Which of the following are incorrect?
A. Plant seeds develop in ovule which itself usually becomes the fruit.
B. Plants produce flowers in order to make seeds, so that their species can propagate,
C. Just as roots of some plants store food, they may also have nodes, internodes and buds.
D. For photosynthesis, leaves take in carbon dioxide and water from soil to release oxygen in air.

Options

A. (a) A and C
B. (b) B and D
C. (c)C and D
D. (d)A, C and D

Answer

To determine which statements are incorrect, let's analyze each statement one by one:

### Step 1: Analyze Statement A
**Statement A:** "Plant seeds develop in ovule which itself usually becomes the fruit."

- **Analysis:** This statement is incorrect. In plant reproduction, the ovule develops into the seed, not the other way around. Additionally, the ovary of the flower develops into the fruit, not the ovule.

### Step 2: Analyze Statement B
**Statement B:** "Plants produce flowers in order to make seeds, so that their species can propagate."

- **Analysis:** This statement is correct. Flowers are indeed produced by plants for the purpose of reproduction, which includes the formation of seeds that help in the propagation of the species.

### Step 3: Analyze Statement C
**Statement C:** "Just as roots of some plants store food, they may also have nodes, internodes and buds."

- **Analysis:** This statement is incorrect. While some roots can store food, they do not have nodes, internodes, or buds. These structures are typically found on stems, not roots.

### Step 4: Analyze Statement D
**Statement D:** "For photosynthesis, leaves take in carbon dioxide and water from soil to release oxygen in air."

- **Analysis:** This statement is incorrect. While leaves do take in carbon dioxide and water for photosynthesis, carbon dioxide is obtained from the air, not from the soil. Water is absorbed from the soil, but carbon dioxide comes from the atmosphere.

### Conclusion
Based on the analysis:
- **Incorrect Statements:** A, C, and D
- **Correct Statement:** B

Thus, the answer to the question is that statements A, C, and D are incorrect.
