The differences in cell type arise from the process of selective gene expression, which means that different sets of genes are activated or repressed in each cell type. This results in the production of specific proteins and ultimately determines the cell's function and characteristics. For example, red blood cells express genes that make them specialized for oxygen transport, while white blood cells express genes that make them part of the immune system.
Its part of a plant cell, a tube that carries energy.-----------------A Xylem cell is a plant cell. The xylem is the woody part of the tree. It is all of the cells between the pith in the center out to the cambium. The xylem consists of the sapwood and the heartwood. There is no one cell called a "xylem cell". Any cell in the xylem portion of the tree could be called a xylem cell.The vessels and/or tracheids in the outer few growth rings in the sapwood carries sap or water (with dissolved minerals) up to the leaves. The inner bark cells carry the food made by the leaves down the tree for use and for storage. The ray cells transport the food radially into the tree for growth. Also the rays cells can transport stored food radially outward in times of shortages or special needs. (like repairing damage by weather or disease or insects or animals, etc.)Phloem
No, xylem cells do not have cell membranes. Xylem cells are part of the plant's vascular system and are dead at maturity, so they lack cell membranes. Instead, xylem cells are composed primarily of cell walls that provide structural support and allow for the transport of water and minerals.
has a cell membrane
Xylem cells carry water and nutrients from the roots to other parts of a plant.
Tylosis is an out growth from a neighbouring cell to inside a xylem cell .
it is used for plants
store water
cell wall, central vacuole, and chloroplasts
It is not a cell. It is a plant tissue which conducts water
No, xylem cells are "dead" cells and therefore do not undergo cell division.
the differences between the paramecuim cell and the elodea cell is that paramecuim- hunt for food, live by itself, single cell creature. elodea- make their onw food, cannot live alone, multicullar cells. (lots of cells)
