Answer 2

Answer:

Explanation:

Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage. The stretchy properties of the strands of celery are due to collenchyma tissue. Collenchyma tissue is found immediately under the epidermis, young stems, petioles, and leaf veins. Also, it has been seen in avocado fruit hypodermis. Collenchyma cells may or may not contain a few chloroplasts, and may perform photosynthesis and store food.
