BIOL 102 EXAM 2
Which of the following is not an example of a group of angiosperms? (cacti, cherry trees, pine trees,
grasses, orchids)
- Pine Trees
Which of the following statements about ferns is incorrect? (Their sporophyte is dominant, They require
liquid water for fertilization, Their seeds are dispersed via the wind, They have vascular tissue for
distributing water and nutrients throughout the plant, Their spores are contained in sporangia.)
- Their seeds are dispersed via the wind
Anthers and stigmas can be found on:
- angiosperms.
Which of the following is a significant new challenge that plants faced when they moved from their
aquatic environment onto the land? (light availability, desiccation, nutrient availability, predation, the
need for osmotic regulation)
- Desiccation
Which of the following is characteristic of gymnosperms? (They are more diverse than the angiosperms,
They are wind-pollinated, The gametophyte generation is dominant, They are water-pollinated.)
- They are wind-pollinated
Dispersal of fungal spores is typically done by:
- wind
Angiosperms and gymnosperms differ from each other in that:
- angiosperms tend to rely on animal pollinators, whereas gymnosperms tend to rely on wind
pollination.
In most cases, the relationship between roots and fungi in mycorrhizae can best be described as:
- symbiosis
,You are taking a hike down a forest trail and see the familiar sight of a mushroom on the ground. This
visible portion of a fungal body is the structure also referred to as the:
- fruiting body
Which of the following comparisons and contrasts between fungi and plants is incorrect? (Fungi cannot
photosynthesize, but plants can, Both fungi and plants use chitin as a structural stabilizer, Fungi are
heterotrophs, but plants are not, Both fungi and plants have cell walls, Both fungi and plants undergo
sexual reproduction)
- Both fungi and plants use chitin as a structural stabilizer.
What is the source of oxygen released by plants during photosynthesis?
- Photolysis of water
The process of splitting water to release oxygen, hydrogen and electrons occurs during the _________
- light dependent reactions
The carbon incorporated into the carbohydrates comes from _____________.
- carbon dioxide
During hot and dry weather conditions _______ plants are more efficient at carrying out photosynthesis.
- C4
The organic molecule produced directly by photosynthesis is ______.
- Sugar
If a thylakoid membrane was punctured so that its interior was no longer separated from the stroma,
which of the following processes would be directly affected? (the passing of electrons to NADP, the
absorption of energy by chlorophyll, the synthesis of ATP, the splitting of water)
- Synthesis of ATP
PS 1 and PS II and the electron transport chain are located in the _________.
thylakoid membrane
, C4 plants are so called because during photosynthesis these plants _________.
- produce a four carbon compound (Oxaloacetic Acid- OAA) as the first stable compound
The dark reactions (Calvin cycle) require all of these chemicals, except ...... (ATP, NADPH, carbon dioxide,
oxygen, RuBP)
- Oxygen
What products from the light reactions move on to the Calvin cycle?
- ATP and NADPH
A photosystem is _________.
- a collection of pigments arranged in the thylakoid membrane
During the light reactions of photosynthesis, ATP is produced when hydrogen ions move __________.
- down a concentration gradient from the thykaloid space to the stroma
When electrons from PSII are passed on to the electron acceptor, they are replaced by electrons that
come from ___________.
- water
The final acceptor of electrons during the light reactions is .....
- NADP+
What are the four groups of fungi, and how are they classified?
Chytrids (Chytridomycota)
Bread Molds (Zygomycota)
Club Fungi (Basidiomycota)
Sac Fungi (yeasts) (Ascomycota)
Classified by spore-producing structure
How do fungi eat? Are they heterotrophs or autotrophs?
