Cell Biology: Overview

Module Overview
This module covers cell biology including the concepts of: cell theory, eukaryotic and prokaryotic cells, organelles of animal and plant cells, levels of organization, and specialized cells. Students will have the opportunity to guide their own learning through a variety of “learning objects” intended to provide critical thinking about and application of required science standards.

Keywords: animal cell, cell, cell theory, cell wall, chloroplast, chlorophyll, cytoplasm, cytoskeleton, cytosol, endoplasmic reticulum, eukaryotic, Golgi apparatus, lysosome, mitochondria, nucleolus, nucleus, organ, organelles, organism, organ system, plant cell, plasma membrane, prokaryotic, ribosome, tissue, vacuole

Subject TEKS:

• 6.12 (A) understand that all organisms are composed of one or more cells (MS-LS1-1 Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.)
• 6.12 (B) recognize that the presence of a nucleus is a key factor used to determine whether a cell is prokaryotic or eukaryotic
• 7.12 (C) recognize levels of organization in plants and animals, including cells, tissues, organs, organ systems, and organisms; (MS-LS1-3 Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.)
• 7.12 (D) differentiate between structure and function in plant and animal cell organelles, including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast, and vacuole; (MS-LS1-2 Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function; not to include biochemical functions)
• 7.12 (E) compare the functions of cell organelles to the functions of an organ system; and
• 7.12 (F) recognize the components of cell theory.

Grades: 6th – 8th
