  2. Plant reproduction - Wikipedia

    en.wikipedia.org/wiki/Plant_reproduction

    The life cycles of these plants start with haploid spores that grow into the dominant form, which is a multicellular haploid gametophyte, with thalloid or leaf-like structures that photosynthesize. The gametophyte is the most commonly known phase of the plant.

  3. Agricultural cycle - Wikipedia

    en.wikipedia.org/wiki/Agricultural_cycle

    The agricultural cycle is the annual cycle of activities related to the growth and harvest of a crop (plant). These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others. Without these activities, a crop cannot be grown.

  4. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    The Calvin cycle is present in all photosynthetic eukaryotes and also many photosynthetic bacteria. In plants, these reactions occur in the stroma, the fluid-filled region of a chloroplast outside the thylakoid membranes. These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them.

  5. Biological life cycle - Wikipedia

    en.wikipedia.org/wiki/Biological_life_cycle

    In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...

  6. Alternation of generations - Wikipedia

    en.wikipedia.org/wiki/Alternation_of_generations

    The life cycle of a dioecious flowering plant (angiosperm), the willow, has been outlined in some detail in an earlier section (A complex life cycle). The life cycle of a gymnosperm is similar. However, flowering plants have in addition a phenomenon called ' double fertilization '.

  7. The Private Life of Plants - Wikipedia

    en.wikipedia.org/wiki/The_Private_Life_of_Plants

    The Private Life of Plants is a BBC nature documentary series written and presented by David Attenborough, first shown in the United Kingdom from 11 January 1995. A study of the growth, movement, reproduction and survival of plants , it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth .

  8. C3 carbon fixation - Wikipedia

    en.wikipedia.org/wiki/C3_carbon_fixation

    Calvin–Benson cycle. C 3 carbon fixation is the most common of three metabolic pathways for carbon fixation in photosynthesis, the other two being C 4 and CAM.This process converts carbon dioxide and ribulose bisphosphate (RuBP, a 5-carbon sugar) into two molecules of 3-phosphoglycerate through the following reaction:

  9. Plant development - Wikipedia

    en.wikipedia.org/wiki/Plant_development

    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. Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [10]
