5th Yr Biology


Test left for class.
Please answer all questions in this test on Transport in Flowering Plants.

  1. Define the term root pressure.
  2. Define the term transpiration.
  3. Describe the uptake of water into the plant.  In your answer, refer to each of the following; root hairs, root cortex, xylem, osmosis, diffusion, root pressure.
  4. Describe the process of water transport through the plant.  In your answer, refer to each of the following; root hairs, root cortex, xylem, osmosis, diffusion, root pressure, transpiration, stomata.
  5. Describe the uptake and process of transport of minerals through the plant.
  6. State two sources of carbon-dioxide to plants.
  7. Name the pores in leaves through which gas exchange occurs.
  8. Name the tissue in which the carbohydrates produced in photosynthesis are transported.
  9. Give one example of a root modified for food storage.
  10. Give one example of a stem modified for food storage.
  11. Give one example of a leaf modified for food storage.
Higher Level:

  1. Who proposed the Cohesion-Tension Model of Xylem transport?
  2. Describe the Cohesion-Tension Model of Xylem transport.  In your answer, include the following; attractive forces of water molecules, cohesive property, role of transpiration.

LC - Mind Maps on Flowering Plants

5th Yr Biology: Mind Map on Flowering Plants for Wednesday
Here is an example from 5th year 2012 to get you started

LC - Cohesion Tension Model

Here are 2 intersesting clips to illustrate the Cohesion-Tension Model proposed by Dixon and Joly

LC Biology Experiments - Use starch agar plates to show digestive activity during germination



Method:
Soak broad beans in distilled water for 2 days
Swab lab bench with disinfectant
Label 1st sterile plate ‘Raw’, 2nd ‘boiled’. Initial and date
Kill two of the seeds by boiling for 5 mins (control)
Split each seed in half to separate the cotyledons
Sterilise all seeds by soaking in disinfectant for 10 mins
Rinse seeds twice in sterilised water
Using a sterilised forceps place seed halves face down on the appropriate agar plate
Re-flame forceps and re-swab bench
Incubate plates upright at 18-20C for 48 hrs
Remove seeds
Flood plates with iodine and leave for 2mins
Pour off Iodine solution
Note pattern of starch digestion by holding plate up to light
Conclusion:
A pattern should appear where raw seeds germinated and digested starch on agar plate. The boiled seeds should not have germinated as enzymes required should have been denatured. This plate should be predominantly blue/black
