Photosynthesis
The source of energy for photosynthesis?
Sunlight
What are the reactants for cellular respiration?
Sugar and oxygen
What does mitosis produce?
2 identical daughter cells.
Why do plant cells simultaneously produce and absorb CO2?
They are doing both photosynthesis and cellular respiration at the same time.
What is interphase?
The rest of the cell cycle besides mitosis. Where the cell carries out its normal functions and prepares for division.
Why are photosynthetic organisms typically green?
Reflect green light because it is not used for photosynthesis.
Where does cellular respiration occur?
Mitochondria
What are the phases of mitosis?
Prophase, metaphase, anaphase, telophase.
The process in which the cell divides into two identical daughter cells after mitotic division of the nucleus.
cytokinesis
Explain why a low surface area to volume ratio is problematic for cells
They become inefficient at carrying out internal transport, and diffusion in and out takes longer.
Photosynthesis equation?
CO2+H2O-->Sugar+O2
Cellular Respiration Equation
Sugar +O2--> CO2+H2O
How does the genetic information in a daughter cell compare to the genetic information in the parent cell?
Identical
Adult stem cells are multipotent meaning that...
They can be come many different types of cells.
The type of organism that produces its own energy and does not eat other things for food.
autotroph.
What organelle is necessary for photosynthesis to occur?
Chloroplast
Explain how photosynthesis and cellular respiration are related to each other?
Inputs of one are outputs of the other.
What are 3 possible reasons a cell might carry out mitosis?
Grow, heal, getting too large
A cell with 36 chromosomes goes through cellular division. How many daughter cells are produced and how many chromosomes are in each daughter cell?
2 daughter cells and 36 chromosomes in each.
In the absence of oxygen, organisms rely on these two processes to continue producing ATP for energy.
Lactic acid fermentation and alcoholic fermentation
What are the steps of photosynthesis?
Light dependent reactions, Light independent reactions (Calvin cycle)
What are the steps of cellular respiration?
Glycolysis, krebs cycle, electron transport chain
How is mitosis controlled?
Cyclins, regulatory proteins
In a zygote, an mutation is present in the DNA of a chromosome. Will that mutation still be present in the arm of that organism as an adult? Justify your response.
Yes, mutation is passed on to all body cells because those cells result from mitosis.
In Africa, there is a large area where the lion population has gone extinct and there are only large herbivores present in the area. Scientists want to reintroduce the lions but worry what impact they could have on the ecosystem. Make a claim about the impact the lions could have on both the large herbivores and on the plant growth in the region. Justify your response
