Which of the following is not a characteristic of land plants?

• A. Lack of a vascular system
• B. Photosynthesis
• C. Chloroplasts
• D. Cell walls made of cellulose

Answer: (A)

Verified step by step guidance

1. Begin by understanding the characteristics of land plants. Land plants, also known as embryophytes, typically have certain features that distinguish them from other organisms.
2. Consider the role of photosynthesis in land plants. Photosynthesis is a process by which plants convert light energy into chemical energy, using chlorophyll in chloroplasts. This is a fundamental characteristic of land plants.
3. Examine the presence of chloroplasts. Chloroplasts are organelles found in plant cells that facilitate photosynthesis. They are a defining feature of land plants.
4. Analyze the composition of cell walls in land plants. Land plants have cell walls made of cellulose, which provides structural support and protection.
5. Evaluate the vascular system. A vascular system, consisting of xylem and phloem, is present in most land plants to transport water, nutrients, and sugars. However, some primitive land plants, like mosses, lack a vascular system, which is a key point in identifying the characteristic that is not common to all land plants.
