1

Where does the energy that a plant needs come from?

Sun

2

What is produced during photosynthesis?

Glucose sugar

3

When BTB turned yellow what did it mean?

Co2 was detected

4

What does it mean when BTB stayed blue?

No Co2 was detected

5

What matter do plants take in to make their food?

Co2 and H2o

6

Do plants do both photosynthesis and cellular respiration? Why?

Both; the take in/give off energy

7

Do prokaryotic cells have a nucleus?

No

8

What is the amount of prokaryotic cells?

1 cell

9

Do prokaryotic cells have complex organelles or ribosomes?

Ribosomes

10

Do eukaryotic cells have a nucleus?

Yes

11

What is the amount of cells in a eukaryotic cell?

1+

12

Do eukaryotic cells have complex organelles or ribosomes?

Complex organelles

13

Which cell organelle stores genetic information?

Nucleus

14

Which cell organelle produces ATP from glucose?

Mitochondria

15

What are 3 organelles found in a plant cell that is not found in an animal cell?

Cell wall, central vacuole, chloroplasts

16

What does an enzyme do to the amount of energy needed to start a reaction?

Lowers energy

17

I'm an enzyme reaction, what has to be a perfect match with the enzyme in order for the reaction to work?

Substrate

18

What can increase the rate of an enzyme reaction?

Temperature

19

What 3 substances get cycled around in an ecosphere between algae, shrimp, and bacteria?

Carbon oxygen nitrogen

20

What substance is used by the shrimp and by the bacteria?

Oxygen

21

What is a closed system?

Matter does not enter or leave

22

What is the original source of energy for nearly all of life on earth?

Sun

23

Which type of organisms provide all of the energy to support an ecosystem?

Producers

24

What molecule in plants stores energy from the sun and is the main product of photosynthesis?

Cellulose

25

What percentage of the energy gets passed from one trophic level to the next in a food chain?

10%

26

Where does the energy that is not passed on from one level in a food web, go?

Used by organism to live

27

3 molecules that makeup DNA nucleotide

Deoxyribose sugar, nitrogen base, phosphate

28

3 molecules that make up RNA nucleotide

Ribose sugar, nitrogen base, phosphate

29

What are the strong/weak bonds in the DNA nitrogen base?

AT & CG

30

What is the information stored in DNA used for?

Make copies (mRNA)

31

How many nucleotides make up the codon for one amino acid?

3

32

A segment of DNA that codes for a specific trait/protein

Gene

33

What determines an individual's traits?

The genes you inherit from your parents

34

Where in a cell are proteins assembled?

Ribosome

35

How does the information in DNA get from the nucleus to the ribosome?

Bonds between bases break, RNA copies DNA code, RNA goes to ribosome

36

What cell process creates daughter cells that are genetically different from the original parent cells?

Meiosis

37

What is the goal of creating genetically different sex cells? (Gametes)

Diversity and a greater survival chance

38

Contains 2 complete sets of chromosomes (1 from each parent)

Diploid cell

39

Single set of unpaired chromosomes (half of diploid cell)

Haploid cell

40

How do sperm and egg cells differ from all other cells genetically?

Half as many chromosomes
