LS.3 Walk the Plank      

Which sequence lists the levels of organization in the human body from simplest to most complex?      
'cell - tissue - organ - organ system', 'organ system - tissue - cell - organ',  'tissue - cell - organ - organ system', 'organ - organ system - tissue - cell' 


A group of similar cells that work together to perform one function is-     
'a tissue', 'an organelle', 'an organ', 'an organ system' 

Which of these is not an organ?     
'cardiovascular system', 'heart', 'artery', 'vein'  

Your heart and blood vessels work together in your body. They form the- 
'cardiovascular system', 'skeletal system', 'nervous system', 'reproductive system'  

Five basic life functions of an organism are respiration, waste removal, growth, irritability and reproduction. Irritability in this context means-     
'responding to stimuli', 'showing emotion', 'thinking', 'interacting with the environment' 

Which are unicellular organisms?     
'bacteria', 'seaweed', 'tadpoles', 'mushrooms'  

Tissues group together to form-     
'organs', 'organ systems', 'organelles', 'organisms'  

Organs group together to form-     
'organ systems', 'tissues', 'organisms', 'organelles'  

Movement of substances in and out of cells is controlled by-     
'the cell membrane', 'the cell wall', 'the cytoplasm', ' the nucleus'


Which is NOT one of the ways materials move in and out of cells through the cell membrane?
'metabolism', 'diffusion', 'osmosis', 'active transport'  






Materials can move in and out of cells by means of diffusion, osmosis, or active transport. Which requires energy?     
'active transport', 'diffusion', 'osmosis', 'all of them'  

Blue dye dropped into a cup of water spreads slowly until all of the water is blue. This movement of material from an area of higher concentration to an area of lower concentration is an example of-   
'diffusion', 'osmosis', 'active transport', 'none of these'  

The diffusion of water or movement of water in and out of the cell is called-     
'osmosis', 'active transport', 'respiration', 'digestion' 

Osmosis and diffusion-     
'do not require energy', 'require energy', 'usually require energy', 'are forms of energy'  

Active transport- 
'requires energy', 'never requires energy', 'sometimes requires energy', 'is energy'  

Diffusion, osmosis, and active transport are three -    
'ways that substances move in and out of cells.', 'ways that cells can divide.', 'types of organisms.', 'ways that cells produce energy.' 

Which statement is NOT correct?     
'Bacteria are multicellular organisms.', 'Respiration, waste removal, growth, irritability, and reproduction are functions of organisms and of cells.', Mitosis is asexual cell division which produces two identical daughter cells.',   
'Organisms grow due to cell division rather than cell growth.'  

Which of these statements is supported by the cell theory?    
'Each cell in your body comes from a cell that has divided.', 'Only certain cells in your body divide to make new cells.', 'All organisms have multiple cells.', 'No organisms are composed of just one cell.'   

How do multicellular organisms grow?     
'Cells divide and make more cells.', 'Bacteria invade the cells.', 'Cells gets bigger.', 'Cells absorb energy from the Sun.'  

Which of these structures is made up of all of the others?     
'Organ systems', 'Organs', 'Tissues', 'Cells'
