Plants can metabolize carbon dioxide in the air to produce valuable oxygen, and can help control cabin humidity. [4] Growing plants in space may provide a psychological benefit to human spaceflight crews. [4] The first challenge in growing plants in space is how to get plants to grow without gravity. [5]
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.

One astronaut on the International Space Station requires approximately "1.8 kilograms of food and packaging per day". [1] For a long-term mission, such as a four-man crew, three year Martian mission, this number can grow to as much as 24,000 lb (11,000 kg).

Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo. This is a pertinent stage in the plant life cycle that is followed by dormancy and germination . [ 1 ]
In nature, some seeds require particular conditions to germinate, such as the heat of a fire (e.g., many Australian native plants), or soaking in a body of water for a long period of time. Others need to be passed through an animal's digestive tract to weaken the seed coat enough to allow the seedling to emerge. [2] Malted (germinated) barley ...
