Mar 06, 2013 - 4:55 pm. I finished chemotherapy therapy in September for stage !V colon cancer. I had my second CT scan last Monday and the Onc called today and left a message that I still have a tiny spot on my lung and two very small cysts on my liver. What alarmed me was the word still. I had never heard before today that I had ANY spots or cysts found on my previous scan. Needless to say...I was a little freaked out.
Spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new sporophyte.
Upon germination, metabolic acitivity increases and a germ tube emerges from the spore. Key Concepts: Fungal spores have a unique role in fungal life cycles as they provide the genetic link between one generation and another. Spores can be part of asexual or sexual reproductive cycles, and are sometimes borne by multicellular sporocarps. Spores in part owe their success to their thick walls, reserve energy source, low metabolic rate and ability to withstand environmental stress that enables them to survive during dispersal.
