• Angiosperms have seeds that develop in a ____________ structure. Gymnosperm seeds do not develop in a _______________ structure.

• Vascular tissue includes the xylem and phloem which conduct ________, _____________, and __________ ions around the plant.

• The palisade mesophyll is located in the upper portion of the leaf. Here, ________ is readily available. The PM has many ___________, in order to ensure maximum photosynthesis.

• Phloem, cambium, and xylem

• Vascular

• Protected/enclosed

•Water, nutrients, mineral ions

Dicotyledonous plants have vascular tissue that is ______________ ____ ___ ___________.

Monocots have flowers in multiples of _________. Dicots have flowers in multiples of ______________.

Monocots have a ___________ root system. Dicots have a ___________.

The apical meristem controls ____________ growth.

• Scattered

• Arranged in a ring

• 3, 4 0r 5.

• Fibrous, taproot

• Upward

9.2• Terrestrial plants support themselves with thickened _________, cell __________, and lignified __________.

• The loss of water vapor from plants is called _______________.

• Root _________ increase the surface area over which water and mineral ions may be absorbed.

• A ___________ is a growth or movement in response to external such as sunlight. (Photo________)

• __________ are plant hormones that cause positive photo__________ of plants and seedlings.

• Cellulose, turgor, xylem.

• Transpiration

• Hairs

• Tropism

• Auxins, phototropism

Lots of light increases/decreases the rate of transpiration.

Higher humidity increases/decreases the rate of transpiration.

Higher temperature increases/decreases the rate of transpiration.

Wind increases/decreases the rate of transpiration.

Name a few adaptations of xerophytes (plants adapted to arid conditions) to decrease water loss by transpiration.

• Increases

• Decreases

• Increases

• Increases

• Small thick leaves (reduced surface area), waxy cuticle, reduced number of stomata, hair-like cells that trap water vapor on leaf surface, water storage (in roots, leaves, stems)

9.3

• Name the two general types of pollination.

• Plants show two generations in their lives:

• Name some pollen vectors ( means by which pollen can be carried from the anther of a plant to the stigma)

• Name the conditions needed for a seed to germinate

• Gibberellin is a plant __________ _______.

• Photoperiodism is a plant’s response to ________

• Self-pollination and cross-pollination

• Gametophyte generation (haploid, produces plant gametes by mitosis) and sporophyte generation (diploid, produces spores by meiosis)

• Wind, insects, birds, water, other animals

• Water to rehydrate seed tissues, oxygen for aerobic respiration and production of ATP, appropriate temperature for enzyme action.

• Growth hormone, triggers production of amylase, starch ---maltose----glucose----cellulose----new cell walls

• Light--- Long Day Plants bloom when days are longest and nights are shortest• Short Day Plants bloom when days are shorter (spring, late summer, autums)• Day neutral- plants flower regardless of day length
