  1. Wisconsin Fast Plants Lesson 5

  2. 1. General Information • Life cycle lasts 35-40 days • Cycle is from seedling to new generation seedling • Let us take a look at the 1st 28 days of the fast plant cycle • Needs a constant source of bright light • The tips must be within 5 cm of the light source to be effective.

  3. 2. Flowering • Occurs 13 days after germination • Germination: process in which a seed or spore emerges from a period of dormancy – it sprouts • Seeds are harvested 20-25 days after pollination • Harvested: full growth

  4. 3. Genetics • Anthocyanin: purple pigment of fast plant • Color seen in the leaves and stems • Triggered by sunlight • Dominant genetic trait • Dominant: capital letter; ex “P” – means you see the trait • Recessive: lowercase letter; ex “p” – means you do not see the trait

  5. 4. Seeds • Monocots • Grasses (corn, rye) & grains (rice, wheat) • Protective seed coat • 1 cotyledon: seed leaf in embryo • Endosperm surrounds embryo • Endosperm – food storing tissue • Cotyledon stays below ground when seed sprouts • Absorbs nutrients from endosperm • Transports nutrients to seedling

  6. B. Dicots • Beans, peanuts, peas, apples, broccoli; shrubs; trees • Protected by seed coat • 2 cotyledons • At full growth, cotyledons emerge from soil • Seeds separate into two halves; monocots do not

  7. 5. Roots • Monocots: fibrous roots - spread and branch out under ground • Anchor plant • Dicots: 1 long, thick root (taproot) • Small, secondary roots grow from taproot

  8. 6. Stems • Tubes that carry food downward and water and nutrients upward in a plant • Monocots: scattered throughout stems • no pattern • Dicots: tubes arranged in a ring around center of stem

  9. 7. Leaves • Monocots: parallel veins • Dicots: veins intersect forming branching pattern

  10. 8. Flowers • Monocots: flower parts in multiples of 3 • Ex: 3 pedals, 3 sepals, 6 stamens • Ex: Lilies, Spiderwort, Dayflower, Bamboo • Dicots: Flower parts varied; multiples of 2, 4 or 5 • Ex: Rose, Bellflower, Fast Plant, Calendula Plant
