Standard - MST4: Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.
Key Idea Code - MST4.LE:
Key Idea - MST4.LE1: Living things are both similar to and different from each other and from nonliving things.
Academic Level - MST4.I.LE1:
Performance Indicator - MST4.I.LE1A: Students compare and contrast the parts of plants, animals, and one-celled organisms.
Major Understandings - 1.1a : Living things are composed of cells. Cells provide structure and carry on major functions to sustain life. Cells are usually microscopic in size.
Major Understandings - 1.1b : The way in which cells function is similar in all living things. Cells grow and divide, producing more cells. Cells take in nutrients, which they use to provide energy for the work that cells do and to make the materials that a cell or an organism needs.
Major Understandings - 1.1c : Most cells have cell membranes, genetic material, and cytoplasm. Some cells have a cell wall and/or chloroplasts. Many cells have a nucleus.
Major Understandings - 1.1d : Some organisms are single cells; others, including humans, are multicellular.
Major Understandings - 1.1e : Cells are organized for more effective functioning in multicellular organisms. Levels of organization for structure and function of a multicellular organism include cells, tissues, organs, and organ systems.
Major Understandings - 1.1f : Many plants have roots, stems, leaves, and reproductive structures. These organized groups of tissues are responsible for a plant's life activities.
Major Understandings - 1.1g : Multicellular animals often have similar organs and specialized systems for carrying out major life activities.
Major Understandings - 1.1h : Living things are classified by shared characteristics on the cellular and organism level. In classifying organisms, biologists consider details of internal and external structures. Biological classification systems are arranged from general (kingdom) to specific (species).
