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

21 Anther

22

23 Stamen

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

68 Filament

69 What are the floral parts?

70 Petals

71 What are the floral parts?

72 Sepals

73 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 Choose all that apply: Imperfect ----- Monoecious

109 Imperfect This plant is dioecious.

110 Choose all that apply: Imperfect --- Monoecious

111 Imperfect and Monoecious

112 What is the fruit type?

113 Achene

114 What is the fruit type?

115 Nut

116 What is the fruit type?

117 Drupe

118 What is the fruit type?

119 Berry – the inner hard part is derived from the integuments of the ovule.

120 What is the fruit type?

121 Berry

122 What is the fruit type?

123 Capsule

124 What is the fruit type?

125 Berry

126 What is the fruit type?

127 Berry

128 What is the fruit type?

129 Berry

130 What is the fruit type?

131 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.

134 What is the fruit type?

135 Berry

136 What is the fruit type?

137 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.
