Identification of Slides
a) Penicillium - Structure
Identification - The given slide is identified as Penicillium - a fungus, Vegetative structure.
Reasons for identification:
1. The plant body of penicillium is called mycelium.
2. Mycelium consists of thread like structures called hypha.

4. The cytoplasm consists of a nucleus, organelles like mitochondria, golgi body, ribosomes, etc.
5. It is commonly known as green or blue mould.
Refer Fig 1.6 (Only Thallus) given below:
b) Penicillium - Asexual reproduction
Identification - The given slide is identified as Penicillium -Asexual reproduction
Reasons for identification :
1. Penicillium reproduces asexually by production of spores called . conidia.
2. Some of the hyphae grow vertically and are called conidiophore.
3. The conidiophore bears a terminal cluster of flask like structures called sterigmata.
