Bacterial and archaeal cells are organized at the cellular and molecular levels. What part of the cell helps control what enters and leaves the cell? Key Takeaways Organelles are structures within a cell that perform specific functions like controlling cell growth and producing energy. Plant and animal cells can contain similar types of organelles. However, certain organelles can only be found in plant cells and certain organelles can only be found in animal cells. Examples of organelles found in eukaryotic cells include: the endoplasmic reticulum (smooth and rough ER), the Golgi complex, lysosomes, mitochondria, peroxisomes, and ribosomes. More items...

This book presents a broad range of topics related to the design requirements for engineering neural tissue Most of the cell’s genetic material (DNA) is in the nucleus. The shape and size of a cell is indeed related to its function. For example, the nerve cells are elongated in shape and are thin and dainty. This helps in transmitting the signals easily. 2. Structure of the Cell Wall •Provides shape and strong structural support •Most are rigid because of peptidoglycan content •Target of many antibiotics- disrupt the cell wall, and cells have little protection from lysis •Gram-positive cell (2 layers) –A thick (20 to 80 nm) petidoglycan cell wall and membrane •Gram-Negative Cell (3 layers) Entities can be unicellular or multicellular. understanding their physiological functions. al living organisms are composed of one or more cells.
