Which plant produces tuberous roots often mistaken for bulbs but are actually swollen root structures?
Dahlia
Gladiolus
Iris
Tulip
Dahlia plants form tuberous roots, which store nutrients but are not true bulbs. These tubers produce new shoots each spring. Gardeners often confuse them with bulbs due to their rounded shape. Learn about dahlia tubers.
Which pigment is primarily responsible for the blue coloration in Hydrangea flowers?
Chlorophyll
Carotenoids
Betalains
Anthocyanins
Anthocyanins are water-soluble pigments that can appear red, purple, or blue depending on pH. In acidic soils, hydrangea flowers often turn blue due to aluminum uptake and anthocyanin chemistry. Carotenoids and betalains contribute different hues. More on anthocyanins.
In orchid species like Ophrys apifera, what pollination strategy mimics the appearance of female insects?
Deceptive pollination
Nectar reward
Self-pollination
Wind pollination
Ophrys orchids use sexual deception by producing flowers that visually and chemically mimic female insects, luring males to attempt mating. This ensures pollinia transfer without offering nectar. Many orchids employ unique pollination tactics. Read about Ophrys pollination.
In tulips, the undifferentiated segments of the perianth are called what?
Tepals
Stamens
Corolla parts
Bracts
In many monocots like tulips, sepals and petals are similar in appearance and are collectively termed tepals. This undifferentiated perianth simplifies identification in some plant families. True petals and sepals differ in form. Learn about tepals.
According to the ABC model of floral development, which gene functions specify petal identity?
B + C
A + B
C only
A + C
In the ABC model, A-class genes alone specify sepals, A + B specify petals, B + C specify stamens, and C alone specifies carpels. This framework explains organ identity in many flowering plants. Explore the ABC model.
Which structures are modified leaves that subtend flowers or inflorescences, often mistaken for petals?
Sepals
Stamens
Bracts
Petals
Bracts are specialized or modified leaves located at the base of flower stalks, sometimes brightly colored to attract pollinators. Poinsettias and bougainvillea are classic examples. True petals and sepals form the flowers perianth. Read about bracts.
Which flower opens its blooms primarily at night rather than during daylight hours?
Rose
Sunflower
Daisy
Moonflower
Moonflowers (Ipomoea spp.) open their fragrant blooms at dusk and remain open through the night, attracting nocturnal pollinators like moths. Sunflowers and daisies open during daylight. This adaptation maximizes pollination success in low light. Learn about moonflower phenology.
Which receptor protein mediates phototropism, causing stems and flowers to bend toward light?
Phototropin
Phytochrome
Auxin
Cryptochrome
Phototropins are blue-light photoreceptors that trigger directional growth toward light sources. They regulate auxin distribution, resulting in bending. Phytochromes detect red/far-red light, and cryptochromes detect blue light for other responses. More on phototropins.
Which group of pigments is responsible for the yellow coloration in daffodils?
Betalains
Chlorophyll
Anthocyanins
Carotenoids
Carotenoids are lipid-soluble pigments that produce yellow, orange, and red colors in many flowers and fruits. In daffodils, carotenoids like lutein give the bright yellow hue. Anthocyanins produce red to blue colors, while betalains are found in beets. Discover more about carotenoids.
Which protein, also known as florigen, moves from leaves to the shoot apical meristem to induce flowering?
FT protein
Abscisic acid
Auxin
Gibberellin
FT (FLOWERING LOCUS T) protein is the mobile signal known as florigen. It is synthesized in leaves under inductive photoperiods and transported to the meristem to trigger floral development. This discovery solved a century-old mystery in plant physiology. Read about florigen and FT protein.

Cheat Sheet
Floral Symmetry -
Radial (actinomorphic) flowers like daisies display petals evenly around a central point, making them easy to identify by multiple lines of symmetry (Royal Horticultural Society). Bilateral (zygomorphic) blooms, such as snapdragons, have a single plane of symmetry and often indicate specialized pollinators. Mnemonic: "Radars rotate, bilaterals bisect."
Floral Formula Basics -
Floral formulas succinctly describe sepal (K), petal (C), stamen (A), and carpel (G) counts - e.g., Iris: ✶ K3 C3 A3+3 G(3) (Botanical Society of America). This shorthand helps compare species quickly and highlights key identification features in just a few characters. Practice by writing formulas for common garden blooms to strengthen recall.
Monocot vs. Dicot Characteristics -
Monocots typically have floral parts in multiples of three and parallel leaf venation, while dicots feature parts in fours or fives and netted veins (University of California Agriculture & Natural Resources). Observing a lily's three petals versus a rose's five can immediately hint at its group. Use the "3s and parallels" versus "4 - 5s and nets" rule as a quick field test.
Spotting Iris vs. Gladiolus -
Iris blooms boast three upright "standards" and three drooping "falls," whereas Gladiolus flowers line a tall spike with fan-shaped leaves (American Iris Society). Remember: "Iris is tiered, Gladiolus guards the gate." Visualizing these unique arrangements will sharpen your identification accuracy.
Color Patterns & Nectar Guides -
Many flowers display ultraviolet nectar guides invisible to humans but clear to pollinators, aiding in species recognition (Journal of Pollination Ecology). Look for contrasting veins or spots leading to the bloom's center, which often indicate flower identity and pollination strategy. A handheld UV flashlight can reveal these hidden markings for fun, hands-on practice.
