Answer

To fill in the blanks in the given statements, let's analyze each part step by step:

I) **Genes of plants, bacteria, fungi, and animals have been changed by manipulations; therefore, these organisms are called ...A...**

- The correct term for organisms whose genetic material has been altered through manipulation is **genetically modified organisms (GMOs)**. This term encompasses all organisms that have undergone genetic modifications, whether through deletion, duplication, or other alterations.

**A = Genetically Modified Organisms (GMOs)**

---

II) **The organisms in which foreign genes have been introduced by genetic engineering are called ...B...**

- When foreign genes are introduced into an organism through genetic engineering, those organisms are specifically referred to as **transgenic organisms**. This term highlights that the organism contains genes from another species.

**B = Transgenic Organisms**

---

**The foreign genes change the host cell genetically; such genes are known as ...C...**

- The foreign genes that are introduced into the host organism are called **transgenes**. These are the actual genes that have been transferred and are responsible for the new traits exhibited by the transgenic organism.

**C = Transgenes**

---

**The production of transgenic organisms is called ...D...**

- The process of creating transgenic organisms through the introduction of transgenes is known as **transgenesis**. This term describes the entire process of gene transfer and the resulting genetic modification.

**D = Transgenesis**

---

III) **Bt cotton was first cultured to kill ...E...**

- Bt cotton is a genetically modified organism that has been engineered to produce a protein from the bacterium Bacillus thuringiensis (Bt) that is toxic to certain pests. The specific pest that Bt cotton is designed to kill is the **bollworm**.

**E = Bollworm**

### Summary of Answers:
- A = Genetically Modified Organisms (GMOs)
- B = Transgenic Organisms
- C = Transgenes
- D = Transgenesis
- E = Bollworm
