POWERHOUSE OF THE CELL
What is the process called when particles move from an area of high concentration to an area of low concentration?
Diffusion
Whales eat Krill and Krill eat Phytoplankton.
Why would protecting the phytoplankton help the whales?
because phytoplankton are food for the whales food.
Which cell structure acts as a protective barrier that controls what enters and leaves the cell?
Cell Membrane
How are mitochondria and chloroplasts similar?
They both provide energy for the cell
What is the purpose of cellular respiration in animal cells?
to use food and oxygen to create energy
A glass house can keep plants alive in a self regulated internal climate. In 1960, David Latimer planted four seedlings in a jug and he hasn’t watered it since 1972. However, the plants are still alive! How can these plants live without water?
a. The plants have learned to live without any water
b. The water is being recycled in the plants
c. The plants are no longer living
d. These plants do not use photosynthesis
b. The water is being recycled in the plants
What are the three parts of the cell theory?
The cell is the smallest/most basic unit of life
All new cells come from pre-existing cells
All living things are made of one or more cells
Which statement about cellular respiration and photosynthesis is correct?
a. Both processes create oxygen
b. Both processes use carbon dioxide
c. Cellular respiration releases carbon dioxide, photosynthesis uses it
d. Photosynthesis releases carbon dioxide, cellular respiration uses it
C. Cellular respiration releases carbon dioxide, photosynthesis uses it.
When people exercise and their heartbeat rises, what is a direct result of a raised heartbeat?
Blood pumps faster around the body
Yeast is used to bake bread and rolls. When dry, yeast looks like a light brown powder. When mixed with water and sugar, yeast grows and reproduces, producing gasses that make dough rise. A student is given a beaker containing a sample of dry yeast.
Which investigation will produce data to best support the claim that yeast is a living thing?
A. Keep the dry yeast in sunlight for several days, and see if more yeast appears.
B. Combine dry yeast with water, and measure the heat released from the mixture.
C. Mix dry yeast with water and sugar, and measure the mixture’s change in volume.
D. Mix dry yeast with water and sugar, and use a microscope to observe if cells are visible.
C. Mix dry yeast with water and sugar, and measure the mixture’s change in volume.
