The following table provides the botanical names for a variety of familiar plants: 

Explanation

Angiosperms are flowering plants that produce seeds enclosed within a carpel/fruit.

In contrast, gymnosperms have naked seeds not enclosed by a fruit.

Explanation

Photosynthesis involves:

• Energy-Rich Carbohydrates are Synthesized: Photosynthesis is the process by which plants convert light energy into chemical energy, primarily in the form of glucose (a carbohydrate) and other sugars.
• CO₂ and H₂ of Water are Reactants: During photosynthesis, plants take in carbon dioxide (CO₂) from the atmosphere and water (H₂O) from the soil.
• The hydrogen from the water molecule is used in the synthesis of glucose.
• Chlorophyll Alone Converts Light Energy to Chemical Energy: Chlorophyll, the green pigment in plants, plays a crucial role in capturing light energy.
• This light energy is then converted into chemical energy, which powers the synthesis of glucose.

Explanation

Carbohydrates are made of C, H, and O, with hydrogen and oxygen in the ratio of 2:1, like water.

Example: Glucose (C₆H₁₂O₆) → H:O = 12:6 = 2:1.

Explanation

Protoplasm is the living content of a cell, including cytoplasm and nucleoplasm.

It is often called the “physical basis of life” because it carries out vital functions.

Explanation

Polio can be effectively prevented through vaccines: Oral Polio Vaccine (OPV) and Inactivated Polio Vaccine (IPV).

There is no cure or medication for polio, only prevention through immunization.
