Cell Vocabulary
A living thing, like a plant, that creates its own food using sunlight.
...A producer?
The specific type of passive transport that only involves the movement of water molecules across a membrane.
...Osmosis?
This organelle, often called the "powerhouse" of the cell, is the site of cellular respiration.
...Mitochondria?
Mitosis creates ____ _____ daughter cells, while meiosis creates ______ _______ daughter cells.
...2 identical, 4 different.
The single factor that "I" deliberately changed or manipulated in an experiment.
The substances you start with in a chemical reaction, such as carbon dioxide and water in photosynthesis.
..A reactant?
When perfume is sprayed in one corner of a room and its scent soon fills the entire space, this process has occurred.
...Diffusion?
The two reactants (ingredients) needed for photosynthesis.
...Carbon dioxide and water?
The main purpose of mitosis in multicellular organisms is to replace damaged cells and this.
...Growth?
The factor that is measured or observed to see if the independent variable had an effect.
The result of a chemical reaction, such as glucose and oxygen in photosynthesis.
...A product?
The concentration gradient says that molecules naturally move from an area of ________ concentration to an area of _________ concentration, following this natural path.
...High to low?
The main sugar molecule that is created by plants and consumed by animals for energy.
...Glucose?
The entire process of the nucleus dividing (Mitosis) is followed by this final step, where the cytoplasm and organelles divide to form two separate cells.
...Cytokinesis?
These are the parts of an experiment that must be kept exactly the same across all setups to ensure a fair test.
...Constants?
This term describes the cell membrane because it allows some things to pass through while blocking others.
...Semi-permeable (or selectively permeable)?
Placing a wilted celery stalk in a glass of pure water makes it crisp again as water moves into the cells by this process.
...Osmosis?
This organelle contains chlorophyll and is the primary site of photosynthesis.
...Chloroplast?
The step during mitosis where the duplicated chromosomes line up single file (meet) in the middle of the cell.
...Metaphase?
In the gummy bear osmosis experiment, the size and color of the gummy bear is considered the ________ variable because we were able to measure the change.
...Dependent variable?
An organism, like a mushroom or bacterium, that breaks down dead organic matter and returns nutrients to the soil.
...A decomposer?
Unlike active transport, both osmosis and diffusion are classified as this type of transport because they do not require the cell to use energy (ATP).
...Passive transport?
The usable energy molecule created as a product of cellular respiration.
...ATP?
This is the specific phase where the spindle fibers pull the sister chromatids apart and move them to opposite sides of the cell., starting to separate.
...Anaphase?
A scientist is testing if solutes in water affects the rate of osmosis in gummy bears. If she changes the solutes in water (sugar and salt), what must be kept constant for accurate data? (at least two examples)?
Amount of water, temperature, type of gummy bear, time
