MYP Biology Year 11 Sexual and Asexual Reproduction Name:_______________ 1 Objective • • Describe the differences between sexual and asexual reproduction Describe sexual reproduction and fertilization as the fusion of the nucleus of the egg and sperm cell Key Terms Asexual reproduction Sexual reproduction Clone Vegetative Stolen Runner Tuber Fission Budding Gamete Fertilisation Binary Fission Fragmentation Mitosis Plantlets Cuttings Tissue culture Offspring Reproduction 2 1. When an organism reproduces they themselves. It means making a of itself. It is not necessary for an individual organisms to .Some organisms reproduce . Cows make more cows and pigs make more pigs. This form of reproduction combines genes from a mother and a father, making a genetically organism. 2. Other organisms reproduce . In these organisms all the genes come from a ________ parent. Asexually produced offspring are genetically __________ to the parent. Asexual Reproduction 1. Asexual only requires parent. Offspring have chromosomes as the parent..Offspring are Reproduction is found mostly in organisms . growth and development 2. There are many methods of asexual reproduction. In some single-celled organisms, _________________ is a method of asexual reproduction. This is a process where the cell divides into nearly equal sized Bacteria cells reproduce through cell division. The cell makes a copy of its then sends the copy into a new bacteria cell. Some bacteria cells can reproduce fast, making a new cell every 20 minutes. 3. Another method of asexual reproduction is known as . It used in plants 4. Another method of asexual reproduction is budding. Unicellular yeast cells grow new cells off of the of a parent. When the cell is developed it falls off and a new ________ cell is produced. 5. Some organisms produce offspring by splitting into pieces. This is called .A sea anemone can split down the middle and 3 the same of the parent. the for form of . This is also or produce into another individual _________ to the original. Some worms if split will continue to live as identical worms. 6. Some organisms like the starfish and the salamander can replace an injured or lost part. This is called . Many plants are capable of 7. List examples of organisms that reproduce asexually 8. List the advantages of asexual reproduction Sexual Reproduction 1. Sexual reproduction requires that share the genetic information. Offspring share the characteristics of each 4 of . This process is accomplished through the cell division called 2. 3. 4. List examples of organisms that reproduce sexually List the two ways Sexual reproduction occurs.
