Question 1

Question
Which of the following statements is FALSE regarding plant meristems?
Answer
  • Apical meristems are found in shoot tips, root tips and buds and are responsible for the increase in the length of these plant parts
  • Lateral meristem, sometimes referred to as the cambium, is responsible for the increase in stem and root diameter or thickness
  • All active meristems receive priority for the food material and minerals available within the plant and are often referred to as sinks
  • Meristematic areas encompass a large mass of cells

Question 2

Question
ALL MUST BE TRUE. The primary functions of roots are to: i. take up water and soluble mineral nutrients from the soil ii. produce carbohydrates through photosynthesis iii. store excess food materials iv. anchor the plant
Answer
  • True
  • False

Question 3

Question
Roots require water and food material produced in the shoots, but not oxygen in order to function and grow properly.
Answer
  • True
  • False

Question 4

Question
Plants with separate male and female flowers on the same plant are termed dioecious.
Answer
  • True
  • False

Question 5

Question
Buds are meristematic structures along the stem that are composed of compressed, immature, leafy shoots, flowers or both. They may be dormant for a portion of the year of for many years before they become active.
Answer
  • True
  • False

Question 6

Question
Leaf veins are the continuation and termination of xylem and phloem from the roots and stems.
Answer
  • True
  • False

Question 7

Question
Which of the following statements is FALSE regarding leaves?
Answer
  • The epidermis is a thin protective layer of cells on the upper and lower surfaces.
  • Immediately under the upper epidermis are densely packed cells that contain chlorophyll, the green pigment necessary in photosynthesis.
  • Inside the lower epidermis are widely spaced cells that permit free movement of water vapor, carbon dioxide and oxygen in and out of the leaves through stomata.
  • Pairs of specialized cells, termed plastid cells, control the opening and closing of stomata.
  • Guard cells respond to light so that stomata are normally open in daylight and closed in the dark

Question 8

Question
The principal male flowering structure is the:
Answer
  • pistil
  • stamen
  • style
  • dioecious

Question 9

Question
The principal female flowering structure is the:
Answer
  • pistil
  • stamen
  • anther
  • monoecious

Question 10

Question
Botanically speaking, a fruit is the plant part that contains the mature, swollen ovary and seed; such as an orange, tomato, squashes, green beans and eggplants.
Answer
  • True
  • False

Question 11

Question
Identify the correct botanical/scientific classification format of the Coast Live Oak.
Answer
  • Quercus Agrifolia (Italisized)
  • Quercus agrifolia
  • Quercus agrifolia (Italicized)
  • quercus agrifolia

Question 12

Question
Like growth, plant development is an integrated expression of a plant's genetic potential and its environment.
Answer
  • True
  • False

Question 13

Question
Photosynthesis is the process by which green plants produce their own carbohydrates, or nutrients, and obtain a source of chemical energy.
Answer
  • True
  • False

Question 14

Question
Plant species vary somewhat in the light levels needed for photosynthesis.
Answer
  • True
  • False

Question 15

Question
In order for a plant to grow and develop normally respiration must occur at a rate that greatly exceeds the photosynthesis rate.
Answer
  • True
  • False

Question 16

Question
The depletion of stored food reserves may reduce the vigor of a plant and its ability to develop high-quality flowers, fruit, or storage organs such as tubers.
Answer
  • True
  • False

Question 17

Question
Most of the water and mineral uptake occurs in roots along the large taproot of a plant's root system through a combination of physical and chemical processes.
Answer
  • True
  • False

Question 18

Question
The time of year when flower induction occurs and the length of time from induction to flowering for a given species are important for home gardeners to know.
Answer
  • True
  • False

Question 21

Question
When soils are severly compacted, water-logged, or are artificially deepened more than a few inches over a plant's root system, oxygen may be insufficient for root respiration. Roots die if these conditions occur for an extended period of time.
Answer
  • True
  • False

Question 22

Question
Does the image display:
Image:
Whorledleaves (binary/octet-stream)
Answer
  • alternate leaf arrangement
  • opposite leaf arrangement
  • whorled leaf arrangement

Question 23

Question
The process of translocation in a plant can also aid in the movement of externally applied foliar fertilizers and pesticides.
Answer
  • True
  • False

Question 24

Question
Most water and nutrient absorbing roots of trees are found in which section of the soil?
Answer
  • upper 12"
  • below 12"
  • below 24"
  • water and nutrient absorbing roots are distributed evenly throughout the soil

Question 25

Question
Which of the following plant tissues contains meristematic tissue?
Answer
  • xylem
  • heartwood
  • phloem
  • vascular cambium

Question 26

Question
