Matter
This is the smallest unit of a substance that maintains its properties.
Answer: What is an atom?
All cells have this, cytoplasm, organelles, and DNA.
Answer: What is a cell membrane?
100: This process breaks large molecules into smaller molecules within cells.
Answer: What is cellular respiration?
This organelle produces energy for the cell through the process of oxidative phosphorylation.
Answer: What are mitochondria?
100: This system forms a protective covering on the outside of the body, consisting of the skin, hair, nails, and associated structures.
Answer: What is the integumentary system?
Groups of atoms bonded together are called this.
Answer: What are molecules?
Cells without nuclei or membrane-bound organelles are called this.
Answer: What are prokaryotic cells?
200: These four types of macromolecules contain carbon and other elements, and are essential for the structure and function of cells.
Answer: What are proteins, carbohydrates, nucleic acids, and lipids?
This system of folded membranes is where proteins, lipids, and other materials are synthesized and transported within the cell.
Answer: What is the endoplasmic reticulum?
200: This system allows for voluntary and involuntary movement of the body, consisting of skeletal, smooth, and cardiac muscles.
Answer: What is the muscular system?
A substance's characteristics relate to the _ composing it.
Answer: What are atoms?
300: According to cell theory, all living things are made up of one or more of these.
Answer: What are cells?
a key molecule in cellular respiration, C6H12O6
Answer: What is the chemical formula for glucose?
Plant cells have this, which provides structure, protection, and support for the cell.
Answer: What is a cell wall?
This system responds to changes in the internal and external environment, consisting of the brain, spinal cord, and nerves.
Answer: What is the nervous system?
E = mc^2 is the famous equation that describes the relationship between these fundamental components of matter.
Answer: What are energy and mass?
This cellular organelle acts as the "powerhouse" of the cell, converting nutrients into usable energy through the process of cellular respiration
Answer: What are mitochondria?
This process uses the sun's energy to convert carbon dioxide and water into glucose and oxygen, providing food for the plant cell.
Answer: What is photosynthesis?
Animal cells contain these, which are responsible for the digestion and recycling of cellular waste and worn-out organelles.
Answer: What are lysosomes?
This system regulates growth, development, and homeostasis through the release of hormones, consisting of glands such as the pituitary, thyroid, and adrenal glands.
Answer: What is the endocrine system?
These are the three fundamental subatomic particles that make up all atoms.
Answer: What are protons, neutrons, and electrons?
500: This cellular process is responsible for the division of a single cell into two or more daughter cells, allowing for growth, repair, and reproduction.
Answer: What is mitosis?
This process is the reverse of photosynthesis, where glucose and oxygen are broken down to release energy, carbon dioxide, and water.
Answer: What is cellular respiration?
This process is the series of stages a eukaryotic cell goes through to divide its nucleus and cytoplasm, resulting in two daughter cells with identical genetic material.
Answer: What is mitosis?
This system returns fluids to the blood and helps get rid of pathogens, consisting of lymph vessels, lymph nodes, and lymphatic organs like the spleen and thymus.
Answer: What is the lymphatic system?
