Given this definition, mosses carry out not have roots. ‘Vascular’ plants room those with root systems, mosses are ‘non-vascular’.
Instead, they have ‘rhizoids‘, small ‘hairlike’ structures whose main role is anchoring the plant to the ground, rock or bark.
What does ‘non-vascular’ mean?
‘Vascular’ plants have roots that transfer water come the plant and also food to and also from the roots and plant body. In addition, vascular plants have actually two types of tissue that assist this transport:
Xylem – a specialty water transferring cell used to move water upwards from root to remainder of plant.
Phloem – living tissue that transports essential compounds / food together ‘sap’ throughout a plant. Occasionally to the roots because that storage and at other times to the parts of the plant that require food because that growth.
Mosses are ‘non-vascular’ – having actually none of these structures.
Without the ability to transfer food and water from root – mosses have to absorb water and nutrients directly through their bodies.
The lack of interior transportation (or pipeworks) typical these plants carry out not grow an extremely tall. The also way they room soft and ‘springy’ – having no stems or wood.
Given this lack of root system it is no wonder that moss grow in moist environments with a the majority of water.

Rhizoids or Rhizomes?
Rhizomes are often used interchangeably for the ax rhizoids as soon as talking around moss.
But rhizoids are not the very same thing as rhizomes.
Rhizomes are found in ‘vascular’ plants and are in reality a component of the ‘stem’ the grows secret (primarily). They often store food and also produce roots.
A potato is an example of a thickened component of a rhizome – storing food greatly as starches. Moss rhizoids carry out not carry out this function.
So mosses have actually rhizoids, no rhizomes.
Do rhizoids absorb any water or nutrients?
Scientific studies present that an lot of absorb does occur through the rhizoids. So it is not entirely true to state the no absorption happens.
But, by comparison to the absorption through the rest of the moss body this is really small. The is clearly not the primary characteristics of the moss rhizoid.
In true vascular plants the roots perform the majority the the water and nutrient absorption. Only a small amount of water absorb happens with the leaves.
Capillary activity and Rhizoids
When part rhizoids are very closely wound with each other (in details moss species) castle can transport water using capillary action to the remainder of the plant.

This does typical that the water travels ‘outside’ and also along the plant in the direction of the tree body whereby it can be absorbed.
