Answer:
physical process
Explanation:
Assuming that there are no latency mechanisms that prevent germination, several factors are required for the embryo contained in the seed to restart its development.
Water Absorption
Embibition: It is a special case of a <u>physical phenomenon</u> called diffusion, and as such, there is a diffusion gradient. It is characterized by an increase in volume of the substance or body that embeds and is closely related to the properties of colloidal materials. The colloidal particles in the seed form a moderately rigid miscelar network, in which electric charges of opposite signs are oriented in a defined manner. When water penetrates the seed, one fraction occupies the free spaces and another chemically joins the substances of which the seeds are composed. The volume of the seeds increases with the embibition, but the final volume of the system (seed + water) is smaller than the sum of the initial individual volumes of seeds and water; This contraction of the system is proof of the occupation of the free spaces within the seed and the absorption of water in the colloidal matrix.
The embibition rate is affected by several factors that can determine the germination response of the seeds.

Mixtures are combinations of several substances. Each of the substances retains its physical properties. There are no new substances created. This is in contrast to a chemical reaction in which two or more reactants make new products.
There are two types of mixtures. The first kind of mixture is a homogenous mixture. Homogenous mixtures are uniform in the ratio of the combination of substances. throughout. All solutions are homogenous mixtures. Colloids (such as mile) and suspensions are also homogenous mixtures, but their particle sizes are larger than the particles that make up a solution. This larger particle size makes colloids and suspensions appear murky or opaque.
The second kind of mixture is a heterogeneous mixture. Heterogeneous mixtures are not uniform throughout. A classic example of a heterogeneous mixture is a trail mix- every handful you grab will be slightly different. If a suspension is allowed to sit, then its large particles will settle to the bottom of its container. At this point, the suspension would be classified as a heterogenous mixture.
