Which historical event most directly contributed to the development of the cell theory?
The discovery and classification of thousands of species of organisms.
The development of microscopes and higher powered lenses.
The development of theories of natural selection on evolution of organisms.
The discovery that DNA is the genetic material
The smallest unit that can carry out ALL activities associated with life is —
a tissue
the cell
the atom
the organelle
According to the cell theory —
all organisms are composed of tissues
animals are composed of cells, but plants are not
the smallest unit of life is an atom
All living things are made up of cells
Who was one of the first people to observe living organisms using a microscope?
Anton Van Leeuwenhoek
Rudolf Virchow
Charles Darwin
Matthias Schleiden
Robert Hooke was known for which of the following?
Proposed that cells reproduce through cell division.
Noted that all plants are made from cells
Observed that cells have a dark central body called a nucleus
Was the first to see cells and gave them their name
Not until the contributions of which scientist did the public begin to understand the connection between the formation of new cells and other living cells? “Cells arise from other cells.”
Virchow
Schleiden
Schwann
Leeuwenhoek
Matthias Schleiden was a botanist who first noted -?
Both plants and animals are made from prokaryotic cells
All plants are made up of cells
Cork cells contained many small empty compartments
Animal tissues are composed of cells
To which scientist is attributed the idea that ALL living things are made up of cells? Hint: He first said that all animals are made of cells.
Leeuwenhoek
Schleiden
Schwann
Hooke
When the German biologist Theodor Schwann expanded the cell theory to include not only plants but also animals, he was including which two areas of study?
Horticulture and Histology
Microbiology and Limnology
Botany and Zoology
Entymology and Anatomy
Which of these supports the cell theory as it is stated today?
All organisms are composed of more than one cell.
Cells must contain a nucleus.
Not all cells are alive.
New cells are produced by division of existing cells.
What characteristic do all living things share?
They reproduce by mitosis.
They are made up of many parts.
They contain DNA.
They need oxygen to survive.
The main difference between prokaryotic and eukaryotic cells is that
eukaryotic cells have a smaller cell nucleus
prokaryotic cells are always much larger
prokaryotic cells do not have a plasma membrane
eukaryotic cells have a more advanced cellular organization
A student wants to view cells under the compound microscope at a total magnification of 400x. If the eyepiece if 10x, which of the following objective lenses should be used?
10X
40X
100X
4X
