Three categories of protists
|
* animal-like * plant-like * fungus-like |
|
|
How can we tell which category a particular protist belongs to?
|
Depending on how they eat/obtain their food/energy
|
|
|
How do autotrophs make energy?
|
Makes own food through photosynthesis
|
|
|
How do heterotrophs make energy?
|
Eats other organisms to obtain energy
|
|
|
How do decomposers make energy?
|
Breaks down dead and decaying matter and absorbs nutrients
|
|
|
What characteristics do we use to separate animal-like protists into different groups?
|
* how they move/gather food * do they have flagella, cilia or pseudopodia |
|
|
What is a characteristic that is similar to both fungi and protists?
|
Eukaryotic cells
|
|
|
What are decomposers?
|
Organisms that break down dead or decaying matter to release nutrients. Will then absorb these nutrients.
|
|
|
What is the difference between saprophytes, symbiotes, parasites?
|
* Sparophytes are true decomposers – feed on dead tissue; * symbiotes have mutually beneficial relationship between a fungus and other organism; * parasite feeds on living tissue of a host – causes harm |
|
|
How do the hyphae help fungi to break down food and eat?
|
* hyphae release enzymes that help break down dead and decaying matter; * hyphae will then absorb the nutrients released from broken down matter to use as food/energy |
|
|
What is a fruiting body and what is its purpose in respect to fungi?
|
* part we see above ground, * made up of hyphae, * only makes up small part of fungi, * produces spores -> reproductive part of fungi |
|
|
Describe a symbiotic relationship that fungi is involved in.
|
Mycorrhizae – fungi grows on plant roots, fungi increases plant nutrient and water absorption, plant makes food for fungi. Liches – fungi and algae grow together, fungi provides structure and breaks down material, algae provides food for fungi
|
|
|
What are some benefits of fungi?
|
* decompose dead plant/animal, * we can eat mushrooms, * help make bread, beer, wine, * help develop penicillin and vaccines, * have symbiotic relationships |
|
|
What are ways fungi are harmful?
|
* attack grains/fruit, * some people have mold allergies, * can cause fungal infections in humans, * can produce toxins by poisonous mushrooms |
