The study of plant response in space environments is another subject of astrobotany research. In space, plants encounter unique environmental stressors not found on Earth including microgravity, ionizing radiation, and oxidative stress. [23] Experiments have shown that these stressors cause genetic alterations in plant metabolism pathways.
Although starlings are a tropical family by origin, Tristram's starling is well adapted to living in a desert environment: it loses relatively little water to evaporation and produces less heat than expected for its base metabolic rate. Its dark plumage may help it survive in the desert winter, when temperatures are low but the Sun's radiation ...
Plants can metabolize carbon dioxide in the air to produce valuable oxygen, and can help control cabin humidity. [3] Growing plants in space may provide a psychological benefit to human spaceflight crews. [3] Usually the plants were part of studies or technical development to further develop space gardens or conduct science experiments. [1]
Monoptilon bellioides is a short annual plant; in seasons with very little rainfall, the plant may only grow to 1–2 centimetres (1 ⁄ 2 – 3 ⁄ 4 in), if it ...
The starlings are generally a highly social family. Most species associate in flocks of varying sizes throughout the year. Murmuration is the flocking of starlings, including the swarm behaviour of their large flight formations. [8] These flocks may include other species of starlings and sometimes species from other families.
Tillandsia is a genus of around 650 species of evergreen, perennial flowering plants in the family Bromeliaceae, native to the forests, mountains and deserts of the Neotropics, from northern Mexico and the southeastern United States to Mesoamerica and the Caribbean to central Argentina.
The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
Air spaces were needed between the cells to allow carbon dioxide to diffuse inwards. The center of the stem, the cortex, developed "chlorenchyma" – a plant tissue made up of relatively unspecialized cells containing chloroplasts, arranged into a "spongy layer" and a "palisade layer" where most of the photosynthesis occurs.
