The organization of life
MONOMERS
•Atom/Element
•What are the six basic
atoms found in EVERY
form of life?
•Molecule
•Two or more
atoms/elements combine
to make a molecule.
CHNOPS
•A chain of two or more
molecules.
•Proteins
•Carbohydrates
•Lipids
•Nucleic Acids
CELL
•Basic unit of life.
•Two types:
•Prokaryotic
•Eukaryotic
POLYMERS
AKA
MACROMOLECULES
What processes do cells undergo to create energy?
Cell Theory
• All new cells arise from existing cells
(mitosis/meiosis)
• ALL living things are made of cells
• Cells are the basic unit of structure and function of
organisms
• 2 types of cells : Prokaryotes and Eukaryotes
Common Cell Features
features that are common to ALL cells:
•
•
•
•
Cytoplasm
Cell membrane
Cytoskeleton
Ribosomes

Photosynthesis &
Cellular Respiration
• Photosynthesis converts light energy into organic
compounds that store energy (glucose). (Autotrophs 
Plants, Protists, Bacteria)
Chloroplast of
a plant cell
• Cellular respiration is the process that cells use to
obtain the energy from organic compounds and convert it
into ATP. (Eukaryotic cells)
3 STAGES:
1. Energy is captured from sunlight
2. Energy is stored as ATP, and NADPH
3. Organic compounds (glucose) are made using
the ATP, NADPH, and CO2
The first two stages of photosynthesis are LIGHT
DEPENDENT and occur in the thylakoid (in chloroplast).
The third stage is not light dependent and occurs in the
stroma.
