After completing the ratings, read through the organelles and their functions.
Organelle
Function
Cell Membrane
Surrounds/protects the cell, regulates what goes into and out of the
cell
Nucleus and what it contains
Nucleus controls cell function, contains DNA and contains the
nucleolus
Nuclear envelope
Surrounds/protects and regulates what goes into and out of the
nucleus
Nuclear pore
small opening in the nuclear envelope where some items can
enter/exit the nucleus
Nucleolus
Contains the RNA – produces ribosomes
Cytoplasm
Surrounds the organelles and helps provide cellular support
Mitochondria
Power house of the cell, provides energy
Ribosomes
Makes proteins
Endoplasmic reticulum
(smooth and rough)
Both allow transport of materials within the cell, the rough ER has
ribosomes attached to it
Golgi apparatus
Packages items for export out of the cell
Centrioles
Used in animal cell reproduction (Mitosis)
Lysosomes
Produces digestive compounds that help rid the cell of waste
Vacuole
Stores water, smaller and more abundant in animal cells
Cytoskeleton and the
substructures of the
cytoskeleton
Provides the cell with additional support. Microfilament-small
component of the cytoskeleton and Microtubule-large component of
the cytoskeleton
Cell wall
Outside the membrane provides rigid support
Central vacuole
Larger and singular, holds water
Chloroplast
Converts sun light into chemical energy/photosynthesis
Leucoplast
Stores water and minerals
Chromoplast
Stores pigments other than chlorophyll to be used in photosynthesis
Plasmodesma
junction that allows cells to connect with each other and
communicate through the cell wall
Organizing the Words
In working with these organelles, you may have noticed some patterns or natural groups
that some of they might fit into. Put the organelles into at least three different groups. (You
can use the same one multiple times.) Then, give each group a label that describes how
the organelles go together. In creating your groups, don’t be afraid to look beyond the
obvious.
Select three organelles from the vocabulary list and arrange them in the triangle. Explain
the relationship between each pair of words by writing along each line.
Finally, use the organelle list to label the pictures below to give you a visual representation of
the organelle. There is a plant cell and an animal cell, so you may not find all the organelles
on each picture. You can try the following websites to help you find this information:
