Structure refers to something's form, makeup, or arrangement. Function refers to something's job, role, task, or responsibility.
What is the function of a plant for kids?
The plant's stem transports the nutrients and minerals through the plant up to the leaves. The leaves are the location for photosynthesis. After photosynthesis occurs, the stem is responsible for carrying the food through the rest of the plant.
What is the structure of a leaf?
A leaf usually has a large surface area, so that it can absorb a lot of light. Its top surface is protected from water loss, disease and weather damage by a waxy layer. The upper part of the leaf is where the light falls, and it contains a type of cell called a palisade cell. This is adapted to absorb a lot of light.
What is an example of structure and function?
This fundamental physical relationship (a relationship between structure and function) can then be applied to a number of other phenomena. For example, the movement of oxygen and carbon dioxide in the lungs and in the tissues must meet the metabolic needs of the body.
What are the three functions of a structure?
Functions of Structurea) to support - the legs of a chair are designed to support the weight of the user and chair;b) to contain - the shell of an egg is meant to contain and protect the inside of the egg;c) to protect - the helmet is designed to protect the user's head;More items...
What is the structure and function of an organism?
The bodies of organisms are organized into functional systems—cells are organized into tissues, and tissues are organized into organs. Body systems carry out critical functions, such as locomotion, reproduction, digestion, and circulation.

What are the functions of roots?
Roots are the part of a plant that are buried in the soil. They grow out of the seeds during the germination. Roots perform very important tasks, which include: 1 Absorbing the water and the necessary nutrients and sending them to different parts of the plant. 2 It provides a good grip to the stem of a plant so that it can stand against the wind. 3 Some plants store the food in their roots. Examples of these plants are carrots and potatoes.
How do plants produce food?
They produce the food for the whole plant by the process of photosynthesis. In photosynthesis, plants take the carbon dioxide from the air and light from the Sun to make food. Also, they produce oxygen for us to breathe.
What do flowers do?
Flowers have beautiful colors with attractive fragrance. They play an important role in the reproduction of the flowering plants. They also make the seeds and the fruits of a plant.
Why do plants grow out of seeds?
They grow out of the seeds during the germination. Roots perform very important tasks, which include: Absorbing the water and the necessary nutrients and sending them to different parts of the plant. It provides a good grip to the stem of a plant so that it can stand against the wind. Some plants store the food in their roots.
What does a stem do to a plant?
Stem performs functions, which include: It provides support to the leaves, flowers, and fruits. It carries the water and nutrient absorbed by the roots to all parts of a plant.
What is the purpose of fruit?
Fruits are the parts of plants that bear its seeds. The fruits are made when the female part of the flower are pollinated. Making delicious fruits is the strategy used by plants to disperse it seeds to different locations. Because fruits are delicious, when animals are humans eat them they will through its seeds to land.
Why do flowers have a good smell?
Fun Facts. Flowers have eye-catching colors and good smell to attract the insects and animals to carry their pollen. Humans use around 2000 different species of plant in their food. Some plants eat insects as their food. These plants are called carnivorous plants. Cite this Page. Abdul Wahab, "Plant Structure," in Science4Fun, July 23, 2021, ...
Why are plants important?
Plants are an important part of human life and vegetation as well. They are very beneficial to us and give us a lot of things. We are surrounded by plants, but have you ever stopped to notice the parts of a plant? All parts of plants are important and carry out different functions. All of them come together to perform their respective functions ...
Why do plants have leaves?
The leaves of the plant help in photosynthesis. Moreover, they help in removing any excess water via stomata. In short, it is for transpiration. Moreover, some plants have leaves which also assist in the process of reproduction. Thus, leaves perform a number of functions, which helps the plant grow healthier.

Why are plants specialized?
Cells of a matured and higher plant become specialized to perform certain vital functions that are essential for their survival. Few plant cells are involved in the transportation of nutrients and water, while others for storing food.
What is the function of the cell wall?
The primary function of the cell wall is to protect and provide structural support to the cell. The plant cell wall is also involved in protecting the cell against mechanical stress and to provide form and structure to the cell. It also filters the molecules passing in and out of the cell. The formation of the cell wall is guided by microtubules.
Why are plant roots more rigid than collenchyma cells?
These cells are more rigid compared to collenchyma cells and this is because of the presence of a hardening agent. These cells are usually found in all plant roots and mainly involved in providing support to the plants.
