All living things are made up of one or more cells. Cells come in a variety of shapes and sizes that suit their diverse functions. Cell membranes help organisms maintain homeostasis by controlling what substances enter or leave cells.
How can we describe the relationship between structure and function in prokaryotic and eukaryotic cells?
Cell Structure and Function SC.912.L.14.3 SC.912.L.14.2
LEQ: Number 1: What is the relationship between the structure and function of the major cell organelles found in a eukaryotic cell? •
Structures include: cytoplasm, nucleus, nucleolus, nuclear envelope, cell membrane, mitochondria, Golgi bodies, vacuole, centrioles, ribosomes, and endoplasmic reticulum (smooth and rough) •
Exclusive to plants: chloroplasts, central vacuole, cellulose cell wall •
Exclusive to animals: lysosome, centrioles
Compare and contrast plant and animal cell structures
Special structures include; cilia and flagella
LEQ: Number 2: What similarities and differences exist between prokaryotic and eukaryotic cells? •
Commonalities: cell wall (plants & fungus), cell membrane, ribosomes, cytoplasm, chromosomes •
Differences: nucleus, nucleolus, membranes, structure of cell wall, arrangement of chromosomes (ring in prokaryote with little protein vs. rods in eukaryotes with proteins) •
Eukaryotes : Protista, Fungi, Plantae, Animalia
Prokaryotes: Eubacteria, Archaebacteria
Eukaryote, prokaryote, organelle
Cell Transport SC.912.L.14.2
LEQ: Number 1: How does the cell membrane regulate the movement of materials into and out of the cell? •
Structure of cell membrane and functions of the parts: phospholipid bilayer, cholesterol, integral proteins, peripheral proteins, carbohydrate markers.
LEQ: Number 2: How do concentration gradients impact the movement of materials across the cell membrane? •
Define the terms gradient, concentration...
