Cell Theory |
All cells are created from other cells |
How cells reproduce |
|
Prokaryotes |
Small, single-cell bacteria |
Simplest structure of life |
|
Eukaryotes |
Organisms that contain a nucleus which can be single or multi-cellular |
Animals are these |
|
Nucleus |
Organelle that holds DNA |
"Brain of the cell" |
|
Chromosome |
Threads of proteins and DNA passed down genetically |
Normal humans have 22 pairs |
|
Nucleoid |
Single cellular chromosome that holds most of genetic material. Found without membranes. |
In prokaryotes |
|
Plasmids |
Part of DNA that can separate from chromosomes which send important genetic info to other cells |
In bacteria and yeast |
|
Flagella |
Tails of cells made from proteins |
They resemble long strings |
|
Cell/Plasma Membrane |
Membrane separating interior and outside of cell |
Selectively permeable membrane |
|
Cell wall |
Layer of polysaccharides that serve as a boundary on the outside of a cell |
Found on the exterior of plant cells |
|
Ribosomes |
Builds proteins within cells |
Connected amino acids that make chains |
|
Cytoplasm |
Fluid within cell membrane that takes up empty space |
Also called protoplasm |
|
Cytosol |
Cytoplasm that's water-soluble which surrounds organelles |
Made from proteins plus water and salt. |
|
Organelles |
Structures inside eukaryote cells |
Ex.: mitochondria, nucleus |
|
Nucleolus |
Structure inside nucleus constructed of RNA and proteins |
Makes ribosomal subunits |
|
Cytoskeleton |
Fibers that maintain the shape of the cell |
Helps cell to move and divide |
|
Microtubules |
Helps organelles to move and supports cell shape |
Part of cytoskeleton |
|
Rough ER |
Surrounded by ribosomes and transports proteins |
Membranes that look like tubes |
|
Smooth ER |
Makes lipids and hormones |
In eukaryotes like plants and animals |
|
Golgi apparatus |
Receives proteins and fats and makes molecules to transport and store |
Works with rough ER |
|
Vesicles |
Transports and stores cellular products and they get rid of waste from metabolism |
2 sacks made of fluid |
|
Vacuoles |
Store nutrients and waste for cell survival |
Found in plants and animals |
|
Centrioles |
Ensures cell division in mitosis and meiosis |
They are found forming a right angle |
|
Cilia |
Helps cell movement |
Looks like hair identical to flagella |
|
Lysosomes |
Vesicle that stores enzymes |
Sends products of ER to Golgi apparatus |
|
Mitochondria |
Makes ATP and is the location of ETS |
"Powerhouse of the cell" |
|
Chloroplasts |
Produces food and converts light energy to sugars |
In plant cells |
|
Colony |
Microorganisms from one large, visible cell |
From Mother cell of the same species |
|
Multicellular |
Organism made of more than 1 cell |
Eukaryotes |
|
Cell differentiation |
When unspecialized cells mature to complete specific jobs |
Major change in cell form |
|
Tissue |
group of cells with the same function and structure |
Found in multicellular organisms |
|
Organ |
Group of tissues that complete a specific function |
Ex.: stomach, heart |
|
Organism |
A living thing or system |
Animal, plant, bacteria |
|
Organ system |
Group of organ working together to complete a goal |
Respiratory system |
