|
Bacteria
|
the smallest organisms on Earth; they are one-celled organisms.
|
|
|
Cytoplasm
|
a gelatinlike substance inside of the cell. It is mostly water.
|
|
|
Organ System
|
a group of organs that work together to do a certain job.
|
|
|
Organs
|
different types of tissues working together can form a structure
|
|
|
Mitochondria
|
(except bacteria cells) converts food energy into a form that cell can use Cellular respiration takes place inside a mitochondrion.
|
|
|
Photosynthesis
|
a process by which many types of bacteria make food.
|
|
|
Vacuoles
|
where food and water is stored.
|
|
|
Cell wall
|
the structure outside the cell membrane. It helps support and protects the cell.
|
|
|
Chloroplasts
|
captures energy from sunlight and uses it to convert carbon dioxide and water into food.
|
|
|
nucleus
|
the hereditary material in the organelles. The nucleus controls most of the cells activities.
|
|
|
organelles
|
specialized cell parts that can move around in the cytoplasm and perform activities that are necessary for life. All cells except bacteria cells contain organelles.
|
|
|
cell membrane
|
a flexible structure that holds the cell together.
|
|
|
tissue
|
groups of similar cells that all do the same sort of work.
|
|
|
Nerve Cell
|
characteristic of an organism that helps it to survive in its environment
|
|
|
function
|
what a cell's shape and size is related to
|
|
|
organism
|
a group of organ systems working together
|
|
|
cell
|
the smallest living unit in the body.
|
|
|
organ
|
two or more types of tissue working together
|
|
|
bone cell
|
cell surrounded by calcium and phosphorous.
|
|
|
fat cell
|
can store so much fat that the nucleus gets pushed against the cell membrane.
|
|
|
nerve cell
|
long and with many branches that receive and deliver messages
|
|
|
muscle cells
|
usually long and have many fibers that can contract and relax
|
|
|
skin cells
|
mostly flat and close together. They form a protective layer for the body.
|
|
|
nucleus
|
where the hereditary material of the cell is held, except in bacteria.
|
|
|
Vacuoles
|
a place for storage inside the cell
|
|
|
Cell wall
|
the outer support and protective coating of a plant cell.
|
|
|
mitochondria
|
the energy producing units of a cell
|
|
|
photosynthesis
|
the process of capturing energy and converting it to food in the chloroplasts.
|
|
|
organelle
|
performs activities necessary for the cell's life.
|
|
|
photosynthesis
|
process of making energy in plants
|
