Yes, wood expands in cold weather as the cells grow. When these cells grow, sap travels from leaves and roots within the tree inside lengthy tube structures. As wood cells grow, they make long tube-like structures for sap to travel to and from the plant's leaves and roots. This can also occur with excessive heat. Dry weather has the opposite effect on the cells as the wood will shrink with excessively dry humidity.

How does wood expand in heat and what impact does this have on its structure and properties?

When wood is heated, the molecules within it gain energy and move more, causing the wood to expand. This expansion can lead to changes in the structure and properties of the wood, such as warping, cracking, or weakening of the material.
