Solution
The correct option is D Adipose tissue.
The correct option is D:
Explanation of the correct option:
- Blubber is a thick layer of fat beneath the skin of all marine mammals, commonly known as adipose tissue.
- Seals, whales, and walruses have blubber that covers their entire bodies except for their fins, flippers, and flukes.
- Adipose tissue also referred to as fat tissue or fatty tissue, is a connective tissue made up primarily of fat cells known as adipocytes.
- Adipocytes are fat-storing cells with enormous globules of fat called lipid droplets that are surrounded by a network of fibers.
Explanation of the incorrect option:
Option A:
- The areolar tissue in the skin connects the skin's outer layers to the muscles beneath (holds organs in place and attaches epithelial tissue to other underlying tissues).
- Areolar tissue can also be found in or near mucous membranes, blood vessels, nerves, and the body's organs.
- Areolar connective tissue is a form of connective tissue that links and surrounds the organs of the human body.
- This sort of tissue has two vital functions: it feeds the cells and acts as a cushion to protect the organs from various external stresses.
Option B:
- Chondrocytes are the specialized cells that make up cartilage.
- The chondrocytes extracellular matrix is made up of collagen, proteoglycan, and elastin fibers.
- Chondroblasts are a type of immature cells that secret the cartilage's extracellular matrix.
- Chondroblasts become chondrocytes when the matrix surrounds them.
Option C:
- Epithelial tissues are thin tissues that cover all of the body's exposed surfaces.
- They cover a variety of body surfaces, including the inner lining of the mouth, the digestive tract, secretory glands, and the lining of hollow organ sections such as the heart, lungs, eyes, and the urogenital tract.
Final answer: The type of tissue present in the blubber of whales is adipose tissue.
