Question

6 Legumin Answer the following questions in brief. 1 What is the role of stomata in photosynthesis? 2. How do leguminous plants replenish the soil? 3. Differentiate between parasitic and saprophytic plants. 4. What is the difference between a complete parasite and a partial parasite? Give examples of each. 5. Which organisms have a symbiotic relationship to form lichens?​

Answer 1

Answer:

• Stomata facilitate carbon dioxide uptake and release of oxygen during the process of photosynthesis.
• Leguminous plants replenish the soil by the presence of Rhizobium. These plants contain legumes and nodules which reside in the bacteria called rhizobium. These bacteria convert the atmospheric nitrogen into a soluble form that can be absorbed by roots.
• Parasites are those organisms which obtain their nutrition from other living organisms, whereas saprophytes obtain their nutrition from the dead decaying organic matter.
• The main difference between total parasite and partial parasite is that the total parasite totally depends on the host for its growth, survival, and reproduction whereas the partial parasite depends on the host only for a certain requirement of their life such as water and shelter.

Answer 2

Answer:

1.Stomata facilitate carbon dioxide uptake and release of oxygen during the process of photosynthesis

2.Leguminous crops have root nodules which contain Rhizobium bacteria that can convert nitrogen gas of air into nitrates. These nitrates mix with the soil and enrich it. Thus, the soil in the soil gets enriched with nitrogen compounds.

3.Parasites are those organisms which obtain their nutrition from other living organisms, whereas saprophytes obtain their nutrition from the dead decaying organic matter.
