| C2a* 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. | 7.2a. the differences between the life cycles and reproduction of sexual and asexual organisms. | Content Standard 13 (partial): Students understand that some living things reproduce asexually and/or sexually. Sexual reproduction results in a variety of individuals because the genetic material from each parent combines to form variations within offspring. |
| C2b* In many species, including humans, females produce eggs and males produce sperm. Plants also reproduce sexually--the egg and sperm are produced in the flowers of flowering plants. An egg and sperm unite to begin development of a new individual. That new individual receives genetic information from its mother (via the egg) and its father (via the sperm). Sexually produced offspring never are identical to either of their parents. | 7.2b. sexual reproduction produces offspring that inherit half their
genes from each parent.
7.5d. how the reproductive organs of the human female and male generate eggs and sperm, and how sexual activity may lead to fertilization and pregnancy. 7.5f. the structures and processes by which flowering plants generate pollen and ovules, seeds, and fruit. |
Content Standard 13 (partial): Students understand that some living things reproduce asexually and/or sexually. Sexual reproduction results in a variety of individuals because the genetic material from each parent combines to form variations within offspring. |
| C2c* Every organism requires a set of instructions for specifying its traits. Heredity is the passage of these instructions from one generation to another. | NOT PRESENT IN CA STATE STANDARDS | NOT PRESENT IN SFUSD STANDARDS |
| C2d* Hereditary information is contained in genes, located in the chromosomes of each cell. Each gene carries a single unit of information. An inherited trait of an individual can be determined by one or by many genes, and a single gene can influence more than one trait. A human cell contains many thousands of different genes. | 7.2c. an inherited trait can be determined by one or more genes.
7.2d. plant and animal cells contain many thousands of different genes, and typically have two copies of every gene.....(partial) |
NOT PRESENT IN SFUSD STANDARDS |
| C2e* The characteristics of an organism can be described in terms of a combination of traits. Some traits are inherited and others result from interactions with the environment. | 7.2. A typical cell of any organism contains genetic instructions that specify its traits. Those traits may be modified by environmental influences. | NOT PRESENT IN SFUSD STANDARDS |
| NOT PRESENT IN NATIONAL STDS | 7.2d. (partial)...The two copies (or alleles) of the gene may or may
not be identical, and one may be dominant in determining the phenotype
while the other is recessive.
7.2e. DNA is the genetic material of living organisms, and is located in the chromosomes of each cell. 7.5e. the function of the umbilicus and placenta during pregnancy. |
