DCCC BIO150 Lab Practical 2 Exam
2026 Questions and Answers
areolar connective tissue - Correct answer-a loose, mesh-like network with
sparsely arranged collagen fibers (staining pink) and thin elastic fibers (staining
purple) embedded in a substantial amount of ground substance, with various cell
types like fibroblasts, macrophages, and mast cells scattered throughout
adipose tissue - Correct answer-large, round cells called adipocytes, which are
mostly filled with a single large lipid droplet, pushing the nucleus to the periphery
of the cell
hyaline cartilage - Correct answer-a translucent matrix with sparsely distributed
rounded chondrocytes residing in small cavities called lacunae; the fine collagen
fibers within the matrix are often too small to be clearly visible
elastic cartilage - Correct answer-a solid matrix with dark-colored bundles of
elastic fibers

, fibrocartilage - Correct answer-matrix contains thick bundles of collagen fibers that
run in parallel beams between rows of chondrocytes; chondrocytes are smaller and
are found in round or oval lacunae
compact bone - Correct answer-closely packed osteons which consists of a central
canal called the central (haversian) canal, which is surrounded by concentric rings
(lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are
located in spaces called lacunae, canaliculi are small channels that radiate from the
lacunae to the central canal of the osteon
simple cuboidal epithelial tissue - Correct answer-single layer of cube shaped cells,
round nucleus in the middle of the cell
simple columnar epithelial tissue - Correct answer-consists of a single layer of cells
that are taller than they are wide, with an oval nucleus usually located towards the
basal region of the cell, goblet cells look like wine glasses
smooth muscle tissue - Correct answer-elongated, spindle-shaped cells with a
single, centrally located nucleus, lacking any visible striations, and often appearing
as a sheet of tightly packed cells
skeletal muscle tissue - Correct answer-long, cylindrical fibers with a distinct
"striated" or striped appearance due to alternating light and dark bands across the
muscle fiber
