Biodiversity Flashcards
Prokaryotes
Cells with no membrane bound organelles, no nucleus, and simple in structure.
Eukaryotes
Cells with organelles, nucleus, and can be both multicellular or single cellular.
Pilus
Hair like projections for latching
Capsule
Contains cell membrane
DNA
Genetic material
Cell wall
Rigid exterior for protection
Flagellum
Whip-like tail for movement
Describe archaea protection
Cell membrane contains lipids (fats) that can not be broken down. Also known as phospholipid monolayer. Cell walls are also rigid.
Where can archaea survive
Extremely high and low temperatures, low light conditions, low O2 levels, high Na levels and low pH.
Nutrients of archaea
Remove hydrogen, decay matter, and decompose. Also responsible for removing and adding nitrogen and oxidize sulfur.
Importance of archaea
Sewage treatment, produce enzymes, and produce foods all in harsh conditions.
Characteristics of archaea
Prokaryotes, single cellular, contain cell wall and membrane
5 Main characteristics of life
Movement, sensitivity, development, complexity, death
5 Fundamental characteristics of life
Cellular organization, metabolism, reproduction, hereditary information, homeostasis
Cilia
Hair like projections for movement
Pseudo
Finger like projections dragging protists forward
Characteristics of protists
Eukaryotic, single cellular
Anatomy of protists
Cell membrane, nucleus, chloroplasts, flagellum, eye spot, vacuole
Binary fission
Parent cell splits into 2 daughter cells
Multiple fission
Nucleus of parent cell divides multiple times before dividing into multiple offspring
