What else can I help you with?
Are there cilia at the apical surface?
Yes, cilia are present on the apical surface of some cells. They serve various functions, such as moving substances along the cell surface or sensing the environment.
What is an apical cell?
An apical cell is the primary cell located at the tip of a plant shoot or root. It is responsible for the growth and development of the plant by producing new cells through cell division. The apical cell is important for determining the overall shape and structure of the plant.
Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
Apical epithelial cell structures, such as microvilli and cilia, increase the surface area of the cell for absorption and movement of substances. Microvilli aid in absorption, while cilia facilitate the movement of materials along the cell surface, such as in the respiratory tract for mucus clearance.
What is the significance of the basolateral side in cellular function and how does it differ from the apical side?
The basolateral side of a cell is important for communication and transport of molecules, while the apical side is specialized for absorption and secretion. The basolateral side is involved in interactions with neighboring cells and the extracellular environment, while the apical side is more focused on specific functions related to the cell's role in the body.
An epithelial cell can be divided into two functional regions They are the surface and the surface?
An epithelial cell can be divided into two functional regions: the apical surface, which faces the external environment or a body cavity, and the basolateral surface, which interacts with neighboring cells and the extracellular matrix. These regions are important for different functions such as absorption, secretion, and cell-cell communication.
How does the structure of cells near the apical meristem compare with the structure of cells far from the apical meristem?
Cells near the apical meristem are generally undifferentiated and actively dividing, while cells far from the apical meristem are often differentiated and specialized for specific functions. This means that cells near the apical meristem are smaller in size and have thin cell walls, whereas cells far from the meristem are larger and more specialized in structure and function. Additionally, the cells near the apical meristem may have fewer organelles and vacuoles compared to those far from the meristem.
Location of nucleus in columnar epithelial cell?
The nucleus in a columnar epithelial cell is typically located towards the base of the cell, closer to the basement membrane. This positioning allows for efficient packing of organelles in the apical region of the cell, facilitating secretion and absorption functions of the cell.
Roots and shoots lengthen through activity at?
Roots lengthen through cell division at the root tip in the zone of elongation, while shoots lengthen through cell division in the apical meristem located at the shoot tip. The apical meristem is responsible for the growth of new cells and tissues in both roots and shoots, allowing the plant to increase in length.
What side of epithelial faces the lumen?
Apical Border is the side of an epithelial cell that faces the lumen.
What is the shape of apical and marginal cell of hydrilla?
In HPO, it has a rectangular shape and in LPO, it is elongated shape in LPO.
What are the sites of cell growth in plants called?
They are called meristems or apical meristems when they are located at the tips of roots.
Cells in which nucleus and cytoplasm are pushed against a cell membrane?
These cells are likely epithelial cells, which are specialized for protection, absorption, and secretion. The nucleus is typically located near the base of the cell due to the presence of organelles in the apical cytoplasm that help in these functions. The arrangement of nucleus and cytoplasm allows for efficient communication and transportation of substances across the cell.
