Hellooooo, today i'm here to talk about mycology. (as usual. tsk.) It is actually a fasicinating subject if you are interested.
I'm here today to talk about the structures and lifestyle of the fungi.
Cell wall-
Rigid cell wall provides support for the Protoplasm of the fungal cell. The fungal cell walls are mostly chitin and glucan, while plant cell walls are mostly cellulose, plus liginin in the secondary walls.
Fungi are actually more alike animals than plants. Plants can make their own food through photosynthesis, while fungi cannot do so.
Fungi obtain their food via external digestion. They produce exoenzymes to digest food. They secrete them onto the surface which they are growing to digest their food. The fungi then absorbs the nutrients via the mycelia.
The fungi would then store their food as glycogen, just like animals!
Fungi however, has a lifestyle totally unique to its own kind.
Fungi are not dependent on light, and can occupy dark habitats. They also can grow in any direction. This is unlike animals and plants which require light!
Fungi can also invade the interior of the substrate with absorptive filaments!
Thats it for today, stop complaining! its already over :P
