stratum basale
Yes, the oldest epidermal cells in the epidermis are found in the stratum basale. As new cells are continually formed in this layer through cell division, the older cells are pushed upward into higher layers of the epidermis.
Yes, the oldest epidermal cells are found in the stratum basale. This layer, also known as the basal layer, is the deepest layer of the epidermis and is responsible for the continuous production of new cells. As cells are pushed upwards, they become older and eventually reach the outermost layer of the epidermis, the stratum corneum, where they are shed.
Merkel cells compose about 8% of the epidermal cells. These specialized cells are found in the deepest part of the epidermis and are involved in the sensation of touch.
Plant epidermal cells are found on the outermost layer of plant tissue, covering the surfaces of leaves, stems, flowers, and roots. They serve various functions such as protection, gas exchange, and absorption of water and nutrients.
It is called Keratinocyte, which is in the outermost layer of the epidermis.
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.
Stratum granulosum Once again, stratum granulosum is one of epidermal layers: not epidermal cells. My answer to this question is: Flattened cells of stratum granulosum that are going through keratinization process contain kerathyaline and lamellated granules.
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.
No, epidermal cells do not have a secondary cell wall. The primary cell wall of epidermal cells is composed mainly of cellulose, hemicellulose, and pectin, providing support and protection to the cell. Secondary cell walls are found in specific types of cells, such as xylem cells in plants, for additional structural support.
Dividing cells found at the base of the epidermis are responsible for continual growth and regeneration of the epidermal layer. These cells undergo mitosis to produce new cells, which then move upwards, differentiating into specialized skin cells as they mature to replace the older cells shed from the skin surface.
Stomata are found in the epidermis of leaves, specifically in specialized cells called guard cells. Guard cells surround and control the opening and closing of the stomata to regulate gas exchange and water loss in plants.
