Cell Structure Of Hardwood And Softwood

This means the cells are the nutrient conduits.

Cell structure of hardwood and softwood.

Wood is soft and light with a fine texture. Something commonly called cranky grain. 2 wood is hard and heavy with a rough texture. The cell structure being more complex make it harder to work with.

Softwoods are simpler and more homogeneous in structure than hardwoods. Slow growth unlike softwood hardwood forests take longer to replenish due to the tree s slower growth rate. 3 wood fibres present. Cellular details of softwood and hardwood biodiversity of dead wood 2016 kurt fagerstedt water and cells in trees c.

There are differences between the physical structures of hardwoods and softwoods. Some softwoods also have axial parenchyma cells but these are never as abundant as in hardwoods. Hardwood softwood 1 hardwood is the wood of dicot angiosperms. Longitudinal tracheids are cells that give the tree support and conduct water.

On page 82 of textbook. Softwoods which come from conifers such as fir pine and cedar have a simple cellular structure with 90 95 of the cells being longitudinal tracheids. Hardwood is hard and heavy with a rough texture whereas softwood is soft and light with a fine texture. Density most softwood have a comparatively lower density than most hardwoods.

This is usually visible at both microscopic level and at the surface hardwoods tend to have broad leaves while softwoods tend to have needles and cones. Nonetheless even though hardwood parenchyma cells can form much more complex and telling arrangements softwood parenchyma still have a limited use in identification. 80 95 of growing tissues is water sapwood pintapuu water transport important 50 75 water. Hard to work with due to its density hardwood tends to be a lot harder to work with during construction.

Fibres and vessel elements are absent. Hardwood structure hardwood xylem wood is composed of at least 4 major kinds of cells. Softwood is the wood of gymnosperms. Each of which may constitute 15 or more of the volume see table 5 1.

Hardwoods contain vessels softwoods do not. The actual cells in the softwood species have the same function as the vessels in hardwoods. The greater bulk of the axial cell system is made up of tracheids which function both in water conduction and support figs. The differences between hardwoods and softwoods come from the difference in their cellular structure.
