First set

By spinning at increasing speeds and removing the supernatant of a cell homogenate it is possible to collect smaller and smaller components of the cell.	Components found in all cells
Plasma membrane, Cytosol Chromosomes Ribosomes	Components found only in plant cells
Chloroplasts Central vacuole and tonoplast Cell wall Plasmodesmata	Components found only in animal cells
Lysosomes Centrioles Flagella	In prokaryotic cells DNA is concentrated in this region
The nucleoid	Difference betwwen cytoplasm and cytosol
Cytosol is a semifluid substance where organelles are found, whereas the cytoplasm is the entire region between nucleous and plasma membrane	Selective barrier that allows sufficient passage of oxygen, nutrients and wastes. Composed of a double membrane of phospholipids

Plasma membrane	Organelles with double membranes
Nucleus Mitochondria Chloroplast	Organelles that contain DNA
Nucleus Mitochondria Chloroplast	Ribosomal RNA is synthesized and assembled with proteins to build ribosomes in this region of the nucleus
The nucleolus	Ribosomes build proteins in these regions of the cytoplasm
Cytosol and outer side of the endoplasmic reticulum	In this membranous organelle lipids are synthesized, carbohidrates are metabolized and drugs are detoxified
Smooth Endoplasmic reticulum	Cell fractionation is a technique employed to isolate different components of the cell. It is mostly based in the principle that..

Second set

Rough endoplasmic reticulum	Here proteins made in the endoplasmic reticulum are modified, stored and sent to other locations
Golgi apparatus	Proteins specialized in production of products that will be secreted have large…
Endoplasmic reticulum and Golgi apparatus	Face of the Golgi apparatus closer to the endoplasmic reticulum
Cis face	Face of the Golgi apparatus where transport vesicles depart to other cell locations
Trans face	This organelle provides the acidic environment needed by hydrolitic enzymes to digest all major classes of macromolecules.
Lysosomes	Food vacuoles and lysosomes participate in this process

Fagocytosis	Holds reserves of important organic compounds as well as inorganic ions. It is enclosed by the tonoplast
Plant central vacuole	Energy producing organelle with an inner membrane that separates the intermembrane space and the matrix
Mitochondria	Organelle that has a double membrane, thylakoids and stroma
Chloroplast	Amyloplasts, chromoplasts and chloroplasts are all …
Plastids!!	These organelles use oxygen to break fatty acids, detoxify alcohol and other poisons as well as start the conversion of fatty acids to sugars in fat storing tissues of plant seeds
Peroxisomes	In this organelle ocurrs the synthesis of proteins that will be secreted from the cell via transport vesicles

Third set

Motor molecules	Hollow tubes Involved in cell motility chromosome and organelle movement. They are made of α and β-tubulin
Microtubules	These intertwined strands of actin participate in muscle contraction, cell division and formation of pseudopodia
Microfilaments	They are made of keratin and are important for anchoring the nucleous and maintenance of cell shape
Intermediate filaments	Microtubules grow out of these regions. In animal cells centrioles are found here.
Centrosome	They differ in length, beating pattern and number per cell but are made of microtubules
Cilia and flagella	Its structure is identical to that of the centriole and is the anchor for flagella and cilia
Basal body	Their role is to bear tension. In conjunction with other proteins they form a scafold just inside the membrane helping support the cell’s shape
Microfilaments	These structures extend and contract through the reversible assembly of actin subunits into microfilaments and of microfilaments into networks that convert cytoplasm from sol to gel
Pseudopodia	Like microtubules they are specialized in bearing tension. These structures are permanent fixtures of cells and constructed from a subunits belonging to the keratins
Intermediate filaments	These structures are important to integrate cells into tissues
Tight junctions, desmosomes and gap junctions	Collagen, proteoglycans, fibronectin and integrins are components of …
Extracellular matrix	By allowing components of the cytoskeleton to slide past each other they bring about movements of cilia and flagella, muscle cell contraction. They also participate in vesicle movement
