The key difference between simple permanent tissue and complex permanent tissue is thatsimple permanent tissue has only one type of cells while complex permanent tissue has different types of cells which are structurally and functionally different.另一个主要区别简单永久tissue and complex permanent tissue is that the simple permanent tissue is present in all parts of the plant whereas the complex permanent tissue is present mostly in vascular tissue.
Plants contain different types of tissues. Based on the ability to their divide, there are two types of tissues namelymeristematic tissueand permanent tissue. The meristematic tissue has undifferentiated cells which have the capability to divide. Permanent tissue originates from the meristematic tissue. Furthermore, the permanent tissue has differentiated cells which are not capable of dividing. There are three types of permanent tissues, and simple permanent tissue and complex permanent tissue are two types among them.

What is Simple Permanent Tissue?
The simple permanent tissue is a type of plant tissue which has a single type of cells. All its cells are structurally and functionally similar. They are available in almost all parts of a plant. There are three main types of this tissue; parenchyma,collenchymas, and sclerenchyma.
Parenchyma cells are the simplest form of plant cells. It is the commonest form present in pith, cortex, pericycle, epidermis, leaves, fruits, roots, etc. Parenchyma cells show little specialization. Collenchyma cells are the second type, which is stronger and elastic. They are elongated cells. Sclerenchyma cells are much elongated and lignified. Hence they are the cells that provide mechanical support to the plant. Due to secondary thickening, they are dead cells, unlike parenchyma and collenchymas, which are live cells.
什么是复杂的永久性组织?
复杂的永久性组织是具有不同类型细胞的植物组织。这些细胞在组织中执行不同的功能。但是,所有细胞都是分化的细胞并专门化的。木质部和韧皮部are the two major types of complex permanent tissues in plants.
Xylem conducts water and minerals throughout the plant. It consists of four cell types: xylem vessels, tracheids, xylem fibers, and xylem parenchyma. Phloem tissue transports nutrients from leaves to other plant parts. It is made up of sieve cells, companion cells, phloem fibers, and phloem parenchyma.
What are the Similarities Between Simple Permanent Tissue and Complex Permanent Tissue?
- 简单的永久性组织和复杂的永久性组织是两种类型的植物组织。
- Both have a collection of cells.
- These two tissue types perform important functions in plants.
- They contain differentiated cells.
- Both originate from the meristematic tissue.
What is the Difference Between Simple Permanent Tissue and Complex Permanent Tissue?
简单的永久性组织由一种类型的细胞组成。另一方面,复杂的永久性组织具有不同类型的细胞,这些细胞执行多种功能。实质,康塞间和硬化菌是简单的永久性组织,而木质部和韧皮部是复杂的永久性组织。此外,简单的永久性组织存在于植物的所有部分,而复杂的永久性组织主要存在于血管组织中。
概括– Simple Permanent Tissue vs Complex Permanent Tissue
永久性组织由分化细胞组成。永久性组织有两种主要类型。它们是简单的永久性组织和复杂的永久性组织。简单的永久组织和复杂的永久组织之间的主要区别是它们所包含的细胞类型。
