What are the different chemical components of the cytoplasm?
Cytoplasm chemically is composed of proteins, lipoids (which include fatty, phospholipid, and steroidal compounds), carbohydrates, mineral salts, and, of course, a good deal of water (in most cells more than 90%).
What does the cytoplasm do in a eukaryotic cell?
The cytoplasm, or cytosol of eukaryotic cells is the gel-like, water-based fluid that occupies the majority of the volume of the cell. Cytoplasm functions as the site of energy production, storage, and the manufacture of cellular components.
What is endoplasmic reticulum function?
The endoplasmic reticulum (ER) is the largest membrane-bound organelle in eukaryotic cells and performs a variety of essential cellular functions, including protein synthesis and processing, lipid synthesis, and calcium (Ca2+) storage and release.
What are the two main components of cytoplasm?
The cytoplasm is composed of two parts, the cytosol and organelles. Cytosol, the jelly-like substance within the cell, provides the fluid medium necessary for biochemical reactions.
How is the cytoplasm similar to the restaurant floor?
The restaurant floor holds tables, chairs and all objects in place, whereas the cytoplasm keeps all the organelles suspended in their places. The nucleus of a cell is like a restaurant manager as the nucleus has control over what happens in the cell just as a restaurant manager controls the activities in the restaurant.
How does the cytoplasm provide shape to the cell?
Cytoplasm provides shape to the cell. It fills up the cells thus enabling the organelles to remain in their position. The cells, without cytoplasm, would deflate and substances will not permeate easily from one to the other organelle. A part of the cytoplasm, the cytosol, has no organelles.
What makes up the jelly-like fluid of the cytoplasm?
The jelly-like fluid of the cytoplasm is composed of salt and water and is present within the membrane of the cells and embeds all of the parts of the cells and organelles. The cytoplasm also assists in metabolic activities.
What is the function of inclusions in the cytoplasm?
Cytoplasmic inclusions are particles that are temporarily suspended in the cytoplasm of a cell. They may be macromolecular or granules such as secretory and nutritive inclusions and pigment granules. Secretory inclusions secrete something out of them such as acids, enzymes and proteins.
