Szivacsejtek

Szivacsejtek, often translated as sponge cells, is a term used to describe cells that exhibit a porous or sponge-like structure. These cells are characterized by the presence of numerous cavities or vacuoles within their cytoplasm. The size and distribution of these cavities can vary significantly depending on the cell type and its function. In some cases, these spaces may be filled with water, air, or other substances.

The porous nature of szivacsejtek can serve various purposes. In plant cells, for example, enlarged intercellular spaces within the spongy mesophyll layer of leaves facilitate gas exchange, allowing carbon dioxide to reach photosynthetic cells and oxygen to diffuse out. In certain animal tissues, sponge-like cells might be involved in absorption or filtration processes, where their increased surface area aids in the uptake of nutrients or the removal of waste products. The specific function of szivacsejtek is directly related to the organism and tissue in which they are found. Their morphology is an adaptation that enhances their biological role. The term itself is descriptive of the visual appearance rather than denoting a specific lineage or universal cellular process.
