The main life processes in plants include growth, nutrition, respiration, transportation, and reproduction.

Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.

Plants absorb sunlight, carbon dioxide from the air, and water from the soil.

The leaves of the plant are the primary site for photosynthesis.

Starch is a carbohydrate that plants produce and store as food, formed during photosynthesis.

Stomata are tiny pores on leaves that allow for gas exchange; they facilitate the intake of carbon dioxide and the release of oxygen.

Xylem transports water and minerals from the roots to the rest of the plant, while phloem carries food produced by photosynthesis from the leaves.

The word equation for photosynthesis is: Sunlight + Carbon Dioxide + Water → Glucose + Oxygen.

Sunlight and water are two essential substances for plant growth.

Water is crucial for photosynthesis, nutrient transportation, and maintaining plant structure through turgor pressure.

Plants grow by cell division and expansion, which leads to increases in height, thickness, and the development of new leaves and branches.

In the absence of sunlight, plants cannot perform photosynthesis effectively, leading to stunted growth and potential death.

Respiration in plants is the process of breaking down glucose into energy, carbon dioxide, and water.

Roots absorb water and essential minerals from the soil, supporting nutrition and stability for the plant.

Plants store food primarily as starch.

The leaf functions as the main site of photosynthesis, converting sunlight into chemical energy.

Lack of water can lead to wilting, reduced growth, and eventually death due to inability to maintain turgor pressure.

The iodine test is used to detect starch; if starch is present, the leaf changes color to blue-black.

Destarching is the process of removing stored starch from plants, usually done by keeping them in the dark.
