Cell Theory
every organism contains cells
Cell is smallest unit of Life
Only living things make new cells
DNA is not enclosed in a nucleus
Generally the smallest, simplest cells
Prokaryotic Cells
DNA is enclosed in a nucleus
Have many specialized cell parts called organelles
Eukaryotic Cells
Function: Medium for chemical reactions of the cell
Cytoplasm
Structure: Thick jellylike substance, 70% water, 30% proteins, fats, nucleic acids and mineral ions
Cytoplasm
Structure: fluid filled cigar shaped with a double layer membrane. Inner layer is folded. Folds are called cristae.
Mitochondria
Function: Aerobic respiration. “Powerhouse of the cell
Mitochondria
Structure: Network of fluid-filled tubelike structures usually connected to the nuclear membrane.
Endoplasmic Reticulum
Function: Transports proteins throughout the cell. “Subway of the cell
Endoplasmic Reticulum
Ribosome containing ER produces proteins
Rough Endoplasmic Reticulum
ER producing Limpids
No proteins
Smooth Endoplasmic Reticulum
Structure: Sets of flattened, slightly curved sacs with small vesicles often on the ends.
Golgi Body
Function: process sugar side chains of proteins, sort them and package them in vesicles for shipment to the cell membrane or other regions of the cell.
Golgi Body
Structure: Membrane bound fluid filled compartments
Vacuoles
Function: Storage of food, water and minerals
Vacuoles
Structure: Small membrane bound spheres containing digestive chemicals
Lysosomes
Function: Digestion and breakdown of molecules, dead cells and worn out cell parts
Lysosomes
Structure: Long, thin, threadlike structures made of protein
Microfilaments
Function: Locomotion of cells, changes in cell shape, contraction of skeletal muscle
Microfilaments
Structure: Long, thin, hollow rods made of protein
Microtubules
Function: Maintains cell structure, movement of cell parts throughout cell interior,movement of genetic material in cell division, locomotion of cell
Microtubules
Structure: Large numbers of short hairlike structures. Made of 9 sets of microtubules in a circular arrangement with 2 in the middle
Cilia
Function: Locomotion of some unicellular organisms and locomotion of some specialized cells in multicellular organisms
Cilia
Structure: Long singular or paired hair like structures. Made of 9 sets of microtubules in a circular arrangement with 2 in the middle
Flagella
Function: Locomotion of some unicellular organisms and locomotion of some specialized cells in multicellular organisms
Flagella
Structure: Cylindrical structures made of 9 sets of microtubules arranged in a circle. Found in pairs near nucleus.
Centrioles
Function: Play a role in cellular reproduction.
Found only in animal cells
Centrioles
Structure: Cylindrical structure made of 9 sets of microtubules arranged in a circle.
Basal Body
Function: Attaches flagella and cilia to the interior of a cell.
Basal Body
Structure: Double membrane bound central spherical organelle with pores in the membrane
Nucleus
Function: Cell control center. Contains genetic information
Nucleus
Structure: Small spherical body in nucleus
Nucleolus
Makes RNA of ribosomes
Nucleolus
Structure: Dense mass of protein and DNA found in the nucleus
Chromatin
Function: Carries genetic material.
Chromatin
Structure: Thread-like structures made of chromatin
Chromosomes
Function: Carries genetic mateial
Chromosomes
Structure: membrane bound fluid filled organelle. Fluid is called stroma. Also contains stacks of membranes called grana.
Chloroplasts
Function: photosynthesis. Grana contain chlorophyll that traps light. Glucose is made in the stroma
Found only in plant cells
Chloroplasts
Structure: Rigid outer layer made of starch called cellulose. Located outside the cell membrane
Cell Wall
Function: Gives structure and shape to cells and provides support for land plants.
Found only in plant cells
Cell Wall
