Lesson 3 Flashcards
Fundamental unit of any living organism
Cells
Chemical reaction that occurrs in the cell
Metabolism
Makes up the genes of chromosomes
DNA
Tiny organlike structures
Organelles
Fewer complex cells, which include Bacteria and Archaea
Prokaryotes
More complex, containing true nucleus and many membrane bound organelles
Eucaryotes
Prokaryotes or Eucaryotes : algae, protozoa, fungi, plants, animals
Eucaryotes
Is virus cellular or acellular
Acellular
The study of the structure and function of cells
Cytology
Eu means
True
Refers to nut or nucleus
Caryo

Cell membrane
Cell membrane is also referred as
Plasma, cytoplasmic, cellular membrane
The skin like around the cell
Cell membrane
Control the functions of the cells
Nucleus
Command center of the cell
Nucleus
Three components of nucleus:
Nucleoplasm
Nuclear membrane
Chromosomes
Embedded or suspended in the nucleoplasm
Chromosomes
A gelatinous matrix or base material of the nucleus
Nucleoplasm
Serves as skin of the nucleus
Nuclear membrane
Semi-fluid, gelatinous, nutrient matrix
Cytoplasm
It is where most of the cell’s metabolic occur
Cytoplasm
Semifluid of the cytoplasm
Cytosol
Located along the DNA molecules
Genes
This controls the appearance and growth
Genes
The beads on the string of DNA
Genes
It carries the genetics
Chromosomes
Meaning of ATP
Adenosine Triphosphate
Energy carrying molecules
ATP
Membranes that are interconnected and arranged to form a transport network of tubules and flattened sacs
Endoplasmic reticulum
An ER that has rough, granular appearance when observed
Rough ER
Smooth or Rough ER: many ribosomes attached to the outer surface
Rough ER
Smooth or Rough ER: ribosomes are not attached
Smooth ER
Consist mainly of rRNA and protein.
Ribosomes
It plays an important part in the synthesis of proteins
Ribosomes
Clusters of ribosomes
Polyribosomes / Polysomes
Also known as Golgi Apparatus or Golgi Body
Golgi complex

Photosynthesis
Three types of cytoskeletal fibers
Microtubules
Microfilaments
Intermediate filaments
Another term for microfilaments
Actin filaments
Cytoskeleton that are essential for cell division, contraction, motility, and movement of chromosomes
Microtubules
Microfilaments
