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.
Endospores can also be larger or smaller in diameter than the vegetative cell. Those that are larger in diameter will produce an area of swelling in the vegetative cell. These endospore characteristics are consistent within the spore-forming species and can be used to identify the organism.pores are resistant to heat, dessication, chemicals, and radiation. Bacteria can form endospores in approximately 6 to 8 hours after being exposed to adverse conditions. The normally-growing cell that forms the endospore is called a vegetative cell. Spores are metabolically inactive and dehydrated.
