4. what is the formula for photosynthesis and what are the reactants and the products?
5. what is the formula for cellular respiration and what are the reactants and products?
6. which process (photosynthesis or cellular respiration) stores energy in the form of glucose?
7. which process (photosynthesis or cellular respiration) uses/produces energy - atp?
8. explain gas exchange in photosynthesis.

Explanation:

• Question 12: Photosynthesis occurs in autotrophic organisms, mainly plants, some algae, and certain bacteria. These organisms have chlorophyll (in plants and algae) or other pigments (in bacteria) that can capture light energy.
• Question 13: Cellular respiration occurs in all living organisms (both autotrophs and heterotrophs). It is the process by which cells break down organic molecules (like glucose) to release energy.
• Question 14: Photosynthesis occurs in chloroplasts (in plants and algae). Cellular respiration mainly occurs in mitochondria (in most eukaryotes). In prokaryotes, cellular - respiration - like processes occur in the cell membrane or cytoplasm.
• Question 15: The formula for photosynthesis is \(6CO_2 + 6H_2O+light\ energy

ightarrow C_6H_{12}O_6 + 6O_2\). Reactants are carbon dioxide (\(CO_2\)) and water (\(H_2O\)), and products are glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)).

• Question 16: The formula for cellular respiration (aerobic) is \(C_6H_{12}O_6+6O_2

ightarrow 6CO_2 + 6H_2O+energy\). Reactants are glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)), and products are carbon dioxide (\(CO_2\)), water (\(H_2O\)), and energy (in the form of ATP).

• Question 17: Photosynthesis stores energy in the form of glucose. It uses light energy to convert inorganic molecules (\(CO_2\) and \(H_2O\)) into organic glucose.
• Question 18: Cellular respiration produces energy in the form of ATP. Although photosynthesis also produces some ATP during the light - dependent reactions, its main purpose is to store energy in glucose. Cellular respiration's main goal (in terms of energy) is ATP production.
• Question 19: In photosynthesis, plants take in carbon dioxide (\(CO_2\)) from the atmosphere through stomata (small openings on the leaf surface). They use \(CO_2\) as a carbon source for making glucose. As a by - product of the light - dependent reactions (splitting of water), oxygen (\(O_2\)) is released back into the atmosphere through the stomata.

Answer:

1. Autotrophic organisms (plants, some algae, certain bacteria).
2. All living organisms.
3. Photosynthesis: chloroplasts (in plants/algae); Cellular respiration: mitochondria (in eukaryotes), cell membrane/cytoplasm (in prokaryotes).
4. Formula: \(6CO_2 + 6H_2O+light\ energy

ightarrow C_6H_{12}O_6 + 6O_2\); Reactants: \(CO_2\), \(H_2O\); Products: \(C_6H_{12}O_6\), \(O_2\).

1. Formula: \(C_6H_{12}O_6+6O_2

ightarrow 6CO_2 + 6H_2O+energy\); Reactants: \(C_6H_{12}O_6\), \(O_2\); Products: \(CO_2\), \(H_2O\), energy.

1. Photosynthesis.
2. Cellular respiration.
3. Plants take in \(CO_2\) (for glucose synthesis) and release \(O_2\) (by - product of water splitting) through stomata.
