[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.
Plants grown inflight experience a microgravity environment, and plants grown on the surface of Mars experience approximately 1/3 the gravity that Earth plants do. However, plants experience normal growth given that directional light is provided. [10] Normal growth is classified as opposite root and shoot growth direction.
A botanical garden is a place where plants, especially ferns, conifers and flowering plants, are grown and displayed for the purposes of research and education. This distinguishes them from parks and pleasure gardens where plants, usually with showy flowers, are grown for public amenity only.
