Plant structure
Organ that anchors a plant and uptakes water/nutrients.
What is a root?
Function of stomata
Hint: not asking about transpiration...yet
What is gas exchange?
i.e. takes in carbon dioxide; releases oxygen and water
Type of allele that will be expressed if present
What is domant?
True or False? Substinance farming is characterized by huge monocultures, heavy use of chemical fertilizers/pesticides, significantly erodes top soil.
What is FALSE?
Hormone that controls phototropism
What is auxin?
Location of growth on a plant, be it primary or secondary
What is a meristem?
Function of a "tuber," a type of modified stem
What is energy storage and/or asexual reproduction?
What is homozygous?
Describes a food system where people do not cultivate or store food but rather forage as they need it
What is hunter-gatherer?
Organism that contains recombinant DNA (rDNA) or DNA from 2 or more organisms

What is corn?
Mesophyll and parenchyma tissues are an example of this type of tissue
What is ground tissue?
Phloem is a type of ______ tissue
What is vascular?
Process by which water is released through the stomata and allows water to move into and up through the plant
What is transpiration?
Dominance pattern in which a heterozygote will produce an intermediate phenotype between the two homozygous parents
What is incomplete dominance?
Practice in which the same crop is not grown in the same location year after year
What is crop rotation?
True or False? The spine of a cactus is a modified leaf.
What is TRUE?
Type of bud that will only grow if the apical meristem is removed
What is the axillary bud?
True or False?
The type of growth produced by a lateral meristem (also called the vascular cambium) is called primary growth and allows the plant to grow taller.
What is FALSE?
In certain plants, purple flowers (R) are dominant to white flowers (r). A heterozygous (Rr) plant is crossed with a homozygous dominant (RR) plant. The probability that the offspring will be white-flowered is...
