Study Notes
Green Algae
- Resembles sea lettuce with beautiful blades and connectors
- Has plumacious structures, similar to a feather
- Often mistaken for ferns due to similar appearance
- Photosynthesizes, obtaining nutrients from surrounding water
- Rhizomatous connectors are important characteristic
Human Behavior
- Many people spend excessive time on phones and computers instead of outdoors
- This behavior is dangerous and contributes to societal problems
- Encourages people to get outdoors
Fungi
- Key players in the biosphere for breaking down organic matter
- Can be harmful, causing diseases in plants and animals
- Important for forest ecosystems; decomposing organic matter, providing nutrients and contributing to overall ecosystem health
- Important for human society with roles in food production and medicine
- Fungi have a remarkable ability to decompose cellulose and Lignin.
- Some are parasites or mutualists.
- Cell walls of fungi are made of chitin.
Slime Molds
- Two types: plasmodial (single mass) and cellular (separate cells)
- Classified differently from fungi; despite shared characteristics, they're categorized in separate groups
- Play crucial roles in decomposing materials and cycling nutrients in ecosystems
Reproduction in Fungi
- Fungi have two primary reproductive methods:
- Asexual (sporangia, budding) and sexual (plasmogamy, karyogamy)
- Some fungi exhibit remarkable survival strategies, remaining dormant in adverse conditions and quickly reproducing once favorable conditions return
- Many diverse reproductive strategies in Fungi.
Food Sources
- Certain types of fungi and proteins are important sources of food
- People benefit from utilizing these sources correctly
- Mushrooms – a common food source
- Yeast – involved in bread and other food products
- Fungi play a crucial role in decomposition and nutrient cycling in various ecosystems.
