Trees and Shrubs
Part 1 Test
| Question | Answer |
|---|---|
| A cross between two different species or generic are indicated by an “x” (lowercase) between parent species. | Naming Hybrids |
| Sometimes, the nomenclature for a hybrid may not show parent species, but an “x” will appear between the genus name and species name. | Naming Hybrids |
| Individuals exhibit characteristics such as color, form, absence of specific features (different from norm of species). These traits may also be found in the offspring produced by seed. | Varieties |
| Individuals may exhibit characteristics such as color, form or fruit that are only continued in offspring produced asexually. Cultivars identified in the Latin name by the lowercase letters “cv” | Cultivar |
| Sometimes, the genus name will be followed by sp., used when describing one member of the genus, or single species | abbreviations for singular |
| Sometimes, the genus name will be followed by spp., would be used when describing several or all species belonging to the genus | abbreviations for plural |
| The ordering of items into groups having common characteristics and into a hierarchy of successively more inclusive groups. | Classification |
| Also known as gymnosperms | Pinophyta |
| Wood composed primarilyof tracheids | Pinophyta |
| It means “naked seed” | gymnosperm |
| Also known as angiosperms | Magnoliophyta |
| Usually net like (veins in leaves). Usually in fours or fives (flower parts). Inner ring (arrangements). | Dicots (two cotyledons) |
| Veins in leaves (usually parallel). Flower parts (multiples of three). Arrangement (scattered). | Monocots (one cotyledons) |
| Responsible for photosynthesis, exchange of gases, transpiration | Structure and Functions of Foliage |
| T/F: Photosynthesis occurs in recent growth of stems where chloroplasts are present. | True |
| Stage of photosynthesis that concerns the role of pigments such as chlorophyll (absorbs blue and red light) and carotenoids (absorbs blue-green light). | The light dependent stage |
| Stage of photosynthesis that concerns the formation of glucose and oxygen from CO2 and H2O. | The light independent stage |
| Sugars broken down and used for growth, flower production, and fruit. Production in formation of tissue. Energy released. Production of CO2, H2O and heat. | Respiration |
| Is the loss of water vapor through plant parts. Most water vapor is moved through the stomata on the underside of the leaves. Some water vapor may also be moved through lenticels on the stem. | Transpiration |
| Balances need for air with loss of water. | Transpiration Compromise |
| Non-conducting tissue, acts as protection against disease, insects, and temperature. | Cork |
| Roots that are located in the upper 25 cm of the soil which provide the tree with most of the moisture and nutrient requirements. | Feeder Roots |
| Roots that are generally important to trees at a young age for stability and development. | Tap Roots |
| Many species do not have a dominant heart root or Root system. These have shallow fibrous root systems. | Fibrous Roots |
| Some genera have roots that grow at an angle from the root collar (one dominant group known as the taproot which grows vertically). | Heart Roots |
| Requires the fertilization of __________ of female flowers by pollen from the _________ flowers. | pistils (Pistillate)/ stamens (staminate) |
| T/F: Cross-pollinated individuals are usually faster growing than those that are self pollinated. | True |
| The genetic composition of an organism. | Genotype |
| The visible characteristics of an organism, influenced by: Genetic composition of the species. Interaction between species. Environmental factors. Etc. | Phenotype |
| “seed leaves” | cotyledons |
| There is no seed coat or cotyledons (seed leaves) which is why we call conifers naked seed (gymnosperms). | Spore |
| Consists of an embryonic plant together with a store of food, all surrounded by a protective coat (essentially three parts). | Seed |
| Flower types that have all for flower parts (sepals, petals, stamens and pistil). | Complete Flowers |
| Flower types are lacking any one of the four parts of a complete flower, lacking either sepals or petals. | Incomplete Flowers |
| Flower types that have both staminate and pistillate flower parts contained in one flower, but may lack sepals and or petals. | Perfect Flowers |
| Unisexual flowers (often catkins) which lack either the staminate or pistillate flower parts. | Imperfect Flowers |
| Transfer of pollen from a stamen to a position to come in contact with an egg. | Pollination |
| Arrangement of flowers on plants that have separate male and female flowers on the same plant. | Monoecious |
| Arrangement of flowers on plants that have male (staminate) flowers on one plant, and female (pistillate) flowers on another plant. | Dioecious |
| All the flowers of an individual contains both male and female parts in the same structure (the flowers are perfect). | Synoecious |
| Type of seeds that do not split open when they are mature. | Indehiscent Fruits (dry fruit) |
| Type of seeds that do split open when mature. | Dehiscent Fruit (dry fruit) |
| Fruits that have a moist endosperm development, comprised of a fleshy exocarp, stony endocarp and seed. | Drupe (fleshy fruit) |
| Fruits that have a moist endosperm development, comprised of fleshy mesocarp, fibrous endocarp and seed. | Pome (fleshy fruit) |
| Characteristic of a seed that prevents germination during unsuitable or disadvantageous times. | Dormancy |
| The conditions necessary to break dormancy and initiate germination (natural or artificial). | Stratification |
