Content Objective
Students will demonstrate knowledge of the concepts of heredity by watching video clips and taking notes.
L.HE.M.2 Reproduction- Reproduction is a characteristic of all living systems; because no individual organism lives forever, reproduction is essential to the continuation of every species. Some organisms reproduce asexually. Other organisms reproduce sexually.
L.HE.07.21 Compare how characteristics of living things are passed on through generations, both asexually and sexually.
L.HE.07.22 Compare and contrast the advantages and disadvantages of sexual vs. asexual reproduction.
Language Objective
Students will write to describe the concepts of heredity by correcting their answers by comparing with the answer key:
1.Reproduction is the process by which organisms make more of their own species.
2.Reproduction may not be important to an individual organisms survival, but it is very important to the survival of a species because the species would go extinct without it.
3.Characteristics are passed on through generations through genes/DNA found in chromosomes.
4.There are two main type of reproduction Sexual and Asexual.
5.Asexual reproduction requires only one parent. It occurs when the parent organism divides to form two new organisms.
6.Sexual reproduction requires two parents. It occurs when the egg cell and sperm cell join.
7.Sexual reproduction produces offspring that are unique (different from all other organisms). This is because they get their DNA from two different parents.
8.Asexual reproduction produces offspring that are identical (exactly the same) as the parent. This is because they get their DNA from only one parent.
9.Benefits of Asexual(one parent) reproduction include many offspring can be created in a very short period of time and organisms do not need to spend time and energy looking for a mate.
10.Benefits of Sexual(two parent) reproduction include the species goes through constant change because new DNA is being mixed all the time and this allows the species to better adapt to changes in it’s environment.
