Organelles within the Cell
Brian S. McNeel
Introduction
• The cell is the smallest unit of life.
• Organelles are a structure within the cell
that help it function.
• There are many type of organelles that
we will talk about their function and
description.
Name and Function
• Nucleus: the heart of the cell that
contains your entire genetic make up for
that particular cell.
• Nucleolus: the center of the nucleus that
aids in the production of ribosome's.
• Nuclear Membrane: a double membrane
that encloses the nucleus and its
contents.
• Mitochondria: where ATP is made, and it
is also the site of cellular respiration.
Cont.
• Golgi Apparatus: where synthesis, sorting, and
releasing of cell products takes place.
• Microfilaments: The thinnest type of the
fiber’s that acts alone to cause cell
contraction.
• Plasma Membrane: the wall that protects the
entire cell from invaders and lets out waste
and other materials.
• Lysosome: contains enzymes in the membrane
sac that are used to digest macromolecules.
Cont.
• Microtubules: the thickest of the fibers that
shape and support the cell, but also provide
tracks for movement of the organelles.
• Chromatin: little strands of DNA and proteins
within the nucleus; at certain times you can
see the chromatin.
• Cytoplasm: a liquid type jelly where the
organelles are suspended, it is everything in
between the nucleus and the plasma
membrane.
• Endoplasmic Reticulum: a network of sacs and
tubes that are active in metabolic synthetic
process.
