Cells Flashcards
All earth organisms
Common biological molecules
Composed of cells, homeostasis
Require water
No simple definition of life
Growth movement
Elements
Fundamental forms of matter
Atoms
The smallest unit of an element
Ions
Atoms with an electrical charge
Atomic number
Determined by the number of protons in the nucleus
Molecule
Two or more atoms held together by chemical bonds
Suspension
Separates
Colliod
Stays together
Hydrophilic
Water loving
Hydrophobic
Fear of water
Proteins
Polymers of amino acids
Carbohydrates
Energy
Proteins
Build tissue
NUCLEIC acid
Blue print
Prokaryotic
Bacteria, simple, earliest cell
Eukaryotic
Have a membrane, nucleus, and is complex
Plasma membrane
All cells surrounded by
Nucleus
Surrounded by nuclear membrane which houses DNa
Ribosomes
Assemble proteins
Cytosol
Watery substance that surrounds the nucleus and organelles
Mitochondria
Provide energy. ATP
Chloroplasts
Sites of photosynthesis in plant cells
Lysosomes
Contain digestive enzyme to break down substances
Smooth ER
Lipid synthesis and locks ribosomes
Rough ER
Protein synthesis and has ribosomes attached to it
Golgi body
Modifies and sorts proteins and packages them into vessels
Centrioles
Moves genetic material during cell division
Cytoskeleton
Maintains cell shapes
Central vacuole
Found in plant cells and stores water starch and pigments
Nucleolis
Makes ribosomes
The theory of evolution
Common ancestor. Prokaryotes and eukaryotes
Organic chemistry
The chemistry of the complex carbon containing molecules
