Are the cells specialized for different functions?

Answer 1

Yes, certain types of plant cells are specialized for different functions.

This is the same in all type of cell families (animal...)

Some examples of this are:

1. Parenchyma Cells, which are the most general of plant cells. They consist of thin flexible cell walls. They contain a large central vacuole and can carry out most of the metabolic functions of the plant. Mesophyll cells of the leaf are parenchyma cells. The fleshy tissue of most fruits also contain parenchyma.

2. Collenchyma Cells, which have a much thicker primary wall than the parenchyma cell. Grouped in strands or cylinders, they support young plants.

3. Sclerenchyma Cell, which function in support of the plant. They contain a thick secondary wall containing lignin. Basically, these cells function best when dead.

4. Tracheids, which are water conducting elements. These cells are dead and are found along with vessel elements, making up the plants xylem.

5. Sieve-tubes, which function in carrying food throughout the plant. They are kept alive and nourished by companion cells. These are found in the plants phloem.

Answer 2

Cells are specialized to carry out a function due to their specialized structure, this special structure of the cells helps them to carry out the function.

For example -

Leaf cells have continuous layer of chloroplasts packed together for efficient absorption of sunlight for photosynthesis.

Root hair cells are long, have a large surface area and extend into the soil to absorb water and mineral ions from the soil effectively.

Answer 3

Yes, and each type of specialized function is represented by a different type of Tissue.

Answer 4

Yes, these specialized Cells conglomerate to form Tissues.
