Cells and Organelles
This principle states that all living organisms are composed of one or more cells.
What is cell theory?
This organelle controls the activities of the cell and contains DNA.
What is the nucleus?
This system transports oxygen, nutrients, and wastes throughout the body.
What is the circulatory system?
Clue: This gas is removed from the atmosphere during photosynthesis.
What is carbon dioxide (CO₂)?
This process uses light energy to convert carbon dioxide and water into glucose and oxygen.
What is photosynthesis?
This level of organization is the simplest level that still retains the properties of life.
What is a cell?
This structure regulates what enters and leaves the cell to maintain internal balance
What is the cell membrane?
These two systems work together to deliver oxygen to cells and remove carbon dioxide.
What are the respiratory and circulatory systems?
This process returns carbon dioxide to the atmosphere from organisms.
What is cellular respiration?
This organelle is the site of cellular respiration.
What is the mitochondria?
Arrange these from simplest to most complex: organ, molecule, tissue, cell.
What is molecule → cell → tissue → organ?
This process requires energy and moves substances against a concentration gradient.
What is active transport?
This system defends the body against pathogens such as bacteria and viruses.
What is the immune system?
These are places where carbon is stored, such as oceans and fossil fuels.
What are carbon reservoirs?
These are the reactants required for photosynthesis.
What are carbon dioxide, water, and light energy?
This level consists of similar cells working together to perform a common function.
What is a tissue?
(⭐ Daily Double) [Wager up to your total points]
Clue: This organelle is found only in plant cells and is responsible for photosynthesis.
What is the chloroplast?
This system breaks down food into nutrients that can be absorbed into the bloodstream.
What is the digestive system?
This group of organisms obtains energy directly from sunlight.
What are producers?
This process releases energy by breaking down glucose using oxygen.
What is cellular respiration?
Nonliving components of matter are limited to these two levels of organization.
What are atoms and molecules?
This term describes the maintenance of stable internal conditions despite external changes.
What is homeostasis?
This process describes how body systems work together to maintain stable internal conditions.
What is homeostasis?
This law states that matter cannot be created or destroyed in the carbon cycle.
What is the law of conservation of mass?
Explain how photosynthesis and respiration demonstrate conservation of matter.
What are the products of one process that are the reactants of the other, so matter is recycled?
