In a moss, the dominant generation is that we see is the _, while in a gymnosperm the most dominant stage is the_.
The classification of plants, in order that evolution is thought to have occured, is
bryophyte, seedless vascular, gymnosperm, angiosperm
Which of the following statements regarding ferns is true?
Ferns are classified as seedless vascular plants.
All plants carry out the life cycle of alternation of generations. The haploid version of the plant is called _, while the diploid version is called _.
Which of the following characteristics tends to limit bryophytes and seedless vascular plants to habitats that are relatively moist?
dependence on the presence of water for reproduction.
The increase in girth associated with production of wood and bark in trees occurs as a consequence of
In plants, the vascular tissue that consists of living cells that distribute sugars throughout the plant is called
In plants, the vascular tissue made of dead cells that transport water and minerals from the roots is called
The _, a zone of rapid cell divisions that produces growth, is found at primary root and stem tips.
The increase in height associated with the formation of a seedling occurs as a consequence of
Plants make glucose and other carbohydrates because it is more stable (can hold more energy) than ATP or NADPH.
Carotene is another plant pigment that absorbs light in the orange portion of the visible spectrum.
Grana in chlorplasts could be described as a stack of sacks while thylakoids are one of those sacks that makes up the stacks.
How do the reaction centers of photosystem I and II differ?
Each preferentially absorbs slightly different wave lengths of light
The electrons lost from the reaction center of photosystem I are replaced by electrons from
Which of the following photosynthetic pigments can be found at the photosystem reaction center?
What is the mechanism to reduce the effects of photorespiration in C4 plants?
They separate carbon fixation and sugar production physically.
The addition of oxygen to RuBP by rubisco to form a two-carbon product that is then broken down by the cell to carbon dioxide and water defines
What is the main adaptive advantage of the C4 and CAM photsynthesis strategies over the C3 strategy?
They help the plant conserve water and synthesize glucose efficiently under hot, dry conditions.
is an evolutionary relic from when atmospheric O2 levels were low and did not interfere with rubisco.
What is the mechanism used to reduce the effects of photorespiration in CAM plants?
They separate carbon fixation and sugar production by time.
