Cite all sources using the CSE method (or ISO 690 Numerical in Word. Highlight all objective 1 command terms in yellow and complete these before class. Highlight all objective 2 and 3 command terms in green – these will be part of the discussions in class. After class, go back and review them.

Complete the self-assessment rubric before submitting to Moodle. Avoid printing this if possible.

1.

Define vascular plant.

Vascular plants (tracheophytes) have conductive tissues (a vascular system) for transporting water, minerals and nutrients throughout the plant. (1)

2.

Distinguish between angiospermophytes and gymnospermophytes.

3.

Complete the table below to distinguish between monocotyledons and dicotyledons.

You may use labeled diagrams if you wish.

Flowers

For much of the remainder of the unit we focus on dicotyledons (dicots), which are examples of angiosperms. Be sure to use dicot examples in any research you carry out.
