Seeds can be difficult to acquire, and some plants do not produce seed at all. Some plants (like certain [4] plants modified using genetic use restriction technology) may produce seed, but not a fertile seed. [5] In certain cases, this is done to prevent the accidental spreading of these plants, for example by birds and other animals. [6]

Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling.
The seeds are sown from December to January in small plots (almacigas) sheltered from the sun, and the young plants when at 40 to 60 cm (16 to 24 in) in height are placed in final planting holes (aspi), or if the ground is level, in furrows (uachos) in carefully weeded soil. The plants thrive best in hot, damp and humid locations, such as the ...
In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and the gametophyte is very small. Flowering plants reproduce sexually using flowers, which contain male and female parts: these may be within the same ( hermaphrodite ) flower, on different flowers on the same plant , or on different plants .
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.
Plants do not have nervous systems or any will for their actions. Even so, scientists are able to observe mechanisms that help their offspring thrive as they grow. All organisms have mechanisms to increase survival in offspring. [15] Offspring care is observed in the Mammillaria hernandezii, a small cactus found in Mexico. A cactus is a type of ...

In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule does not occur until the cotyledons have grown above ground. This is epigeal germination. However, in seeds such as the broad bean, a leaf structure is visible on the plumule in the seed. These seeds develop by ...
