1. An animal’s cell city limits or outer layer; surrounds an animal cell
2. The cells’ transportation system; similar to roads
4. The part of the cell that packs and carries; similar to the post office
5. The cell’s powerhouse; supplies most of the energy for cells
6. Cells were first discovered because of the invention of this instrument

UNIT STUDY GUIDE FOR CELLS
Be able to explain, define and/or apply the following words and concepts.

Word
Explanation
System
A combination of things or parts that make a whole
Structure
Parts of a system
Function
Refers to the job or purpose of the structure
Cell
Basic unit of life, smallest part of living things
Organism
A living thing
Cell Theory
A general statement in biology that all living things consist
of cells, which came from previously existing cells
Hooke had discovered dead plant cells in a piece of cork
Robert Hook
with a microscope that he created
Organelles
Tiny structures that make up the insides of a cell
Five Organelles to Know:
Cell Wall
The firm nonliving layer that surrounds and supports most
plant cells.
Cell Membrane
The outside layer surrounding the contents of a cell, it
allows materials in and out of the cell (like a fence). It is
semipermeable (see below).
Nucleus
The nucleus controls many of the functions of the cell, like
a command center
Nuclear membrane
The outside layer of the nucleus, protects the genetic
materials inside the nucleus and allows materials in and
out of the nucleus.
Use energy from the sun to make food for the plant
Chloroplasts
through photosynthesis, by containing the chlorophyll
needed for the chemical reaction of photosynthesis.
Differentiate between
Plant cells have a cell wall (for support), chloroplasts
plant and animal cells
(which contain the chlorophyll needed for
photosynthesis), which are not found within animal cells
Membrane allowing certain substances to pass through it
Semipermeable
but not others
Other organelles for
enrichment:
Vacuoles
Mitochondria
Lysosomes
Golgi bodies
Storage bubbles found in cells
The cell’s powerhouse; supplies most of the energy for
cells
The cell’s recycler; breaks down worn out products to be
used by the cell
The part of the cell that packs and carries
