• a fungus

• a prokaryote

Which of these is NOT a component of the cell theory?

• all living things are made of cells

• cells form through spontaneous generation

• cells are the basic functional structure of life

• cells come from preexisting cells

"Active transport" is when a cell:

• absorbs materials from Low to High concentrations without energy

• absorbs materials from High to Low concentrations without energy

• forces materials from Low to High concentrations using energy

• does nothing

Where in a cell is this structure found, and what is its purpose?

• around the nucleus; protein production

• around the cell; protection and transport

• near the nucleus; package molecules for transport

• in plant cells only; photosynthesis

• golgi apparatus and vessicles; make and process energy

• cell membrane and cell wall; package molecules for transport

• ribosomes, rough and smooth ER; manufacture proteins
