Bacteria usually reproduce asexually. In case of sexual reproduction, certain plasmids genetic material can be passed between bacteria. On the other hand, viruses mainly carry information-for example, DNA or RNA, packaged in a protein and/or membranous coat.Viruses harness the host cell's machinery to reproduce.acteria usually reproduce asexually.

The vegetative form of B. cereus grows in a range of 10 to 50Â°C, with a temperature optimum between 30 and 40Â°C. However, the individual cold-tolerating strains can also multiply at temperatures of 4 to 6Â°C; in these cases the generation times are, however, considerably longer.
Soil temperatures at which vegetable seed will grow include the minimum temperature required for seed growth, an optimum temperature and a realistic soil temperature. The realistic soil temperature is somewhere between optimum and minimum; it is the temperature at which you should plant to insure maximum success.For instance, the optimum soil temperature for seed germination of vegetable crops, such as cucumber, cantaloupe, okra, pumpkin, squash and watermelon, is 95Â°F.However, if planted late enough during the year for soil to reach this temperature, summer heat will decrease plant vigor and yield.he realistic soil temperature is somewhere between optimum and minimum; it is the temperature at which you should plant to insure maximum success.
