What is a central vacuole?

100

The process by which a cell engulfs large particles.

What is phagocytosis?

100

A component of the plasma membrane that plays an important role in cell-to-cell recognition.

What is a glycoprotein?

100

This mathematical relationship explains why cells must remain small, as it decreases when cell size increases, limiting the efficiency of nutrient uptake and waste removal across the cell membrane.

What is SA:V ratio?

What is dilute the solutes? 

200

Fundamental difference between prokaryotic and eukaryotic cells. 

What is the absence of a nucleus?

Molecules moving in what direction causes a cell to use active transport. 

What is from low -> high?

200

This plasma membrane is made up of two layers of phospholipids. Phospholipids are made up of two parts, a hydrophilic head and a hydrophobic tail. What is this phenomenon called?

What is amphipathic? 

200

Calculate the SA:V ratio for a spherical cell with a radius of 5μm. 

4/3 * pi * r3

200

The type of solution a cell is placed in that bursts animal cells but leaves plant cells functioning normally. 

What is hypotonic? 

300

An aspect of the mitochondria that allows it to be highly efficient at glycolysis (energy production). 

What is compartmentalization (High SA:V ratio)?
300

A type of transport that would move a small, uncharged, polar molecule. 

What is simple diffusion? 

300

A component of phospholipids that allows for membrane stability across a variety of temperatures.

What are the double bonds (kinks) in the phospholipid tails?

Water can enter the cell in two ways. Name both ways water can enter a cell. 

What is simple diffusion through the membrane & via facilitated diffusion through an aquaporin? 

400

The inside of a channel protein is _______ to allow substances to move through the channel.

What is hydrophilic?

400

A higher SA:V ratio indicates this about the cell.

What is efficent exchange of materials across the plasma membrane?
