Cytology Flashcards
Centrioles
Form spindle during mitosis
Parts of the cell
Plasma membrane, nucleus, cytoplasm
Centromere
Keeps the 2 identical strands of each chromosome attached
Centrosome
Two centrioles; organizes microtubules; participates in spindle formation during cell division
Chromatids
Duplicated chromosomes- sister chromatids
Chromatin
Loosely coiled DNA: DNA can direct the production if cellular proteins (transcription)
Chromosome
Most compact, organized level of genetic material; visible in the cell only when dividing
Cilia
Move substances over cell surface
Cytoplasm
Place of many metabolic processes in the cell
Cytosol
Contains ions used in cellular functions; support for organelles; viscous fluid medium through which diffusion occurs
Cytoskeleton
Maintains intercellular structural support and organization of cells; participates in cell division; facilitates movement
DNA
Genetic material that directs protein synthesis
Flagella
Propels sperm
Golgi apparatus/body
Modifies, packages, and sorts materials arriving from ER in transport vesicles; forms secretory vesicles and lysosomes
Inclusion bodies
Serve as temporary storage for molecules such as melanin, proteins, glycogen, lipids
