Q

Petiole and Blades

A

petiole is the “stem” of the leaf

17
Q

why are angiosperms the only vascular plant that can be either monocot or dicot

A

these classifications only apply to flowering plants (angiosperms) and not other vascular plants like gymnosperms

18
Q

Monocot

A

1 cotyledon when planted

19
Q

Dicot

20
Q

Dicot root

A

star shaped center
little surrounding cells = phloem
big cells in center = xylem

21
Q

Monocot root

A

ring shaped center

22
Q

Dicot leaves

23
Q

Monocot leaves

A

parallel patterns

24
Q

Dicot floral parts

25
Monocot floral part
multiples of 3's
26
Flower Inflorescenes
cluster of flowers
27
Perfect Flower
both male and female layers
28
Imperfect Flower
only one sex
29
Stamen
male layer ( anther makes pollen/sperm ; filament supports)
30

31
Male layer of flower
stamen; androecium
32
female layer of flower
