Jackfruit Fruit Structure and Key Features Explained
Welcome, young science explorers! Are you ready to discover the world’s largest fruit that grows on a tree? Let’s go on a tropical adventure and meet a giant superstar of the plant kingdom—the jackfruit plant!
Say Hello to the Jackfruit Plant!
A True Giant with a Sweet Secret
The jackfruit plant’s official name is Artocarpus heterophyllus. It belongs to the Moraceae family, making it a cousin of mulberries and breadfruit. This gigantic tree originally comes from the warm, wet forests of South and Southeast Asia, especially the Western Ghats of India. Some jackfruit trees can grow taller than a two-story house!
Where Does It Grow?
Jackfruit loves hot, humid places with lots of rain. If winters are frost-free, like in parts of southern India or Florida, you might spot a jackfruit tree happily growing.
What Are the Parts of a Jackfruit Plant?
From Roots to the Mighty Fruit
Let’s peek at each part of this amazing plant to see what makes it unique:
- Roots: Thick taproots hold the tree steady, helping it suck up water from deep down.
- Stem: Jackfruit has a strong, woody trunk with many spreading branches. This is what makes it so sturdy.
- Leaves: Its leaves are glossy, leathery, and dark green. Young leaves sometimes look lobed (like fingers), while adult leaves are smooth and simple.
- Flowers: The plant makes two types of tiny flowers—male and female—bunched together on the same tree. These grow right out of the trunk and big branches, a trick called ‘cauliflory’.
- Fruit: The star of the show! Jackfruit is giant—sometimes weighing more than a little kid (up to 50 kg). It’s a ‘multiple’ or ‘compound’ fruit, meaning it’s made from many tiny flowers fused into one spiky, green-to-yellow package.
- Seeds: Big and oval, jackfruit seeds are edible and tasty when roasted or boiled, full of healthy protein and starch.
Table: Super Jackfruit Plant Parts
| Plant Part | How It Looks/Works |
|---|---|
| Roots | Strong taproots for support and water |
| Stem | Woody, thick trunk, many branches |
| Leaves | Shiny, thick, oval, dark green |
| Flowers | Tiny, both male and female, cauliflorous |
| Fruit | Multiple, huge, yellow-green, bumpy skin |
| Seeds | Oval, smooth, starchy, edible |
How Does the Jackfruit Plant Live, Breathe, and Grow?
The Plant’s Tree Tricks
The jackfruit plant uses photosynthesis—taking in sunlight, water, and air—to make food and grow extra tall. It’s a master at picking warm, humid places and growing fruits right on its trunk and thick branches. Jackfruit trees can live for decades and make fruit year after year!
How Long Does Jackfruit Take to Fruit?
From seed, jackfruit trees usually take 3–8 years to fruit. Grafted ones may fruit sooner, in just 3–4 years.
How Do Jackfruit Plants Reproduce?
Jackfruit relies on insects to spread pollen from flower to flower on the same tree. After that, the female flowers turn into the lump of fruit. Wild animals like monkeys help spread the seeds to new places (a process called ‘zoochory’).
Why Are Jackfruit Plants So Special Everywhere?
Food, Medicine, and Even Wood!
- Tasty fruit: Ripe jackfruit is sweet, juicy, and smells amazing. Unripe jackfruit can be cooked just like a vegetable—so yummy!
- Seeds for snacks: Once boiled or roasted, the big seeds are soft and nutty and have lots of protein.
- Good for you: Jackfruit is packed with vitamin C, A, potassium, and special plant antioxidants that keep our bodies healthy.
- Strong wood: The golden wood is great for making furniture and musical instruments.
- Traditional medicine: Some people use jackfruit to help digestion and boost immunity (though always ask a doctor first!).
- Eco-friend: Big trees give shade and food to lots of forest animals.
Does It Grow in the USA?
Jackfruit can live in warm, frost-free spots like southern Florida, California, Hawaii, or parts of Texas. But it needs care and cannot survive cold winters.
Jackfruit, Mango, or Breadfruit – Which Is Which?
Spot the Difference!

| Family | Moraceae | Anacardiaceae | Moraceae |
| Fruit Size | Huge (up to 50 kg!) | Medium | Medium |
| Seed Edible? | Yes | Yes (kernel) | Usually no |
Quick Jackfruit Facts Table
| Feature | What It Means | Fun to Know |
|---|---|---|

Don’t Get Mixed Up! Common Exam Doubts
- Jackfruit is a ‘multiple fruit’, but mango is a ‘simple, fleshy drupe’. Don’t mix up their fruit types!
- Both breadfruit and jackfruit belong to Moraceae, but only jackfruit gets truly giant.
- Remember: Unripe jackfruit is a veggie; ripe is a fruit. Both are delicious.
- Jackfruit grows right out of the trunk—a rare plant trick called ‘cauliflory’.
