7. CELL STRUCTURE & FUNCTION
Chapter 4

8. THE DISCOVERY OF CELLS
Cells: is the smallest unit that can carry on all processes of life

9. ROBERT HOOKE
An English Scientist studied nature in using an early light microscope
Studied a thin slice of cork and viewed small cubicles or “cells”
He then studied tree stems, roots, and ferns and noticed they had the same structures

10. ANTON VAN LEEUWENHOEK First person to view living cells
His microscope was had 10x the magnification of Hooke’s microscope
1673, viewed the first Protists he called “animalcules”

11. THE CELL THEORY
Matthias Schleiden concluded plants were composed of cells
Theodor Schwann concluded animals were composed of cells
Rudolf Virchow noted that cells came from other cells
These theories were combined to form the basic components of the cell theory

12. THE CELL THEORY All living organisms are composed of one or more cells
Cells are the basic units of structure and function in an organisms
Cells come only from the reproduction of existing cells

13. CELLULAR BASICS OF LIFE
Microscopes help scientists clarify the definition of life
All living things have several basic characteristics:
Consist of organized parts
Obtain energy from their surroundings
Perform chemical reactions
Change with time
Respond to their environment
Reproduce

14. CELL SIZE Why is this important????
The size of a cell is limited by the relationship of the cell’s outer surface area to its volume
Or surface area to volume ratio
As a cell grows, the volume increase faster than its surface area
Why is this important????
Because the materials that the cell needs (nutrients & oxygen) and waste produced (carbon dioxide) must be able to get in and out of the cell
If a cell grows in volume quicker than the surface area the volume will not be able to leave the cell properly because it has gotten too big

15. PROKARYOTES Lack membrane nucleus and organelles
DNA is located in the nucleoid
Prokaryotes are divided into 2 domains:
Bacteria and Archaea

16. EUKARYOTES Have nucleus and organelles Composed of one or more cells
Eukaryotic cells are larger than prokaryotic cells

17. BASIC PARTS OF A CELL ALL Cells must have Cytoplasm
Genetic information (DNA)
Cell (Plasma) Membrane
Ribosomes

18. Week 7- Friday 10/3 J- Types of Cells sorting activity TI- none

19. ORGANELLES
Sub-cellular structures
“Mini Organs”

20. CYTOPLASM Location/ type of cell: within the cell membrane
Prokaryotes, eukaryotes, & bacteria
Description: jelly-like goo that holds all organelles
Function: contains the fluid of the cell, cytoskeleton, and all other organelles except the nucleus

21. Nucleus Types of Cells: Plants and Animals
Description: Membrane bound structure
Function:
control center of the cell
Carries coded genetic information, DNA, for regulating function and reproducing themselves

22. NUCLEUS Nuclear envelope Nuclear pores
Description: contains the nucleus in a double membrane layer
Function: Regulates what enters/leaves cell
Nuclear pores
Description: tiny protein lined holes cover the surface
Function: allow the passage of RNA and materials to leave the nucleus

23. Nucleolus Nucleolus Type of cell: Inside the nucleus/ eukaryotes
Descriptions: is the site where DNA is concentrated when making ribosomal RNA
Function: makes ribosomes

24. MITOCHONDRIA The “Power House” of the cell
Organelles transfer energy from organic molecules to ATP (Adenosine Triphosphate)
ATP powers all the cell’s chemical reactions

25. Ribosomes Type of Cells: Prokaryote & Eukayotes Description:
small round organelle
Located in the cytosol and on the rough ER
Function: make proteins

26. PLASMA MEMBRANE Type of Cell- Prokaryote & Eukaryote Description:
The cell’s outer boundary
made up of 2 phospholipid layers (bilayer)
Have a hydrophilic (water loving) and hydrophobic (water fearing) layer
Function:
Covers a cell’s surface
Acts as a barrier between the inside and outside of a cell (semipermeable)
All material enters and exits through the plasma membrane
