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.
Most unicellular organisms, and a few multicellular organisms, use cell division to reproduce, in a process called asexual reproduction. In asexual reproduction, one organism produces one or more new organisms that are identical to itself and that live independently of it.he bud grows until it forms a complete or nearly complete new organism that is genetically identical to the parent. In some budding organisms, buds can form from any part of the body. In other organisms, buds can be produced only by specialized cells in particular parts of the body.
