Answer 2

Photosynthesis and Plant Nutrition

1. Only plants can absorb energy from solar radiation. This statement is true. Plants have specialized structures called chloroplasts that contain chlorophyll, a pigment that enables them to capture energy from sunlight and convert it into chemical energy through the process of photosynthesis. [[1]]

2. Plants obtain nutrition by consuming inorganic substances. This statement is false. Plants are autotrophs, meaning they can produce their own food through photosynthesis. They use sunlight, carbon dioxide, and water to synthesize organic compounds, such as glucose, which serve as their source of nutrition. [[2]]

3. In a forest, mineral salts absorbed by plants are returned to the soil through fallen leaves and needles. This statement is true. When plants shed their leaves and needles, the organic matter decomposes, releasing mineral salts back into the soil. This process is known as nutrient cycling and is essential for maintaining the fertility of the soil. [[3]]

4. Chlorophyll in leaves converts carbon dioxide and water into organic substances. This statement is true. Chlorophyll, located in the chloroplasts of plant cells, enables the process of photosynthesis. In the presence of sunlight, chlorophyll molecules absorb energy, which is used to convert carbon dioxide and water into glucose and oxygen. This process occurs in the leaves of plants. [[4]]

5. Green plants absorb solar energy and convert it into chemical energy. This statement is true. Through the process of photosynthesis, green plants capture solar energy and convert it into chemical energy stored in the form of glucose and other organic compounds. This energy is used by plants for growth, reproduction, and other metabolic processes. [[5]]

6. The appearance of green plants on Earth led to the formation of atmospheric oxygen. This statement is true. The evolution of photosynthetic organisms, including green plants, played a crucial role in the production of atmospheric oxygen. Through photosynthesis, plants release oxygen as a byproduct, which gradually accumulated in the atmosphere, leading to the oxygen-rich environment we have today. [[6]]

Respiration and Metabolism in Plants

7. Respiration involves the breakdown of complex organic substances into simpler inorganic compounds, releasing energy from chemical bonds. This statement is true. Respiration is a metabolic process in which organic compounds, such as glucose, are broken down into simpler inorganic compounds, such as carbon dioxide and water. This process releases energy stored in the chemical bonds of the organic substances. [[7]]

8. Metabolism in plants includes both nutrition and respiration. This statement is true. Metabolism in plants encompasses various processes, including photosynthesis (nutrition) and respiration. Photosynthesis involves the synthesis of organic compounds using sunlight, while respiration involves the breakdown of organic compounds to release energy. Both processes are essential for the plant's growth and survival. [[8]]

Plant Reproduction

9. Vegetative propagation is only characteristic of flowering plants. This statement is false. Vegetative propagation, which involves the production of new plants from vegetative structures like stems, roots, or leaves, is not limited to flowering plants. Many non-flowering plants, such as ferns and mosses, can also reproduce vegetatively. [[9]]

10. Apple trees can only be propagated through grafting. This statement is false. While grafting is a common method of propagating apple trees, they can also be propagated through other means, such as seed germination or cuttings. Grafting is often preferred because it allows for the reproduction of specific apple varieties with desired traits. [[10]]

11. Sexual reproduction involves fertilization. This statement is true. Sexual reproduction in plants involves the fusion of male and female gametes, resulting in the formation of a zygote. This process requires the transfer of pollen from the male reproductive organs to the female reproductive organs, leading to fertilization and the development of seeds.
