Which of the following are simple tissues

Options

A. (a) Parenchyma, xylem, and phloem
B. (b) Parenchyma, collenchyma, and sclerenchyma
C. (c) Parenchyma, xylem, and collenchyma
D. (d) Parenchyma, xylem, and sclerenchyma

Answer

To determine which of the following are simple tissues, we need to understand the characteristics of simple tissues compared to complex tissues in plants. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Understand the Definition of Simple Tissues**:
- Simple tissues are made up of only one type of cell. This means all cells in a simple tissue perform the same function.

2. **Identify Types of Simple Tissues**:
- The main types of simple tissues in plants are:
- **Parenchyma**: These cells are involved in storage, photosynthesis, and tissue repair.
- **Collenchyma**: These cells provide support and flexibility to the plant.
- **Sclerenchyma**: These cells provide strength and protection, often having thickened cell walls.

3. **Understand the Definition of Complex Tissues**:
- Complex tissues are made up of more than one type of cell and perform different functions. The primary examples of complex tissues are:
- **Xylem**: Responsible for the transport of water and minerals.
- **Phloem**: Responsible for the transport of food.

4. **Analyze the Options Given**:
- If the options provided include parenchyma, collenchyma, and sclerenchyma, these are all examples of simple tissues.
- If the options include xylem and phloem, these are examples of complex tissues.

5. **Select the Correct Answer**:
- Based on the definitions and examples, the correct answer to the question "Which of the following are simple tissues?" is the option that lists parenchyma, collenchyma, and sclerenchyma.

### Final Answer:
- The correct option is **B: Parenchyma, Collenchyma, and Sclerenchyma**.
