Parts of the cell Flashcards
A selectively permeable membrane composed of one lipid bilayer between two monolayers of protein and carbohydrates intercalating between the lipids and the proteins
Cell membrane or plasma membrane
These are projections that increase the absorptive function of the membrane
Microvilli
They are the infoldings or invaginations of the cell membrane, function of which is not only to increase the absorptive capacity of the cell surface but also help the cell take in food substances
Pinocytic Vescicles
This is the living substance of the cell. This is made up of organic and inorganic compounds as well as nucleic acids
Cytoplasm
This is considered as the circulatory system of the cell concerned with intracellular transport
Endoplasmic Reticulum (ER)
This is agranular endoplasmic reticulum (aER) without ribosomes
Smooth Endoplasmic Reticulum (sER)
This is also called the granular endoplasmic reticulum (gER) because its membrane is lines with ribosomes. This is necessary in protein synthesis
Rough Endoplasim Reticulum (rER)
These are spherical granules found either attached to ER or distributed in the cytoplasm performing protein synthesis
Ribosomes
These are cellular structures in the transport of substance to and from the cells
Golgi Complex or Disctyosomes
These are double-walled or rob-shaped structures with inside folds known as the cristae which increase the surface for energy production. The powerhouse of the cell
Mitochondria or Chondriosomes
They are referred to as the “suicide bags” because they contain enzymes that can digest cell components such as foreign bodies like bacteria
Lysosomes
They are present only in animal cells and primitive plants which are important in cell division
Centrosomes and Centrioles
These are empty spaces capable of storing food and the contractile for expelling wastes
Vacuoles
It is a rounded structure at the center of the cell which controls the metabolic activities of the cell
Nucleus
This is a double-layered membrane arising from the plasma membrane enclosing the nucleoplasm. It regulates the movement of materials in and out. It controls the passage of materials from the cytoplasm to the nucleus and vice versa
Nuclear Membrane
