. Propagation key term.

    13. Propagation

    To multiply by any process of natural reproduction. Ferns propagate through spore dispersal, by transplanting rhizomes and in some cases through bulbils.

Science Learning Hub Survey 2014

Dear Hub visitor,

You're invited to participate in an online survey about the New Zealand Science Learning Hub. This survey was designed to help Hub staff enhance and develop further the site. This is different from our November 2013 survey, so even if you took part in that survey, we would appreciate you taking this survey as well.
