Title: Characteristics of Living Things


1
Characteristics of Living Things
2
What is Biology?
  • Biology ? the study of living things
  • Bio Life
  • ology study of
  • Living things are classified into 5 groups
  • Animals
  • Plants
  • Fungi
  • Protists
  • Bacteria

In Biology, we call these the 5 kingdoms of
living things.
3
Living vs. Nonliving
  • Living things
  • Biotic
  • Called organisms
  • Made up of CELLS
  • (unicellular and multicellular)
  • Examples
  • Plants
  • Animals
  • people
  • Non-living things
  • Abiotic
  • A no not
  • Examples
  • Soil
  • Rocks
  • Water
  • Air

4
Synthesis
  • How organisms build necessary molecules
  • Examples
  • Protein Synthesis making proteins from DNA
  • Photosynthesis plants make food using energy
    from sunlight

5
Transport
  • How organisms get what they need to cells
  • Examples
  • Circulation and absorption
  • Active transport diffusion osmosis facilitated
    diffusion

6
Excretion
  • How organisms get rid of their waste and balance
    their fluids
  • Examples
  • Removing fluids to balance water
  • Removing unused molecules from food

7
Regulation
  • How organisms control body processes
  • Examples
  • Important to homeostasis- to maintain balance
    within the body
  • Short term change based on stimulus (stimulus and
    response)
  • allows living things to adapt to changes

Sweating reduces body temperature
8
Nutrients
  • How organisms break down and absorb food
  • Examples
  • Fungi decompose dead remains (decomposer)
  • Plants make their own food (autotroph)
  • Animals consume other organisms and absorb food
    (heterotroph)

9
Grow Develop
  • How organisms make new cells and develop
    necessary body parts
  • Examples
  • Birds develop in an egg
  • Mammals develop in a uterus
  • Fungi develop from a spore
  • Plants develop from a seed

Grow to get larger in size body size
Develop to change due to hormonal or mental cues
10
  • Living things are complex and made up of many
    levels
  • 5. Organism
  • 4. Organ System
  • 3. Organs
  • 2. Tissues
  • Cells basic unit of life
  • Atoms, Molecules
  • Elements

11
Muscle cell
Muscle tissue
Heart
Circulatory System/ Organsim
12
Reproduction
  • How organisms make new individuals like
    themselves
  • Examples
  • Prevents Extinction
  • Sexual vs. Asexual
  • Internal or external fertilization

13
Respiration
  • How organisms get oxygen and release carbon
    dioxide to make usable energy
  • A series of chemical reactions that result in the
    release of energy (ATP)
  • Examples
  • Anaerobic respiration no oxygen
  • Aerobic respiration oxygen
  • Plants exchange gasses
