column
Definition
A column is a vertical structure that supports weight. It is a common feature in architecture and engineering. Columns are often used to support roofs, bridges, and other structures.
There are many different types of columns. Some of the most common types include:
- Doric columns: Doric columns are the simplest type of column. They are characterised by their plain shafts and capitals.
- Ionic columns: Ionic columns are more ornate than Doric columns. They are characterised by their spiral flutings and capitals with volutes.
- Corinthian columns: Corinthian columns are the most ornate type of column. They are characterised by their elaborate capitals with acanthus leaves.
Columns are made from a variety of materials, including stone, concrete, and metal. The type of material used depends on the application. For example, stone columns are often used in classical architecture, while concrete columns are often used in modern architecture.
Columns are an important part of structural engineering. They help to distribute weight and to resist forces such as wind and earthquakes. Columns are essential for the safety of many structures.

AQA Science Exam Question and Answer
Question:
What is the function of a column in a plant?
Answer:
A column in a plant is a structure that supports the weight of the plant and helps to transport water and nutrients up from the roots. Columns are typically made of xylem, which is a type of vascular tissue that transports water and nutrients.
The function of a column in a plant can be summarised as follows:
Support: Columns help to support the weight of the plant, especially tall trees.
Transport: Columns transport water and nutrients up from the roots to the leaves.
Stability: Columns help to stabilise the plant and prevent it from toppling over.
Columns are an important part of plant structure and function. They help to keep plants upright and transport water and nutrients throughout the plant.
