EOC and *Local Items
EOC Items
3.1.B: a. Recognize cells both increase in number and
differentiate, becoming specialized in structure and function,
during and after embryonic development DOK: 1
3.1.C: b. Describe the structure of cell parts (e.g., cell wall, cell
membrane, cytoplasm, nucleus, chloroplast, mitochondrion,
ribosome, vacuole) found in different types of cells (e.g.,
bacterial, plant, skin, nerve, blood, muscle) and the functions
they perform (e.g., structural support, transport of materials,
storage of genetic information, photosynthesis and respiration,
synthesis of new molecules, waste disposal) that are necessary to
the survival of the cell and organism DOK: 2
3.2.A: c. Explain physical and chemical interactions that occur
between organelles (e.g. nucleus, cell membrane, chloroplast,
mitochondrion, ribosome) as they carry out life processes DOK:
2
3.2.F: a. Explain the significance of the selectively permeable
membrane to the transport of molecules DOK: 2
3.2.F: b. Predict the movement of molecules across a selectively
permeable membrane (i.e., diffusion, osmosis, active transport)
needed for a cell to maintain homeostasis given concentration
gradients and different sizes of molecules DOK: 2
3.3.C: a. Recognize the chromosomes of daughter cells, formed
through the processes of asexual reproduction and mitosis, the
formation of somatic (body) cells in multicellular organisms, are
identical to the chromosomes of the parent cell DOK: 1
3.3.C: b. Recognize that during meiosis, the formation of sex
cells, chromosomes are reduced to half the number present in the
parent cell DOK: 1
3.3.C: c. Explain how fertilization restores the diploid number of
chromosomes DOK: 2
3.3.D: a. Describe the advantages and disadvantages of asexual
and sexual reproduction with regard to variation within a
population DOK: 2
Local Assessment Items
3.1.B: b. * Identify factors (e.g., biochemical, temperature) that
may affect the differentiation of cells and the development of an
organism DOK: 1
3.1.C: a. * Recognize all organisms are composed of cells, the
fundamental units of structure and function DOK: 1
3.2.A: a. *Compare and contrast the structure and function of
mitochondria and chloroplasts DOK: 2
3.2.A: b. *Compare and contrast the structure and function of
cell wall and cell membranes DOK: 2
3.3.A: a.* Distinguish between asexual (i.e., binary fission,
budding, cloning) and sexual reproduction DOK: 1
