Q

taught at Tuskegee Institute and founds several ways that improved life with peanuts ect.

A

George Washington Carver

62
Q

the principal parts of a flower

A

buds

64
Q

protect the bud in winter from frost injury and from drying out

A

bud scale

65
Q

rings that circle the stem; indicate where last year’s growth started

A

bud-scale scar

66
Q

areas where leaves are growing or have grown

69
Q

Stems grow in length at the tips of their branches

A

primary growth

70
Q

a woody dicot has three areas

A

bark, wood, and pith

Q

If you have a freshly cut, growing woody stem, you can easily peel the bark off. Underneath the bark, the stem is hard and white.

100
Q

sharp special stems

A

thorns

101
Q

which are commonly found in dicots, penetrate the soil with relatively little branching

A

taproots

102
Q

have no main section but spread out with very thin roots, forming a tangled mass in shallow soil

A

103
Q

Some of the epidermal cells develop into long, finger-like projections
