Thigmotropism

The response of a plant to touch.

Hormone

Substance produced in one part of a plant that affects another part of a plant.

Auxins

Cell elongation

Cytokiniens

stimulate cell division and growth of lateral buds, cause dormant seeds to sprout

Gibberellines

The rapid increase in size (fruit)

Ethylene

Ripeing of fruit, a gas.

Gravitropism

The response of a plant to the force of gravity.

Phototropism

The response of a plant to grow towards light.

Cuticle

Protects the leaf from excessive loss of water.

Mesophyll

Where photosynthisis occurs.

Roots

Where the leaves get water for photosynthisis.

Stomata

opening that controls gas exchange and transpiration

Fibrous Root

The primary and secondary roots are the same size. ex:grass

Taproot

One large thick root with secondary roots coming out.

Root Hair

Increase the surface area for maximum water absorbtion.

Roots Function

To get water, and to anchor the plant.

Stems Function

To transport water and for structural support.

Xylem

Water Transportation

Phloem

Nutrient Transportation.

Leaves Fuction

To absorb light for photosynthesis.

Photosynthisis

The sun's energy converted to sugar

Transpiration

The evaporation for water out of the stomata, the loss of water is replaced by the roots.

Gas exchange

The leaves take in carbon dioxide and release oxygen.

Sporangia

round brown spots used to resist drying on the bottom of the fern.

Gymnosperms female location

seed cone on the bottom.

Gymnosperm male location

pollen cone on top

Gymnosperm

Wind pollenation

Angiosperm

Largest and most advanced that have flowers that promote pollenation

Fruit

Structure best insured varried seed dispersal.

Nonvascular

small, no xylem and phloem, no vascular tissue, no true roots, stems, or leaves.

Vascular

have xylem and phloem, have true roots, stems and leaves, large

Dermal Tissue

epidermis, protection, H2O, CO2, and O2 regulation.

Ground Tissue

Mesophyll, contains vascular tissue

How Nonvascular plants transport

Difusion and osmosis
