Question

What is the difference between primary and secondary xylem?

Answer 1

Hint: The vascular tissue xylem is in charge of transporting water and nutrients from the roots to the shoots and leaves. A xylem is characterised as a primary or secondary xylem depending on its stage and growth.
Complex tissues are made up of cells of several types that operate together as a unit. Xylem and phloem are complex tissues found in plants.

Complete answer:

PRIMARY XYLEM	SECONDARY XYLEM
It is made up of the apical meristem's procambium.	The lateral meristem, also known as the vascular cambium, produces secondary xylem.
All vascular plants have it in their major plant bodies.	Only during secondary growth does secondary xylem occur.
All types of organs contain primary xylem.	It only affects perennial dicots and gymnosperms' stems and roots.
It happens in the centre.	It is found on the principal xylem's outer side.
Patches of primary xylem can be found.	Secondary xylem takes the shape of a cylinder.
The xylem is split into two sections: protoxylem and meta-xylem.	Such a differentiation does not exist.
There is no radial system.	A radial system of xylem rays runs through it.
There are no annual rings.	It could have annual rings on it.
Sapwood and heartwood are not distinguished.	In large woody trees, sapwood and heartwood are distinguished.
Fibres are few or non-existent.	Fibres are plentiful in most cases.
The tracheids and vessels are lengthy and thin-walled in comparison.	The tracheids and vessels are shorter and have thicker walls than the rest of the body.
Tracheary components can develop a variety of thickenings.	Pitted thickenings are most commonly found in the tracheary components.
In most cases, tyloses are not present.	The growth of tyloses blocks the vessels and tracheids of older xylem cells.

Note:
Both Primary and Secondary Xylem comprise vessels, xylem fibres, and xylem parenchyma, among other things.
Both transport water from the root to the plant's higher parts.
Both of these tissues are distinct from the cambium.
