Non-green plants like mushroom can't make their own food because

Options

A. they are too small
B. they lack chlorophyll
C. they lack photo-tropism
D. they lack roots to suck water

Explanation

### Step-by-Step Solution:

1. **Understanding Non-Green Plants**: Non-green plants, such as mushrooms, are classified as fungi. Unlike green plants, they do not have chlorophyll, which is essential for photosynthesis.

**Hint**: Remember that chlorophyll is the pigment responsible for the green color in plants and is crucial for photosynthesis.

2. **Photosynthesis Process**: Photosynthesis is the process by which green plants convert light energy into chemical energy, using chlorophyll to absorb sunlight and convert carbon dioxide and water into glucose and oxygen.

**Hint**: Think about the role of sunlight and chlorophyll in the food-making process of green plants.

3. **Absence of Chlorophyll**: Since mushrooms lack chlorophyll, they cannot perform photosynthesis. This means they cannot produce their own food like green plants do.

**Hint**: Consider what happens to a plant that cannot perform photosynthesis and how it affects its ability to produce food.

4. **Nutritional Dependency**: Instead of making their own food, mushrooms obtain nutrients by decomposing organic matter. They are classified as saprophytes because they feed on dead or decaying material.

**Hint**: Reflect on how different organisms obtain their food and the role of decomposers in ecosystems.

5. **Evaluating the Options**: The question provides several options regarding why mushrooms cannot make their own food. The correct answer is that they lack chlorophyll.

**Hint**: When answering multiple-choice questions, eliminate the options that are clearly incorrect before selecting the best answer.

### Final Answer:
Non-green plants like mushrooms cannot make their own food because they lack chlorophyll.
