Is mitochondria more abundant in human epithelial cells or in onion epidermal cells?
Yes. In an animal, more mitochondria is needed to allow movement and conduction. In plants, on the other hand, not only is the cell occupied by the large central vacuole, but it is also filled with many plastids such as chloroplasts. Because of this not a lot of mitochondria can fit in.

What cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.
Comparison between epidermal tissue of plants and epithelial tissue of animals?
Epidermal tissues in plants includes several differentiated cell types. They are epidermal cells, guard cells, subsidiary cells, and epidermal hair. Many plants have waxy cuticle layer deposited on top of the epidermal cells. Epithelial tissues consist of epithelial cells which form continuous sheets that are attached to each other at many locations by tight junctions and desmosomes. Both plant epidermal tissues and animal epithelial tissues form the most numerous and largest tissues for their specific organisms. Both plant epidermal tissues and animal epithelial tissues also are very densely packed together, leaving very little intercellular space. The plant epidermal tissues functions in prevention of water loss and act as a barrier to fungi and other invaders. It also regulates gas exchange in plants and absorb water and minerals nutrients(especially in roots) The epithelial tissues not only covers the external environment of plant from the external environment but also lines the surfaces of internal organs of an organisms, unlike the plant epidermal tissues that only act as barrier between external environment and external environment.Functions of epithelial tissue includes secretion, selective absorption, protection. transcellular transport and detection of sensation. Other than that, both of the structure act mainly as protective barrier between the internal environment of living thins and the external environment.
Are epidermal cheek cells pigmented?
No, epidermal cheek cells do not contain pigments. Pigments such as melanin are produced by melanocytes located in the basal layer of the epidermis and transferred to surrounding keratinocytes, providing skin coloration. Cheek cells mainly consist of epithelial cells that do not contain melanin.
What organelle is abundant in the muscle cells?
The organelle which is more abundant in muscle cells than in other cells is mitochondria. This is due to the fact that muscle cells require more energy than any other cells.
What does stratum germinativum produce epidermal epithelial cells through?
The stratum germinativum, also known as the basal layer of the epidermis, produces epidermal epithelial cells through a process called mitosis. In this layer, basal cells continuously divide and push older cells upwards toward the surface of the skin. As these cells migrate, they undergo a process of keratinization, eventually forming the outer protective layer of the skin. This regenerative process is essential for maintaining the integrity and health of the epidermis.
What is the Epithelial tissue made up of?
It consists of two cells. The epidermal cells and the guard cells.
What cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.

What organelle is abundant in the muscle cells?
The organelle which is more abundant in muscle cells than in other cells is mitochondria. This is due to the fact that muscle cells require more energy than any other cells.
What organelle would athletes have more of?
The answer is mitochondria. Athletes have more muscles, therefore more mitochondria, which are abundant in muscle cells.Also see: What_organelle_do_athletes_have_more_of_than_sedentary_individuals
What is an epidermal cell?
An epidermal cell is a cell that is part of the outer layer of an organism. For example, in humans, skin cells are epidermal. Leaves on plants have epidermal layers on the top and bottom of the leaf.
What structure observe in onion epidermal cells are not present in human epithelial cells?
The structure of onion epidermal cells refers to the arrangement of tissues in this cells. You can find the structure of onion epidermal cells online athttp://biology.touchspin.com/onion_epidermis.php. The structures observed in an onion epidermal cell, which are not present in the human epithelial cells are cell wall, central vacuole and vacuolar membrane.
Do cells need mitochondria?
Most cells do. Multicellular organisms like humans need to create abundant amount of ATP, a feat that can only achieved with the help of mitochondria.
What are some differences between epithelial cells and muscle cells?
One difference between epithelial cells and muscle cells is their location in the human body. Epithelial cells are skin cells on the outside of the body. Muscle cells are located in the muscle under the skin.
What organelle is abundant in kidney tububle cells?
Mitochondria are abundant in kidney tubule cells due to their high energy demands for active transport and metabolic processes involved in regulating fluid and electrolyte balance. Mitochondria generate ATP through aerobic respiration to fuel these energy-demanding cellular functions in kidney tubule cells.
Is large amount of extracellular matrix a characteristic of epithelial tissue?
No, epithelial tissue is primarily composed of closely packed cells with minimal extracellular matrix. The extracellular matrix is more abundant in connective tissue, which provides structural support and anchorage for epithelial cells.
