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.
Spores are the reproductive structure of the 'lower plants,' plants that don't flower. Fungi, algae, and even some bacteria all form spores when they want to pass their genes on.pores are single-celled reproductive units produced by many different organisms, including plants, fungi, and bacteria. Spores are primarily used for asexual reproduction, although some bacterial groups use spores to survive harsh conditions.
