Chapter 3 Vocabulary - Science

What is Photosynthesis?

• The process by which plants and other autotrophs capture and use light energy to make food from carbon dioxide and water.

• The process by which animals convert food into energy.

• The method by which plants absorb nutrients from the soil.

• The way in which plants release oxygen into the atmosphere.

What is a Heterotroph?

• An organism that cannot make its own food and gets food by consuming other living things.

• An organism that produces its own food through photosynthesis.

• An organism that lives only in water.

• An organism that can survive without consuming any food.

What is an Autotroph?

• An organism that is able to capture energy from sunlight or chemicals and use it to produce its own food.

• An organism that relies on consuming other organisms for energy.

• A type of plant that only grows in the dark.

• An animal that can survive without water.

What is Chlorophyll?

• A green photosynthetic pigment found in the chloroplasts of plants, algae, and some bacteria.

• A type of carbohydrate found in the cell walls of plants.

• A protein that acts as an enzyme in cellular respiration.

• A mineral that is essential for bone health.

What is Cellular respiration?

• The process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.

• The process of converting sunlight into chemical energy in plants.

• The process of cell division resulting in two daughter cells.

• The process of synthesizing proteins from amino acids.

What is Fermentation?

• The process by which cells release energy by breaking down food molecules without using oxygen.

• The process of converting sunlight into chemical energy in plants.

• The breakdown of food in the stomach using digestive enzymes.

• The process of water evaporation from plant leaves.

What is a Product in scientific terms?

• A substance that is manufactured and is the result of an action or process.

• A raw material used in the production of goods.

• A byproduct of a chemical reaction that is not useful.

• A theoretical concept with no physical form.

What is a Reactant?

• A substance that takes part in and undergoes change during a reaction.

• A product formed in a chemical reaction.

• A catalyst that speeds up a chemical reaction.

• A byproduct of a chemical process.

What is ATP?

• The source of energy for use and storage at the cellular level.

• A type of protein found in the cell membrane.

• A form of DNA that carries genetic information.

• A type of enzyme that breaks down carbohydrates.

What are Mitochondria?

• Organelles within eukaryotic cells that produce adenosine triphosphate (ATP).

• Structures that store genetic information in the form of DNA.

• Organelles responsible for photosynthesis in plant cells.

• Components of the cell responsible for protein synthesis.
