Making Plant Food Chapter 19

Chlorophyll is a green pigment found in the leaves of plants. It is responsible for the absorption of light energy during photosynthesis, the process by which plants convert sunlight into chemical energy. Chlorophyll plays a crucial role in capturing sunlight and converting it into usable energy for the plant's growth and development. It gives plants their characteristic green color and is essential for their survival and the production of oxygen.

The correct answer is plants. Plants are the primary source of food for humans. They provide us with fruits, vegetables, grains, and other plant-based products that form a major part of our diet. Plants convert sunlight into energy through photosynthesis and produce nutrients that are essential for our survival. Without plants, our food supply would be severely limited, making it impossible for humans to survive.

Plants produce their own food through a process called photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide, and water to convert them into glucose (energy) and oxygen. This process takes place in the chloroplasts of plant cells, where chlorophyll, a green pigment, captures sunlight energy. Therefore, the correct answer is photosynthesis.

Plants release oxygen into the air through a process called photosynthesis. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose (a type of sugar) and oxygen. The oxygen produced by plants is then released into the atmosphere as a byproduct. This oxygen is essential for the survival of many organisms, including humans, as it is needed for respiration.

Plants collect nutrients and minerals from the soil and through their roots. The roots of plants have tiny root hairs that absorb water and nutrients from the soil. These nutrients are essential for the growth and development of plants. While rainwater and sunlight are important for plants, they do not directly provide nutrients and minerals. Therefore, plants primarily rely on the soil and their root system to collect the necessary nutrients for their survival and growth.

Plants need chlorophyll, light, water, carbon dioxide, and nutrients to make their food through the process of photosynthesis. Chlorophyll is a pigment that captures sunlight, which is essential for the conversion of carbon dioxide and water into glucose and oxygen. Water is necessary for transporting nutrients and maintaining cell structure. Carbon dioxide is used as a source of carbon for building glucose molecules. Nutrients, such as nitrogen, phosphorus, and potassium, are required for plant growth and development.
