Prokaryotic Cells
Prokaryotic cells are simple, single-celled organisms that lack a nucleus and membrane-bound organelles. They include bacteria and archaea.
Eukaryotic Cells
Eukaryotic cells have a nucleus and membrane-bound organelles, making them more complex than prokaryotic cells. They are found in plants, animals, fungi, and protists.
Cell Membrane
Thin flexible structure that surrounds the cell. Regulates what enters and exits the cell
Nucleus
Brain of the cell controls functions of cell and contains DNA of cell
Cytoplasm
Jelly-like fluid in which organelles are found. This is where many chemical reactions take place within the cell
Mitochondria
Converts the energy stored in food to usable energy for the cell - cell respiration
Ribosome
A ribosome is a tiny structure in cells that makes proteins
ER
network of tubes that transport proteins within the cell. rough ER has ribosomes and smooth ER has no ribosomes
Golgi Apparatus
They package, sort, and ship proteins and other materials to where they’re needed in or out of the cell.
Vesicles
Are small packages carrying proteins, nutrients and water into, out of, and around the cell controls functions
Vacuoles
Temporary storage areas; assist in regulating water (usually bigger in plant cells)
Lysosomes
Contain digestive chemicals that break down food particles, cell wastes, and worn-out cell parts
Cell Wall
Rigid outer wall that provides protection support and shape contains pores to allow substances to pass.
Chloroplast
Captures light to synthesize food energy. Contains green pigment chlorophyll.
Diffusion
Diffusion is the movement of particles from an area of high concentration to low concentration until they are evenly spread out.
