Nutrients are taken up by plants through their roots via a process called absorption. The plant’s root hairs increase the surface area available for nutrient absorption, and the nutrients are then transported through the plant’s vascular system to where they are needed for growth and development.

Nutrients are essential for the growth and development of plants, and they are taken up by the plant through the roots via a process known as absorption. The root system of a plant plays a crucial role in nutrient uptake as it is responsible for anchoring the plant in the soil and absorbing water and minerals.
One fascinating aspect of nutrient absorption is the presence of root hairs, which greatly increase the surface area available for nutrient uptake. These tiny hair-like structures extend from the surface of the root and are covered in microscopic projections called epidermal cells. This intricate network of root hairs enables the plant to efficiently absorb nutrients from the surrounding soil.
Once the nutrients are in contact with the root hairs, they pass through the cell walls of the epidermal cells and enter the root cortex. From here, they can either move directly into the plant’s vascular system or be stored in specialized cells within the root for later use. The vascular system of a plant, composed of xylem and phloem tissues, provides a means for the transport of nutrients throughout the plant.
As the plant grows and develops, it requires different nutrients in varying quantities. This selective uptake of nutrients is controlled by various factors, including the concentration of nutrients in the soil, the type of soil, and the metabolic needs of the plant. Interestingly, plants have evolved mechanisms to adjust nutrient uptake based on their requirements, ensuring they receive an optimal balance of essential elements.
In the words of American botanist Liberty Hyde Bailey, “A garden requires patient labor and attention. Plants do not grow merely to satisfy ambitions or to fulfill good intentions. They thrive because someone expended effort on them.”
Here are some interesting facts about nutrient uptake in plants:
- The primary macronutrients required by plants are nitrogen (N), phosphorus (P), and potassium (K), while secondary macronutrients include calcium, magnesium, and sulfur.
- In addition to macronutrients, plants also require micronutrients such as iron, copper, zinc, and manganese, among others, although they are needed in smaller quantities.
- Some plants have evolved symbiotic relationships with beneficial soil microorganisms, such as mycorrhizal fungi, which enhance nutrient uptake by extending the root system and facilitating nutrient exchange between the plant and the soil.
- The pH level of the soil plays a crucial role in nutrient availability. Different nutrients are more readily absorbed by plants at specific pH levels, with slightly acidic to neutral soils often being optimal for nutrient uptake.
- Water movement through the soil, driven by factors like temperature and gravitational forces, also affects nutrient availability and uptake, as nutrients dissolve in water and are transported along with it.
Table:
Factors affecting nutrient uptake in plants:
Factor | Effect
Soil pH | Influences nutrient availability
Root hairs | Increased surface area for nutrient absorption
Soil type | Varies in nutrient content and structure
Vascular system | Transports nutrients throughout the plant
Concentration | Selective uptake based on nutrient concentration
Soil microorganisms | Enhance nutrient uptake through symbiotic relationships
Water movement | Affects nutrient dissolution and availability
In conclusion, the process of nutrient uptake in plants is a complex and fascinating mechanism that ensures their proper growth and development. Through root absorption, with the aid of root hairs and the plant’s vascular system, essential nutrients are acquired from the soil in varying quantities to meet the metabolic needs of the plant. Understanding nutrient uptake is crucial for cultivating healthy and thriving plants.
Video answer to your question
This video discusses the significance of nutrients in the growth of plants, which primarily make their own food via photosynthesis but still require macronutrients such as nitrogen, magnesium, potassium, and phosphorus from the soil to produce essential components like proteins and chlorophyll. Failure to obtain these elements can result in issues such as stunted growth, yellowed or shriveled leaves, and deficient photosynthesis. Additionally, the video emphasizes the importance of proper nutrient provision for farmers who wish to maximize their crop harvests, and it covers techniques such as hydroponics and fertilizers that can be used to achieve this goal.

Plants take up essential elements from the soil through their roots and from the air through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.
Plants typically take in nutrients through their roots. The roots absorb water and minerals from the soil and transport them to the rest of the plant. The roots can also absorb nutrients from the air and water. The process of roots taking in nutrients is called absorption.

Also Know, What are 3 ways plants uptake nutrients? Answer will be: Root nutrient uptake and transport through the roots can occur by (i) diffusion, (ii) advection, and (iii) active uptake.
Herein, How are nutrients taken up by the plants Class 7? Plants absorb nutrients and water through their roots, but photosynthesis — the process by which plants create their fuel — occurs in the leaves. Therefore, plants need to get fluids and nutrients from the ground up through their stems to their parts that are above ground level. Was this answer helpful?
How are most nutrients absorbed in a plant?
Answer to this: Most nutrients are absorbed through root hairs near the very tip of the roots. Root hairs are ultra-fine roots that have a large surface area, allowing them to absorb even more water. The majority of plants also partner with different fungi to absorb even more nutrients from the water in the soil.
Considering this, How do plants absorb and transport nutrients?
As an answer to this: Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of "transport" tissues in plants- xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.
Also asked, Do plants really need nutrients? Answer: Plants need to be fertilized because most soil does not provide the essential nutrients required for optimum growth. Even if you are lucky enough to start with great garden soil, as your plants grow, they absorb nutrients and leave the soil less fertile. It took nutrients from the soil to build those plant tissues.
Also asked, Do Plants take nutrients from the soil or just water?
Response to this: Plants draw water and dissolved nutrients up from the soil through their roots, and control where they go throughout the plant by opening and closing those tiny stomata. The sticky nature of water molecules moves nutrients throughout the plant, but plants cannot live on air and water alone.
Can plants survive without nutrients? The answer is: Can plants survive without nutrients? Answer: Yes, plants can grow without soil, but they cannot grow without the necessities that soil provides. Plants need support, nutrients, protection from adverse temperatures, an even supply of moisture, and they need oxygen around the roots. …
