Parts of A Cell
Writing Across Curriculum
Activity
Grade 5
 The
learner will be able to draw
and label the fundamental
structures of animal and plant
cells .
At the end of this activity you will:
 Choose
a part of the cell and
write a paragraph about it.
What are cells?
Your body is divided into tiny sections
called cells.
 The cell is one of the most basic units
of life.
 Cells are group together in collections
called tissues.

Cells
 There
are cells that are organisms
onto themselves, such as
microscopic amoeba and bacteria
cells.
 There are cells that only function
when part of a larger organism,
such as the cells that make up your
body.

Cells
 Most
cells are too small to be
observed with the naked eye.
 The structure of cells can mostly
only be studied with the aid of an
optical microscope and specialized
color techniques.
Cell Areas
All
cells have three main
areas: the cell membrane,
the cytoplasm, and the
nucleus.
Cell Membrane
The cell membrane surrounds the
cytoplasm of the cell.
 It acts as a boundary layer to contain
the cytoplasm (fluid in cell).
 It allows water, oxygen, and other
materials to pass in and out of cells.

Cytoplasm
Cytoplasm is the material between the
cell’s nucleus and the cell membrane.
 It fills the entire cell.
 It contains a large variety of organelles
and nutrients.
 The cytoplasm consists of an outer
ectoplasm and an inner endoplasm.
 It stores nutrients.

Nucleus
 The
nucleus is the cell’s
command center.
 The cell nucleus contains the
cell's DNA, the genetic code.
Mitochondria
The
mitochondria provide
the energy for the cell.
Organelles
Organelles are small structures that help
carry out the day-to-day operations of the
cell.
Types of organelles:
 Ribosome are organelles which participate
in protein synthesis.
 Mitochondrion, the power plants of the cell,
are organelles that produce energy.
 Lysosomes are organelles that contain
enzymes that aid in the digestion.
