Majority of plant viruses are transmitted by

Options

A. insects
B. birds
C. insects
D. cattles

Answer

To answer the question "Majority of plant viruses are transmitted by," we will follow these steps:

### Step 1: Understand the question
The question is asking about the primary mode of transmission for plant viruses. We need to identify the organisms that are responsible for spreading these viruses among plants.

**Hint:** Focus on the common vectors known for transmitting diseases in plants.

### Step 2: Identify potential carriers
Consider the different organisms that could potentially transmit plant viruses. Common candidates include insects, birds, and mammals (like cattle).

**Hint:** Think about which of these organisms interact with plants frequently and could carry viruses.

### Step 3: Analyze the role of insects
Insects are known to be small and have a simple genetic structure, which allows viruses to easily infect them. They can carry viruses within their bodies and transmit them while feeding on plants or through other interactions.

**Hint:** Recall how insects interact with plants and their role in pollination and feeding.

### Step 4: Consider the role of birds and mammals
Birds and mammals, such as cattle, are larger organisms. While they may interact with plants, they typically do not serve as effective carriers for plant viruses. Instead, they may act as hosts where the virus can complete its life cycle but do not facilitate the transmission to other plants.

**Hint:** Think about the life cycle of viruses and how they depend on their vectors for transmission.

### Step 5: Conclude the answer
Based on the analysis, the majority of plant viruses are transmitted by insects. They are the primary vectors due to their size, behavior, and interaction with plants.

**Final Answer:** Majority of plant viruses are transmitted by insects.
