What do tracheids lack? |
Cytoplasm |
|
|
What essential ecosystem service is provided by land plants? |
Plants perform oxygenic photosynthesis. |
|
|
Describe the stomata |
A stoma (singular) consists of an opening surrounded by specialized guard cells. When the guard cells become taut, they open the pore, allowing the intake of carbon dioxide and the release of oxygen. |
|
|
What adaptation reduced the dependence of seed plants on water for fertilization? |
Pollen |
|
|
Identify the two growth forms of fungi. |
Yeasts and mycelia |
|
|
Which hyphal feature is key to the way a fungal mycelium obtains food? |
Thin filamentous shape |
|
|
True or False: Were the earliest fungi aquatic? |
True. |
|
|
Why do fungi carry out extracellular digestion? |
Only small molecules can diffuse across the plasma membranes of hyphae. Macromolecules must first be broken down. |
|
|
What enzyme do fungi use to digest lignin? |
Lignin peroxidase |
|
|
What is plasmogamy |
It is a stage in the sexual reproduction of fungi, in which the cytoplasm of two parent cells (usually from the mycelia) fuses together without the fusion of nuclei, effectively bringing two haploid nuclei close together in the same cell. |
|
|
Which group of fungi is largely aquatic? |
Chytrids |
|
|
Parasitic fungi |
The major destructive impact that fungi have on people is through food spoilage and through the effects of rusts, smuts, mildews, wilts, and blights on crops. Only a small fraction of fungal species cause illness in humans. |
|
|
Heterotrophs |
can use energy from sunlight (photoautotrophs) or inorganic compounds (lithoautotrophs) to produce organic compounds such as carbohydrates, fats, and proteins from inorganic carbon dioxide. |
|
|
Monotremes |
Mammals that lay eggs(Playtypus) |
