Plant Structure and Function
How do structures of plants enable life functions?
- Compare and contrast the structures by which vascular and non-vascular plants obtain and retain water, allow for gas exchange for photosynthesis, and allow for long-distance internal transport of water.
- Map onto a phylogenetic tree of plants the locations where innovations for acquiring water, retaining water, exchanging gases, upright stature, and reproduction in the absence of swimming sperm arose.
- Analyze structural and anatomical features that optimize photosynthesis under various environmental conditions such as shading, water deficit, or high temperature.
- Contrast the primary cell wall component of plants, fungi, and bacteria.
- Analyze the roles of cellulose and cell wall matrix components in support, growth, and cell-cell recognition as well as protection against pathogens.
- Categorize defense mechanisms into structural, constitutive biochemical, and induced biochemical responses, evaluating the cost and benefits of each.
- Plants have conducting tissues that transport water, carbohydrates, and nutrients through both passive and active mechanisms.
- Compare and contrast the long distance transport of carbohydrates with that of water and nutrients in a plant.
- Diagram the pathway of carbohydrate transport from a source to a sink, indicating where active transport is required.
- Categorize plant structures and their particular features that facilitate dispersal of the plant in the environment.
- Select a plant structure that is capable of movement and analyze the features that enable it to move.
