Organisms made up of one cell
Unicellular
A large group of one-celled organisms that sometimes cause disease
Bacteria
Organisms made up of many cells
Multicellular
A cell in which the genetic material is enclosed with a nucleus, surrounded by its own membrane
Eukaryotic
Different tissues working together to preform a particular function
Organ
A cell that lacks a nucleus and other organelles, with DNA that is not organized into chromosomes
Prokaryotic
A tough outer covering that lies just outside the cell membrane
Cell Wall
Organelles that release energy by using oxygen to break down sugars
Mitochhondria
A thick, gelatin-like material contained within the cell membrane
Cytoplasm
Any part of a cell that is enclosed by a membrane
Organelle
Organelles in which the energy from sunlight is used to make sugar
Chloroplast
A group of similar cells that are organized to do a specific job
Tissue
An instrument which makes and object appear bigger than it is.
Microscope
A protective covering that encloses the whole cell
Cell Membrane
The structure in a eukaryotic cell that contains the genetic material a cell needs to reproduce and function
Nucleus
Specific cells perform specific functions
Specialization
The movement of water through a membrane from an area of high concentration to an area of low concentration
Osmosis
The process of using energy to move materials through a membrane
Active Transport
The movement of materials through a membrane without any input of energy
Passive Transport
Something that can be passed through.Especially by liquids and gases.
Permeable
The tendency of a substance to move from an area of higher concentration to an area of lower concentration
Diffusion
Is a process for moving items that are outside of the cell into the cytoplasm of the cell
Endosytosis
A process for moving items from the cytoplasm of the cell to the outside
Exocytosis
When the concentration of the dissolved particle is greater inside the cell than it is outside the cell
Hypotonic
When the concentration of the dissolved particle is greater outside the cell than it is inside the cell
Hypertonic
The process of maintaining balance inside the cell
Homeostasis
The process of converting light energy to chemical energy and storing it in the bonds of sugar
Photosynthesis
