The endoplasmic reticulum is a membrane-bound organelle in cells of eukaryotic cells involved in protein synthesis, lipid synthesis, and calcium storage. There are two types of endoplasmic reticulum — the rough and the smooth type. The rough endoplasmic reticulum consists of flattened sacs and is ...
n., plural: smooth endoplasmic reticula (A part of) endoplasmic reticulum that is tubular in form (rather than sheet-like) and lacks ribosomes Source: modified by Maria Victoria Gonzaga, BiologyOnline.com, from OpenStax, CC BY 3.0.
The cytoskeleton is present inside the cytoplasm, which consists of microfilaments, microtubules, and fibres to provide perfect shape to the cell, anchor the organelles, and stimulate the cell movement. Endoplasmic Reticulum It is a network of small, tubular structures that divides the cell surface...
At the apex of the tube are active ribosomes andendoplasmic reticulum(types of cellorganelles) involved inproteinsynthesis. Pectinase and a glucanase (bothenzymesthat break downcarbohydrates) probably maintain flexibility of the growing tube and aid in penetration. The pollen tube apex also releases r...
Endoplasmic reticulum (ER) Description: It is a network of small, tubular structures. It divides the space inside of Eukaryotic cells into two parts – luminal (inside ER) and extra-luminal (cytoplasm). Structure: ER can be of two types – ...
Rhodophyta is defined as a group of red-colored algae which possess sulfated polysaccharides in the cell wall, floridean starch, phycobilin pigments, unstacked thylakoids, and chloroplasts devoid of endoplasmic reticulum, but lack flagella. They show complex alternation of generations and specialized ...
(ligands) bind to specific receptors on the surface of the membrane protein. Once bound, the target molecules are internalized by endocytosis. Receptors are synthesized by a cellorganellecalled theendoplasmic reticulum (ER). Once synthesized, the ER sends the receptors along to theGolgi apparatusfor...
Examples of Protist include Euglena, Amoebas, Paramecium, and Diatoms. These organisms all live in water and are made up of one cell with specialized organelles. A Protist can have specialized organelles, such as chloroplasts, mitochondria, endoplasmic reticulum, and lysosomes....
The sperm fuses with the membrane of the egg, releasing its genetic components into the egg's cytoplasm, leaving behind the tail and other organelles such as the mitochondria. Therefore, the zygote's supply of organelles, such as mitochondria, ribosomes, and endoplasmic reticulum, come from the...
–it is the region in the cytoplasm where the genetic material is present. a prokaryotic cell lacks certain organelles like mitochondria, endoplasmic reticulum, and golgi bodies. prokaryotic cell diagram the prokaryotic cell diagram given below represents a bacterial cell. it depicts the absence of ...
