✔Every 5 years
Who uses the data from the U.S. Census of Agriculture? - correct answer ✔It
is used by all those who serve farmers and rural communities -- federal, state
and local governments, agribusinesses, trade associations and others (i.e.
community planners and local governments design needed programs and
services)
What are two characteristics that the Census of Agriculture records about U.S.
farms and farmers? - correct answer ✔Two characteristics could be
commodities, acreages, market values and farmer and rancher income and
expenditures (as well as gender, sex, etc. of the farmer)
Which state of the U.S. ranks highest in terms of the total dollar value of its
agricultural production? - correct answer ✔California
What are two crops that are commercially produced in California and
contribute to 99% or more of the total U.S. production of that crop? - correct
answer ✔Almonds, artichokes, dates, figs, grapes (raisin), kiwifruit, olives,
peaches, pistachios, plums, pomegranates, rice, walnuts

commodities grown in the county? - correct answer ✔Tomatoes
(processing), grapes (wine), almonds, rice, walnuts
,How is the world's human population size expected to change over the next
several decades? - correct answer ✔Increase
Prokaryotes - correct answer ✔Organisms that are unicellular (one-celled)
and do not have a nucleus or other membrane-enclosed organelles (bacteria
and archaea)
Eukaryotes - correct answer ✔Organisms whose cells have a nucleus and
contain their genetic material (DNA) inside the nucleus (consists of all plants,
algae, animals, fungi, and many microscopic organisms)
Which of the following are capable of photosynthesis: fungi, algae, animals,
true plants? - correct answer ✔Algae
Algae - correct answer ✔-Large, diverse groups that are not necessarily
closely related
-Consists of green algae, red algae, brown algae, and others
-Each is characterized by their pigments and other features.
True plants - correct answer ✔-Evolved from one group of green algae
-Evolved characteristics that allowed them to live on land rather than in water
Bryophytes - correct answer ✔-Mosses, liverworts, hornworts
-Plants with no vascular tissue
-Plants with no seeds
Which of the following plants groups have vascular tissues: algae, ferns,
conifers, angiosperms? - correct answer ✔Ferns and angiosperms
,Vascular plants - correct answer ✔Plants with vascular tissues that conduct
water and nutrients from one part of a plant to another
What are the two types of vascular plants? - correct answer ✔Ferns and
fern-allies and seed plants
Ferns and fern-allies - correct answer ✔Have vascular tissue but do not
make seeds during sexual reproduction
Seed plants - correct answer ✔Vascular plants that produce seeds during
sexual reproduction (i.e. cycads, conifers, angiosperms)
What are vascular tissues? What function do they serve in plants? - correct
answer ✔
Which of the following groups of plants provide almost all of our food, spices,
medicines, biofuels, and ornamental plants: cycads, conifers, angiosperms? -
correct answer ✔Angiosperms
What are the two major groups of flowering plants (angiosperms)? How do the
two groups differ? - correct answer ✔-The two major groups of flowering
plants are monocots and eudicots
-Monocots have one embryonic cotyledon ("seed leaf") and eudicots have two
embryonic cotyledons ("seed leaves")
Monocots - correct answer ✔Plants have long, narrow "true" leaves with
parallel veins (i.e. grasses [corn, wheat, barley, oats, rye])
, Eudicots - correct answer ✔Plants have broad "true" leaves with net-like
pinnate or palmate veins (i.e. tomato, soybean, canola, strawberry, grape,
almond)
What is a cotyledon? - correct answer ✔-A cotyledon is a "seed leaf"
-Primary embryonic leaf within the seed
-Provides nutrients for the new plant
What kind of root system do monocots and eudicots have? - correct answer
✔Monocots have a fibrous root system composed of many thin roots that are
nearly equal in diameter and eudicots have a taproot system with a primary
taproot, which extends downward by tip growth, and smaller lateral roots
What are the functions of the shoot system of plants? What are functions of
the root system? - correct answer ✔-The shoot system consists of stems and
leaves and is responsible for photosynthesis and reproduction
-The root system consists of roots and root hairs and anchors a plant in soil,
take up water and minerals and store starch
Plant meristem - correct answer ✔Specialized tissues in plants that can
continuously give rise to new cells and organs
Meristems give rise to what three plant tissue systems with specialized
functions? - correct answer ✔Dermal, vascular and ground tissue
Dermal tissue - correct answer ✔Protects plants; outer covering in contact
with environment
Vascular tissue - correct answer ✔Conducts water, solutes, and some
hormones; provides mechanical support
