G-CAT

4th Chapter Test Review (SNB page 32)

Order the terms to show the flow of energy.1. Zebra, Sunlight, Grass, Lion2. Heterotroph, Autotroph, Sunlight


3. Photosynthesis is how plants/autotrophs create their food.

4. Photosynthesis benefitsanimals/heterotrophs by creating food to be eaten.

5. What sugar and oxygen producing process occurs in a leaf?

(glucose is a simple sugar)

6. What are the two products of photosynthesis?


7. Leaf cells use the energy in sunlight to make…


8. Capturing the energy in sunlight and using it to produce food is the main function of …

9. Respiration is the process cells use to get …… from food.

10. The three products of respiration are ……

11. Mitochondria convert the energy in sugars into a form of energy the cell can use.(Converts food energy into cell energy)

12. Photosynthesis makes sugar and respiration breaks sugar down, so the processes are opposite.


13. The main purpose of cell division is to increase the number of cells in an organism.

14.DNA replication occurs beforea cell divides because each daughter cell will need a completecopy of the DNA.

15. A cell’s genetic material is copied during DNA replication.

Original Unzipping Two Replicated Copies

Note: A pairs with T and C pairs with G every time.

15. A cell’s genetic material is copied during DNA replication.


16. G-CAT helps one remember the four nitrogen bases of DNA:Guanine, Cytosine, Adenine, and Thymine


17. A pair of base makes up each step/rung of the DNA ladder; A T and C G. (AT is a word)⇿ ⇿


18. In mitosis, the parent cell’s nucleus divides into two new nuclei. In cell division, the parent cell divides into two daughter cells.

19. Chromosomes separate at their centromeres during anaphase of mitosis.

20. The process by which a plant cell becomes a leaf, stem, or root cell is called…

Differentiation of cells allows cells to become root, leaf and stem cells.

DNA Bases and Replication (how DNA copies are made)

Original Unzipping Two copies

A and T make a step or rung.C and G make a step or rung.

Bell Work 3/19 (Use complete sentences /SNB page 31)

What is the function of a chloroplast?1. The main purpose of the chloroplast is….What is the purpose of a mitochondrion?2. The function of a mitochondrion is…3.If a parent cell is going to divide to make two daughter cells, how does it prepare and when?4.What four materials are involved in photosynthesis and cellular respiration?
