Lesson Objectives

• Describe the Structures of Eukaryotic cells and their functions

• Describe Eukaryotic Life

The Domain Eukarya

• The third domain of life is eukarya

• Includes all organisms that are made up of eukaryotic cells

• Divided into four kingdoms

  • Fungi

  • Plants

  • Animals

  • Protists: Anything that doesn't fit in the other three kingdoms

Eukaryotic cells

• Eukaryotic Cells cells have a nucleus as well as some additional structures

  • Organelles: Different Structures in the cell that do different tasks

    • Surrounded by a membrane

  • They are larger than prokaryotic cells and on average measure 10 to 100 micrometers

    • Ostrich egg yolk is a single cell that measures 10-15 centimeters

• Eukaryotes: Organisms made of Eukaryotic Cells

  • It can be made up of one cell or many cells

Multiple Choice

What is the trait that determines if a cell is prokaryotic or eukaryotic?

• The Size of the Cell

• The Shape of the Cell

• The Presence of A Nucleus

• How Old the Cell is

Multiple Choice

Is the following a prokaryote or eukaryote: A Pepper plant

• Prokaryote

• Eukaryote

Multiple Choice

Is the following a prokaryote or eukaryote: The Bacteria that causes tuberculosis

• Prokaryote

• Eukaryote

Multiple Choice

Is the following a prokaryote or eukaryote: A humpback whale

• Prokaryote

• Eukaryote

Tour of Eukaryotic cells- The Cell Membrane

• Cell Membrane: The structure that separates the inside of the cell from the outside of the cell

  • Allows materials in and out of the cell

Eukaryotic cells- Cell Wall

• Cell wall: A Rigid permeable layer that surrounds the cell membrane in some cells

  • Found in:

    • Bacteria

    • Plants

    • Fungi

  • Not found in Animal Cells

Tour of Eukaryotic cells- Inside the Cell

• Cytoplasm: The portion of the cell inside the membrane that surrounds the nucleus

  • Made up of crisscrossed fibers called Cytoskeleton that help the cell hold its shape

  • Hold other organelles in place

Tour of Eukaryotic cells- Protein Synthesis

• Ribosomes: Organelles that assemble proteins for the cell

• Rough Endoplasmic Reticulum: Assembles proteins destined to go through the cell membrane

  • It has ribosomes inside of it

• Smooth Endoplasmic Reticulum: Assembles membranes and may perform functions in specialized cells

Tour of Eukaryotic cells- Storing and Processing

• Golgi Apparatus: Receives products from the endoplasmic reticulum and packages them for transport

  • The "post office" of the cell

• Lysosomes: Break down organic materials like damaged/worn-out organelles

• Vacuoles: sacs surrounded by the membrane that can store materials

Tour of Eukaryotic cells- Energy Organelles

• Mitochondria: Organelles that break down organic molecules to obtain energy in a form that cells can use

• Chloroplasts: capture energy from sunlight and use it to build organic molecules

  • Only found in plant cells

Multiple Choice

Which part of the cell holds organelles in place?

• The Nucleus

• The Cell Membrane

• The Cytoplasm

• The Mitochondria

• The Chloroplasts
