OBJECTIVES: 1. 2. Define a fruit Say how many types of fruits are there 3. Name the types of fruits 4. Give examples of each type of fruit 5. Draw and label the parts of a dry and fleshy fruit 6. Discuss the functions of fruits
The parts of the flower that develops into the fruit and seed The ovary develops into the fruit and the ovule develops into the seed.
Definition of a fruit A fruit is a fully grown fertilized ovary containing the fully developed fertilized ovules , the seed.
INTRODUCTION:
Types of fruits The six types of fruits are: 1. dry fruits 2. juicy fruits 3. dehiscent fruit 4. indehiscent fruit 5. false fruit 6. multiple fruit
Dry fruits – when the fruit ripens the fruits become hard and dry. They are not easily damaged and can be stored for a long time after harvesting
Examples of Dry Fruits Nuts coconut
Fleshy fruits – these are juicy, succulent and non- splitting. They are easily damaged and cannot be stored for long period after harvesting
Juicy fruit
Dehiscent Fruits These are fruits which split open at maturity (when they are ripe). This opening is by natural means to shed the contained seeds. (splitting)
Legumes Ackee
Indehiscent Fruit These fruits do not split open when mature to shed their seeds
Indehiscent Fruits
False Fruit The cashew is described as a false fruit. The true fruit is the nut and the fleshy juicy part is the swollen receptacle
Multiple Fruit The pineapple is an example of a multiple fruit. It is made up of a number of carpel fused together to give thick juicy flesh that we use in our salad and fruit cocktail.

Functions of fruits 1. Food storage – fruits store food made by the plant in the cotyledons of their seed. This food is used during germination. 2. Seed dispersal- plants rely on animals to feed on the fruits, and to carry the seed some distance away from the parent plant. Some of these seeds then fall on the ground and germinate to produce new plant. Dispersal of plant is important because if young plants are scattered over a large area they will compete less with each other for light and water.
