Difference between
Phototropism
and ramet
and photoperiodism
Answers
Answer:
Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. ...
Photoperiodism allows some plant species to flower—switch to reproductive mode—only at certain times of the year.
Phototropism
It is the growth of an organism in response to a light stimulus. It is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs.
Ramet
A clonal colony or genet is a group of genetically identical individuals, such as plants, fungi, or bacteria, that have grown in a given location, all originating vegetatively, not sexually, from a single ancestor. In plants, an individual in such a population is referred to as a ramet.
Photoperiodism
It is the physiological reaction of organisms to the length of night or a dark period. It occurs in plants and animals. It can also be defined as the developmental responses of plants to the relative lengths of light and dark periods.
