Science Super Quiz

explain what an element is, and use the periodic table and an element's atomic number to determine how many protons it has.

An element is any substance that cannot be broken down into simpler substances. The atomic number is located above the element symbol, in the upper left-hand corner of the square. The atomic number will tell you how many protons make up a single atom of an element.

list the reactants (inputs) and products (outputs) of photosynthesis

During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

describe the relationship between photosynthesis and cellular respiration

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Concentration

The certain amount of a substance that is in something

Photosynthesis - organelle =

the chloroplast

list the ways in which water plays a key role in living things.

1. Most chemical reactions depend on substances that have to be dissolved in water to react 2. Water helps cells keep their shape 3. Helps keep the temperature of cells from changing rapidly 4. Carrying substances into and out of cells 5. (also animals and most living things need to consume water)

Solution

A solution of solute and solvent (ex. Sugar water)

explain what a molecule and compound are.

Compounds form when two or more elements combine chemically. (ex. Carbon dioxide and water) Molecules are a group of atoms bonded together.

describe the structure and function of DNA.

DNA function- genetic material that carries information Structure: double helix

list the reactants (inputs) and products (outputs) of cellular respiration

During cellular respiration, the reactants—glucose (sugar) and oxygen—combine together to form new products: carbon dioxide molecules and water molecules. ATP is produced as the form of energy that can be used for other cellular processes.

4 major classes of biomolecules

The four major classes of biomolecules are carbohydrates, lipids, proteins, and nucleic acid.

solute

The substance, usually a solid being dissolved. (ex.sugar)

Solvent

The substance, usually the liquid (water, ethanol, etc.) that dissolves the solute. (ex. water)

which cell types undergo cellular respiration

living things, both autotrophs and heterotrophs can perform cellular respiration

cellular respiration- organelle=

mitochondria

which cell types undergo photosythesis

plant cells and algal (protist) cells—can perform photosynthesis

subatomic particles

protons, neutrons and electrons
