Biology 12: The Cell Flashcards
Watery fluid found inside of a cell
 Cytoplasm
What is an organelle used for the storage of various substances within the cell?
 Valcuole
These substances are scattered in a mosaic throughout the cell membrane
 Proteins
The cell walls of plants are made from this polysaccharide
 Cellulose
What is the number of ribosomal subunits?
 2
The middle part of a cell membrane is called _____ because it is water fearing?
Hydrophobic
Organelles which stores and packages proteins within the cell
Golgi Apparatus
Short hair like structures which acid in a cell local motion
Cilia
Proteins that associate with DNA to form the chromosome
Histones
A dark region within the nucleus which produces rRNA 
 Nucleolus
The movement of molecules from areas of high concentration to areas of low concentration
 Diffusion
Specialized vacuoles which contain digestive enzymes used to break down unwanted materials within the cell
 Lysosome
Nuclear _____ are openings in nuclear membrane where substances made up in the nucleus can escape
Pores
This substance is made during photosynthesis and consumed during cellular respiration
Glucose/ Oxygen
The idea that all living organisms are composed of cells and it only sells can produce new cells
 Cell theory
Cellular _____ occurs in the mitochondria
 Respiration
This substance is a nuclear acid which is a structural component of ribosomes
Ribosomal RNA
A whip like projections from the cell used for locomotion
 Flagella
Cells which have a membrane-bound nucleus
Eukaryotic
Cells which do not have a true nucleus and are usually smaller in size
 Prokaryotic
 Protein _____ is controlled by the DNA and occurs at the ribosome
Synthesis
Paired structures found in animal cells which aid in the process of cell division and creation of basal bodies
 Centrioles
The structure found at the base of cilia or flagella
Basal bodies
A general term for describing pigment containing organelles found in only plant cells
 Plastids
_____ ER is were lipid production occurs
Smooth
Structure surrounding the cell membrane in plants cells
Cell wall
The part of the cell that contains the genetic information that controls the cells activities
 Nucleus
The part of the cell that produces proteins for the cell
 Ribosomes
