Identify the type of plant tissue being represented by the set of statements given below
I.Their cells are isodiametric (they may be spherical,oval round etc)
II.Their cell walls are thin and made up of cellulose
III.They may either be closely packed or have small intercellular spaces
IV.They perform functions like photosynthesis ,storage,secretion etc.

Options

A. sclerenchyma
B. parenchyma
C. collenchyma
D. xylem

Answer

To identify the type of plant tissue based on the given statements, we can analyze each statement step by step:

### Step 1: Analyze the first statement
**Statement I:** The cells are isodiametric (they may be spherical, oval, round, etc.).
- **Explanation:** Isodiametric cells are those that have equal dimensions in all directions. This characteristic is typical of parenchyma cells, which can take various shapes.

**Hint:** Look for tissues with cells that can have various shapes but are generally similar in size.

### Step 2: Analyze the second statement
**Statement II:** Their cell walls are thin and made up of cellulose.
- **Explanation:** Parenchyma cells have thin cell walls primarily composed of cellulose, which is a defining feature of this tissue type.

**Hint:** Consider the composition of cell walls in plant tissues; thin walls suggest a specific type of tissue.

### Step 3: Analyze the third statement
**Statement III:** They may either be closely packed or have small intercellular spaces.
- **Explanation:** Parenchyma cells can be found in both tightly packed arrangements or with small spaces between them, allowing for gas exchange and storage.

**Hint:** Think about how the arrangement of cells can affect their function, especially in terms of space.

### Step 4: Analyze the fourth statement
**Statement IV:** They perform functions like photosynthesis, storage, secretion, etc.
- **Explanation:** Parenchyma cells are multifunctional; they are involved in photosynthesis (especially in green parenchyma), storage of nutrients, and secretion of substances.

**Hint:** Identify the functions of the tissue; multifunctionality often indicates a specific type of tissue.

### Conclusion:
Based on the analysis of all four statements, the type of plant tissue being described is **Parenchyma**.

### Final Answer:
**The answer is Parenchyma cells.**
