The correct answer and explanation is:
It seems you need help with a review sheet that includes questions related to adipose tissue, smooth muscle tissue, and the vacuole containing fat. I will write the answers and provide the explanation.
Answer:
- Adipose Tissue: Adipose tissue, commonly known as body fat, is a type of connective tissue. It is composed of cells called adipocytes that store fat in the form of a lipid droplet. The primary function of adipose tissue is to store energy in the form of fat, cushion and protect internal organs, and insulate the body to conserve heat. Adipose tissue is found throughout the body, particularly under the skin (subcutaneous fat), around internal organs (visceral fat), and in the bone marrow.
- Smooth Muscle Tissue: Smooth muscle tissue is a type of involuntary muscle tissue that is found in the walls of hollow organs, such as the stomach, intestines, blood vessels, and the bladder. It is called “smooth” because it lacks the striations seen in skeletal and cardiac muscle tissue. Smooth muscle cells are spindle-shaped, with a single central nucleus, and contract to facilitate the movement of substances through the organs. Unlike skeletal muscle, smooth muscle contractions are involuntary and are controlled by the autonomic nervous system.
- Vacuole Containing Fat: A vacuole containing fat refers to the lipid droplets found within adipocytes in adipose tissue. These lipid droplets act as reservoirs for energy storage, releasing fatty acids when the body needs energy. The vacuoles are typically large, pushing the cell’s cytoplasm and nucleus to the periphery of the cell. When the body is in need of energy, the stored fat in the vacuoles is broken down into fatty acids and glycerol, which are then transported to other tissues to be used in cellular metabolism.
Explanation (300 Words):
Adipose tissue is a specialized form of connective tissue that plays several critical roles in the body. Its main function is to store energy in the form of triglycerides (fat), but it also serves as an insulator, keeping the body warm, and provides cushioning for vital organs. The adipocytes, or fat cells, in adipose tissue contain large lipid droplets in the cytoplasm. These vacuoles filled with fat droplets are crucial for storing energy. When the body needs fuel, the fat is broken down and released into the bloodstream.
Smooth muscle tissue, on the other hand, is responsible for involuntary movements within the body. Unlike skeletal muscle, which is under conscious control, smooth muscle operates autonomously, controlled by the autonomic nervous system. This type of muscle is found in the walls of various organs, including the digestive tract, blood vessels, and the bladder. Smooth muscle cells have a unique, spindle-shaped structure with a single central nucleus. These cells contract slowly but steadily to propel substances through the organs or constrict blood vessels.
The vacuoles in adipocytes are integral to the function of adipose tissue. These vacuoles store triglycerides, which the body uses as an energy reserve. During periods of fasting or exercise, the stored fat is broken down and released into the bloodstream to provide energy. This process is regulated by hormones, such as insulin and glucagon, and is essential for maintaining homeostasis and providing fuel during periods of low food intake. The presence of fat droplets within adipocytes highlights the energy-storage function of adipose tissue.
