This scientist first used the term "cells" after observing tiny empty chambers in a wine cork.
What is Robert Hooke
This organelle houses the cell's DNA and acts as the control center.
What is the nucleus
Another name for the cell membrane
What is phospholipid bilayer
The overall purpose of cell transport is to maintain this state of balance in the cell.
What is homeostasis
This type of passive transport uses protein channels to help molecules cross the membrane, but still requires no energy and goes from high to low concentration.
What is facilitated diffusion
This scientist used a microscope to observe pond water and saw small animals swimming around.
What is Anton van Leeuwenhoek?
All cells contain these three things
What is cytoplasm, cell membrane, ribosomes
Phospholipids have this type of head and this type of tail that help hold the membrane together.
What is a hydrophilic head and a hydrophobic tail
This type of transport requires NO energy and moves molecules from high to low concentration.
What is passive transport
This is the movement of water across a semipermeable membrane
What is osmosis
These cells are much larger, contain organelles, have DNA housed in a nucleus, and can be either unicellular or multicellular.
What are Eukaryotes
In large organisms, cells have these sites that chemical signals bind to in order to receive messages on what he cell should do
What are receptors
These structures embedded in the cell membrane act as tunnels
What are protein channels
This is the movement of molecules across a membrane from an area of high concentration to low concentration until equilibrium is reached.
What is diffusion (or simple diffusion)
This type of transport requires ENERGY and moves materials from LOW to HIGH concentration against the concentration gradient.
What is active transport
This type of cell is always unicellular, has DNA that is free-floating (not in a nucleus), and includes bacteria.
What is Prokaryotic
While animal cells contain several organelles, they do not contain these organelles found in plant cells
What is cell wall, chloroplasts, central vacuole
Water is unable to pass through the cell membrane due to this
What are the hydrophobic tails of the phospholipids
When large molecules or charged molecules cannot pass through the membrane on their own, they use these protein structures to cross.
What are protein channels
This process uses vesicles or vacuoles to bring large molecules or clumps of material INTO the cell; white blood cells use a specific type of this to destroy foreign cells.
What is endocytosis
These are the three parts of the Cell Theory established in 1839.
What are: all living things are made of cells, cells are the basic unit of structure and function, and new cells come from existing cells?
In multicellular organisms, the levels of organization consist of
What is cell, tissue, organ, organ system, organism
Draw a phospholipid and label it
hydrophilic head, hydrophobic tail
In the image, the cell was placed in this type of solution
What is hypertonic
In the image, the cells have been placed in this type of solution
What is hypotonic
