Question

Some botanists argue that the entire plant should be considered as a single unit rather than a composite of many individual cells. Which of the following cellular structures cannot be used to support this view?

a. cell wall

b. cell membrane

c. cytosol

d. tonoplast

e. symplast

please help :) an explanation would be great, thanks!

Answer 1

I know that it isn't the symplast.  I've been looking for the reason but can't find it.  The tonoplast is a membrane enclosing the central vacuole so that doesn't really mean they are independent.  The cell wall could suggest that they are not independent as each cell is connected by plasmodesmata to the cytoplasm of adjacent cells.
