Membranes
The movement of molecules from a region of higher concentration to an area of lower concentration
diffusion
The thick fluid inside the cell membrane
cytoplasm
Powerhouse of the cell
Has two layers of membranes - the inner membrane is folded into ridges
mitochondria
Structure made of DNA and other molecules
chromosomes
He was known for grinding his own lenses to view tiny organisms
Leeuwenhoek
Diffusion and osmosis are this type of transport
passive transport
The parts of a cell that carry on many of the functions necessary to keep the cell alive
cytoplasmic organelles
Tiny organelles that direct the assembling of proteins
Ribosomes
Cellular structure that contains chromosomes
nucleus
This type of transport requires a cell to use its own energy
active transport
These types of membranes allow only certain molecules to pass through
selectively permeable
A series of folded membranes found in the cytoplasm of cells that allows substances to move from one part of the cell to another
Endoplasmic reticulum (ER)
Organelle which appears green
Inner membranes contain chlorophyll
Contains substances and structures needed to carry on photosynthesis
Chloroplasts
A medical doctor who examines human tissues, blood, and other body fluids to diagnose diseases and disorders
pathologist
The diffusion of water through a membrane
osmosis
These have one basic design, but there are many variations of that design in different types of cells
cell membranes
A structure in cells that stores various types of materials
vacuole
An organelle that contains enzymes to digest substances that are no longer needed
Lysosomes
A compact, roundish structure that functions as the control center for the cell
nucleus
This type of microscope uses two sets of lenses
compound light microscope
This contains two molecules (protein and lipid) and membrane flexibility
fluid mosaic model
This part of a cell is not found in all cells
cell wall
Organelle responsible for packaging substances that are then released from the cell
Golgi apparatus
The movement of substances through a membrane without the use of a cell's own energy
passive transport
These are generally shorter and are found in greater numbers on a cell than this
(two answers)
cilia - shorter
flagella - longer (long whiplike structures used in cellular movement)
