Bacteria, Protists, Fungi and Animals Asexual Reproduction Bacteria, Protists, Fungi and Animals

Imagine the possiblities if you could make an identical you in 20 minutes

Asexual Reproduction Asexual reproduction is the formation of a new individual that has identical genetic information to its parent - (ie cloning-if we made another one of ourselves like in sci-fi movies)

Life’s Five Kingdoms Monera Protista Fungi Plant Animal

Life’s Five Kingdoms Monera Protista Fungi Plant Animal Type of cells Prokaryotic Eukaryotic # of cells One-celled One & many celled Many celled Movement Some move Do not move Move Nutrition Some make their own food, others obtain from other organisms All members obtain food from other organisms Members make their own food Members eat plants or other organisms

Monera Bacteria is an example of the Monera kingdom, it is a uni-cellular (one-celled) organism that does not have a true nucleus. Bacteria reproduces asexually through a process called binary fission. Binary Fission is the process of the parent cell dividing, so that each new cell contains a single chromosome, carrying a complete set of DNA identical to the parent. It takes 20 min total (imagine me replicating myself in the 1st 20 min of class, you would have two of me to go around and answer questions).

Protista Amoeba, member of the Protista family, relies on asexual reproduction, however unlike bacteria, the DNA of a Protista is in a true nucleus. They transform through mitotic cell division. (MITOSIS) Protista forms the basis of most food chains and are responsible for many diseases that affect humans

Fungi You ate a fungus last night in the form of mushrooms on your pizza. It was made of thin layer or filaments called hyphae and it grew over the surface (soil) and in the bodies of other organisms (compost) to obtain food. Fungi reproduce in three different ways: through the process of fragmentation, budding and spores.

Reproduction in Fungi Fragmentation—A small piece or fragment, breaks away from the main mass of hyphae and grows into a new individual Budding—A copy of the nucleus is made first, then a tiny bud begins to form on the cell wall. This bud, containing the new nucleus, continues to grow larger, until it breaks away to become an independent cell. Spore—This is a reproductive cell that can grow into a new individual cell through miotic cell division. They are stored in a case called a sporangium. When mature they take on a characteristic colour such as black, yellow, blue or red.

Asexual Reproduction in Animals Two main groups— Vertebrates (backbones) Invertebrates (no backbones) Invertebrates make up 97% of all animal species Many invertebrates can reproduce asexually.

Asexual Reproductionin Animals - Planaria Planaria are a type of flat worm. They reproduce asexually by dividing in two and regenerating the parts they are missing. Part that retains the head grows a new tail. Part that retains the tail grows a new head.

Asexual Reproduction in Animals Some animals reproduce asexually by budding. A cell, usually near the base of the organism undergoes mitosis and cell division repeatedly to produce a new group of cells. When the bud has completed development it detaches as a new organism.
