Process 1 is called
Interphase
Mitosis
Prophase
Cytokinesis
What word should you use to compare cell C to cell D
Different
Similar
Identical
How many "sticks" (individual chromosomes) would you find in cell B if it were a human cell?
92
46
23
What 2 steps are being shown in process 2?
Interphase + Mitosis
Mitosis + Cytokinesis
Interphase + Cytokinesis
The halves of an x-shaped chromosome are held together at a part called the
nucleus
chlorophyll
centromere
golgi apparatus
Uncontrolled cell division is a characteristic of
photosynthesis
mitosis
cancer
regeneration
Plant cells can make energy-rich molecules and then later break them down to use that energy. These activities require the use of
chloroplasts and vacuoles
cell walls and ribosomes
chloroplasts and mitochondria
ribosomes and mitochondria
Here is a biological formula:
carbon dioxide + water +sun→glucose +oxygen
What is the name of this process?
cellular respiration
mitosis
photosynthesis
interphase
In human cells, oxygen molecules are used directly in a process that
makes energy
makes new identical cells
makes carbohydrate molecules (glucose)
alters DNA
The energy used to obtain, transfer, and transport materials inside an organism comes directly from
ATP
DNA
Sunlight
Glucose
This diagram shows cellular respiration.
What do the arrows leaving the mitochondria represent?
Glucose
Oxygen
Carbon Dioxide
DNA
Which substance is represented by the X in the equation for respiration?
glucose + X → water + carbon dioxide
chlorophyll
ATP
oxygen
carbon dioxide
during cellular respiration, organisms generally use
carbon dioxide and give off oxygen
nitrogen and give off carbon dioxide
oxygen and give off nitrogen
oxygen and give off carbon dioxide
Photosynthesis changes water and carbon dioxide into
Sugar and oxygen
Sugar and nitrogen
Protein and oxygen
Protein and nitrogen
Process X is called
Photosynthesis
Cellular Respiration
Mitosis
Cell Division
Process Y is called
Photosynthesis
Cellular Respiration
Mitosis
Cell Division
Which statement is true about the organisms that go through these processes?
Process X happens in animals but not plants
Process Y happens in animals but not plants
Both X and Y happen in ALL living things
Both X and Y happen in plants
When an organism reproduces asexually, it usually has
1 parent and half the chromosomes of the parent
1 parent and the same chromosome number as the parent
2 parents and double the chromosome number as either parent
2 parents and the same chromosome number as the parent
What is the tiny openings that let in the carbon dioxide needed for photosynthesis?
stomata
xylem
phloem
chloroplast
Which organism go through cellular respiration?
animals
plants
both animals and plants
none
Which of the following is a reactant of cellular respiration?
Glucose
Carbon Dioxide
Water
ATP
Which of the following is a product of cellular respiration?
Glucose
Carbon Dioxide
Oxygen
Radiant Energy
Which statement is true regarding cellular respiration?
The reactants of cellular respiration are identical to the reactants of photosynthesis.
The reactants of cellular respiration are taken from the products of photosynthesis.
The products of cellular respiration are the same as the products of photosynthesis
Cellular respiration only occurs in autotrophs, photosynthesis occurs only in heterotrophs.
What is the ultimate goal of photosynthesis?
To make oxygen for humans
To make glucose
To make energy/ATP
To breathe
a→b Reactant or Product?
A is the product, B is the reactant
A is the reactant, B is the product
A and B are reactants
A and B are products
What happens during interphase?
The cell divides into 2 identical cells
The DNA is replicated
The nucleus divides into 2 identical nuclei
What happens during mitosis?
