bio test fungi Flashcards
(9 cards)
1
Q
- What are the characteristics of Fungi? (6)
A
- Heterotrophic
- Most are multicellular
- Most are aerobic
- Cell wall made of chitin
- Eukaryotic
- Extracellular Digestion: break down food outside of their body by secreting enzymes to break down large molecules into smaller ones that can be absorbed
2
Q
- What makes up the structure of fungus?
A
- Fruiting body: reproductive organ, produces spores, usually above ground
- Mycelium: the “roots” of a fungus, absorbs nutrients, usually below ground
- Hyphae: thin threads that make up the bodies of multicellular fungi (contains cytoplasm, cell wall and septum)
3
Q
- Name and picture in your head all of the parts that make up the fungal cell. (15)
A
- Ribosome
- Lysosome
- Vesicle
- Smooth ER
- Rough ER
- Nucleus
- Nucleolus
- Vacuole
- Peroxisome
- Golgi Apparatus
- Septum
- Mitochondrion
- Cytoplasm
- Cell Wall
- Cell Membrane
4
Q
- What are the four classifications of mushrooms?
A
- Moulds: Many short hyphae and fruiting bodies
- Mushrooms: large fruiting bodies attached grown on sticks
- Sac fungi: Many types of fruiting body, classified by spherical spores
- Yeast: Spherical and Unicellular
5
Q
- What are the nutritional modes of Fungi? (4.5)
A
- Absorption from decaying matter
- Parasitic relationship; syphon nutrients from living cells
- Specialized structures to catch pray
- Mutualism with other organisms (0.5), Mycorrhiza: connections between fungal hyphae and plant roots to allow organisms to share nutrients.
6
Q
- True or False: fungi can only reproduce asexually?
A
False you fucking shit head
7
Q
- TELL ME A LIL’ BIT ABOUT SPORES (3)
A
- Can result in asexual/sexual reproduction
- Survive in extreme conditions; germinate when the time is right
- spores rely on the environment to move
8
Q
- How does Binary Fission work in fungi?
A
- Grow from buds that turn into identical cells
- cell separation happens, leaving bud scar on daughter cell, and birth scar on parent.
9
Q
- Name the positive and negative fungi interactions:
A
Positive:
- Decomposers
- Mutualistic
- Food Production
- Medicine
Negative:
- Parasitic (e.g. ringworm, thrush)
