obtaining energy from the plant (food).The illustration must include captions

17.PhotosynthesisMakes _________

• ______________ capture energy from the sun and change it into food.

18.PhotosynthesisMakes _________

• Write the chemical equation (pg 94) for photosynthesis. Under each component draw an illustration to help you remember this equation.

19.Cellular Respiration Makes _________

• Most ____________ _____________ obtain energy through cellular respiration.

• 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 Makes _________

• Write the chemical equation for cellular respiration (pg 95). Under each component draw an illustration to help you remember the equation.

21. The CONNECTION between Photosynthesis &

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. FermentationMakes _________

• 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

DNACell 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 (review).

• Draw an illustration of a typical prokaryotic cell (review).

• What is an example of a prokaryote (review)?

• What does binary fission mean (pg 98).

• Binary fission results in two cells that each contain one copy of the circle of _____________.

25. Illustrate Binary Fission (p 98)Include a caption.

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.

• In eukaryotes, does having more chromosomes mean you are a more complex organism? ____

27. Illustrate the human chromosome (You must show all 23 pairs of chromosomes)

28. Eukaryotic Cell Cycle

• There are three stages in the eukaryotic cell cycle:– ____________- 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 Eukaryotic Cell CycleDraw, label, and write a caption for the three stages of a cell’s cycle. (Hint: there are six total drawings because Mitosis has 4 phases)
