To solve this problem, we need to identify the asexual reproductive structure associated with $Penicillium. \newline$Let's analyze the options provided:$\newline$• Option 1: Zoospores$\newline$ - Zoospores are motile asexual spores found in some algae and fungi, but not in $\textit{Penicillium}. \newline$• Option 2: Conidia$\newline$ - Conidia are asexual, non-motile spores that are produced by fungi like $\textit{Penicillium}. \newline$ - These spores are formed at the tips of specialized hyphae called conidiophores.$\newline$• Option 3: Gemmules$\newline$ - Gemmules are asexual reproductive structures found in sponges, not in fungi.$\newline$• Option 4: Buds$\newline$ - Budding is a form of asexual reproduction seen in yeast and some other organisms, but not in $\textit{Penicillium}. \newline$Based on the above analysis, the correct asexual reproductive structure associated with $\textit{Penicillium}$ is conidia.$\newline$Therefore, the correct option is Option 2.
