Study Notes

Plant Kingdom

Two main groups of plants: gymnosperms and angiosperms.
Gymnosperms have "naked seeds" borne on cones, not enclosed in an ovary.
Angiosperms (anthophytes) produce flowers for reproduction.
Angiosperms are divided into monocots (one seed leaf) and dicots (two seed leaves).
Plants are further classified into vascular and nonvascular plants.
- Nonvascular plants (bryophytes): lack vascular tissues for transporting materials; thallus body; anchored by rhizoids; thrive in moist environments.
- Vascular plants: possess xylem and phloem for transport; more complex body structure. Subdivided into spore-forming and seed-forming plants.
  - Spore-forming plants: include ferns, lycopods, psilotum, and equisetum; drought-resistant spores; anchored by rhizomes or prostrate structures; strobili (cone-like) spore-bearing structures.
  - Seed-forming plants: gymnosperms and angiosperms; possess woody tissue, complex vascular systems, and seeds enclosing embryos.

Fungi Kingdom

Mostly multicellular, eukaryotic, and immobile.
Cell walls composed of chitin.
Heterotrophic (parasitic or saprophytic).
Diverse roles: symbiotic (decomposers), beneficial (e.g., antibiotics), and edible (e.g., mushrooms).
Asexual reproduction via spore formation and budding.
Differ from plants by lacking chlorophyll and having chitinous cell walls.
Absorbent organisms.
Reproduce through sexual and asexual spores.

Protists Kingdom

Simplest eukaryotes.
Three main groups: plant-like, animal-like, and fungus-like.
Fungus-like protists share characteristics of fungi and protozoa; include cellular and plasmodial slime molds; saprotrophs found in decaying organic matter.

Animalia Kingdom

Multicellular eukaryotes.
Mostly actively mobile and heterotrophic.
Distinguishing characteristic: symmetry (bilateral: body divisible into two mirror-image halves).

Animal Groups: Detailed Characteristics

Birds: Anatomy adapted for flight; unique digestive system for eating on the fly and digesting later; evolved alongside dinosaurs during the Jurassic period (160 million years ago); Archaeopteryx is a well-known fossil. Warm-blooded vertebrates.
Mammals: Highly adaptable; diverse locomotion (terrestrial, aquatic, even flying); four defining traits: hair, mammary glands, hinged jaw, three middle ear bones; most have specialized teeth and external ears. Warm-blooded vertebrates.
Fish: Live in water; possess a backbone; developed special senses; highly diverse and evolutionarily old. Cold-blooded vertebrates.
Reptiles: Air-breathing vertebrates; scaly or bony skin; regularly shed skin; metabolism and reproduction dependent on environmental temperature. Cold-blooded vertebrates.
Amphibians: Small vertebrates requiring water or moist environments for survival. Cold-blooded vertebrates.
