Fruits have fructose for

Options

A. Attracting animals for seed dispersal
B. Fruit ripening
C. Maturation of seeds
D. Nourishment of embryo

Answer

**Step-by-Step Solution:**

1. **Understanding the Composition of Fruits:**
- Fruits contain natural sugars, primarily fructose and glucose. The proportions can vary, but many fruits have roughly equal parts of both sugars.

2. **Evaluating the Options:**
- The question asks for the purpose of fructose in fruits. The options provided are:
- a) Attracting animals for seed dispersal
- b) Fruit ripening
- c) Maturation of seeds
- d) Nourishment of embryo

3. **Analyzing Each Option:**
- **Option a: Attracting animals for seed dispersal**
- Fruits are designed to be eaten by animals, which helps in the dispersal of seeds. The sweetness from fructose makes fruits appealing to animals, encouraging them to consume the fruit and subsequently disperse the seeds.

- **Option b: Fruit ripening**
- Fruit ripening is primarily regulated by ethylene, not fructose. Therefore, this option is incorrect.

- **Option c: Maturation of seeds**
- The maturation of seeds is influenced by hormones like abscisic acid and gibberellins, not by fructose. Thus, this option is also incorrect.

- **Option d: Nourishment of embryo**
- The embryo receives nourishment from the endosperm of the seed, not directly from fructose in the fruit. Hence, this option is incorrect.

4. **Conclusion:**
- The correct answer is **a) Attracting animals for seed dispersal**. The presence of fructose in fruits serves to make them sweet and appealing, which aids in attracting animals that help in seed dispersal.
