Cycas stems shows

• A. Porous wood
• B. Manoxylic wood
• C. Pycnoxylic wood
• D. Ring porous wood

Cycas stems are characterized by a specific type of wood known as manoxylic wood. This type of wood is notable for its soft and spongy texture, which is quite different from the dense and hard woods found in many other plants.

Key Features of Manoxylic Wood

• Soft Texture: Manoxylic wood is less dense, making it lighter and easier to work with.
• Water Storage: This wood can store water, which is beneficial for the plant in arid environments.
• Growth Form: It supports the unique growth form of Cycas, allowing it to thrive in various conditions.

Comparison with Other Wood Types

Unlike pycnoxylic wood, which is dense and hard, or ring porous wood, which has distinct growth rings, manoxylic wood serves a different ecological purpose. It is primarily adapted for survival in specific habitats.

In summary, the correct answer to the question about Cycas stems is B. Manoxylic wood.
