Part 1: Ecosystem observations i.

Ecosystem Observations

Write down any observations you’ve made about your ecosystem (feel free to include illustrations):

Water Quality Measurements Nitrate mg/L: Phosphate mg/L: pH: Cond. uS/cm: DO mg/L: Temperature degC:

Part 2: Alternation of Generations How do you produce haploid spores?

How do you produce a diploid zygote?

How are gametes produced by the gametophyte?

Part 3: Non-vascular Plants What adaptation allowed the non-vascular plants to adapt to land?

What is a consequence of not having vascular tissue? How does this affect non-vascular plants?

Describe the appearance of the Hyaline cells in Sphagnum moss. How might the structure inform us of its function? (Feel free to make an illustration)

Part 4: Seedless Vascular Plants Observe the Selaginella and Psilotum. Where are the sporangia? What is their function?

In ferns, the sporangia are clustered together in sori. After the sori dries out, the spores are released. Why might this be advantageous?

Why is the fern life-cycle restricted by water?

Part 5: Non-flowering Seed Plants How would you tell Cycads and Ferns apart?

Why is flagellated sperm considered “primitive” trait?

In coniferous plants, why do male cones drop off while female cones remain on the shoot?

Where are the gametophytes in Coniferous plants? (Male/Female) – You can use a diagram to illustrate the example

Part 6: Flowering Plants What two cells in the ovule are being fertilised during “double fertilisation”?

Fruits are a key to the dispersal of seeds. Design a fruit with an adaptation towards a particular type of dispersal (use your imagination!) – What mode of dispersal have you chosen? What structures have you included in your design? How do these structures aid in dispersal? (you can have a written description and/or an illustration)

Part 7: Literature and Referencing What is the aim of your chosen paper? What is the hypothesis?...
