Which of the following tissue is rich in starch and sugar?

Options

A. Wood
B. Bark
C. Cambium
D. Periderm

Answer

To determine which tissue is rich in starch and sugar, we will analyze the options provided and identify the correct tissue type step by step.

### Step 1: Understand the question
The question asks which tissue is rich in starch and sugar. We need to identify the type of tissue that contains a high concentration of these carbohydrates.

### Step 2: Analyze the options
Let's evaluate the different types of tissues mentioned in the video transcript:

- **Option A: Wood**
- Wood consists of xylem and phloem. While sapwood (a part of wood) is live and conductive, it is primarily involved in water transport and does not store significant amounts of starch and sugar.

- **Option B: Bark**
- Bark includes the outer layer of the plant, which is mainly composed of cork (phellem) and phloem. Phloem is involved in the transport of sugars, but it is not specifically rich in starch.

- **Option C: Cambium**
- Cambium is a layer of actively dividing cells (meristematic tissue). These cells are live and can store both starch and sugar, making them a potential candidate for the answer.

- **Option D: Periderm**
- Periderm includes cork cambium (phellogen) and cork (phellem). This tissue is primarily protective and consists of dead cells, which do not store starch or sugar.

### Step 3: Identify the correct answer
From the analysis, we find that the cambium (Option C) is the tissue that is rich in both starch and sugar due to its live, actively dividing cells.

### Conclusion
The tissue that is rich in starch and sugar is **C: Cambium**.
