Study Notes
Domains of Life
- Prokaryotes and Eukaryotes: How domains of life are distinguished.
Cell Structure
- Prokaryotic Cell: Lacks a nucleus and other membrane-bound organelles.
- Eukaryotic Cell: Contains a nucleus and other membrane-bound organelles.
- Archaea: A type of prokaryote found in extreme environments like soil, wetlands, lakes, oceans, and ice.
Prokaryotes
- Prokaryotic Cell Type: Bacteria are prokaryotic cells.
- Microbiota: The community of microorganisms living in and on the human body.
- Sickness: Endotoxins from certain microorganisms can cause sickness in humans.
Eukaryotes
- Eukarya Domain: Protists are in the domain Eukarya.
- Eukaryotic Cell Type: Protists are eukaryotic cells.
- Autotroph/Heterotroph: Two main groups of protists.
Plants
- Major Plant Groups: Bryophytes, ferns, gymnosperms, angiosperms are four main plant groups.
- Vascular System: Lycophytes, ferns, gymnosperms, and angiosperms have lignin and a vascular system.
- Ferns: Seedless vascular plants.
- Gymnosperms: Group of seed plants with seeds directly on scales of cones.
