Exercise 3: Animal Cell Flashcards
is the study of cell?
Cytology
solid inclusions which re rare in animals cells but more common in plant cells. Example calcium oxalate
Crystals
are non-membrane delimited structures often associated with oriented movement.
Microtubules and microfilaments
are minute cavities having more fluid content than the rest of the cytoplasm and surrounded by a membrane called tonoplast.
Vacuoles
is a viscous fluid and heterogeneous system consisting mostly of water and is composed principally of CHON although other elements such Ca, K, Na and S are also present.
Cytoplasm
living, indispensable parts of the cell.
Cytoplasmic organelles
Consider as the chief center of cellular respiration
Mitochondria
From the standpoint of anatomy (based on organization components) the cell may be roughly be divided into two components: the two components are?
Plasma membrane and protoplasm
the most conspicuous body in the cell surrounded by the cytoplasm. Considered as the “governing body” of the cell,
Nucleus
a dark containing, spherical body in the nuclear sap believed to be the center of protein and RNA synthesis.
Nucleolus
Is a membrane-delimited body containing a hydrolytic enzyme which plays an important role in digestion. “Suicidal bags”
Lysosomes
doubled layer membrane surrounding the nucleus which is continuous with ER membrane.
Regulates entrance and exit of substances into and out of the nucleus.
Nuclear membrane
a colorless fluid within the nucleus, containing chromatin granules / materials for building DNA
Nucleoplasm (nuclear sap or karyolymph)
small dense particles associated with rough ER seat of protein synthesis.
Ribosomes
Consist of a stack of several membranous saccules with associated vacuoles and vesicles.
Believed to be a site for the concentration of protein polysaccharide.
Golgi bodies
