18. Photosynthesis
• Write the chemical equation for
photosynthesis. Under each component
draw an illustration to help you remember
this equation.
19. Cellular Respiration
• Cellular respiration occurs in most
____________ _____________.
• During cellular respiration, ____________ (such
as glucose) is broken down into ________ and
____________ and _________ is released.
• In animals, most of the energy released helps
maintain __________________.
• Some of the energy is used to form __________
(energy that fuels cell activities).
20. Cellular respiration
• Write the chemical equation for cellular
respiration. Under each component draw
an illustration to help you remember the
equation.
21. Photosynthesis vs.
Cellular Respiration
• Photosynthesis transforms energy from the
____________ into glucose. During
photosynthesis, cells use __________ to make
glucose, and the cells release _____________.
• During cellular respiration, cells use
____________ to break down _________ and
release __________ and _________.
• Each process makes the materials that are
needed for the other process to occur
elsewhere.
22. Fermentation
• Write the definition of fermentation.
• One kind of fermentation happens in your
muscles and produces ________ _______.
• The buildup of _________ _________ contributes to muscle fatigue
and causes a burning sensation.
• This kind of fermentation also happens in the muscle cells of other
animals and in some ___________ and _____________.
• Another type of fermentation occurs in some
types of ______________ and ____________.
23. ALL LIVING THINGS GROW
AND DEVELOP,REPRODUCE, AND
HAVE DNA
Cell Cycle and Cell Division
• Write a definition of the cell cycle.
• The cell cycle begins when the cell is ______________.
• Then cell cycle ends when the cell ______________.
• Before a cell divides, it must make a copy of its
___________ (hereditary material that controls
all cell activities, including the making of new
cells).
• Copying __________ ensures that each new
cell will be an exact copy of its parent cell.
24. Cell Division in Prokaryotes
•
Write a definition of prokaryotic cell.
•
Draw an illustration of a typical prokaryotic cell.
•
What organisms contain prokaryotic cells?
•
Define binary fission.
•
Binary fission results in two cells that each contain one copy of
________________________.
25. Illustration of Binary fission
26. ALL LIVING THINGS HAVE
DNA Eukaryotic cells and DNA
• The chromosomes in eukaryotic cells
contain more __________ than
prokaryotic cells do.
• The number of chromosomes depends on
the organism.
– Example: Fruit flies have _________ chromosomes, potatoes
have ____________ chromosomes, and humans have
___________ chromosomes.
27. Illustration of the human
chromosome
• (You must show all 23 pairs of
chromosomes)
28. Eukaryotic Cell Cycle
• There are three stages:
– ____________- the cell grows and copies its
organelles and chromosomes.
– ____________- a process of cell division that
forms two new nuclei, each of which has the
same number of chromosomes
– ____________- the cytoplasm begins to
divide and two identical cells are formed.
29. The cell cycle
• Draw, label, and write a caption for the
three stages of a cell’s cycle including the
four phases of mitosis. There are six total.
