Question

The chloroplasts containing simple tissues showing thickening at the corners with cellulose, hemicellulose and pectin is_______.

Answer 1

Collenchyma:

1. A supporting tissue called collenchyma is made up of roughly elongated live cells with inconsistently thickened, nonlignified main walls.
2. It is in areas where stems and leaves are undergoing basic growth.
3. Elongated cells with sporadic thickening, usually at the corners, are found in collenchyma tissue.
4. The sturdy formation of plant cell walls is greatly aided by cellulose, a hard, fibrous, and water-insoluble polysaccharide.
5. The plant cell wall contains hemicellulose, a branching polymer of pentose and hexose sugars.
6. Plants' cell walls include pectin, which is made up of neutral sugar side chains attached to an acidic sugar backbone.
7. They only have a thick main cell wall consisting of pectin and cellulose.
8. They offer assistance and a framework.
9. The majority of plant tissues are made up of parenchyma and collenchyma, two types of plant tissues.
10. The collenchyma's main purposes are to shield the plant from mechanical harm, support the vascular tissue, and act as a sheath to control water flow.

Final answer: The chloroplasts containing simple tissues showing thickening at the corners with cellulose, hemicellulose, and pectin are collenchyma.
