A scientist is studying a newly discovered plant species. Microscopic analysis of the stem reveals living cells with unevenly thickened cell walls, primarily composed of pectin and hemicellulose, providing flexible support. These cells lack lignin and are found in patches beneath the epidermis. Which tissue type is being observed?
Collenchyma
Sclerenchyma
Parenchyma
Xylem

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.
