Which statement BEST describes the relationship between collenchyma and sclerenchyma?
Both are composed of living cells at maturity.
Both have evenly thickened cell walls.
Both contain lignin in their cell walls.
Both provide structural support, but collenchyma provides flexible support in growing regions while sclerenchyma provides rigid support in mature regions.

Collenchyma cells often contain chloroplasts. What is the primary function of these chloroplasts in collenchyma tissue?
Photosynthesis, contributing to the plant's energy production.
Storage of starch and other carbohydrates.
Providing structural support to the cell.
Synthesis of pigments for coloration.
