Asexual Vs. Sexual Reproduction 7th grade Science SPI 07.07. 4.1 Compare and contrast the fundamental features of sexual and asexual reproduction.
What is Asexual Reproduction • Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only • Primary form of reproduction for single-celled organisms • Shorter life span • Grows very rapidly • Contains one parent • Identical to the parent
Binary Fission The cell divides and separate creating a daughter cell Examples are prokaryotes and bacteria cells
Budding The buds grow into fully matured individuals which eventually break away from the parent organism. Examples are yeast, sponges, corals, jelly fish and hydras
Fragmentation A new organism grows from a fragment of the parent. Examples are fungi, moss, sea stars, and planarians
Asexual Question • What are some animals that go through asexual reproduction? • How many parents are involved with asexually reproduction? • What do the offspring look like in asexual reproduction? • What are some advantages of reproducing asexually? • What are some disadvantages of reproduction asexually?
What is Sexually Reproduction • Sexual reproduction is the creation of a new organism by combining the genetic material of two organisms. • Requires two sex cells – egg and sperm • The egg and sperm join to form an entirely new organism • Longer life span • Takes longer to grow • Contains two parents • Different from the parent • Goes through the process of meiosis
Examples of Sexual Reproduction Plants- Pollen is delivered to female part of the plant Insects Humans- DNA from 2 individuals merge to form one Animals- Internal or External merge of DNA to form one
Sexual Questions • What are some animals that go through sexual reproduction? • How many parents are involved with sexually reproduction? • What do the offspring look like in sexual reproduction? • What are some advantages of reproducing sexually? • What are some disadvantages of reproduction sexually?
