Prokaryotes Cells
Cells that have no nucleus or any other membrane-bound organelles
Cell components that perform particular functions
Eukaryotic Cells
Cells that contain membrane-bound intracellular organelles, including a nucleus
Schleiden & Schwann
these scientists developed the cell theory
Cell Theory
All living things are made up of one or more cells, Cells are the basic units of life, All cells come from pre-existing cells
Organelles that make energy available to the cell
Endocytic Vesicles
These form when the plasma membrane surrounds a molecule outside the membrane then releases a membrane-bound sack containing the desired molecule into the cytoplasm. This allows the cell to absorb things that cannot pass through the cell membrane.
Projections of the cell extending from the cell membrane. They increase surface area available to absirb nutrients
Provides structural support to a cell
Long, hollow, cylindrical protein filaments, which give structure to a cell.
Double-stranded chains of proteins which assist in giving structure to the cell. Works with Microtubules to form the cytoskeleton
Structural component of the cell. Microtubules arranged in a pinwheel shape that actually form new microtubules.
the site of protein synthesis within a cell (Free & Attached)
Endoplasmic Reticulum
A large organization of folded membranes which is responsible for the delivery of lipids and proteins to the cytoplasm (Rough & Smooth)
Golgi Apparatus
This organelle is instrumental in storing, packing, and shipping of proteins to different parts of the cell
These organelles digest unused material within the cell
Cell Wall, Chloroplast, Central Vacuole
Three plant cell organelles not found in animal cells
Passive Transport, Active Transport, Facilitated Diffusion
Three methods through which substances can cross the cell membrane
Passive Transport
Method in which substances can pass through the cell membrane without the cell expending any energy
Active Transport
Method in which substances can pass through the cell membrane that requires the cell to expending energy
Facilitated Diffusion
Method in which substances can pass through the cell membrane that does not require added energy, but cannot occur without the help of specialized proteins
Process whereby large molecules are engulfed in a pocket of cell membrane and absorbed into the cell
A substance that lowers the activation energy of a reaction
These are synthesized at the ribosomes, just like all proteins
The light, decomposition reaction of photosynthesis
CO2 Fixation
The dark reaction of photosynthesis
The breaking down of the glucose into smaller carbon-containing molecules yielding ATP
the first step of all cellular respiration and occurs in the cytoplasm
Glycolosis is a(n) …………reaction
Krebs Cycle & Electron Transport
Aerobic respiration begins with glycolosis and proceeds through these two steps…
Krebs Cycle
This portion of aerobic respiration oocurs in the matrix of the mitochondria and breaks down pyruvic acid molecules into CO2, H+, and 2 ATP molecules
Anaerobic respiration is also called….
