Chapter 7 Flashcards
In many cells, the structure that controls the cell’s activities is the
nucleus
Despite differences in size and shape, at some point all cells have DNA and a
cell membrane
What distinguishes a eukaryotic cell from a prokaryotic cell is the presence of
a nucleus
In eukaryotic cells, chromosomes carrying genetic information are found in the
nucleus
The organelles that break down lipids, carbohydrates, and proteins into small molecules that can be used by the cell are called
nucleic acids
Cell membranes consist mainly of
lysosomes
The movement of water molecules across a selectively permeable membrane is known as
osmosis
A substance that moves by passive transport tends to move
from areas high to low
Which one of the following is not part of the cell theory?
cells never die
