English Vocabulary for Parts of a Plant

Have you ever wondered about the different parts of a plant and what they are called? Learning the vocabulary for parts of a plant is important because it helps us understand how plants grow and function. From the roots that anchor the plant to the leaves that absorb sunlight, each part has a specific role. By knowing these words, we can talk about plants, identify their different parts, and understand how they contribute to the beautiful world of nature. So, let’s explore the fascinating world of plants and their various parts!

Roots

1. Taproot (noun) /ˈtæp.ruːt/: This is the main, central root of a plant that goes straight down into the soil. It provides the plant with stability and takes in water and nutrients from deep within the soil.
