Cell Theory
This scientist first described living cells as seen through a simple microscope.
Who is Anton van Leeuwenhoek?
This structure surrounds and protects the nucleus.
What is the nuclear membrane?
This pigment gives plants their green color.
What is chlorophyll?
The plasma membrane is described as this because phospholipids and proteins can move freely within it.
What is a fluid mosaic?
A prokaryotic cell lacks this membrane-bound structure.
What is a nucleus?
This part of the microscope magnifies the specimen by aiming light or electrons.
What are lenses or electromagnets?
In a cell, these structures are responsible for protein synthesis.
What are ribosomes?
Unlike animal cells, plant cells have this rigid outer structure.
What is a cell wall?
This type of transport requires no energy and moves substances down their concentration gradient.
What is passive transport?
These cells have specialized structures like the mitochondria and nucleus.
What are eukaryotic cells?
This theory states that all living organisms are made of cells and that all cells come from preexisting cells.
What is the cell theory?
These folded systems of membranes form interconnected compartments in a cell.
What is the endoplasmic reticulum?
In plants, these structures convert light energy into chemical energy.
What are chloroplasts?
This process uses energy to bring materials into the cell by engulfing them.
What is endocytosis?
This type of organism has no true nucleus.
What is a prokaryote?
This type of microscope provides higher magnification than a light microscope.
What is an electron microscope?
The name of the cell structure that contains digestive enzymes.
What are lysosomes?
This is the large storage compartment in plant cells but not in animal cells.
What is the vacuole?
When a cell is placed in saltwater, water leaves the cell through this process.
What is osmosis?
In prokaryotic cells, this structure contains the genetic material.
What is the nucleoid?
The scientist who concluded that all plants are made of living cells.
Who is Matthias Schleiden?
These short, hair-like projections help in cell locomotion.
What are cilia?
This structure forms the framework of both plant and animal cells.
What is the cytoskeleton?
The movement of materials into and out of the cell is controlled by this structure.
What is the plasma membrane?
The scientist who identified and named the cell.
Who is Robert Hooke?
