Difference Between Simple and Complex Tissue

Ans: Primary difference between simple and complex tissue is that simple tissue is made up of only one type of cell whereas in the case of complex tissue it is formed of many types of cells. Simple tissue is homogeneous, whereas complex tissue is heterogeneous in nature. 

• Simple Tissues perform a variety of functions like protection, storage, and provide mechanical support.
• Complex tissues assist in the moving of organic material, water, and minerals throughout the plants.

Ans: There are two types of tissues – Simple and Complex Tissues. Simple Tissues are parts that are made up of a single type of cell and because of which all the cells perform similar functions. Complex tissues are also called Vascular tissues, they consist of more types of cells and work together on various functions.

Ans: The simple tissue in animals is called Epithelium, whereas these tissue in plants is called Epidermis. Parenchyma, chlorenchyma, aerenchyma, collenchyma, sclerenchyma and epidermis are different types of simple tissues.

Ans: Xylem is made out of dead cells, but parenchyma is the only living cell which is present in the xylem). Phloem is made out of living cells, but fibres are the only dead cells which are present in the phloem.

Ans: Complex tissue is heterogeneous. Simple Tissues include Phloem which has phloem fibres, phloem parenchyma, sieve tubes, companion cell and these are heterogeneous. However, Xylem is also a simple tissue which includes xylem vessels, xylem parenchyma, xylem fibres and tracheid and they are also heterogeneous.

Ans: These are heterogeneous which means they are made up of different types of cells. They occur only in the vascular region. Examples: Xylem and Phloem.

Ans: The three types of simple tissues are as follows:

• Parenchyma: It has thin-walled cells. They are usually found in stems and leaves. This tissue helps to provide mechanical support and protection. It also stores nutrients and water in stems and roots.
• Collenchyma: In this type of simple tissue, walls are unevenly thick. This Simple Tissue helps in providing softness and flexibility.
• Sclerenchyma: This helps in providing rigidity and mechanical strength as well. Mature Sclerenchyma cells are dead cells. There will be no spaces separating cells.

Ans: The similarities found in simple and complex tissues are as follows:

• Both simple and complex tissues provide support to the plant.
• We can find both types of tissues in plants.
• Both tissues will help in water conduction.
• Both types of tissues help in the translocation of food in plants.

Ans: The different types of complex tissues are as follows:

• Xylem: Xylem helps in the transportation of water and minerals from roots to all parts of the plant. They are located at the centre of the plant. These cells are attached end to end to produce long tubes.
• Phloem: Phloem helps in the transportation of food i.e., sugar and nutrients from leaves to all parts of the plant. They are located at the outer part of the plant-like bark.

Ans: The different types of parenchyma are as follows:

• Chlorenchyma: This substance aids in photosynthesis and has chlorophyll in it.
• Aerenchyma: This is the part of aquatic plants that has air cavities in it. It gives aquatic plants buoyancy. In anaerobic soil, they aid in the development of the anaerobic rhizosphere.

Ans: The different types of sclerenchyma are as follows:

• Fiber: The plant receives strength from their lengthy cells. They are present in the stem, roots, and vascular bundles of leaves and are frequently discovered in bundles or strands. Their primary habitats include patches, clumps, and clusters.
• Sclereids: Sclereids can be found in a variety of tissues, including the periderm, cortex, pith, xylem, and phloem. They can be found in many different plant components, such as the nut and seed coats. For instance, the granular texture of guavas and pears.
