Spores help some microorganisms survive in adverse conditions. True. The spore is the control unit of a cell. False. All bacteria require the same conditions to live and grow. False. The virus that causes hepatitis B is transmitted by: blood. Viruses are larger than bacteria.
spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. Spores thus differ from gametes, which are reproductive cells that must fuse in pairs in order to give rise to a new individual. Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction.

Aug 20, 2022 · Cells called spores — defined as cells with both dispersal capabilities (i.e., mobile cells) and reproductive capabilities (i.e., cells that can grow into new fungal organisms) are often important in both asexual and sexual reproduction.
Dec 16, 2015 · Tancredo Souza. 1496 Accesses. 2 Citations. Abstract. I discuss in this chapter all spore characteristics, structures and functions. AMF spores are composed by several walls, and each wall has its own function and characteristics to help AMF to survive.

Spore: Small reproductive body that detaches from the parent organism to produce new offspring without having to fuse with another reproductive cell. Mostly microscopic, spores can consist of one or several cells (but do not contain an embryo) and are produced in large numbers.

terial cell becomes inactive and develops a multi-lay-ered protective coating. Once the spore forms, a process called sporulation, the bacteria can potential-ly remain dormant for a very long time – germinating after years to centuries. The possibility of a dormant spore reviving after tens of thousands or millions of years remains speculative.
Jul 29, 2021 · Conidia — the asexual, non-motile spores of moulds — can live in a quiescent state that has been associated with major cytoplasmic changes such as modifications of osmolytes and lipid levels, a...
