100
What is one function of the roots?
To anchor the plant or absorb food from the soil
100
Which gas is one of the starting ingredients for photosynthesis?
Carbon dioxide
100
Why does a plant need air and water ?
The air supplies carbon dioxide and water is also a starting ingredient of photosynthesis
100
What does haploid mean?
Containing half the normal amount of genetic material
100
Name the process in which there is only one round of cell division
Mitosis
200
What is the function of the leaves?
To make food for the plant through photosynthesis
200
Which very abundant compound is also a starting ingredient for photosynthesis?
Water
200
What is unique about the growing conditions for conifers?
photosynthesis can occur year-round
200
What is the main difference between the sporophyte and gametophyte generation?
The gametophyte has half the amount of genetic material as the sporophyte.
200
What is the advantage of meiosis over mitosis?
Meiosis produces more genetically diverse cells
300
What is the function of the ovary?
To store egg cells or oocytes
300
What is the simple sugar produced in photosynthesis?
Glucose (C6H12O6)
300
What is special about the growing conditions for epiphytes?
Epiphytes rely on a host for nutrition (i.e. moss growing on a branch)
300
Is the sporophyte smaller or larger than the gametophyte for mosses?
The sporophyte is smaller than the gametophyte
300
Why is it possible for the two daughter cells to have the same amount of genetic material as the single parent cell in mitosis?
The amount of genetic material doubles and the cell size doubles before the split
400
What is the function of the sepal?
To support the flower
400
What gas is produced in photosynthesis?
Oxygen (O2)
400
Why are evergreens more likely to be found in a temperate rain forest?
The low temperatures are not as extreme which allows the chorophyll to maintain the state needed to support photosynthesis
400
Who pollinates the flowers?
Mainly birds and insects
400
Why do leaves appear green?
Because the chlorophyll in the leaves absorb mainly red light and reflect green light
500
What parts are characteristic of vascular plants?
xylem and phloem
500
Why could growing more plants reduce global warming?
These plants could undergo photosynthesis which consumes carbon dioxide which is a greenhouse gas.
500
Why do bryophytes often rely on a host for nutrition in a temperate rain forest?
The very tall conifers filter out sunlight, making photosynthesis more challenging for the moss.
500
What does the sporophyte generation have in common (in terms of growing conditions) for the moss and the fern?
In both cases, the sporophyte grows on top of the female gametophyte
500
How does the spores develop into a gametophyte during the life cycle of a fern?
The spores undergo mitosis
