The plant cell is the fundamental living unit and smallest structure of all plants. Its dimensions and form vary based on its function. It consists of several organelles that play essential roles in its operation.
The correct answers are: (refer to the numbers in the image).
1 corresponds to a vacuole.
2 corresponds to the cell wall (if you examine closely, the arrow points to the green layer, while the yellow layer is the cell membrane).
3 corresponds to a chloroplast.
4 corresponds to mitochondria.
Biotic refers to living entities, while abiotic denotes non-living ones.
Answer:
Explanation:
For approximately 250 years, or two and a half centuries, there has been a rapid consumption of fossil fuels to satisfy human demands. These fossil fuels release significant quantities of carbon dioxide when combusted. As a result of burning these resources in factories, power plants, vehicles, and more, carbon is emitted into the atmosphere. Carbon dioxide acts as a greenhouse gas, which leads to the trapping of heat and an increase in global temperatures.
It's projected that nearly 5.5 billion tons of carbon dioxide are emitted annually due to fossil fuel combustion. This vast quantity is overwhelming for plants to convert into oxygen through photosynthesis, causing an imbalance in the carbon cycle. Consequently, more carbon dioxide is produced than can be absorbed, ultimately contributing to a rise in the planet's temperature as the excess carbon dioxide captures additional sunlight.
Invasive species negatively impact wildlife in various ways. When an assertive non-native species enters an ecosystem, it often lacks natural predators or methods of control.... Such species can disrupt the food web by eliminating or replacing indigenous food sources.

Answer:
Ethylene. (Ans. D)
Explanation:
Ethylene controls the aging and ripening processes in plants. While many fruits and vegetables generate small amounts of ethylene, climacteric fruits like bananas produce larger quantities. This ethylene release accelerates respiration, triggers more ethylene production, and causes changes in color and flavor.
Therefore, when transporting green bananas over long distances to stores, the ethylene gas should be removed from their surrounding environment.
