Botany Unit 3 Exam Practice

Reproducing plants

• germination

• direct seeding

• propagation

• indirect seeding

Self-pollination can occur with

• Complete flowers

• Incomplete flowers

• Both complete and incomplete flowers

“True to seed” - always produce the same plant, commonly accepted as 50+ years old in lineage

• GMO seeds

• Hybrid seeds

• Heirloom seeds

Food storage tissue containing the biomolecules necessary to begin plant growth

• Seed coat

• Endosperm

• Embryo

The first leaves of a newly germinated plant

• True leaves

• Seed coat

• Embryo

• Cotyledon

Which is true of monocots?

• Usually has a taproot system

• Leaves have netted veins

• Vascular bundles arranged in a ring

• Flower parts arranged in multiples of three

Planting in flats separately from where they will grow to maturity

• Direct seeding

• Indirect seeding

• Layering

• Grafting

The hardening off process:

• Prepares the seed coat by damaging it in order to allow water to enter the seed

• Protects the root system by scooping the soil up from underneath the roots

• Prepares seedlings for

  the shock of transplanting

• Damages the seed coat through periods of freezing and thawing

The most common method of seed dispersal

• wind

• water

• gravity

• animals

Commercially, the most commonly used method of asexual reproduction where stems, roots, or leaves are used to reproduce a plant

• Grafting

• Cutting

• Layering

• Budding
