Question | Answer |
What is dominant in angiosperms? | Sporophyte |
Where are they found? | Many environments |
How large can they be? | 1mm-100m |
How do most get food? | Autotrophic, some are parasites |
Angiosperm in Greek means | Vessel seed |
True parasite | Doder |
Hemiparasitic | Mistletoe |
Epiphytes | Air plants. Attaches to substrate such as another plant or a side of a building |
Examples of an epiphyte | Spanish moss, cacti, ferns |
What do we use angiosperms for? | Food, medicine, makeup, cotton, lumber |
Wheat are angiosperms famous for? | Flowers |
What are flowers? | Exclusive reproductive organs |
What emsures pollination? | Color, texture, and nectar |
How often do they shed leaves? | Deciduous, shed leaves in winter or during a drought |
Herbaceous | Little to mnk woody tissue |
Example of herbaceous | Peas |
Example of woody | Apple tree |
Annuals | Life cycle in one seasom |
Annual example | Zinnia |
Biennials | Life is completed in two growing seasons |
Biennials example | Parsley |
Perennials | Life is longer than two seasons |
Perennial example | Tulips |
Seed | Ripened ovule of a plant that contains an embryo houdsed in a protective coat and is nourished by stored food |
Where is fruit from? | Plant ovary |
What do fruits do? | House, protect, nourish, and aid in seed dissemination |
Vegetables | Edible part derived from petioles, leaves, roots, stumps, or flowers |
Examples of specific pollinators | Bees, hummingbirds, bats |
Ovules | Encased within integumemt supplied by the parent plant |
Diploid tissue around ovule | Integument |
Double fertilization | Egg and double nutritive endosperm form |
Tracheids and xylem | Possesses vessels that transports water |
Dicots | Seed contains two cotyledons |
Cotyledons | Seed leaf weigh nutrients to nourish embryo. |
Monicotyledons | Contains a single cotyledon |
What is the first evident leaf after germination? | Cotyledon |
Magnoliophyta | Flowering plants |
Anthophyta | Flowering plants |
What are the two classes? | Dicotyledons and monocotyledons |
Dicotyledones | Magnoliopsida |
Monocotyledons | Liliopsida |
What do new schemes do? | Divides angiosperms into basal dicots, eudicots, and monocots |
Paleodicots | Basal dicots |
Basal dicots | Wsyee lilies, avocado, and magnolias |
What do monocotes and basal dicots have in common? | Monosulcste pollen |
Monosulcate pollen | A linear thin, furrow-like groove (sulcas) on the surface of the grain and one pore |
Eucotyledons | True dicots. Has tricolpate pollen |
Tricolpate pollen | Has three long grooved apertures (pores) on the surface |
Eudicot examples | Roses, oak trees, sunflowers, cabbage |
Monocots evolved from | Dicots |
Monocot examples | Cattails, corn, orchids, palms, and bananas |
4 basal dicots | Nymphaeales, Piperales, Laurales, Magnoliales |
Nymphaeales | Aquatic plants with floating leaves. Water Lillies and lotus |
Piperales | Shrubs, herbs, small trees, black pepper, vine pepper, and wild ginger |
Laurales | Once placed with Magnolias. Sassafras, cinnamon, and avacado |
Magnoliales | Best known. Magnolia, sweet bay, nutmeg, tulip trees |
Many dicots are now considered | Eudicots |
Consists of 1\4 of all living angiosperms | Monocots |
Monocots diverged from | Basal dicots 90 million years ago |
Monocots play a role in | Floral and horticultural industries |
Inflorescence | Cluster of flowers |
Largest unnranched inflorescence | Corpse flower |
Who found the corpse flower | Odoardo Beccari |
Largest bramnched inflorescence | Talipot palm |
Largest flower | Corpse flower |
Smallest flower | A type of duckweed |
Peduncle/pedicels | Specialized stalk(s) |
Flowers begin from a | Penduncle or pedicels |
The penduncle forms the | Receptacle |
Receptacle | Swollen region tjhsat contains other floral parts in whorls |
Outermost whorl | Composed of leaf like green sepals |
Sepals form | Calyx |
Calyx | Protects flower while it develops in the bud |
Petals form | The corolla |
Calyx and corolla make up | The perianth |
Male portion of flowers | Stamen |
Stamen | Comsists of filament (stalk) and the saclike anther |
Anther | Produces pollen |
Stamens make up | Androecium |
How do anthers release pollen.? | Splitting open (daisy) or released from pores on anther tip (azaleas) |
Female portion | Pistil (carpel) which has sticky kmon called xtig!a at the top of a style which leads to the ovary |
Hypogynous | Superior, calyx and corolla attached to receptacle at base of ovary |
Epigynous | Inferior, calyx and corolla at top of ovary |
Perigynous | Semi-inferior, calyx and corolla found on a cup shapesd structure surrounding the receptacle |
Hypogynous example | Grape, honeysuckle, quince |
Epigynous example | Blueberry, watermelon, pear |
Perigynous example | Crape myrtle,cherry, Pyracantha |
Ovary forms | Fruit |
1+ carpels | Main portion of ovary |
Carpel (s) collectively known as | Gynoecium |
Number of carpels | Number of divisions in the stigma (each section of a tomato) |
Complete flowers | Possess sepals, petals, stamens, and pistils |
Incomplete flowers | Lack one or more sepals, petals, stamens, or pistils |
Perfect flower | Both sexes (stamen and pistil) |
Imperfect flower | One sex |
Staminate | Only stamens (male) |
Pistillate | Only pistils (female) |
Actinomorphic | Radially symmetrical. All petals are the same size |
Actinomorphic example | Azaeleas, buttercups, roses |
Zygomorphic | Bilaterally symmetrical. Two or more petal shapes |
Zygomorphic example | Orchid, foxglove, snapdragon |
Catkins (4 facts) | 1)Dutch for kitten 2)drooping slim inflorescence 3)lack petals or have petals that look like a kitten's tail 4)unisex flowers arranged around stem |
Grasses | 1)Flowers are inflorescence 2)basal sheath encompasses the culm down to the node |
culm | Grass stem |
Node | Point of origin |
Grass internodes | Hallow |
Leaf blade grows | Away from culm |
Ligule | Membranous scale found at junction of the basal sheath and leaf blade |
Auricles | Tiny projections near the has of the leaf blade |
Spikelet | Extension of penduncle, conmsisting of many small florets |
Floret | External glume |
Within the floret | One pistil, three stamens, the ovary , and the scale-like lodicule |
