/. #eproduction

a) 0ife,cycle reproduction. 0iving things are referred to as organisms. 1very organism can reproduce or makean exact copy of itself. #eproduction is ordinarily referred to as the ability of an organism to produce anoffspring or baby ... be it an animal or plant. &his is more accurately called life,cycle reproduction becauseit refers to the stages in the life of a developing organism. 0ife,cycle reproduction ensures the propagationand preservation of species.

b) Cellular reproduction. 0ife cycle reproduction is possible because living things are made up of cells ... andcells have the ability to multiply by 2a3 splitting into two identical parts and 2b3 4oining together and form anew cell of the same kind. &he ability of cells to reproduce is known as cellular reproduction. &he cellular

reproduction of a single,celled organism is e5uivalent to its life,cycle reproduction.c) 6olecular reproduction. Cellular reproduction is possible because every cell contains a number of

molecules called D7A that have the ability to multiply by splitting into two identical parts. &his is known asmolecular reproduction.

8. &ypes of 0ife,Cycle #eproduction.

a) In asexual reproduction a part of the organism breaks off from which a new organism grows and develop.(ome plants and single,celled organisms reproduce asexually.

b) In sexual reproduction two sex cells from the same kind of organism are needed to produce an offspring.&he D7A of each sex cell 4oins together to produce a single new cell. &his new cell undergoes cellularreproduction and grows into a new organism. Animals and flowering plants reproduce sexually.

9. (exual #eproduction in Animals. &wo parents are needed in the sexual reproduction of animals: male andfemale.a3 hen the male sex cell or sperm of an animal 4oins with the female sex cell or egg of another animal of

the same kind a new cell called ygote is formed. &he union of the egg and sperm cells is known asfertiliation.

b3 As the ygote multiplies into more and more cells a new animal of the same kind grows. &he new animaldevelops from an embryo to a fully formed offspring. &his means that a baby animal can only come fromtwo grown,up animals like itself. A baby cat comes from a male and female cat; a baby dog comes from amale and female dog; a baby bird comes from a male and female bird.

1. #otivation

Which came first: the chicken or the egg?This is one question that science will never be able to answer with absolute certainty. That is why we call it a life cycle. A

cycle (from the Latin wor cyclusforcircle) has no efinite beginning or en.

2. Presentation

!erha"s a sim"ler question woul be: Where i the chicken come from? #n general$ where i organisms come from?All living things on %arth are calle organisms& whether they are the single'celle organisms or the multicellular

organisms such as "lants an animals. All organisms come from other organisms of their own kin. .. a "rocess callere"rouction.

3. Concept *ormation

. "en your books to "age *+. What is re"rouction?,. The more accurate term for re"rouction of organisms is life'cycle re"rouction because it refers to the stages in the life of

a evelo"ing organism. What oes life'cycle re"rouction ensure?-. Life cycle re"rouction is "ossible because living things are mae u" of cells. A cell can be com"are to every single

hollow block that makes u" a builing. #n other wors$ an organism can re"rouce because a cell can re"rouce. What arethe two ways of cellular re"rouction? (how vieo cli" of cellular re"rouction)

*. /ellular re"rouction is "ossible because every cell contains certain molecules that have the ability to multi"ly by s"littinginto two ientical "arts. What are these molecules calle?

0. Who can give the full name of 12A? (Deoxyribonucleic acid)

+. What is the re"rouction of 12A calle?3. Again$ why can organisms re"rouce? (Organisms can reproduce because they are made up of cells that contain DNA

molecules that can split into identical copies.)4. There are two ty"es of life cycle re"rouction of organisms: se5ual an ase5ual. What is se5ual re"rouction?6. Ase5ual means 7not se5ual8 or no se5 cells are involve. What kin of organisms re"rouce by ase5ual re"rouction?9. What ha""ens in ase5ual re"rouction?. What organisms re"rouce by se5ual re"rouction?,. What ha""ens in se5ual re"rouction?-. Why oes a ygote have the characteristics of the original s"erm cell an egg cell?*. #n your first activity$ you will escribe in etail the life cycle re"rouction of a chicken by using the iagram on "age *3.0. (Allow 9 minutes for the "u"ils to write a escri"tion of the iagram. Then call for a few volunteers to rea their

escri"tions.)+. Turn to "age *4. Two "arents are neee in the se5ual re"rouction of animals: male an female. #n the case of the chicken$

what are the two "arents?3. When the rooster;s se5 cell$ or s"erm$ ow o organisms re"rouce?What makes life cycle re"rouction of organisms "ossible?>ow o animals re"rouce?

6. Application)Integration

Good deeds reproduce in much the same way as organisms. One good deed one day at a time is what the world needs tobe a peaceful and happy place for all men. If you do good to your fellowmen, without expecting anything in return, be sure hewill do the same to his fellowmen...because a good deed is very contagious. It is interesting ho one cell can evolve into an animal through cellular reproduction! "hat is ho e build our reputation!

People ill #no us$ not by one heroic stro#e of luc#$ but by one action at a time everyday in our entire life!
