Question

What is surcose what is the difference between xylem and pholem.

Answer 1

Sucrose is a common, naturally occurring carbohydrate found in many plants and plant parts. Saccharose is an obsolete name for sugars in general, especially sucrose.

Main Difference: Xylem Phloem are the vascular tissues that transport the food, minerals and water within the plant. Xylem transport the water and minerals whilePhloem transport food and nutrients. The movements in Xylem is unidirectional from roots to aerial parts while the movements in Phloem are bidirectional.

Answer 2

Sucrose is a type of sugar that is present in almost everything we eat. It is a natural compound and one that gives us valuable energy, but it can be harmful when over-consumed.

XYLEM

1. conducts water or sap.

2.  provides mechanical strength.

3. usually found deep in the plant.

4. In older plants, xylem often constitutes bulk of the plant body.

5. tracheary cells are dead.

6. Xylem is made up of three types of dead cells (vessels, tracheids, xylem fibres).

7. There are one type of living cells (xylem parenchyma).

8. The conducting cells have lignin thickening in the wall.

9. Conducting elements are of two types, vessels and tracheids.

10. Tracheary elements have different types of wall thickenings.

11. Vessels are devoid of septa.

PHLOEM 

1.conducts organic food.

2.  no mechanical function.

3.  usually situated towards the outer side of the plant.

4. always forms a small part of the plant body.

5. conducting cells are living.

6.  contains only one type of dead cells (phloem fibres).

7. There are three types of living cells (sieve tube cells, companion cells and phloem parenchyma).

8. Wall of the sieve tube does not possess lignin.

9. Conducting elements are of one type, sieve tubes.

10. Wall thickenings are absent in the conducting channels.

11. Sieve tubes have bulging and porous septa.
