Pistils = Carples In Magnolia, we see muliple, unfused carpels. Each is considered a pistil.

24
What floral parts are fused?
25
The sepals are fused together. The petals (corolla) are
fused together, and the stamens are fused to the corolla. Two carpels are fused to form a compound pistil.
26
Is the ovary superior or inferior?
27
Superior
28
How many carpels are here?
29
Two
30
What are these small structures?
31
Ovules
32
What floral parts are fused?
33
The sepals, petals and stamens
are fused to form a hypanthium. Four carpels are fused to form the pistil. This can be seen in the four-lobed stigma

Is the ovary superior or inferior?
74
The ovary is superior.
75
What is the structure of lily?
76
This is an ovary as seen in cross section.
77
What is the structure of lily?
78
This is a carpel. A carpel is a megasporophyll that encloses the ovules. This ovary consists of three carpels.
79
What is the structure of lily?
80
An ovule
81
What is the structure of lily?
82
A megaspore mother cell = megasporocyte
83
What is the structure of lily?
84
This is a four-nucleated megagametophyte.
Megagametophyte = embryo sac in the angiosperms.
85
What is the structure of lily?
86
This is an ovule showing the megagametophyte
and nucellus
87
What is the structure of lily?
88
8-nucleted, 7-celled megagametophyte
This is the mature megagametophyte.
89
What is the structure of lily?
90
The central cell of the mature megagametophyte
with two nuclei.
91
What are these cells of lily?
92
The center cell is the egg. The other two are synergids.
Together, these three cells are the egg apparatus
93
What are these cells of lily?
94
These three cells are the antipodals.
95
What is this cell of lily?
96
This is one sperm nucleus undergoing karyogamy with the
egg nucleus to generate the zygote.
97
What is this cell of lily?
98
This is the other sperm nucleus undergoing karyogamy with the two
polar nuclei to generate the primary endosperm nucleus.
99
What is structure of lily?
100
Anther in cross section.
101
What is the structure of lily?
102
One microsporangium of the
four making up the anther.
103
The arrows point to the tapedal layer of a
microsporangium.
104
What are these cells of lily?
105
This is a tetrad of microspores
106
What is the structure of lily?
107
Microgametophyte = pollen grain
108

A strawberry is an aggregate fruit. It is an aggregate of achenes
derived from a single flower with multiple pistils. It is held together by the receptacle which is fleshy.
132
What is the fruit type?
133
A pineapple is a multiple fruit. It is a multiple of berries
derived from a flower shoot. Flowers formed from axillary buds and the resulting fruits melded together.

A raspberry is an aggregate fruit. It is an aggregate of drupes
derived from a single flower with multiple pistils. It forms around the receptacle which is left on the plant when the fruit is picked.
