In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual cells or groups of cells grow longer. Not all plant cells grow to the same length. When cells on one side of a stem grow longer and faster than cells on the other side, the stem bends to the side of the slower growing cells as a result.

Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling.
That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards). This behavior can be easily demonstrated with any potted plant. When laid onto its side, the growing parts of the stem begin to display negative gravitropism, growing (biologists say, turning; see tropism ...
Many plants grow food storage structures such as tubers or bulbs which may each develop into a new plant. [69] Some non-flowering plants, such as many liverworts, mosses and some clubmosses, along with a few flowering plants, grow small clumps of cells called gemmae which can detach and grow. [70] [71]

A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
When exposed to varying sounds, there were statistically significant results that showed an attractive response (roots grow toward) to water or sounds mimicking water, and an avoidance response (roots grow away from source) (p-value<0.002). In summary, this research showed that pea plants do, in fact, respond to acoustic frequencies. [15]
This tropical plant can easily grow to be 3 to 5 feet tall, so you may need a fairly large container. "You'll want to grow it in a pot that's at least 12 inches in diameter," says Kim Roman, ...
