Respiration In Plants

To solve this question, we must identify the organelle where energy is stored during cellular respiration.

1. Understanding Cellular Respiration:
Cellular respiration is the process by which cells produce energy (ATP) by breaking down glucose molecules. This occurs predominantly within mitochondria.

2. Analyzing the Options:
- Golgi complex: Involved in packaging and transport of proteins, not energy production.
- Mitochondria: Known as the "powerhouses" of the cell, they generate and store energy in the form of ATP.
- Nucleus: Controls genetic material and cell activities, but not involved directly in ATP production.

3. Identifying the Correct Answer:
The correct cell organelle associated with energy storage during cellular respiration is mitochondria.

Final Answer:
Option (B) Mitochondria is correct.

To solve the problem, we need to determine which structure mangrove plants use for respiration.

1. Understanding Mangrove Adaptations:
Mangrove plants grow in swampy and saline coastal regions where the soil is often waterlogged and lacks oxygen. To cope with these conditions, mangroves have evolved specialized structures called aerial roots (also known as pneumatophores).

2. Function of Aerial Roots:
These aerial roots: - Grow upwards from the underground root system
- Emerge above the water or soil surface
- Contain small pores called lenticels to absorb oxygen directly from the atmosphere

3. Elimination of Other Options:
- Tap root: Main root system for anchorage, not respiration.
- Rhizoids: Found in non-vascular plants like mosses, not mangroves.
- Scales: Protective structures, not involved in respiration.

Final Answer:
Mangrove plants respire with their .

To solve the problem, we need to identify the part of the plant where lenticels — the respiratory organs — are located.

1. Understanding Lenticels:
Lenticels are small, spongy openings found on the surface of the plant's organs that allow for gaseous exchange. They function as respiratory structures in plants and are crucial for the exchange of oxygen and carbon dioxide with the atmosphere.

2. Location of Lenticels:
Lenticels are primarily found on the stem and sometimes on fruits. They are especially visible on woody stems and provide a means of aeration for the internal tissues.

Final Answer:
Lenticels are present in the stem part of the plant.
