CELLS
Cell Parts and Their Functions
 Nucleus-“control
center” - controls the cell’s activities;
contains DNA in Chromosomes
 Cell
Membrane- “gatekeeper”- surrounds the cell and
regulates what goes in and out of the cell
 Cell
Wall-in plant cells, protects and supports the cell,
 Mitochondria-
“powerhouse” – uses oxygen to
convert energy stored in food into energy the cell can
use – found in both Plant and Animal cells
Cell Parts and Their Functions
 Vacuoles
– “storage sacks” – stores food, water
and wastes; larger in plant cells (sometimes just
one large vacuole in plant cells)
 Chloroplasts-
“Food Factories” – Uses sunlight
energy to convert carbon dioxide and water
into glucose (food) in plant cells. Oxygen is a
waste product.
 Cytoplasm
– jellylike substance that fills the cell
between the membrane and the nucleus; cell
organelles are here.

Comparing Mitochondria and
Chloroplasts
Mitochondria - “Powerhouses”
 Uses
oxygen to convert energy
stored in glucose (food) into
energy (ATP) that the cell needs
to function in a process called
respiration.
 Found
cells.
 Water
in both plant and animal
and carbon dioxide are
given off as waste products.
