Teacher Notes:

Tap roots: Carrots with tops

Fibrous roots – weeds, annuals

Bulb roots – onion sets, daffodils

Stems:

Woody – stem of shrub

Herbaceous – flower stem

Tree rings

Xylem – (Prep a few days in advance for best results)

celery, baby’s breath, daisies: put in colored water. For celery, cut the bottom vertically, put one side in red water, one in blue water…students will see the different colors come up the vascular tissue of the celery; baby’s breath will turn color in their petals.

Stomata – purple leaf (wandering jew)

Adaptations:

Cactus – water filled leaves

Pine needles – less surface area

Potatoes – storage of starch (food)

Cones –

Parasitic plants – either pictures or live: mistletoe, Spanish moss

Carnivorous – Venus fly trap

Colored Reference Sheets –

Plant Response

Monocot/Dicot

Plant Response examples –

Vining Plant example (beans, peas)

Phototropism example (turning towards light)

Gravitropism – grow seeds with students – roots grow down. Also you can use a Tupperware with clear shampoo in it and small pebbles…as it turns, the pebbles go towards the ground (example of the starch granules pulling roots down)
