Propagation mode of algae (1) vegetative propagation
Asexual reproduction is a method of plant reproduction, which uses vegetative organs such as roots, leaves and stems to reproduce offspring. Asexual propagation can maintain the excellent characteristics of some cultivated plants and reproduce faster. It mainly includes rooting, layering, leaf cutting, bud cutting, cutting and grafting.
(2) Sexual reproduction
This method is widely used in general propagation, not only a large number of seeds produce new seedlings that can reproduce more, but also all famous species and flowers today are mostly improved and propagated through sexual reproduction.
(3) asexual reproduction
Asexual reproduction, also known as gametophyte reproduction, is a way of reproduction in which both parents produce offspring individuals without sexual cells. The characteristic of asexual reproduction is that only one parent participates in the generation of offspring. There are many forms of asexual reproduction, such as fission reproduction, budding reproduction, spore reproduction, vegetative reproduction and so on.
The living environment of algae plants can live in any environment.
Algae are widely distributed, have relaxed requirements on environmental conditions and strong adaptability, and can survive at extremely low nutrient concentration, extremely weak light intensity and quite low temperature. It can grow not only in rivers, streams, lakes and oceans, but also in short-term stagnant water or wet places.
From the tropics to the poles, from snow-capped mountains to hot springs, from wet ground to not very deep soil, algae are almost everywhere. All algae except Charophyta have marine species.
According to the ecological characteristics, algae plants are generally divided into phytoplankton, phytoplankton and benthic algae. Some algae, such as diatoms, dinoflagellates and unicellular species of Chlorophyta, and some filamentous species of Cyanophyta, float in oceans, rivers and lakes, which are called phytoplankton. Some algae, such as horsetail algae, float in the sargasso sea and are called floating algae.
