(Plant Groups)
These aquatic plants are thought to be the ancestors of all land plants.
What are green algae (chromophytes)?
This tissue is responsible for transporting water and minerals from the roots to the rest of the plant.
What is xylem?
In addition to anchoring the plant in place and water/mineral absorption, what other function do roots serve?
What is energy storage?
Monocots typically have this many cotyledons in their seeds.
What is one?
Which living mammals were shown to be measly in size compared to the sauropod dinosaurs that used to roam Earth?
What are elephants?
Ferns reproduce using this unicellular reproductive unit.
What are spores?
Found in the growing tips of roots and shoots, this tissue is responsible for primary growth in plants.
What is apical meristem?
These small root structures increase the surface area for absorption of water and minerals.
What are root hairs?
Carrot, a taproot vegetable, belongs to this group of plants.
What are dicots?
What fruit did Iain Stewart eat to demonstrate that plants have developed defence mechanisms to deter organisms from eating it?
What is chilli pepper?
This type of leaf keeps a plant alive when it first sprouts.
What are cotyledons?
This type of ground tissue provides support and structure to the plant and is fortified with lignin.
What is sclerenchyma?
What is the name of the structure responsible for lateral root expansion?
What is the pericycle?

What are bryophytes?
The Casparian Strip is found inside the inner protective layer of a plant. What is the name of the inner protective layer?
What is the endodermis?
The Casparian Strip prevents the passage of water through the cell wall thanks to which hydrophobic molecule?
What is suberin?
Monocots usually have flower parts in multiples of this number.
What is three?
Iain finds a “fossil forest” in which Canadian province?
What is Nova Scotia?

What are angiosperms?
Companion cells keep which type of cell in the phloem alive?
