Cell Theory
The cell theory states that all living things are made of what?
Cells
The clean up crew of the cell
lysosomes
This regulates what enters and leaves the cell and also helps with support and protection, found in all cells
Cell membrane
The movement of water through a selectively permeable membrane
osmosis
Many similar __ make up tissues
cells
The cell theory states that new cells come from where?
Existing Cells
This organelle makes proteins
ribosomes
Large saclike storage area in a cell
vacuole
Moving from high concentration to low concentration
diffusion
Many __ working together make up organs
tissues
The cell theory states that cells are the basic unit of what and what in living things?
structure and function
This is where ribosomes are made:
Nucleolus
Modifies, sorts, and packages proteins
Golgi Apparatus
What is the major difference between active and passive transport?
Passive doesn’t require energy and active does
Stomach, heart, and brain are all examples of these:
organs
What is the major difference between prokaryotes and eukaryotes?
Pro: no nucleus
Eu: yes nucleus
This organelle helps to make parts of the cell membrane and to detoxify drugs
Smooth ER
Which 2 organelles function in energy conversion?
mitochondria and chloroplasts
Type of diffusion in which molecules pass through membrane channels
facilitated diffusion
Many organs working together create an:
organ system
What 2-3 things does every cell contain no matter what type it is?
DNA, cell membrane, cytoplasm
This organelle is only found in animal cells, is made from the same protein filaments that make up the cytoskeleton and helps with cell division
Centrioles
A complex of DNA bound to proteins in the nucleus
chromatin
Taking material into the cell by using infoldings of the cell membrane
Endocytosis
Name the 4 levels of organization in order from MOST complex to LEAST complex
organ system, organ, tissue, cell
