Eukaryotic cells are complex cells that make up plants, animals, fungi, and protists. Unlike prokaryotic cells, eukaryotic cells have a true nucleus and membrane-bound organelles.

Characteristics of Eukaryotic Cells:

Nucleus: Eukaryotic cells have a distinct nucleus that houses the genetic material (DNA) enclosed within a nuclear membrane.
Membrane-bound Organelles: Eukaryotic cells contain various membrane-bound organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and chloroplasts (in plant cells).
Complex Structure: Eukaryotic cells are structurally complex, with internal compartments that carry out specific functions.
Cellular Division: Eukaryotic cells undergo mitosis for growth and repair, and meiosis for sexual reproduction.
Size: Eukaryotic cells are generally larger than prokaryotic cells, ranging from 10 to 100 micrometers in diameter.

Eukaryotic Cell Organelles:

Eukaryotic cells contain various organelles that perform specific functions within the cell:

Mitochondria: Powerhouse of the cell, involved in cellular respiration and energy production.
Endoplasmic Reticulum (ER): Involved in protein and lipid synthesis.
Golgi Apparatus: Modifies, sorts, and packages proteins for secretion.
Lysosomes: Contain digestive enzymes for breaking down waste materials.
Chloroplasts: Found in plant cells, involved in photosynthesis and contain chlorophyll.

Study Guide:

Use the following questions to test your understanding of eukaryotic cells:

What is the main difference between eukaryotic and prokaryotic cells?
List three membrane-bound organelles found in eukaryotic cells and describe their functions.
How does cellular division occur in eukaryotic cells?
Compare the size of eukaryotic cells to prokaryotic cells.
Explain the role of mitochondria in eukaryotic cells.

LIFE SCIENCE

From Molecules to Organisms: Structures and Processes

Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.

Unity and Diversity

Analyze and interpret data from fossils (e.g., type, size, distribution) to provide evidence of organisms and the environments in which they lived long ago (e.g., marine fossils on dry land, tropical plant fossils in arctic areas, fossils of extinct organisms in any environment).
