Cell Parts:Parts of the cell are called organelles. Named for their organ like appearance and function, these parts each do a different job to help keep the cell alive, much like the organs in our body do.Answer and Explanation: The function of the cell membrane is to protect the cell,...
What is the function of a plant cell? Which two domains consist of prokaryotic cells? In a plant cell, what is the function of the cell membrane? What are the functions of B-cells ? Why are mitochondria considered prokaryotic? What is the function of food vacuole in an amoeba?
What is the function of cell cortex?A.Although actin is found throughout the cytoplasm of a eukaryotic cell, in many cells it is highly concentrated in a layer just beneath the plasma membrane. In this region, called the cell cortex, actin filaments are linked by actin-binding proteins into...
What is the function of the cell wall in an onion cell? Building Blocks Of Living Organisms: Cells are the fundamental building blocks of all living things, including plants. Plant cells are eukaryotic, which means that they are complex with many structures and organelles that keep them alive ...
Plasma membrane of the cell is a living motile (fluid) structure having lipids, proteins and externally attached sugars. It has a number of functions such as providing shape to cell, acting as mechanical barrier between cell contents and environment, sel
