  2. Plants in space - Wikipedia

    en.wikipedia.org/wiki/Plants_in_space

    Zinnia plant in bloom aboard an Earth orbiting space station. The growth of plants in outer space has elicited much scientific interest. [1] In the late 20th and early 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment, sometimes called space gardens. [1]

  3. Astrobotany - Wikipedia

    en.wikipedia.org/wiki/Astrobotany

    Tikhov's research into astrobotany would later develop into research into growing plants in space, or demonstrating the possibility of plants to grow in extraterrestrial conditions (especially comparing the climate of Mars and Siberia), but he was the first known astronomer to use color to attempt to measure the level of vegetation on an ...

  4. Space farming - Wikipedia

    en.wikipedia.org/wiki/Space_farming

    Essentially, the space farm turns the spaceship into an artificial ecosystem with a hydrological cycle and nutrient recycling. [4] [5] In addition to maintaining a shelf-life and reducing total mass, the ability to grow food in space would help reduce the vitamin gap in astronaut's diets and provide fresh food with improved taste and texture.

  5. Vegetable Production System - Wikipedia

    en.wikipedia.org/wiki/Vegetable_Production_System

    A Veggie module weighs less than 8 kg (18 lb) and uses 90 watts. [7] It consists of three parts: a lighting system, a bellows enclosure, and a reservoir. [8] The lighting system regulates the amount and intensity of light plants receive, the bellows enclosure keeps the environment inside the unit separate from its surroundings, and the reservoir connects to plant pillows where the seeds grow.

  6. Alternation of generations - Wikipedia

    en.wikipedia.org/wiki/Alternation_of_generations

    Alternation of generations (also known as metagenesis or heterogenesis) [1] is the predominant type of life cycle in plants and algae. In plants both phases are multicellular: the haploid sexual phase – the gametophyte – alternates with a diploid asexual phase – the sporophyte.

  7. Wolffia - Wikipedia

    en.wikipedia.org/wiki/Wolffia

    The growth rate of Wolffia varies within and among species. The rates of photosynthesis and respiration also vary proportionately to growth rate. The fastest growth rate (in fact, the fastest growth rate of any flowering plant) is shown by a clone of Wolffia microscopica, with a doubling time of 29.3 hours.

  8. Timeline of plant evolution - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_plant_evolution

    Sphenophyllum was a slender climbing plant with whorls of leaves, which was probably related both to the calamites and the modern horsetails. Cordaites, a tall plant (6 to over 30 meters) with strap-like leaves, was related to the cycads and conifers; the catkin-like inflorescence, which bore yew-like berries, is called Cardiocarpus. These ...

    A tropical plant community on Diego Garcia Rangeland monitoring using Parker 3-step Method, Okanagan Washington 2002. Plant ecology is a subdiscipline of ecology that studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among plants and between plants and other organisms.
