"...Plant cells do not really have as big of a need as animal cells for movement. Because of this, plant cells have smaller, non-complex systems for movement."

Previously, we've looked at the structure and function of animal tissue. We now turn our attention to plant cells and tissues.

As a plant matures, its cells become specialized. There are a number of important specialized plant cell types.

Plant Cell Types

Some examples of specialized plant cells include:

Parenchyma Cells

Parenchyma cells are usually depicted as the "typical" plant cell because they are not very specialized. These cells synthesize and store organic products in the plant. Most of the plant's metabolism takes place in these cells.

Collenchyma Cells

Collenchyma cells have a support function in plants, particularly in young plants. These cells help to support plants while not restraining growth due to their lack of secondary walls and the absence of a hardening agent in their primary walls.

Sclerenchyma Cells

Sclerenchyma cells also have a support function in plants but unlike collenchyma cells, they have a hardening agent and are much more rigid.

Water Conducting Cells

Water conducting cells of xylem are usually of two types, tracheids and vessel elements. Both allow water to flow to different parts of a plant.

Sieve Tube Members

Sieve tube members of phloem conduct organic nutrients such as sugar throughout the plant.
