Study Notes
Algae
- Eukaryotic organisms that are not plants, but rather a group of simple aquatic organisms
- Can be found in freshwater, saltwater, and terrestrial environments
- Characterized by the presence of chlorophyll, but lack true roots, stems, and leaves
- Examples: green algae, red algae, brown algae, diatoms, and cyanobacteria
Characteristics of Algae
- Autotrophic: produce their own food through photosynthesis
- Simple cellular structure: no tissues or organs
- Reproduce by fragmentation, binary fission, or production of spores
- Can be unicellular or multicellular
Importance of Algae
- Primary producers: form the base of aquatic food webs
- Produce oxygen: contribute to the Earth's oxygen supply
- Nutrient cycling: play a crucial role in the decomposition of organic matter
- Food source: used as a food source for humans and animals
Bryophytes
- Non-vascular plants: lack a vascular system for transporting water and nutrients
- Small, herbaceous plants that grow in damp environments
- Characterized by the presence of rhizoids, which are used for anchorage and nutrient uptake
- Examples: mosses, liverworts, and hornworts
Characteristics of Bryophytes
- Non-vascular: lack xylem and phloem tissues
- Simple leaf structure: leaves are usually one cell layer thick
- Reproduce by producing spores, which are similar to those of ferns and other vascular plants
- Require a moist environment: cannot survive in dry conditions
Importance of Bryophytes
- Ecological importance: play a crucial role in the formation of peat and the cycling of nutrients
- Pioneer species: can colonize and prepare the environment for other plant species
- Erosion control: help to prevent soil erosion and landslides
- Indicator species: can be used to monitor the health of ecosystems
