2 Plants can reproduce both Sexually and Asexually. Pictures: http://www.troy.k12.ny.u s/old%20sites/thsbiology /skinny/skinny_reproduct ion.html http://www.troy.k12.ny.u s/old%20sites/thsbiology /skinny/skinny_reproduct ion.html http://users.rcn.com/jki mball.ma.ultranet/Biolog yPages/A/AsexualReprod uction.html http://users.rcn.com/jki mball.ma.ultranet/Biolog yPages/A/AsexualReprod uction.html

3  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/D efinitions/Def-A/asexual_reproduction.html Picture: http://www.saburchill.com/ans02/chapters/chap051.html

4  Budding in hydra  Budding in yeast  Spore Formation in Bread Mould  Binary Fission in Bacteria  Vegetative propogation in potatoes, in strawberries etc…

5 Check out this link it will tell you all about budding in hydra: http://www.youtube.com/watch?v=a5oHMjGqjyo http://www.labtechi ndia.net/product/Bi ology/bl-83.jpeg

8 Pollination is the process by which pollen is transferred in plants. Thereby allowing Fertilization and sexual reproduction. Information: http://en.wikipedia.o rg/wiki/Pollination Picture: http://www.myschool house.com/courses/ C/2/Images/Bee- Flower.jpg

9  Fertilisation is the fusion of pollen grain nucleus and ovule nucleus. Picture: http://www.homedepotgarde nclub.com/media/300874/ls _bg_top9fruit_img9.jpg

10  There are 4 different of seed dispersal and they are:  Water  Wind  Explosion  Animals

11  Seeds which float are carried away by water. Information: http://www.zeph yrus.co.uk/Water dispersal.html Picture: http://rainforest - australia.com/pic s/Fruits21.jpg

12  Some seeds are carried to a new place by the wind. Information: http://www.zephyru s.co.uk/Winddispers al.html Picture: http://blog.lib.umn. edu/michaels/thurs aft/Wind%20Dispers al%20dn.JPG

13  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/st ories/green_plants/ex plode_pod.jpg

14  The animal eats the fruit but only the juicy part is digested. It also hooks on the animal. Information: http://www.zephyru s.co.uk/Animal%20 Dispersal.html Picture: http://www.field- studies- council.org/urbanec o/images/019- Merry.jpg

15  There are 2 kinds of seeds  Dicot Seed  Monocot Seed Picture: http://www.s proutpeople.c om/kids/imag es/seed.dicot. monocot.wht. big.gif

16 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

17  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. Information: http://library.thinkquest. org/3715/seeds.html Picture: http://www.ext.colostate. edu/mg/gardennotes/im ages/137-1.jpg

19  Germination of seeds is when the seeds grow into a plant. Picture: http://www.co coponics.co/w p- content/upload s/2011/02/ger mination.jpg
