3why might a horticulturist not want a plant to reproduce sexually by seeds

Horticulture is the branch of plant agriculture which uses asexual or vegetative reproduction. This means that is based on the ability of plants to regenerate tissues and parts. As a result of asexual reproduction, the plants are the same, cloned (there is no genetic variation like in reproduction that uses seeds, sexual). Three reasons why might a horticulturist not want a plant to reproduce sexually by seeds:

1. In asexual reproduction superior plant may be reproduced endlessly without variation,

2. Asexual reproduction may be an easier technique,

3. Asexual reproduction is faster because there are no seed dormancy problems and the juvenile nonflowering stage is eliminated or reduced.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
