Science Photosynthesis and Cellular Respiration
Terms in this set (25)
A plant cell takes in SUNLIGHT, CARBON
DIOXIDE AND WATER and uses it to create
energy and to make glucose and oxygen.
What materials does a plant take in during
What Materials are considered products of
Where does photosynthesis take place?
An Animal cell takes in OXYGEN AND
GLUCOSE and uses it to make energy and to
release carbon dioxide and water
What materials are taken in during cellular
What materials are considered products of
Where does cellular respiration take place?
How does Carbon Dioxide enter a leaf prior to
Through the Stomata
Why do consumers (heterotrophs) and
producers (autotrophs) need each other?
Heterotrophs require the glucose and
oxygen that autotrophs create. Autotrophs
need the carbon dioxide to make food for
itself that Heterotrophs produce (create)
What gases are kept at consistent levels in the
atmosphere because of these processes?
Cells release energy from food without using
A form of fermentation (breaking down glucose
without oxygen) where lactic acid builds up in
muscles, causing muscles to feel weak and
When a cell grows, develops and prepares for
division into to new "daughter" cells. During
this process chromosomes are replicated and
doubled (cells have 92 chromosomes instead
When does replication occur during the cell
cycle? (copy DNA)
What is copied during replication?
The DNA strands in chromosomes
The cell's nucleus divides and two new nuclei
and one set of DNA is distributed into each
new daughter cell
What forms around the new chromatids during
In animals, the cellular membrane pinches in
to create two separate daughter cells
In plant cells, a cell plate grows between the
two cells to create two daughter cells
Cell Grows and Develops
Cell spends the majority of its time.
Chromosomes condense in the nucleus
Spindle Fibers form between the Centrioles
Each Chromosome attaches to the spindle
Chromosomes line up in the center of the cell
The center of the Chromosomes split
(centromeres) and are pulled to opposite
ends of the cell.
Cell starts to stretch out
The nuclear membrane develops around the
new sets of Chromosomes
Cells are stretched apart and reading to split
Two daughter cells are formed. Two new
cells split apart.
