Chapter 4 Flashcards
A thin coat of phospholipids that surrounds the cell
Cell Membrane
This thing consists of
All organisms consist of one or more cells.
Cells are alive and the site of all life processes.
All cells come from pre-existing cells.
Cell Theory
the material inside the cell membrane
Cytoplasm
Living things with eukaryotic cells are
Eukaryote
cells that contain a nucleus
Eukaryotic Cell
a structure enclosed by a membrane that contains most of the cell’s DNA
Nucleus
a structure composed of two or more types of tissue that work together to do a specific task.
Organ
any structure inside a cell that is enclosed by a membrane.
Organelle
a group of organs that work together to do the same job
Organ System
Organisms with prokaryotic cells
Prokaryote
Cells that lack a nucleus
Prokaryotic Cell
structures in the cytoplasm where proteins are made
Ribosome
a group of cells of the same kind that performs the same function
Tissue
packages energy in smaller amounts that cells can use.
ATP
a rigid layer that surrounds the cell membrane of a plant cell
Cell Wall
Most plants have a
Central Vacuole
organelles that are found only in animal cells
Centriole
A structure of Crisscrossing the cytoplasm
Cytoskeleton
organelle that helps make and transport proteins and lipids
ER
a large organelle that sends proteins and lipids where they need to go
Golgi apparatus
organelle that recycles unneeded molecules
Lysosome
organelle that makes energy available to the cell
Mitchondrion
Both are sac-like organelles
Vacuole and Vesicles
