MS-LS1-6: Photosynthesis and Energy Flow

Front

Energy Noun

---

[en-er-jee]

Back

Energy

---

The ability to do work or cause change, which is required by all organisms to carry out life functions.

---

Example: Food is converted into energy (ATP) in the mitochondria, showing energy's role in life functions.

Front

Organism Noun

---

[or-guh-niz-uhm]

Back

Organism

---

An individual living being, such as a plant, animal, or single-celled life form, that carries out life processes.

---

Example: A single-celled organism showing its basic structure, illustrating what an organism is.

Front

Ecosystem Noun

---

[ee-koh-sis-tuhm]

Back

Ecosystem

---

A biological community of interacting organisms and their physical environment, including both living and nonliving components.

---

Example: This image shows an aquatic ecosystem with plants, fish, and water, illustrating how organisms interact with their environment.

Front

Molecule Noun

---

[mol-i-kyool]

Back

Molecule

---

A group of two or more atoms bonded together, representing the smallest unit of a chemical compound.

---

Example: The image shows a water molecule with two hydrogen atoms and one oxygen atom bonded together.

Front

Producer Noun

---

[pruh-doo-ser]

Back

Producer

---

An organism that creates its own food, typically using light energy from the sun through the process of photosynthesis.

---

Example: A plant uses sunlight to turn carbon dioxide and water into oxygen and sugar.

Front

Photosynthesis Noun

---

[foh-toh-sin-thuh-sis]

Back

Photosynthesis

---

The process used by plants and other organisms to convert light energy into chemical energy stored in food molecules.

---

Example: Sunlight, carbon dioxide, and water enter the leaf, producing glucose and oxygen in photosynthesis.

Front

Autotroph Noun

---

[aw-toh-trohf]

Back

Autotroph

---

An organism that can produce its own food from simple inorganic substances, such as a plant; also called a producer.

---

Example: A plant uses sunlight, water, and carbon dioxide to make its own food.

Front

Carbon Dioxide Noun

---

[kar-buhn dai-ok-said]

Back

Carbon Dioxide

---

A gas molecule (CO₂) taken from the air by plants and used as a raw material during photosynthesis.

---

Example: The image shows the carbon dioxide molecule (CO₂) structure, helping students understand its role in photosynthesis.

Front

Carbohydrate Noun

---

[kar-boh-hai-dreyt]

Back

Carbohydrate

---

An energy-rich organic molecule, such as a sugar or starch, that organisms use to store and release energy.

---

Example: Foods like bread and pasta are rich in carbohydrates, providing energy.

Front

Chlorophyll Noun

---

[klor-uh-fil]

Back

Chlorophyll

---

The green pigment found in the chloroplasts of plants that absorbs light energy used to carry out photosynthesis.

---

Example: The image shows a chloroplast inside a leaf, highlighting parts like the stroma and thylakoid where chlorophyll is found.
