Did you know that plants can make their own food? This amazing process is called photosynthesis. During photosynthesis, plants use water, sunlight, and carbon dioxide to create oxygen and food. It all starts when plants absorb water and minerals from the soil through their roots. This mixture is called raw sap. The raw sap travels up the plant through special tubes called xylem, reaching the leaves where the magic happens.
The leaves have tiny openings called stomata that take in carbon dioxide from the air. Inside the leaves are cells with chloroplasts, which contain a green pigment called chlorophyll. Chlorophyll captures sunlight, which is essential for photosynthesis. As the process continues, the raw sap turns into elaborated sap, which spreads throughout the plant using another set of tubes called phloem. This is when oxygen is released into the air. Remember, photosynthesis only happens during the day because plants need sunlight to make food.
Plants are super important for our planet. They help clean the air we breathe by taking in carbon dioxide and releasing oxygen. So, it’s important to take care of plants and respect them because they are the backbone of life on Earth.
Let’s explore the different parts of a plant. The roots are hidden underground. They hold the plant in place and absorb water and nutrients from the soil. The stem supports the plant and acts like a highway, transporting water and food from the roots to the rest of the plant. Some stems are green and flexible, while others are hard and woody, like tree trunks.
The leaves are usually green because of chlorophyll. They are attached to the stem and are where photosynthesis takes place. Leaves also help the plant breathe. In autumn, when there’s less light, the chlorophyll fades, and leaves change color to yellow or brown. Leaves have two main parts: the petiole, which connects the leaf to the stem, and the blade, which is the flat part that makes food for the plant.
Have you ever noticed that some plants have flowers while others don’t? Plants can be grouped into two main types: non-flowering plants, called cryptogams, and flowering plants, called phanerogams.
Cryptogams are plants that don’t have flowers. Their roots, stems, and leaves are not very developed. They reproduce using spores, which are tiny cells that don’t need another plant to grow. Examples of cryptogams include mosses and ferns.
Phanerogams are plants that have flowers. They reproduce using seeds, which need both male and female cells to grow into new plants. There are two types of phanerogams: gymnosperms and angiosperms.
Gymnosperms have small, often unnoticed flowers, like those on pine trees. Their seeds are found in structures like pine cones. Angiosperms, on the other hand, have bright and colorful flowers, and their seeds are inside fruits. An example of an angiosperm is the almond tree.
Now that we’ve learned about the different types of plants, can you spot them the next time you’re outside? Plants are fascinating, and there’s so much more to discover. Keep exploring and learning about the amazing world of plants!
Photosynthesis Experiment: Try a simple experiment to see photosynthesis in action. Take a small, clear plastic bag and gently place it over a leaf on a plant outside, sealing it with a twist tie. Leave it for a few hours on a sunny day. Check back later to see if there are tiny water droplets inside the bag. This is water vapor released during photosynthesis!
Plant Part Hunt: Go on a plant part scavenger hunt in your backyard or a nearby park. Look for different parts of plants such as roots, stems, leaves, and flowers. Draw or take pictures of each part you find and label them. Discuss with a friend or family member how each part helps the plant survive and grow.
Flowering vs. Non-Flowering Plants: Create a simple chart with two columns labeled “Flowering Plants” and “Non-Flowering Plants.” As you explore your surroundings, note down examples of each type of plant you see. Discuss with a friend or family member how these plants might reproduce differently and why they are important to the ecosystem.

Photosynthesis is a process during which plants make their own food. During this process, plants transform water, sunlight, and carbon dioxide into oxygen. The photosynthesis cycle starts with plants absorbing water and mineral salts from the soil through their roots. This fluid mixture is called raw sap. Raw sap flows up the roots to the stem and travels through the rest of the plant to the leaves with the help of woody transport tissues called xylem. Carbon dioxide is absorbed through tiny pores called stomata, and photosynthesis actually takes place in the leaves. Leaf cells are made up of chloroplasts, which contain a pigment called chlorophyll. Chlorophyll gives plants their green color and captures light energy.
During photosynthesis, raw sap becomes elaborated sap, and living tissues called phloem spread elaborated sap to the rest of the plant. This is when oxygen is released. Keep in mind that photosynthesis happens only during the day because plants need sunlight.
During the day and night, plants breathe by absorbing oxygen and releasing carbon dioxide. Plants are really important for the planet; they are the backbone of life on Earth. Thanks to them, we breathe clean air because plants purify it. So now you know that you should respect and look after them.
Today, we’re going to learn about the parts of the plant. Their roots lie below the surface of the soil; they hold the plant together and absorb water and mineral salts. The stem holds up the plant and brings water and food straight from the roots to the rest of the plant. Green stems store nutrients during photosynthesis. Plant stems can grow into branches. Green stems are soft and flexible, while woody stems are hard and rigid; they are called trunks. Trees have trunks.
The leaves are green because of the pigment called chlorophyll, and they are attached to the stem. Photosynthesis happens in the leaves, which also help the plant breathe. Leaves differ in blade and form. In autumn, when light is scarce, chlorophyll levels drop, and leaves turn yellow or brown. Leaves are made up of two parts: the petiole and the blade. The blade is the flat part of the leaf that has many green food-making cells. The petiole attaches the leaf blade to the stem.
Flowering plants are also known as angiosperms. Flowers are the reproductive structures of the plant, and all fruits come from flowers, which contain seeds.
Have you ever wondered why some plants have flowers and others don’t? We can classify plants into two types: non-flowering plants called cryptogams and flowering plants called phanerogams.
Let’s start with cryptogam plants, which are non-flowering. Their main characteristic is that we cannot distinguish the components that are part of them; the roots, stem, and leaves are not very well developed. They reproduce asexually by means of spores, which are reproductive cells that do not need to be fertilized by another plant. Some examples of cryptogams are mosses and ferns.
Now, let’s talk about phanerogam plants, which are flowering plants. These plants usually reproduce sexually, meaning they require the joining of a female and a male reproductive cell. They always reproduce by seeds. Seeds are small pieces of material that contain the embryo used to create a new plant.
There are two types of phanerogams: gymnosperms and angiosperms. Gymnosperm plants have rather unnoticeable flowers, like those of a fir or pine tree. The seeds are arranged on both sides of an axis, like a pine cone. Perhaps you’ve seen them in parks and forests. In the case of angiosperm plants, the seeds are found inside the fruits during the maturation process. These plants have showy and eye-catching flowers, just like those of an almond tree.
What a great time we had together! We’ve learned which plants are flowering and non-flowering. Do you think you’ll be able to recognize the different plant types the next time you see them? Until next time!
