Hey there! Today, we’re going to dive into the amazing world of photosynthesis. This is a special process that plants use to make their own food. It’s like a magical recipe where plants turn water, sunlight, and carbon dioxide into oxygen, which we all need to breathe!
The journey of photosynthesis begins when plants soak up water and minerals from the soil through their roots. This mixture is called raw sap. The raw sap travels up from the roots through the stem and reaches the leaves with the help of special tubes called xylem.
Plants also take in carbon dioxide from the air through tiny openings on their leaves called stomata. Inside the leaves, there are special parts called chloroplasts, which contain a green pigment known as chlorophyll. This is what makes plants look green and helps them capture sunlight.
Photosynthesis needs three main ingredients: sunlight, raw sap, and carbon dioxide. When these come together, the raw sap turns into something called elaborated sap. This new sap is spread throughout the plant by another set of tubes called phloem, and during this process, oxygen is released into the air.
Remember, photosynthesis only happens during the day because plants need sunlight to make it work. So, when the sun is shining, plants are busy making food and releasing oxygen!
It’s important not to mix up photosynthesis with respiration. While photosynthesis happens only during the day, plants breathe both day and night. They take in oxygen and let out carbon dioxide, just like we do.
Plants are super important for our planet. They help keep the air clean and provide us with the oxygen we need to live. So, it’s really important to take care of plants and respect them.

Leaf Observation Journal: Go outside and find a plant or tree. Look closely at the leaves and try to spot the tiny openings called stomata. Use a magnifying glass if you have one! Draw a picture of the leaf in your journal and write down what you see. Do you notice any changes in the leaves at different times of the day? Record your observations and think about how sunlight might be affecting the plant.
Photosynthesis Role Play: Gather some friends or family members and act out the process of photosynthesis. Assign roles like the sun, water, carbon dioxide, chlorophyll, and oxygen. Use props like a flashlight for the sun and a watering can for water. As you act out the process, talk about how each part contributes to making food for the plant and releasing oxygen. This activity will help you remember the steps of photosynthesis in a fun way!
Sunlight Experiment: Take two small plants and place one in a sunny spot and the other in a shaded area. Water them regularly and observe what happens over a week. Which plant looks healthier and why do you think that is? Write down your thoughts and discuss how sunlight plays a role in photosynthesis and plant health.

Today, we’re going to learn about photosynthesis. 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 right here in the leaves is where photosynthesis actually takes place. Leaf cells are made up of chloroplasts, which contain a pigment called chlorophyll. Chlorophyll gives plants their green color. Chloroplasts capture light energy.
Photosynthesis involves sunlight, raw sap, and carbon dioxide. 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.

Don’t confuse respiration with photosynthesis. Plants breathe during the day and night; they absorb oxygen and release 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.
