Vocabulary Matching (1 - 10)

1. Organisms that make their own food: Autotrophs (J) - Autotrophs are defined as organisms capable of producing their own food.
2. Site of photosynthesis: Chloroplasts (A) - Photosynthesis occurs within chloroplasts in plant cells.
3. Process occurs in cytoplasm: Glycolysis (G) - Glycolysis, the first step of cellular respiration, takes place in the cytoplasm.
4. \( C_6H_{12}O_6 \): Glucose (D) - The chemical formula \( C_6H_{12}O_6 \) represents glucose.
5. Process does not require oxygen: Anaerobic (B) - Anaerobic processes are those that occur without the presence of oxygen.
6. Process requires oxygen: Aerobic (C) - Aerobic processes need oxygen to proceed.
7. Adenosine triphosphate: ATP (E) - ATP is the abbreviation for adenosine triphosphate.
8. Energy storing molecule: ATP (E) - ATP stores energy that cells can use for various functions.
9. The anaerobic process of splitting glucose and forming two molecules of pyruvic acid: Glycolysis (G) - Glycolysis breaks down glucose anaerobically into pyruvic acid.
10. The ability to do work: Energy (H) - Energy is the capacity to do work.

Question 11: Filling the Table

	Cellular Respiration	Photosynthesis
Products	Carbon Dioxide (\( CO_2 \)), Water (\( H_2O \)), and ATP	Glucose (\( C_6H_{12}O_6 \)) and Oxygen (\( O_2 \))
What organelle?	Mitochondria	Chloroplasts

Question 12: Relationship between Photosynthesis and Cellular Respiration

Photosynthesis and cellular respiration are complementary processes. Photosynthesis (in chloroplasts) uses carbon dioxide and water, along with sunlight energy, to produce glucose and oxygen. Cellular respiration (in mitochondria) uses glucose and oxygen to produce carbon dioxide, water, and ATP (energy). The oxygen produced by photosynthesis is used in cellular respiration, and the carbon dioxide produced by cellular respiration is used in photosynthesis. They form a cycle that helps maintain the balance of gases in the ecosystem and provides energy and organic compounds for life.

Question 13: Organisms that Perform Photosynthesis

Organisms that perform photosynthesis are mainly autotrophs, specifically plants, algae, and some bacteria (like cyanobacteria). These organisms have the necessary pigments (like chlorophyll) and organelles (chloroplasts in plants and algae) to capture light energy and convert it into chemical energy stored in glucose.

Question 14: Organisms that Perform Cellular Respiration

All living organisms perform cellular respiration. This includes plants, animals, fungi, bacteria, and protists. Every cell needs energy to carry out its functions, and cellular respiration is the process that breaks down organic compounds (like glucose) to release energy in the form of ATP, which is used for cellular work.
