1Which of the following statements is FALSE regarding plant meristems?
- AApical meristems are found in shoot tips, root tips and buds and are responsible for the increase in the length of these plant parts
- BLateral meristem, sometimes referred to as the cambium, is responsible for the increase in stem and root diameter or thickness
- CAll active meristems receive priority for the food material and minerals available within the plant and are often referred to as sinks
- DMeristematic areas encompass a large mass of cells
2ALL 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- ATrue
- BFalse
3Roots require water and food material produced in the shoots, but not oxygen in order to function and grow properly.
- ATrue
- BFalse
4Plants with separate male and female flowers on the same plant are termed dioecious.
- ATrue
- BFalse
5Buds 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.
- ATrue
- BFalse
6Leaf veins are the continuation and termination of xylem and phloem from the roots and stems.
- ATrue
- BFalse
7Which of the following statements is FALSE regarding leaves?
- AThe epidermis is a thin protective layer of cells on the upper and lower surfaces.
- BImmediately under the upper epidermis are densely packed cells that contain chlorophyll, the green pigment necessary in photosynthesis.
- CInside 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.
- DPairs of specialized cells, termed plastid cells, control the opening and closing of stomata.
- EGuard cells respond to light so that stomata are normally open in daylight and closed in the dark
8The principal male flowering structure is the:
- Apistil
- Bstamen
- Cstyle
- Ddioecious
9The principal female flowering structure is the:
- Apistil
- Bstamen
- Canther
- Dmonoecious
10Botanically 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.
- ATrue
- BFalse
11Identify the correct botanical/scientific classification format of the Coast Live Oak.
- AQuercus Agrifolia (Italisized)
- BQuercus agrifolia
- CQuercus agrifolia (Italicized)
- Dquercus agrifolia
12Like growth, plant development is an integrated expression of a plant's genetic potential and its environment.
- ATrue
- BFalse
13Photosynthesis is the process by which green plants produce their own carbohydrates, or nutrients, and obtain a source of chemical energy.
- ATrue
- BFalse
14Plant species vary somewhat in the light levels needed for photosynthesis.
- ATrue
- BFalse
15In order for a plant to grow and develop normally respiration must occur at a rate that greatly exceeds the photosynthesis rate.
- ATrue
- BFalse
16The 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.
- ATrue
- BFalse
17Most 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.
- ATrue
- BFalse
18The 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.
- ATrue
- BFalse
19Does the image display:
- Aparallel venation
- Bpinnate venation
- Cpalmate venation
20From left to right, the image displays which order of leaf arrangements?
- ASimple, pinnately compound, palmately compound
- BPalmatelycompound, simple, pinnately compound
- CSimple, palmately compound, pinnately compound
21When 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.
- ATrue
- BFalse
22Does the image display:
- Aalternate leaf arrangement
- Bopposite leaf arrangement
- Cwhorled leaf arrangement
23The process of translocation in a plant can also aid in the movement of externally applied foliar fertilizers and pesticides.
- ATrue
- BFalse
24Most water and nutrient absorbing roots of trees are found in which section of the soil?
- Aupper 12"
- Bbelow 12"
- Cbelow 24"
- Dwater and nutrient absorbing roots are distributed evenly throughout the soil
25Which of the following plant tissues contains meristematic tissue?
- Axylem
- Bheartwood
- Cphloem
- Dvascular cambium
26The vascular cambium of a dicot tree is generally located:
- Anear the center of the trunk in the heartwood
- Bin the roots near the basal flare
- Con the outside of the trunk near to the bark and phloem
- Devenly distributed throughout the trunk of the tree
