ANIMAL CELL Flashcards
It is the study of cell.
CYTOLOGY
It is the smallest of protoplasm capable of the independent existence and is therefore, the basic unit of life.
CELL
What are the 2 Components of the Cell?
PLASMA MEMBRANE and PROTOPLASM
It is the outer limit of the cell which controls the passage of substance from the internal environment of the cell to the exterior and vice versa. Therefore, acts as a selective “gate keeper” of the cell.
PLASMA MEMBRANE
It is the living substance within the cell composed of nucleus and cytoplasm. This is an aggregate of crystalloids and colliods. A fluid, viscid and more or less transparent part of the cell.
PROTOPLASM
What are the elements that composes the cell?
96%- carbon, oxygen, hydrogen and nitrogen and some traces of Ca, P, K, S, I, Na, Cl,Mg, Cu, Co, Mn, Zn and etc.
What are the inorganic compounds?
Water, salts, minerals and gases
What are the organic compound?
Carbohydrates, protein, lipids and nucleic acids.
It is the most conspicuous body in the cell sorrounded by the cytoplasm; th3 governing body of the cell.
NUCLEUS
It is a double layer membrane sorrounding the nucleus which is continuous with ER membrane.
NUCLEAR MEMBRANE
A colorless fluid within the nuclei, containing chromatin granules/ materials for building DNA.
NUCLEOPLASM ( nucleic sap or karyolymph)
It is a dark containing, spherical body in the nuclear sap believed to be the center of protein and RNA synthesis.
NUCLEOLUS
These are threadlike structures which comdense and become chromosomes during cell division.
CHROMATIN
It is a vicous fluid and heterogeneous system consisting mostly of water and is composed principally of CHON although other elements such as Ca, K, Na and S are also present.
CYTOPLASM
Living, indispensable parts of the cell.
CYTOPLASMIC ORGANELLES
What are the inside of Cytoplasmic Organelles?
1.) Endoplasmic Reticulum
2.) Ribosomes
3.) Golgi bodies
4.) Lysosomes
5.) Mitochondria
6.) Centrioles
7.) Microtubules and Microfilaments
It is a tubular network of membrane delimited structures.
ENDOPLASMIC RETICULUM
What are the two types of ER?
ROUGH ER and SMOOTH ER
It is where the ribosomes are attached.
ROUGH ER
It lacks of ribosome, concerned with fatty acids synthesis, glycogenesis and glycogenolysis.
SMOOTH ER
It is a small dense particles associated with rough ER seat of protein synthesis.
RIBOSOMES
It consist of a stack of several membranous saccules with associated vacuoles and vesicles; packaging of proteins and lipids.
GOLGI BODIES
It is a membrane-delimited body containing a hydrolytic enzyme which plays an important role in digestion.
LYSOSOMES
These are ovoid, granular, filamentous or sausage-shape bodies. Consider aa the chief center of celkular respiration ( power house of the cell).
MITOCHONDRIA
