ICan2Ed, Inc.
All cells of the plant kingdom have a nucleus
as one of the most important organelles (little
organs). The second largest organelle of the
plant cell is the n______.
The large, usually round, organelle of a cell is
the n______.
DNA, the genetic material that controls the
activity of the cell, is located in the n______.
The nucleus is a membraneenclosed o________ found in animal and plant
kingdom (eukaryotic) cells.
1
Biology breaks cell types into eukaryotic
(those with a defined n______)
and prokaryotic (those with no defined
n______).
The nucleus is not always in the center of the
cell. The big dark spot somewhere in
the cytoplasm is the n______.
The membrane-bound organelle around which
other parts are grouped or gathered is the
n_______.
All cells of the plant kingdom have a nucleus

plant cell is the n______.
DNA, the genetic material that controls the
activity of the cell, is located in the n______.
2
Nuclear envelope is another name for the
nuclear m_______ of the nucleus.
The outer cover of the nucleus is called the
n______ m_______ or the n______
e_________.
A nuclear m________, also known as the
nuclear e________, is a double lipid bilayer
that encloses the genetic material (DNA) in
eukaryotic cells.
The nuclear membrane also serves as a
physical barrier, separating the genetic contents
of the nucleus (______) from the cytoplasm.

activity of the cell, is located in the n______.
Nuclear envelope is another name for the
nuclear m_______ of the nucleus.
The outer cover of the nucleus is called the
n______ m_______ or the n______
e_________.
The nucleus is filled with a fluid called
nucleoplasm. The organelles of the nucleus
float in the fluid known as n________.
Like cytoplasm, n______ allows nutrient
molecules to move to the organelles.
4
Like cytoplasm, the nucleoplasm supports and
protects the o_______ of the n______.
Nutrients and fluids move into and out of the
nucleus through nuclear pores. The nucleus
transports substances through the n_____
p_____.
Substances and waste products are transported
between the cytoplasm of the cell and the
nucleoplasm of the nucleus through the
n______ p_____.

molecules to move to the organelles.
Substances and waste products are transported
between the cytoplasm of the cell and the
nucleoplasm of the nucleus through the
n______ p_____.
The largest organelle floating in the nucleus is
the nucleolus. The round granular structure
within the nucleus of a cell is the n________.
6
A non-membrane bound structure composed of
proteins and nucleic acids found within the
nucleus of cells is called the n________.
A small rounded body within a nucleus that
contains RNA and proteins and is involved in
the production of ribosomes is known as the
n______.
The organelle of the nucleus that plays an
important part in the synthesis of ribonucleic
acid (RNA) and protein is the n_______.

Chromatin is the combination of DNA and
proteins that make up the contents of the
nucleus of a cell. The contents in the nucleus
that forms the DNA is the c______.
The coiled fibers that form the rod-like
chromosomes of DNA are the c_______.

The mass of genetic material composed of
DNA and proteins that condense to form
chromosomes is the c______.
The substance of a cell nucleus, consisting of
DNA, RNA, and various proteins, that forms
chromosomes during cell division is known as
c______.
DNA winds itself around proteins
called histones, thereby forming a complex
known as c_______.
