  2. Plant development - Wikipedia

    en.wikipedia.org/wiki/Plant_development

    This image shows the development of a normal plant. It resembles the different growth processes for a leaf, a stem, etc. On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate.

  3. AP Biology - Wikipedia

    en.wikipedia.org/wiki/AP_Biology

    Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".

  4. Epigenetics of plant growth and development - Wikipedia

    en.wikipedia.org/wiki/Epigenetics_of_Plant...

    Flowering is a pivotal step in plant development. Numerous epigenetic factors contribute to the regulation of flowering genes, known as flowering loci (FL). In Arabidopsis , flowering locus t is responsible for the production of florigen , which induces Turck_2008 in the shoot apical meristem, a special set of growth tissues, to establish ...

  5. Acid-growth hypothesis - Wikipedia

    en.wikipedia.org/wiki/Acid-growth_hypothesis

    Within the 20-year timespan, many scientists have actively contributed to examining and reevaluating Hager's acid-growth hypothesis. Despite the accumulation of observations that evidently identify the final target of the auxin-induced action to be H +-ATPase, which excretes H + protons to the apoplast and take in K + ions through its rectifying K + channel in the following years, the ...

  6. Primary growth - Wikipedia

    en.wikipedia.org/wiki/Primary_growth

    When apical buds are trimmed by gardeners, the shape and density of a tree or shrub changes as new, uninhibited branches grow en masse. Topiary garden. Beckley Park garden . In stems, primary growth occurs in the apical bud (the one on the tips of stems) and not in axillary buds (primary buds at locations of side branching).

  7. ABC model of flower development - Wikipedia

    en.wikipedia.org/.../ABC_model_of_flower_development

    ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.

  8. Epigenesis (biology) - Wikipedia

    en.wikipedia.org/wiki/Epigenesis_(biology)

    In biology, epigenesis (or, in contrast to preformationism, neoformationism) is the process by which plants, animals and fungi develop from a seed, spore or egg through a sequence of steps in which cells differentiate and organs form. [1] Aristotle first published the theory of epigenesis in his book On the Generation of Animals.

  9. Somatic embryogenesis - Wikipedia

    en.wikipedia.org/wiki/Somatic_embryogenesis

    Somatic embryogenesis is an artificial process in which a plant or embryo is derived from a single somatic cell. [1] Somatic embryos are formed from plant cells that are not normally involved in the development of embryos, i.e. ordinary plant tissue. No endosperm or seed coat is formed around a somatic embryo.
