CELL STRUCTURE AND FUNCTION
KEY CONCEPTS
 Cell structure is related to cell function.
 Cell parts are interdependent.
 Cells take in nutrients to grow, divide, and make needed
materials.

LEARNING TARGETS
I CAN….
 Obtain, evaluate, and communicate information to
describe how cell structures, cells, tissues, organs,
and organ systems interact to maintain the basic
needs of organisms.
 Develop a model and construct an explanation of how
cell structures (specifically the nucleus, cytoplasm,
cell membrane, cell wall, chloroplasts, lysosome, and
mitochondria) contribute to the function of the cell
as a system in obtaining nutrients in order to grow,
reproduce, make needed materials, and process
waste.
autotroph
Definition: an organism that is able to form
nutritional organic substances from simple
inorganic substances such as carbon dioxide.
•Examples: green plants, algae, iron bacteria
heterotroph
Definition: an organism deriving its nutritional
requirements from complex organic
substances
•Examples: herbivores, omnivores,
carnivores, fungi, protozoa
chloroplast
Definition: an organelle found in plant and
algae cells where photosynthesis occurs
•Examples: contains chlorophyll, responsible
for enabling photosynthesis
Mitochondria
Definition: in eukaryotic cells, the organelle
that is the site of cellular respiration, which
releases energy for use by the cell.
•Examples: energy supply for the cell.
ATP
Definition: ATP stands for adenosine triphosphate. It is a molecule
found in the cells of living organisms. It is said to be very important
because it transports the energy necessary for all cellular metabolic
activities.
•Examples: One example of ATP being used
in intracellular signaling is the release of
calcium for cellular processes in the brain.
Reactants
Definition: A substance that
participates in a chemical reaction.
•Examples: The reactants of a lit candle
involve the physical properties of the
chemicals oxygen, carbon and hydrogen
Products
Definition: A substance that forms
in a chemical reaction
•Examples: The reactants for photosynthesis
are light energy, water, carbon dioxide and
chlorophyll, while the products are glucose
Glucose
Definition: a simple sugar which is an
important energy source in living organisms
and is a component of many carbohydrates.
•Examples: Glucose, which is actually a
sugar, feeds the plant. There are many uses
of glucose in plants. Glucose helps plants
