Hello, nature-loving friends! Have you ever wondered why some plants have flowers and others don’t? Let’s explore this fascinating world together! We can group plants into two main types: non-flowering plants, called cryptogams, and flowering plants, called phanerogams. Let’s dive into each of these groups to learn more!
First, let’s talk about cryptogam plants. These are the plants that don’t have flowers. One interesting thing about cryptogams is that their parts, like roots, stems, and leaves, are not very well developed. They reproduce in a special way called asexual reproduction, using something called spores. Spores are tiny cells that can grow into new plants all by themselves, without needing another plant. Some examples of cryptogams are mosses and ferns. Have you ever seen them in a shady forest?
Now, let’s move on to phanerogam plants. These are the plants that have flowers. They usually reproduce in a way called sexual reproduction, which means they need both a male and a female cell to create seeds. But what are seeds? Seeds are small parts of the plant that contain a tiny baby plant, or embryo, ready to grow into a new plant.
There are two types of phanerogams: gymnosperms and angiosperms. Gymnosperms have flowers that are not very noticeable, like those on fir or pine trees. Their seeds are often found in cones, like the pine cones you might see in parks or forests.
On the other hand, angiosperms have bright and beautiful flowers, like those on almond trees. Their seeds are found inside fruits as they grow. Have you ever eaten an apple or a cherry? Those are fruits from angiosperm plants!
Wow, we’ve learned a lot about plants today! Now you know which plants have flowers and which don’t. Next time you’re outside, see if you can spot the different types of plants. Isn’t nature amazing?
We’ve had so much fun learning together! If you want to discover even more, there are many more videos and resources out there. Keep exploring and enjoying the wonders of nature!
Plant Detective Adventure: Next time you go for a walk in a park or garden, become a plant detective! Look around and try to find examples of cryptogams and phanerogams. Can you spot any mosses or ferns? How about flowering plants like roses or daisies? Draw a picture of each plant you find and label them as either cryptogam or phanerogam. Share your drawings with your friends or family and see if they can guess which plants you found!
Seed Sorting Challenge: Gather different seeds from fruits you eat at home, like apple seeds, cherry pits, or even sunflower seeds. With the help of an adult, carefully open the fruits to collect the seeds. Once you have a collection, sort them into two groups: seeds from gymnosperms (like pine cones) and seeds from angiosperms (like apples and cherries). Discuss with your family why these seeds belong to each group and what kind of plants they will grow into.
Spore Experiment: If you can find a fern or moss, gently collect a small piece with the help of an adult. Place it in a clear container with a little bit of water and cover it with a lid. Put the container in a warm, shady spot and observe it over a few days. Watch for tiny new plants growing from the spores! Draw what you see each day and write a short story about the journey of a spore turning into a new plant.
Sure! Here’s a sanitized version of the transcript:

Hello, nature-loving friends! Have you ever wondered why some plants have flowers and others don’t? Come with me, and let’s find out! We can classify plants into two types: non-flowering plants, called cryptogams, and flowering plants, called phanerogams. I’ll tell you about both of them in more detail.
Let’s start by talking about cryptogam plants, which are non-flowering plants. Their main characteristic is that we cannot easily distinguish the components that are part of them; that is, the roots, stems, and leaves are not very well developed. They reproduce asexually by means of spores. Spores are reproductive cells that do not need to be fertilized by another plant. Some examples of cryptogams are mosses and ferns.
Now we’ll 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. These types of plants always reproduce by seeds. But what exactly are 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 in 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. Look at how beautiful they are!
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!
