Read the following features given below:
I. Cells are thick at corner due to the deposition of cellulose, hemicelluloses and pectin.
II. Cells may contain chloroplast and get assimilated.
III. Intercellular spaces are absent.
IV. Provide mechanical support to growing parts of the plant such as young stem and petiole of the leaf.
These features describe which of the following?

Options

A. Collenchyma
B. Parenchyma
C. Xylem
D. Sclerenchyma

Answer

To solve the question, we need to analyze the features provided and determine which plant tissue they describe. Let's break down each feature step by step:

### Step 1: Analyze Feature I
**Feature I:** "Cells are thick at corners due to the deposition of cellulose, hemicelluloses and pectin."

- This feature indicates that the cells have thickened corners, which is characteristic of collenchyma tissue. In collenchyma, the thickening occurs at the corners due to the deposition of these substances.

**Hint for Step 1:** Look for tissues with thickened cell walls, especially at the corners.

### Step 2: Analyze Feature II
**Feature II:** "Cells may contain chloroplast and get assimilated."

- This feature suggests that the cells can perform photosynthesis, which is a function of collenchyma cells. They can contain chloroplasts, allowing them to assimilate nutrients.

**Hint for Step 2:** Consider which plant tissues are involved in photosynthesis.

### Step 3: Analyze Feature III
**Feature III:** "Intercellular spaces are absent."

- This feature indicates that there are no spaces between the cells, which is again a characteristic of collenchyma tissue. The cells are tightly packed together without intercellular spaces.

**Hint for Step 3:** Think about the arrangement of cells in the tissue. Tightly packed cells usually indicate a specific function.

### Step 4: Analyze Feature IV
**Feature IV:** "Provide mechanical support to growing parts of the plant such as young stem and petiole of the leaf."

- This feature describes the primary function of collenchyma, which is to provide structural support to young, growing parts of the plant.

**Hint for Step 4:** Identify tissues that provide support, especially in young plant structures.

### Conclusion
Based on the analysis of all four features, they all point towards **collenchyma tissue**. Therefore, the correct answer to the question is:

**Answer: Collenchyma**
