1. Asexual Vs. Sexual Reproduction
7th grade Science
SPI Compare and contrast the
fundamental features of sexual and asexual
reproduction.

2. Types of Asexual Reproduction

3. 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

4. Binary Fission The cell divides and separate creating a daughter cell
Examples are prokaryotes and bacteria cells

5. 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

6. Fragmentation A new organism grows from a fragment of the parent.
Examples are fungi, moss, sea stars, and planarians

7. 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?

8. Sexual Reproduction

9. 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

10. 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

11. 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?

12. Review Sexual Asexual Type of Reproduction Methods Advantages
Disadvantages
Sexual
Internal fertilization
Diversity in offspring
Offspring less likely to have mutations show up
Requires a mate to reproduce
Population increases are limited
External fertilization
Asexual
Budding
Can increase populations rapidly
Does not require a mate for reproduction to take place
Lack of diversity in offspring
Because they reproduce offspring genetically identical to parents, the offspring inherit any mutations of the parent.
Fragmentation
Binary Fission
