Final Thought Take the names of trees that you know

and try to put them in to the two categories that you now know.

Acronym Write down what you think this word

means.

BASS V LEGSB Bark description (color and texture on twigs) A Alternate around/alternate beside/opposite/whorled S Simple/pinnate/double pinnate/palmateS Shape of tree (without leaves)

V Veins (pinnate/palmate/parallel)

L Lobed/unlobed bladesE Edge (smooth – coarse/finely toothed)G General leaf size (width and length of one blade)S Seeds (describe and rub/draw)

Differences Look at your list of differences and see

if you came up with some of the same answers as the BASS V LEGS.

Question of the day How do plants move food and

nutrients throughout the whole plant?
