Asexual Reproduction • Asexual reproduction means reproduction in which a cell doubles its contents and then divides into two identical cells. • Information: • http://groups.molbiosci.northwestern.edu/holmgren/Glossary/Definitions/Def-A/asexual_reproduction.html • Picture: • http://www.saburchill.com/ans02/chapters/chap051.html
Examples of Asexual reproduction • Budding in hydra • Budding in yeast • Spore Formation in Bread Mould • Binary Fission in Bacteria • Vegetative propogation in potatoes, in strawberries etc…
Budding in Hydra Check out this link it will tell you all about budding in hydra: http://www.youtube.com/watch?v=a5oHMjGqjyo http://www.labtechindia.net/product/Biology/bl-83.jpeg
Budding in Yeast Look at this diagram: Picture: http://www.fungionline.org.uk/images/1intro/yeast1.JPG
Pollination Pollination is the process by which pollen is transferred in plants. Thereby allowing Fertilization and sexual reproduction. Information: http://en.wikipedia.org/wiki/Pollination Picture: http://www.myschoolhouse.com/courses/C/2/Images/Bee-Flower.jpg
Fertilisation • Fertilisation is the fusion of pollen grain nucleus and ovule nucleus. Picture: http://www.homedepotgardenclub.com/media/300874/ls_bg_top9fruit_img9.jpg
Seed Dispersal • There are 4 different of seed dispersal and they are: • Water • Wind • Explosion • Animals
Water • Seeds which float are carried away by water. Information: http://www.zephyrus.co.uk/Waterdispersal.html Picture: http://rainforest-australia.com/pics/Fruits21.jpg
Wind • Some seeds are carried to a new place by the wind. Information: http://www.zephyrus.co.uk/Winddispersal.html Picture: http://blog.lib.umn.edu/michaels/thursaft/Wind%20Dispersal%20dn.JPG
Explosion • Some plants have pods that explode when ripe and shoot out the seeds. Information: http://www.zephyrus.co.uk/explosions.html Picture: http://www.gtchild.co.uk/content/images/stories/green_plants/explode_pod.jpg
Animals • The animal eats the fruit but only the juicy part is digested. It also hooks on the animal. Information: http://www.zephyrus.co.uk/Animal%20Dispersal.html Picture: http://www.field-studies-council.org/urbaneco/images/019-Merry.jpg
Seeds • There are 2 kinds of seeds • Dicot Seed • Monocot Seed Picture: http://www.sproutpeople.com/kids/images/seed.dicot.monocot.wht.big.gif
Dicot Seed A bean seed is a Dicot. • Seed coat • The bean seed has a split going down the middle of the seed. • The two large parts of the seeds are called cotyledons. Cotyledons supply food for the young plant as its growing. Information: http://library.thinkquest.org/3715/seeds.html Picture: http://library.thinkquest.org/3715/dicot.gif
Monocot Seed • Monocots are seeds that only have 1 cotyledon, such as the corn seed, The corn seed has a seed coat but it does not slip off as easily as the bean seed does. • It stays in one piece.

Conditions for germination of seeds. Air Water • Air • Water • Sunshine • Soil Sunshine Soil Air picture: http://eo.ucar.edu/kids/sky/images/air1_sm.jpg Water Picture: http://www.3dtexture.net/data/media/10/Fresh_water_ocean_texture.jpg Sunshine Picture: http://3.bp.blogspot.com/-lnEwRLYS4Po/TVvMVTzGXTI/AAAAAAAADPs/GQ8W2F8XXkE/s1600/sunshine1.jpg Soil picture: http://www.uvm.edu/~pss/HandsSoilPlant.jpg
Germination of Seeds • Germination of seeds is when the seeds grow into a plant. Picture: http://www.cocoponics.co/wp-content/uploads/2011/02/germination.jpg
