Transcript of Topic 9 Plant science - review

9.1.2 Outline three differences between the structures of dicotyledonous and monocotyledonous plants.
9.1.4 Identify modifications of roots, stems and leaves for different functions
Function: anchorage and water uptake
Modifications: nutrient storage, e.g. tuberous roots such as cassava, sweet potato and yam
Function: photosynthesis and gas exchange
Modifications: tendrils for support; bulbs for nutrient storage
Function: support and transport
Modifications: stem tubers for storage of nutrients, e.g. potatoes, ginger
9.2 Transport in angiosperms
9.3 Reproduction in angiosperms
9.1 Plant struture and growth
Mineral ions move into the root hair cells by active trasnport...
In active transport, mineral ions are moved against a concentration gradient, which requires:
1) numerous mitochondria in root hair cells for ATP production
2) protein channels in the cell membrane for active transport
3) oxygen in the soil that is absorbed by root hairs for cell respiration.
Other cations include:
Na+, Ca2+
9.2.4 State that terrestrial plants support themselves by means of thickened cellulose, cell turgor and lignified xylem.
9.2.5 Define transpiration.
9.2.6 Explain how water is carried by the transpiration stream, including the structure of xylem vessels, transpiration pull, cohesion, adhesion and evaporation.
9.2.7 State that guard cells can regulate transpiration by opening and closing stomata.
9.2.9 Explain how the abiotic factors light, temperature, wind and humidity, affect the rate of transpiration in a typical terrestrial plant.
