Study Notes
Developmental Forms
- Hexapods experience life stages of egg, larvae, pupa/cocoon or chrysalis, and adult forms, describing holometabolism, a unique form of development.
Phototaxis in Zooplankton
- Negative phototaxis in zooplankton like Daphnia can be accounted for by the avoidance of predators, finding food, or seeking optimal light conditions.
Chelicerata Characteristics
- All members of Chelicerata feature book lungs except scorpions, which have book-like organs.
Embryonic Development
- In tripoblastic animals, the coelom forms during embryonic development, when the mesoderm layer will also form.
Arthropoda Characteristics
- Tagmata, chitin, antenna, tracheae, and Malpighian tubules are terms collectively associated with the subphylum Hexapoda.
Reproductive Modes
- Daphnia are able to make offspring without gametes and genetic recombination, a form of reproduction referred to as parthenogenesis.
Arthropod Body Regions
- Body regions in arthropods are known as tagmata.
Mollusk Characteristics
- Mollusks in general demonstrate a unique structure called the radula or a modified radula that is beak-like, but class Monoplacophora does not have a radula for feeding and uses an entirely different set of feeding structures.
Plant Evolution
- The fossil Cooksonia is associated with the first bryophyte plants.
- Leaves evolved first based on fossil evidence.
Seed Plant Characteristics
- The products of the microsporangia in seed plants are associated with pollen.
Land Plants
- Land plants are also called embryophytes, named after their protective and supportive features present in the early diploid life stage.
Fern Characteristics
- Ferns are vascular plants and have true roots, stems, and leaves.
Protist Characteristics
- Foraminifera, a type of protist, occasionally resemble tiny snails, and over time, massive sedimentary accumulations of this protist create limestone.
Pterophytes
- The sporangium is the container that produces spores in Pterophytes.
Moss Characteristics
- Antheridia are the male gametangia in moss.
Cell Types
- Anisogamous cells are those where the sex cells called gametes are of different sizes.
Zoonotic Prokaryotes
- Francisella tularensis is a zoonotic prokaryote.
Prokaryote Characteristics
- Cyanobacteria are thought to have altered the Earth's atmosphere by first producing oxygen billions of years ago.
Land Plant Evolution
- Land plants share a common ancestor with the supergroup Charophyta.
Gametophyte Structure
- Conifers and grass (a flowering plant) send their gametes through the air using the gametophyte structure called pollen.
Extremophile Prokaryotes
- Psychrophilic prokaryotes are tolerant of cold conditions, such as the icy waters of Antarctica.
Photosynthetic Protists
- Coccolithophores, a type of photosynthetic protist, may play a significant role in regulating the composition of the atmosphere via the "biological carbon pump" as it takes up carbon dioxide that ultimately can wind up in sediments in the deep ocean.
Endospore Formation
- Some bacteria, such as Bacillus, can form endospores.
