• Cell
• Tissue
• Organ
• System
• Organism
• Population

CELL
Parts of Cell
1. Nucleus - control center
• nucleolus - ribosomes
• nuclear pore - pathway
• nucleoplasm
2. Cytoplasm
• organelles - solid part
✓ mitochondria - power house of the cell, produces ATP
✓ plastid - container
➢ leucoplast - colorless, carries fats and oils
➢ chromoplast - all colors except green
chloroplast - green
✓ endoplasmic reticulum
➢ smooth ER - lipids (without ribosome)
➢ rough ER - proteins (with ribosome)
• cytosol - jelly-like structure
3. Cell Membrane/Plasmalemma
• phospholipid bilayer
✓ hydrophilic - phosphate head (carbohydrates)
✓ hydrophobic - fatty acids (lipids)
➢
REPRODUCTION
• Sexual Production
• Asexual Production
✓ Budding
✓ Regeneration
✓ Fragmentation
✓ Vegetative
✓ Binary Fission
fertilization, diversity
genetically identical
outgrowth (yeast, hydra)
(starfish, lizards)
(planaria)
plants (marcotting, grafting)
(bacteria)
CELLULAR RESPIRATION
• Glycolysis
occurs in cytoplasm, produces pyruvic acid (2 ATP)
• Kreb Cycle (Citric Acid Cycle)
occurs in matrix of mitochondria, produces CO2 (2 ATP)
• Electronic Transport Chain
chemiosmosis, produces 34 ATP
METABOLISM
• Catabolic
break down → energy released → loss of dry mass
Cellular Respiration
• Anabolic
build-up → energy stored → gain of dry mass
Photosynthesis
Producer
Consumer
Decomposers
autotroph
heterotroph
chemical recyclers
ECOLOGICAL RELATIONSHIP
• Mutualism
both organism benefit
•
one benefits | one no harm, benefit, or no effect
Commensalism
• Parasitism
one benefits | one harm
• Competition
✓
✓
both organisms are harmed
Intraspecific (self)
same species
Interspecific (other)
different species
• Predation
one benefits | one harm (act of killing)
• Grazing
one benefits | one harm (no killing)
Mosquitoes
Mollusk
aedes egypti (dengue)
anopheles (malaria)
mussels, scallops, oysters
Dinoflagellates
red-orange protists, causes red tide
Greenhouse Gas
natural thermal blanket
✓
Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (N20)
SOLAR SYSTEM
•
Heliocentric Model
✓ the sun is the center
✓ Nicolaus Copernicus
•
Geocentric Model
✓ the earth is the center
✓ Ptolemy
