The mighty cell
What part of the cell is made up of 2 layers of phospholipids with pores?
cell membrane
Which organelles clean up cell debris via phagocytosis?
lysosomes
This involves the movement of water from areas of higher concentration to areas of lower concentration
osmosis
This occurs when water and dissolves substances cross the cell membrane due to a difference in pressure, rather than concentration
filtration
What is considered the "powerhouse" of the cell?
mitochondria
What is considered the "brain" of the cell, as it contains DNA?
the nucleus
Which organelle makes protein?
ribosomes
What is the term used to describe a solution that has less solutes than the cell?
hypotonic
What type of solution can cause cytolysis?
hypotonic
Active transport mechanisms require____________as fuel to move substances from areas of lower concentration to areas of higher concentration
ATP
Name the thread-like structures (found in the nucleus) that contain DNA and proteins
chromatin
What makes rough endoplasmic reticulum rough?
ribosomes
What is the term for a solution that has more solutes than the cell?
hypertonic
What is considered the "resting" phase of mitosis?
interphase
What is the name of the gel-like substance that is found inside the cell, but outside the nucleus?
cytoplasm
This stack of smooth membrane sacs receives proteins from the endoplastmic reticulum and repackages the proteins for export out of the cell.
Golgi apparatus
Movement of a substance (like sodium) from an area of high concentration to an area of low concentration is called:
diffusion
This term is used to describe a solution that has an equal concentration of solute as the cell
isotonic
During which stage of mitosis does the parent cell pinch in two, forming 2 new cells?
telophase
Which type of organelle plays a key role in mitosis?
centrioles
Name 3 types of passive transport mechanisms
diffusion, facilitated diffusion, osmosis, filtration
Which type of diffusion requires a "helper" molecule to help carry a substance across the cell membrane?
facilitated diffusion
What happens to the cell when a hypertonic IV solution is administered?
it shrinks (crenates)
What is the term for when a cell shrinks?
crenation
Name the 2 different types of endocytosis
phagocytosis, pinocytosis
