Cell Transport
What is the difference between passive and active transport?
Active transport requires the cell's energy while passive transport does not.
What is needed for a plant to perform photosynthesis?
Energy from the sun, water, and carbon dioxide
Where does the first stage of cellular respiration take place?
The cytoplasm
Use the acronym IPMATC to write down the six stages of the cell cycle.
Interphase, prophase, metaphase, anaphase, telophase, cytokinesis
What product of fermentation causes a burning sensation in your muscles?
Lactic acid
What are the two forms of passive transport?
Diffusion and osmosis
What is produced during photosynthesis?
Glucose and oxygen
Where does the second stage of cellular respiration take place?
The mitochondria
In which stage of the cell cycle are chromosomes pulled by spindle fibers to opposite ends of the cell?
Anaphase
What are the two purposes of cell division during mitosis?
Growth and repair of cells
What is the difference between exocytosis and endocytosis?
Endocytosis brings large particles into the cell while exocytosis allows large particles to leave the cell.
What is an autotroph?
An organism that makes its own food
What is a heterotroph?
An organism that gets its energy from eating other organisms
In which stage of the cell cycle does the cell split into two daughter cells?
Cytokinesis
What is fermentation and when do cells do it?
Fermentation is an energy releasing process that does not require oxygen. Fermentation occurs during intense exercise when cells are using oxygen faster than it can be replaced.
What is the difference between facilitated diffusion and regular diffusion?
What part of the plant's cells is responsible for capturing energy from the sun?
The chloroplasts
What is the cellular respiration equation?
Glucose + oxygen = carbon dioxide + water + energy
In which stage of the cell cycle does the cell replicate its DNA and duplicate centrioles?
Interphase
In animal cells, the cell membrane squeezes together around the middle of the cell to divide the cell. In plant cells, a cell plate forms across the middle of the cell to divide the cell.
Why is cellular energy needed during active transport?
Molecules are moving from places of high concentration to places of low concentration.
Where does the hydrogen necessary to make glucose molecules come from?
Water - The plant breaking down water into hydrogen and oxygen.
Why is more energy generated during the second stage of cellular respiration than the first stage?
Because molecules are being broken down in the presence of oxygen
What happens during metaphase?
Chromosomes attach to spindle fibers at their centromeres.
In which stage of the cell cycle does the nucleus break down and in which stage does it reform?
It breaks down during prophase and is reformed during telophase.
