Objective

• Define cell, tissue and relate the structure of
  the following to their functions

3
Key Vocab

• Tissue
• Ciliated Cell
• Root Hair Cell
• Xylem Vessels
• Muscle Cells
• Red Blood Cells
• Organs
• Organ Systems

4
Cell

• Basic unit of structure and function of all
  living things
• Cell Theory
• All living things are made up of cells
• Cells are the basic unit of structure and
  function in living things
• All cells come from pre-existing cells

5
Tissue

• tissue is made up of a group of cells with
  similar structures, working together to perform a
  shared function
• Different tissues
• contain specialized
• cells to perform specific
• functions of that
• tissue

6
Ciliated Cells

• Commonly found in the respiratory tract
• Contain cilia, microscopic hair like projections
  on the surface of the cell that sweep fluids or
  particles away
• Function movement

7
Ciliated Cells
8
Root Hair Cell

• cells found near to the tip of the roots of
  plants.
• Most water enters the root through them.
• The thin hair-like extension of
• each cell gives a large surface
• for water to enter across.
• Function absorption

Root Hair Cell
10
Xylem Vessel

• xylem is a type of vascular tissue found in
  plants
• two major functions
• the conducting of water and
• mineral salt from root to leaves,
• to provide mechanical strength
• (support) to the plant body.
• Function conduction support

11
Xylem Vessel
12
Muscle Cells

• skeletal muscle cells found in muscles attached
  to our skeleton
• voluntarily controlled
• function contraction

13
Muscle Cells
14
Red Blood Cells

• Travel through your blood vessels delivering
  oxygen and removing wastes
• Appear red because they
• contain hemoglobin that binds
• oxygen for transport
• function transport

15
Red Blood Cells
16
Organs

• An organ is a structure made up of a group of
  tissues, working together to perform specific
  functions

17
Organ Systems

• An organ system is a group of organs with related
  functions, working together to perform body
  functions
