What is the meaning of the word 'gemmule'?
- A gemmule is a reproductive cell or cluster of cells capable of developing into a new individual.
What is the origin of the word 'gemmule'?
- The word 'gemmule' originates from the Latin word 'gemmula', which means 'little bud' or 'small gem'. It was first used in English in the mid-19th century.
In what context is the word 'gemmule' typically used?
- The word 'gemmule' is typically used in the field of biology, specifically in reference to asexual reproduction in certain organisms.
Can 'gemmule' refer to both single cells and clusters of cells?
- Yes, 'gemmule' can refer to both a single cell or a cluster of cells that have the potential to develop into a new individual.
What organisms are known to produce gemmules?
- Sponges, specifically those in the class Calcarea, are known to produce gemmules as a means of asexual reproduction.
How do gemmules contribute to reproduction in sponges?
- Gemmules in sponges are formed by the aggregation of specialized cells that contain all the necessary resources for survival. These gemmules can survive harsh conditions and can later develop into new sponge individuals when conditions become favorable.
Are gemmules a common mode of reproduction in organisms?
- Gemmules are not a common mode of reproduction in most organisms. They are primarily observed in sponges and a few other simple organisms.
What is the significance of gemmules in evolutionary biology?
- Gemmules have significance in evolutionary biology as they allow for the survival and dispersal of organisms in unfavorable conditions. They can act as dormant stages that protect genetic material and increase the chances of species survival.
Can gemmules differentiate into different types of cells?
- Yes, gemmules have the potential to differentiate into different types of cells, enabling the development of various tissues and organs in the new individual.
Are gemmules the same as spores?
- No, gemmules are different from spores. Spores are reproductive cells or structures produced by organisms like fungi and plants, while gemmules are specific to certain organisms such as sponges.
