Dive deep into the world of cells with this detailed exploration of their structures, functions, and types. Learn about prokaryotic and eukaryotic cells, mitochondria, chloroplasts, endosymbiosis, and different cell features. Compare animal and plant cells, cell membranes, cell walls, ER functions, and more. Discover the Kingdoms of life, including Protists, Fungi, Plantae, and Animalia. Sharpen your knowledge on the smallest units of life with this educational resource.

CELLS Structure and Function Cell = smallest unit of life
Cell Theory • 1. Cells are the smallest unit of life. • 2. All living things are made of cells. • 3. All cells arise from other cells.
Turn to your neighbor…… • Which of these 3 parts can you relate to the characteristics of life?
Features of Prokaryotic Cells All prokaryotic cells contain
Features of Prokaryotic Cells Other possible prokaryotic structures
Features of Prokaryotic Cells Other possible prokaryotic structures
Kingdoms that are Prokaryotic • Archaea • Eubacteria
Endosymbiosis • Endosymbiotic Theory: • Mitochondria and chloroplasts were thought to have been free- living prokaryotic cells • These structures were taken in by a eukaryotic cell, became useful to the cell metabolism and were retained as organelles • Evidence: • Both mitochondria and chloroplasts have: • 70s ribosomes • Own DNA • Ability to reproduce independently from the cell • Double membrane on outside • Same size as prokaryotic cells
Turn to your neighbor…… • Compare the mitochondria to the chloroplast.
Eukaryotic Cell (protist, animal)
Discuss the differences between prokaryotic and eukaryotic cells.
Eukaryotic Cell (plant)
Turn to your neighbor: • Compare the structure of the cell membrane to the structure of the cell wall.
SER Functions of Eukaryotic Cell Features RER
Turn to your neighbor…… • Compare the function of the E.R. with the function of the Golgi.

Kingdoms that are Eukaryotic • Protists: • Eukaryotic • Some have cell walls, but some don’t • Contain uni- and multicellular organisms • Some are autotrophic and some are heterotrophic • Only characteristic they have in common is they are all eukaryotic
Eukaryotic Kingdoms, cont. • Fungi • Contains mushrooms, yeast, mold and mildew • Eukaryotic • Have cell walls made of chitin • Yeast are unicellular; all others are multicellular • Heterotrophic – absorptive
Eukaryotic Kingdoms, cont. • Plantae: • Includes all the plants • Eukaryotic • Have cell walls made of cellulose • Multicellular • Autotrophic • Contain chloroplasts
Eukaryotic Kingdoms, cont. • Animalia: • Eukaryotic • No cell walls • Multicellular • Heterotrophic • Only Kingdom with NO cell walls
