The seed is a representation of the basic unit of reproduction in flowering plants, it has the ability to transform to another plant and it also enables the survival of the species under unfavorable environmental conditions. The seeds acts as the storage of nutrients. The stored nutrients help the plants, grow survive and to reproduceCITATION Joh173 l 1033 (Harrison, 2017). It is beneficial for the seed to store nutrients for the plant embryo even after the plant is already acquiring its food through photosynthesis. The stored nutrients nourish the plant during winter when the sunlight available is limited and hence photosynthesis may not actively take place. The nutrients stored include carbohydrates, lipids and proteins. The nutrients as important in the formation of plant hormones such auxins which aid in the elongation of the plant. The stored nutrients may also nourish other tissues and cause them to be specialized for their functions.
Auxins are useful growth hormones produced naturally by plants. The production of auxins is aided by the availability of nutrients. Auxins are located in the shoots and root tips and facilitate: cell division, stem and root growth. Auxins affect the orientation of the plant by promoting cell division to one side of the plant in response to sunlight and gravity CITATION Mic13 l 1033 (Michael sauer, Stephanie Robert, 2013). Auxins stimulate the growth of the root geotropically and also promote the growth of the shoot by positively influencing the gibberlins which promote the elongation of the shoot. In this case the plant will curve downwards as the auxins will migrate away from the light and it will result in the growth of the shoot. Light is the energy source in plant growth.References.
