DCCC BIO 150 LAB PRACTICAL 2 FINAL PAPER
2026 QUESTIONS WITH ANSWERS GRADED
A+
◉ adipose tissue. 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. 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. Answer: a solid matrix with dark-colored bundles of
elastic fibers
◉ fibrocartilage. 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. 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. Answer: single layer of cube shaped
cells, round nucleus in the middle of the cell
◉ simple columnar epithelial tissue. 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. 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. Answer: long, cylindrical fibers with a distinct
"striated" or striped appearance due to alternating light and dark bands
across the muscle fiber
◉ cardiac muscle tissue. Answer: striated tissues that's cells are joined at
their ends by intercalated discs, which are thin lines that appear slightly
darker than the surrounding muscle.
, ◉ stratified squamous epithelial tissue. Answer: multiple layers of
flattened, scale-like cells stacked on top of each other, with the basal
(bottom) layer containing cuboidal cells which gradually transition into
flatter squamous cells; the nuclei of the cells become smaller and less
visible as they approach the apical surface
◉ simple squamous epithelial tissue. Answer: a single, thin layer of flat,
scale-like cells with centrally located, flattened nuclei, often resembling
a "pavement" appearance, where the cells are tightly packed together
and appear almost like tiles
◉ pseudostratified columnar epithelial tissue. Answer: a single layer of
elongated, column-shaped cells with nuclei positioned at different levels,
giving the illusion of multiple layers even though all cells are attached to
the basement membrane
◉ orbicularis oculi. Answer: around the eye
◉ orbicularis oris. Answer: around lips
◉ platysma. Answer: superficial neck muscle
◉ scalene. Answer: deepest lateral neck muscles, 3 of them,
◉ sternocleidomastoid. Answer: middle of the neck, deep
