Learning Intentions and Timeline Block:____

Learning Goal: How are plants structurally adapted for survival?

Concept 1: Analyzing the structure, growth, development and nutrition of plants (Ch 35, 37)

Plant Structure, Growth, and Development

You must know:

o The function of xylem and phloem tissue

o The specific functions of tracheids, vessels, sieve-tube elements, and companion cells.

o The correlation between primary growth and apical meristems verses secondary growth and lateral meristems.

❖ Refer to pg 207-210 in Holtzclaw, Ch 35 in Campbell and media resources

Soil and Plant Nutrition

You must know:

o The difference between macronutrients and micronutrients.

o The importance of mutualistic relationships between plant roots and the bacteria and fungi that grow in the rhizosphere.

o Examples of nonmutualistic nutritional adaptations in plants.

❖ Refer to pg 215-216 in Holtzclaw, Ch 37 in Campbell and media resources

Concept 2: Analyzing the reproduction of angiosperms and modifications through biotechnology (Ch 38)

Angiosperm Reproduction and Biotechnology

You must know:

o The process of double fertilization, a unique feature of angiosperms.

o The relationship between seed and fruit.

o The structure and functions of all parts of the flower

❖ Refer to pg 216-219 in Holtzclaw, Ch 38 in Campbell and media resources

Concept 3: Analyzing how plants detect and defend themselves against herbivores and environmental stresses (Ch 39)

Plant Responses to Internal and External Signals

You must know:

o The three steps to a signal transduction pathway

o The role of auxins in plants.

o The survival benefits of phototropism and gravitropism.

o How phototropism determines when flowering occurs.

❖ Refer to pg 219-222 in Holtzclaw, Ch 39 in Campbell and media resources

Concept 4: Analyzing how water and nutrients move through a plant (Ch 36 and AP Lab 9)

Acquisition and Transport in Vascular Plants

You must know:

o The role of passive transport, active transport, and cotransport in plant transport.

o The role of diffusion, active transport, and bulk flow in the movement of water and nutrients in plants.

o How the transpiration cohesion-tension mechanism explains water movement in plants.

o How pressure flow explains translocation.

❖ Refer to pg 211-215 in Holtzclaw, Ch 36 in Campbell and media resources

Lab 9: Transpiration

You must know:

o The role of water potential and transpiration in the movement of water from roots to leaves.

o The effects of various environmental conditions on the rate of transpiration.

o How to identify xylem and phloem and relate their structure to their function.

❖ Refer to pg 346-351 in Holtzclaw, Lab 9 in LabBench
