cell structure & function

Question 1

cell theory

Answer 1

• all living things are made of 1+ cells
• cells are the basic unit of structure & function in living things, they carry out life functions
•cells come from other cells

Question 2

exceptions to the cell theory

Answer 2

1) scientists argue viruses are living because they contain a genetic code but are not made of cells

2) scientists argue mitochondria & chloroplasts can be considered living bc they contain their own DNA & reproduce but aren’t made of cells

3) scientists argue the first cell must have come from something other than a pre existing cell

Question 3

prokaryote

Answer 3

• heat & salt lovers
•methane makers
•anaerobic (can live without oxygen)
•do not cause disease (non-pathogenic)

Question 4

eukaryote

Answer 4

•more common
•disease causing (pathogens)
•mainly aerobic (need oxygen)

Question 5

unicellular organisms

Answer 5

consist of only 1 cell living independently

are ably to carry out all life functions

Question 6

multicellular organisms

Answer 6

composed of more than one cell

cells work together to carry out life functions

cells are specialized
