In this process, plants use the energy of sunlight to convert water and carbon dioxide into high-energy carbohydrates (sugars and starches), and oxygen as a waste product.
Calvin cycle
Photosynthesis
Light-dependent reactions
Cellular respiration
This is the overall equation of photosynthesis:
Carbon dioxide + water => sugars + oxygen
Sugars + oxygen => carbon dioxide + water
Photosynthesis uses energy of sunlight to convert water and carbon dioxide into oxygen and high-energy what?
Electrons
Oxygen
Hydrogens
Sugars
These are light-absorbing molecules used by plants to gather the sun’s energy.
Pigments
Thylakoids
Chloroplasts
Grana
This is the principal pigment of plants.
Thylakoids
Grana
Chlorophyll
Chloroplast
These are the regions of visible spectrum in which chlorophyll absorbs light very well.
Yellow
Green
Blue, violet, and red
Yellow, and orange
It is the process that releases energy by breaking down glucose and other food molecules.
Glycolysis
Cellular respiration
Krebs cycle
Electron transport chain
Which one of these is the correct equation for cellular respiration?
6O2 + C6H12O6 => 6CO2 + 6H2O
6CO2 + 6H2O => C6H12O6 + 6O2
This pathway follows glycolysis in the absence of oxygen. It releases energy from food molecules by producing ATP.
Krebs cycle
Fermentation
Electron transport chain
Photosynthesis
Since fermentation does not require oxygen, it is said to be
Aerobic
Anaerobic
This molecule is used during photosynthesis, and produced during cellular respiration
Carbon dioxide
Oxygen
Water
ATP
This molecule is produced during photosynthesis, and used during cellular respiration
Carbon dioxide
Oxygen
Water

Heterotrophs
It is one of the principal compounds used by cells to store and release energy
ATP
ADP
Glucose
Water
ATP is a compound that consist of
adenine, ribose, and two phosphate groups.
adenosine, ribose, and three phosphate groups .
adenine, ribose, and three phosphate groups.
adenosine, glucose, and three phosphate groups.
How many phosphate groups does ATP have?
3
2
4
6
By adding a phosphate group to ADP molecules, cells
release small amounts of energy
release large amounts of energy
store small amounts of energy
store large amounts of energy
Energy stored in ATP is released by
removing ribose
breaking the chemical bond between the second and third phosphates
adding an adenine
breaking the chemical bond between the first and the second phosphates
ATP stores large amounts of energy over long periods of time
True
False
This molecule is the best for energy storage.
ATP
ADP
Glucose
Starch
Which of the following is NOT related to a cell’s ratio of surface area to volume?
cell size
rate of growth
number of nuclei
efficiency of cell’s transport of oxygen and nutrients
To obtain a cell’s ratio of surface area to volume on must
divide the surface area by the volume
divide the volume by the surface area
multiply the surface area times the volume
subtract the volume from the surface area
If a cell’s surface area is 9 cm3 and its volume is 1 cm3, then what is its ratio of surface area to volume
1:9
9:1
9
8
As a cell grows in size
its surface area increases more rapidly than its volume
its volume decreases more rapidly than its surface area
its volume increases more rapidly than its surface area
The process by which a cell divides into two new daughter cells is called
Cell growth
Cytokinesis
Cell division
Cell fractionation
The process of cell division results in
sister chromatids
mitosis
two daughter cells
unregulated growth
Sister chromatids are attached to each other at an area called
Centriole
Centromere
Spindle
Chromosome
The division of the cell nucleus during M phase of the cell cycle is called
Meiosis
Mitosis
Cytokinesis
Metaphase
It is the phase divided into G1, S, and G2
Telophase
Mitosis
Interphase
Anaphase
These are two tiny structures located in the cytoplasm near the nuclear envelope at the beginning of prophase
Centrioles
Centromeres
Spindles
Chromosomes
A fan-like microtubule structure that helps separate the chromosomes
Centriole
Centromere
Spindle
Chromosome
During this phase in mitosis, the chromosomes line up across the center of the cell
prophase
metaphase
anaphase
telophase
During this phase in mitosis, the chromosomes become visible. The centrioles take up positions on opposite sides of the nucleus
prophase
metaphase
anaphase
telophase
During this phase in mitosis, the chromosomes move until they form two groups near the poles of the spindle
prophase
metaphase
anaphase
telophase
During this phase in mitosis, a nuclear envelope re-forms around each cluster of chromosomes. The nucleolus becomes visible in each daughter nucleus
prophase
metaphase
anaphase
telophase
It is the division of the cytoplasm in a cell
Mitosis
Meiosis
Cytokinesis
Apoptosis
Each of the chromosomes from the male parent has a corresponding chromosome from the female parent, this means that those two sets of chromosomes are
Heterologous
Homologous
Diploid
Haploid
This type of cell contains two sets of homologous chromosomes and is represented as 2N
Heterologous
Homologous
Diploid
Haploid
This type of cell has a single set of chromosomes and is represented as N
Heterologous
Homologous
Diploid
Haploid
Because the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell, we say that meiosis is a process of
Addition division
Reduction multiplication
Reduction division
