  1. Notes on Reproduction By: Dhikshitha 7E

  2. Sexual Reproduction. • Asexual Reproduction. Plants can Reproduce in 2 ways. http://www.targetcbse.co.in/LMSM/file.php/1/polncycl.gif http://www.saburchill.com/ans02/images2/210807004.jpg

  3. Asexual Reproduction • Asexual reproduction is the formation of new individuals from the cell(s) of a single parent. It is common in plants than in animals. http://www.education.com/science-fair/article/asexual-reproduction/

  4. Examples of Asexual Reproduction • Budding in Hydra. • Budding in yeast • spore formation in bread mould. • Binary Fission in Bacteria • Vegetative probation in potatoes in strawberries etc.

  5. Budding in Hydra. Budding in hydra. As you can see in the image budding in hydra is when a small bud grows and starts to develop. http://www.labtechindia.net/product/Biology/bl-83.jpeg Here is a youtube video that explains more about budding in hydra. http://www.youtube.com/watch?v=a5oHMjGqjyo

  6. Binary Fission in Bacteria Binary Fission in Bacteria is when the parent enlarges (grows) and duplicates it’s DNA. In other words I splits into 2. http://iws.collin.edu/biopage/faculty/mcculloch/1406/outlines/chapter%2011/11-2.JPG

  7. Sexual Reproduction Plants can be Uni sexual or Bisexual • Female • Stigma • Style • Ovary • Ovules http://www.mendelweb.org/MWflower.html

  8. Pollination It can happen in many ways: Bees: When bees take nectar from plants the pollen sticks on them. And when they sit on another flower the pollen wares off. Air: Pollen may move in the direction on the wind and fall on other flowers. Pollination is when pollen is transferred form one plant to another and enables the fertilization and sexual reproduction. http://www.theairquality.com/wp-content/uploads/2010/05/bee-collecting-pollen.jpg http://www.treehugger.com/pollen-helps-allergies-phot.jpg

  9. Fertilization • Fertilization is the fusion of pollen grain nucleus and ovule nucleus. http://www.school.net.th/library/create-web/10000/science/10000-6584/pic1.jpeg

  10. Seed Dispersal Seed Dispersal can happen in 4 different ways. • Air • Water • Animals • Exploding flowers

  11. Seed dispersal through air. • The lighter seeds can be carried to different places by air. http://researchfacility.files.wordpress.com/2010/09/alsomitramacrocarpa.jpg http://passionforeducating.com/yahoo_site_admin/assets/images/Picture14.47125647_std.png

  12. Seed Dispersal Through Water • If the plant was next to a body of water, there are chances that the seed would fall in the water. It will move to a far away place according to the movement of the water. http://web1.stmaryssen-h.schools.nsw.edu.au/SMSHS/ricks%20sites/Biology%20web%20site/Pre_8_5_Evolution%20of%20Australian%20Biota/Seed%20dispersal/Seed%20Dispersal%20prac/bladed-seeds.jpg

  13. Seed Dispersal Through Animals • When animals like squirrels find a fruit thy take it to different places and eat it. They do not eat the seed, so they spit it out. http://4.bp.blogspot.com/_PuCt7OSC9iM/Sc6101DoLsI/AAAAAAAAAD8/hPn4YGntDb8/s400/squirrel.jpg

  14. Seed Dispersal Through Animals • Some seed have hook like ends. When animals run past them they hook to their fur. As the animals run the seeds fall off. http://media.spokesman.com/photos/2011/02/04/SRX_dogpark_5_t400.jpg?fd5af0684d698ce74dd4392bafb4f89a6dc66ee3

  15. Seeds Dispersal though exploding fruits • Particular fruits explode when they get ripe. The shoot out their seeds and the seeds fall in different places. http://biologylabs.utah.edu/bohs/IMAGES/Stephen%20Stern/S%20turneroides-ssm.jpg

  16. Seeds • There are 2 different types of seeds Dicot Seeds Monocot Seeds http://www2.yk.psu.edu/~sg3/ist311/games/team3/images/seeds.png

  17. Dicot Seeds • Dicot Seeds are seeds that be spit in half. They are made of two pieces. http://www2.estrellamountain.edu/faculty/farabee/biobk/dicotseed.gif

  18. Monocot Seeds • Monocot seeds cannot be split into half. It is made of 1 piece. http://3.bp.blogspot.com/_NfIGV0h1wfI/Rw7Fqnr4drI/AAAAAAAAABE/fZt-GwtNSZY/s400/cornkernel.gif

  19. Germination Germination in the name of the process in which a seed grows into a plant. • Conditions need for germination • Air • Sunlight • Soil • Water http://scienceinhydroponics.com/wp-content/uploads/image-import/_uEJxElFqOmc/THML1zEnCLI/AAAAAAAAA5c/UFl3w09uwYI/s1600/germination.jpg
