Spicules refers to structures found in sponge skeletal structures. They are composed of calcium carbonate and are calcareous. They are chalky in their nature. The layers of silicon make up some of the sponges’ spicules, which makes them siliceous.
Why do Gemmules form?
A Gemmule is an asexually created mass of cells that are capable of growing into new organisms or becoming adult freshwater sponges. These are tiny, bud-like cells that are created by sponges to withstand adverse environmental conditions.
What are Gemmules and conidia?
Solution. Gemmule-asexual reproduction structure in SQPonges. Penicillium: Conidia-asexual reproductive system. (or any other correct )
How are conidia formed?
After a period,
Conidia form. To this end, specialized aerial hyphae differentiate into conidiophores (Adams et al., 1998). These stalks extend about 100-3000 mm into the air, after which a so-called vesicle is formed by swelling of the hyphal tip.
