CELLS 2.1 Cell Structure and Function- Pre AP Biology Study Notes – New Syllabus.
LEARNING OBJECTIVE
CELLS 2.1(a) Provide evidence to support the claim that all biological systems demonstrate some shared characteristics.
CELLS 2.2(a) Develop and/or use models to compare and contrast cell structures of different cells.
Key Concepts:
CELLS 2.1.1 The cell is the basic unit of biological systems, and there are some shared characteristics among all cells.
a. All cells possess a plasma membrane, ribosomes, genetic material, and cytoplasm.
b. All cells result from the division of preexisting cells.CELLS 2.2.1 Cells have specialized structures that perform specific functions.
a. Some cells (eukaryotes) have a nucleus that houses their DNA.
b. Cell structures can be organized based on four primary functions:
1. Energy transfer (e.g., chloroplasts, mitochondria).
2. Production of proteins (e.g., ribosomes, ER, Golgi apparatus).
3. Storage and recycling of materials (e.g., lysosomes, vacuoles, vesicles).
4. Support and movement (e.g., cell walls, cytoskeleton, flagella).
