Characteristics of living things

1
Characteristics of living things

• In order to be alive ALL cells MUST meet all the
  characteristics of living things
• The Cell (Discovery channel)

Amoeba
2
Cell Organization

• Organelles Little Organs
• Eukaryotic cells have organelles that perform
  all of the necessary life functions!
• Some cells have more or different organelles.
• The cell

3
Cell Wall

• Non-living, outside of plant cells
• Protects Supports
• Water oxygen and carbon dioxide can pass through
  the membrane

4
Cell Membrane

• Surrounds animal cells inside cell wall of
  plants
• Gatekeeper controls what goes in and out of the
  cell

5
Nucleus Cell Manager

• 1. Directs all activities
• 2. Contains DNA
• RNA
• 3. Manager
• 4. Transmits hereditary
• information
• 5. Control center

6
Nuclear Membrane

• Membrane that surrounds nucleus
• Permits materials in and out of Nucleus

7
Nucleoplasm

• Internal fluid of the nucleus

8
Nucleolus

• Inside the nucleus
• Makes Ribosomes contains RNA
• Protein Synthesis Plays a role in the making of
  proteins

9
Chromatin

• Thin threads made up of DNA RNA
• Form chromosomes

10
Cytoplasm

• Cytoskeleton surrounds and suspends the
  organelles.
• Always moving (fluid)

11
Endoplasmic Reticulum

• Rough Endoplasmic Reticulum (Rough ER) contain
  attached ribosomes on the surface.
• Smooth ER contain enzymes for cell
  metabolism

12
Ribosomes

• Round organelle either attached to the Rough ER
  or floating in the cytoplasm
• Site of Protein Production

13
Mitochondria

• Makes Energy The POWERHOUSE of the Cell

14
Vacuoles

• Round Organelle
• Store food enzymes Waste
• Store water in plants

15
Golgi Apparatus

• Closely stacked sacs
• Package proteins
• UPS of the Cell

16
Chloroplasts

• found in plants
• Make store food
• Contain chlorophyll that gives plants color and
  absorbs sunlight!

17
Comparing plant animal cells

• Characteristic Animal Cell
  Plant Cell
• General Shape round 
   rectangular 
• Position of Nucleus   Cell's center 
  off-center
• Outer Layer  cell membrane 
  cell wall 
• Vacuoles many scattered
  One with water
