PHYTOGRAPHY: THE FRUIT

I. INTRODUCTION
The fruit is a matured ovary containing one or more seeds. It is composed of the exocarp, mesocarp and the endocarp. Many floral parts aside from the ovary are persistent and therefore could still be seen in mature fruits. Some examples are the receptacles (apple, sepals (eggplant), style (corn) and many more. There are several variations of the fruit morphology and they are all important in the study of plant taxonomy and plant identification.
II. MATERIALS
Vigna sesquipedalis Dolichos lablab
Psidium guajava Anona squamosa
Fragaria vesca Ananas comosus
Cucumis sativus Cucurbita moschata
Citrus microcarpa Citrus grandis
Mangifera indica Spondias purpurea
Pyrus malus Hibiscus esculentus
Ricinus communis Bixa orellana
Tithonia diversifolia Cosmos sp.
Oryza sativa Zea mays
Cocos nucifera Lycopersicon esculentum
III. ACTIVITY
A. Study carefully all the fruit specimens and try to match their types with the list here.
Types of Fruits
1. According to composition and origin
a. Simple fruit - a fruit that results from the ripening of a single ovary. b. Compound fruit – when the fruit develop from several ovaries. 1) Aggregate fruit – a fruit that develop from several ovaries that belong to a single flower and become crowded into a mass. These are joined together by a common receptacle. 2) Multiple or collective fruit – a fruit that is derived from the ovaries of several flowers that unite into a mass.
Example: cone – a multiple fruit consisting of overlapping appressed scales, each scal bearing one or two seeds on its surface. 3) Accessory fruit – fruit that develops from other parts of the flower other than the ovary.
Example: pome – a fruit in which most part develops from the receptacle.
2. According to texture
