The small membrane bound structures inside the cells are called cell organelles.
Cell organelles are usually classified on the basis of their membranes.
They are membrane less- ribosomes and centrosomes, single membrane- golgi body and endoplasmic reticulum and double membrane like plastids and mitochondria.
sponges!
Proteins are made up of smaller units called amino acids which are strung together to form proteins which can be of different sizes and shapes.
the repeating units of protein are called amino acids.
The osteon is the structural unit of compact bone. Haversian system is a microscopic, structural unit of compact bone also called the osteon. The osteons are arranged in multiple layers or rings called concentric lamella.
The basic structural and functional units of organisms are cells.
Tissues
Amino acids are the basic structural building units of proteins.
Proteins provide building blocks for the structural components of organisms.
Components of compact bone tissue are arranged into repeating structural units called osteons and haversian systems, each osteon consists of a central (haversian) canal with its concentrically arranged lamellae, lacunae, osteocytes and caniculi.
saccharide units>>> sugars
The particles in most solids from structural units called crystals. Crystals are a solid substance that have a geometrically shaped form.
Large molecules that contain carbon and are held together by covalent. They are the structural units of glycogen.
Large molecules that contain carbon and are held together by covalent. They are the structural units of glycogen.
cell
for this reason ceall are called structural and functional units of life
THe outer shell of a virus is called the capsid, and consists of various proteins, which are arranged to enable the virus to enter and control a host cell. These proteins are called protomers and are assembled in units called capsomeres.
Proteins are the main structural element that build the body. Actin, filamin, collagen, myosin are some important proteins that build cells and tissues of animals. they are normally fibrous in nature so as they found mostly in fibrous tissues such as tendons, ligaments, bones and so on.
