Evolve-a-Plant Work Sheet

When living things change their form and function to adapt to new environments, this is called evolution. It takes many generations for evolution to occur. Only the changes that help the living organism to survive will be reproduced.

Change this plant so that it can live in new environments. Fill in the boxes to show your thinking.

Environment  Organism Growth Habits  Reasons

Temperate Grasslands

 

20 - 85 Degrees Fahrenheit

 

Rainfall: 20 inches

 

Grows in large dense clumps Height: 18 inches

All green stems are hollow tubes.

Wind Pollinated: pollen forms on tall spikes

Seed forms on lower irregular structure.

Small bulb above roots

Closely packed plants make wind pollination efficient.

 

Sturdy green spikes function as leaves, resist wind damage.

Tall spikes receive more wind. Pollen travels farther before falling to ground.

Seed-forming structure has large area, is lower than pollen spikes so that pollen will fall on it.

Bulb stores resources over the winter to allow for quick growth spurt in spring, resistance to occasional droughts.
