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.lant spores are produced by the organisms we can usually recognize. The major types of plants that form spores are algae, mosses, and ferns. Algae are the simplest of these plants, and can range from tiny, single celled things to large, multi-celled plants that cover your backyard pond.
