Cell Divison
A cell makes a copy of its DNA before dividing.
What is interphase?
The green igment that helps capture sunlight energy
What is chlorophyll?
The organelle where the second stage of cellular respiration takes place.
What are mitochondria?
The process cells can use to release a small amount of energy when oxygen is unavailable or limited.
What is fermentation?
The original energy source that powers photosynthesis.
What is sunlight?
A student observes chromosomes arranged in a line across the middle of a cell.
What is Metaphase?
A plant will not go through this process if it does not have access to sunlight.
What is photosynthesis?
The sugar that cells break down to release usable energy.
What is glucose?
The type of fermentation that produces alcohol and carbon dioxide.
What is alcoholic fermentation?
Glucose + Oxygen vs. Carbon Dioxide + water
What are the products that cycle between photosynthesis and cellular respiration?
A person gets an injury that damages some of their body tissue. Cell division occurs and replaces/repairs the damged cells.
What is are the functions of cell division?
The reactants of photosynthsis
What are sunlight, water and carbon dioxide?
The two main reactants used during cellular respiration.
What are glucose and oxygen?
The type of fermentation that can occur in muscle cells when oxygen is limited.
What is lactic acid fermentation?
Plants have mitochondria but animal cells do not have chloroplasts.
What is why plants can also perform cellular respiration but animals do not perform photosynthesis?
New cells do not recieve the correct genetic information.
What is a problem with the chromosome dividing properly?
The products of photosynthesis.
What are glucose and oxygen?
The two main waste products released during cellular respiration.
What are carbon dioxide and water?
What causes muscle burn.
What is increasing acidity in your muscles?
The different energy sources in photosynthesis vs. cellular respiration.
What are sunlight vs. ATP?
This is when the cell begins to pinch in the middle, but its organelles and cytoplasm have not divided yet.
What is telophase?
Where photosynthesis occurs.
What are chloroplasts?
The folded membranes inside mitochondria provide more of this, helping the organelle perform its job.
What is surface area?
The process that releases more energy from glucose than fermentation because it uses oxygen.
What is cellular respiration?
A decrease in photosynthesis in a marsh ecosystem reduces glucose production. This can affect organisms that depend on plants for food and may also reduce oxygen production. The process that normally releases usable energy from glucose in those organisms is also affected if less food is available.
What are the connections between photosynthesis, cellular respiration, and energy flow through an ecosystem?
