Biology final

QuestionAnswer
Pigments reflect the same wave length of light they absorb False
ADP has more energy than ATP False
We get Energy from breaking chemical bonds True
Folded thylakoid that resemble stacks of pancakes I called stroma False
And important waste product of photosynthesis is oxygen True
What is the product of Calvin cycle Sugar molecule/glucose
What product of the light reactions of photosynthesis is released and does not participate further in photosynthesis O2
An object that absorbs all colors appear Black
Goal of photosynthesis is to produce Glucose
Where in the chloroplast is the reaction of the Calvin cycle occur Stroma
Where in the chloroplast does the light reaction occur Thylakoid membrane
Photosynthesis occurs in two stages called Dark reactions and light reactions
Stroma is a solution that surrounds the Granum
Which of the following is an autotroph mushroom, dog, monkey, tree Tree
To the following is NOT an example of a heterotroph Mushroom,leopard, grass, human Grass
Energy is released from ATP when Phosphate group is removed
Most plants appear green because chlorophyll Doesn't absorb green light
A granum is a Stack of thylakoids
If carbon dioxide is removed from a plant's environment, what would you expect to happen to its production of high-energy sugars No sugars will be produced
All organisms require energy to Carry out Life processes True
When light hits a plant all of the wavelengths are absorbed and used to make sugar False
Most plants are heterotrophic False
Photosynthesis is a process that takes place in autotrophs True
The major light absorbing pigment in plants is chlorophyll True
Carbon dioxide and water, in the presence of sunlight, will react to form sugars and oxygen gas True
Plant cells use light to make ATP and NADPH True
Energy is required for a variety of life processes including Growth and reproduction, movement, and transport of certain materials across the cell membrane
Heterotrophs are organisms that can Consume other organisms for energy
Suspended in the fluid stroma of chloroplasts are Stacks of thylakoids call Grana
The sun is considered the ultimate source of energy for life on earth because Either photosynthetic organisms or organisms that have eating them provide energy for all other organisms on earth
The source of oxygen produced during photosynthesis is Water
As a result of photosynthesis Our atmosphere is now rich in oxygen gas
Products of light reactions of photosynthesis that are required by dark reactions are ATP and NADPH
The dark reactions of photosynthesis are Require ATP and NADPH, can occur in both light and dark conditions, generate glucose
What are the products of light reaction ATP, NADPH, O2
When you break light apart with a prism you can see the components of white light. What colors are included Red, indigo, orange, yellow, green, blue, Violet
What are the products of the dark reactions ADP , NADP , C6H12O6
The rate at which materials enter and leave through the cell membrane depends on the cells Surface area
The cell cycle is the Series of events that a cell go through as they grow and divide
As a cell becomes bigger it Volume increases faster than its surface area
As a cell grows it Places more demands on its DNA
Which stages occur during interphase G1, G2 , S phase
What is not a way that sell division solve the problem of cell growth Cell division increases the mass of the original cell
During the cell cycle when are the chromosomes visible Only during mitosis
What is the S phase DNA replication
Which events occur during interphase Cell growth
Which represents the stages of mitosis in their proper sequence Prophase, metaphase, anaphase, telophase
Look at figure 10–2, cell division is represented by which letter D
Look at figure 10–2, interphase is represented by what letter ABC
During which stage of mitosis do the chromosomes line up along the middle of the dividing cell Metaphase
What is the role of the spindle during mitosis Help separate the sister chromatids of a chromosome
Chromosomes consists of DNA that is Taylor coiled around proteins called Histones
The two main stages of the actual division of a cell include Mitosis and cytokinesis
What is the middle of a chromosome called Centromere
Draw a chromatid 1/2 of a chromosome
What is the role of centrioles in cell division Organize the spindle fibers
If a cell has 20 chromosomes how many chromosomes Will its daughter have after mitosis 20
During mitosis chromosomes condense and become visible during Prophase
In mitosis the sister chromatids separate into individual chromosomes and move apart during Anaphase
During ------- of mitosis, the chromosomes father st opposite ends of the cell and nuclear membranes begin to form Telophase
In mitosis, the nuclear membrane breaks down during Prophase
The term cytokinesis refers to the division of a cells Cytoplasm
Cytokinesis in a plant cell creates a what Cell plate
Draw a centriole At the top of a spindle fiber
Cancer is a disorder in which some cells have lost the ability to control their Growth rate
Compared with small cells, larger cells have more trouble Moving materials in and waste products out
When chromosomes are not visible, the DNA material is referred to as Chromatin
What is the term for the programmer death of cells Apoptosis
2 internal factors that are important in advancing the cell cycle are Kinases and cyclins
Which phrase best describes cancer Uncontrolled cell growth
Substances know to produce or promote cancer are Carcinogens
Explain the differences between the division of an animals cell compared to a plant In cytokinesis animal cells form a furrow, which slowly pinches the cells shut forming 2 new cells. In plant cells the membrane can't punch inward because of the cells wall, so instead a cell plate forms which seperate the 2 new cells
What role does cell division play in living things, say 2 Helping organisms grow in size, if cells didn't divide then organisms would stay the same size. Another reason we need cell division is to heal cuts or wounds if a cell division didn't happen then the cut would never heal and close up
