    • UT.7.II.2.d Distinguish between models of Earth with accurate and inaccurate attributes.

UT.7.III. Students will understand that the organs in an organism are made of cells that have structures and perform specific life functions.

  • UT.7.III.1. Observe and describe cellular structures and functions.

    • UT.7.III.1.a Use appropriate instruments to observe, describe, and compare various types of cells (e.g., onion, diatoms).

    • UT.7.III.1.b Observe and distinguish the cell wall, cell membrane, nucleus, chloroplast, and cytoplasm of cells.

UT.7.IV. Students will understand that offspring inherit traits that make them more or less suitable to survive in the environment.

  • UT.7.IV.1. Compare how sexual and asexual reproduction passes genetic information from parent to offspring.

    • UT.7.IV.1.a Distinguish between inherited and acquired traits.

    • UT.7.IV.1.b Contrast the exchange of genetic information in sexual and asexual reproduction (e.g., number of parents, variation of genetic material).

    • UT.7.IV.1.c Cite examples of organisms that reproduce sexually (e.g., rats, mosquitoes, salmon, sunflowers) and those that reproduce asexually (e.g., hydra, planaria, bacteria, fungi, cuttings from house plants).
