IB Biology Review game: Plants

1. IB Biology Review game: Plants 9.1, 9.2, & 9.3

2. Questions: 9.1 • What makes up the vascular bundle of a plant? • Land plants are divided into three groups: Non-________ land plants, seedless _________ plants, and seeded ____________ plants • 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.

3. Phloem, cambium, and xylem • Vascular • Protected/enclosed • Water, nutrients, mineral ions

4. Fill in the blank • Monocotyledonous plants have vascular tissue that is _______________ . 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.

5. Scattered • Arranged in a ring • 3, 4 0r 5. • Fibrous, taproot • Upward

6. 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.

7. Cellulose, turgor, xylem. • Transpiration • Hairs • Tropism • Auxins, phototropism

8. 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.

9. 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)

10. 9.3

11. 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 ________

12. 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
