• Sclerenchyma tissue has cells that have very thick lignified cell walls and are dead at maturity.

• The primary functions of sclerenchyma are support and protection.

• Some sclerenchyma cells are elongated, while other types are cubical or highly branched.

• Elongated sclerenchyma cells are called fibres and provide strength and support to plant parts. Plants fibres have been used extensively by people to make twine, rope and cloth.

•Collenchyma tissues are mainly found under the epidermis in stems in the large veins of leaves.

• The cells are composed of living, elongated cells running parallel to the length of organs that it is found in (up the side of the stem)

• Collenchyma cells have thick cellulose cell walls which are thickened at the corners.

• Intercellular air spaces are absent or very small.

• The cells contain living protoplasm (cytoplasm and nucleus) and they sometimes contain chloroplasts.

•Cells in parenchyma tissue are thin walled and are often block-shaped.

•Parenchyma cells remain alive at maturity and are abundant in roots, stems, leaves and fruit.

•The primary functions of parenchyma tissue are photosynthesis in leaves and storage of food as starch granules.

•You would expect such tissues to have many chloroplasts and/or amyloplasts

What is the structural difference between parenchyma and collenchyma?

The cell walls of parenchyma cells remain uniformly thin all along. In collenchyma cell walls at the corners get suberized and become thick to provide more regidity and strength to this tissue.

What is difference between collenchyma parenchyma and sclerenchyma?

Parenchymatous cells have thin cell wall, collenchymatous cells are suberized at the corners whereas sclerenchymatous cells are lignified.


What is the difference between parenchyma and collenchyma?

PARENCHYMA: 1) the tissue consists of thin-walled living cells. 2) it is distributed in almost all the parts of the plant body . 3) the living cells of parenchyma assimilate and store food .They also store waste products. 4) It contain dense cytoplasm. 5) Intercellular spaces may or may not be present. COLLENCHYMA: 1)the tissue consists of cells having localized thickening in their cell walls 2)it occurs mostly in the aerial parts of the plants restricted to the other layers 3)collenchyma is the chief mechanical tissue of the young parts of the plant particularly in the young dicotyledonous stems. in parenchyma cells are thin walled having intercellular spaces.and in collenchyma cells are thick walled having the absence of intercellular spaces. 4) It contain cellulose and pectin. 5) Intercellular spaces are totally absent. 6) Collenchyma is present in peripheral regions.


What is the difference between aerenchyma and chlorenchyma?

Chrolenchyma 1) In leaves and tender stems, parenchyma cells may contain chloroplast and in such case a parenchyma is called chlorenchyma. Aerenchyma 1) In aquatic plants, fairly large air cavities are present between the parenchyma cells; such a parenchyma is called aerenchyma.

Function of phloem parenchyma?

The parenchyma cells in between the sieve tubes of the phloem, and functions primarily for food storage.


What are the basic function of parenchyma tissue?

The basic function of the parenchyma tissue is to facilitate the transport of the small molecules between them.


What are differences between collenchyma and sclerenchyma?

collenchyma helps in making food and sclerenchyma gives mechanical support to plant body Edited answer: Collenchyma cells are thick at the corners whereas sclerenchyma cells are lignified all around. Both serve as mechanical tissue.


What is the difference in between xylem and phloem?

The difference between xylem and phloem is functional as well as structural. 1. xylem is used for conduction of water and minerals whereas phloem is used for conduction of prepared organic food material. 2. Xylem consists of trachieds, vessels (only in angiosperms) and xylem parenchyma, whereas phloem consists of sieve tubes, companion cells (only in angiosperms) and phloem parenchyma.


How can you differentiate between parenchyma and chlorenchyma?

Parenchyma is the primary tissue of higher plants. Its cells are thin-walled and are capable of cell division, even when mature. Chlorenchyma is a type of parenchyma that contains chloroplasts, It is found in leaves, where photosynthesis occurs..


What is the diffference between xylem and phloem?

Xylem contains Vessels, trachieds and xylem parenchyma Phloem consists of sieve tubes, companion cells and phloem parenchyma
