Welcome, little scientists! Ready to dig into the exciting world under the ground? Today we will explore a fascinating veggie called the turnip plant. From its round juicy roots to its cheerful flowers, let’s find out why this plant is a big star in biology books and in your kitchen too. Get set to meet the turnip plant and discover what makes it so special for students and exam toppers everywhere!
Say Hello to the Turnip – What’s in a Name?
Meet the Star: Brassica rapa subsp. rapa
The turnip plant has a scientific name: Brassica rapa subsp. rapa. It belongs to a big family called Brassicaceae, also known as the mustard or cabbage family. Turnip’s cousins include cabbage, mustard, and radish! Turnips love cool weather and are grown in fields all across Europe and Asia, but you can spot them in markets around the world.
Where Do Turnips Grow Best?
- Cool, moist soil is their favorite place to live.
- They grow as annuals (one year) or biennials (two years), depending on the weather.
- Found in fields, gardens, and sometimes as food for farm animals.
Turnip’s Family Traits
- Family: Brassicaceae (Mustard family)
- Has a swollen, globular root known as “napiform” (like a mini ball with a tail!)
- Often confused with radish or carrot, but turnip is unique!

Parts of a Turnip Plant – What’s Inside?
Let’s Start with the Root
- Root: The part you eat! It’s round and white or purple, with a skinny bottom. This is not a tuber like potato, but a special modified tap root that stores food.
- Storage: The root is full of sugars – plants store their lunch for later!
More Important Parts
- Stem: Very short, hidden at the base, just above the root.
- Leaves: Form a green rosette (circle shape) at the ground level. They’re simple and often a little hairy.
- Flowers: Tiny, usually yellow or white, with 4 petals shaped like a cross (“cruciform”).
- Fruit: Long, thin pod called a siliqua, which contains seeds.
The morphology of flowering plants helps us learn these cool parts in a scientific way!
How Does the Turnip Plant Live and Grow?
Plant Magic: Tricks for Survival
- Photosynthesis: Like all green plants, turnip leaves use sunlight to make food.
- Modified Root: The thick, swollen root stores sugar for the whole plant. This helps it survive cold winters or dry weather.
- Reproduction: Turnips make flowers that attract insects to spread their pollen, creating seeds in skinny pods.
Why Do Turnip Roots Look Like Balls?
Turnip roots swell up as they fill with sweet, starchy food. That’s why they look round and plump! The shape is called “napiform.” This storage makes turnip roots delicious and filling for humans and animals.
Turnip Power! Food, Medicine, and More
Why People Love Turnips
- Yummy Veggie: Cooked, roasted, or even raw – the root is tasty and healthy.
- Leafy Treat: Young turnip leaves can be eaten as “turnip greens.”
- Animal Food: Turnips are grown as food for farm animals too.
- Good for Health: Turnip roots give us vitamin C, fiber, and minerals. Some people even use them in traditional medicine!

Turnip vs Carrot vs Radish – Know the Difference!
Not All Roots Are the Same!
| Plant | Root Type | Family | Shape |
|---|---|---|---|
| Turnip | Napiform (ball-shaped) | Brassicaceae | Round, white/purple |
| Carrot | Conical tap root | Apiaceae | Orange, pointy |
| Radish | Fusiform (spindle) | Brassicaceae | White/red, long |
Don’t let the shapes confuse you! Even though these are all root veggies, only turnip is truly “ball-like.”
Turnip Fast Facts Table
| Feature | What It Means | Fun to Know |
|---|---|---|
| Scientific Name | Brassica rapa subsp. rapa | Shares family with cabbage & mustard! |
| Family | Brassicaceae | Known as “crucifers” |
| Edible Part | Swollen tap root | It’s NOT a tuber! |
| Flower Type | Cruciform (cross-shaped) | Has 4 petals arranged like a plus sign |
| Common Use | Eaten as vegetable | Also fed to cattle/sheep |
Fun Example: Can You Name This Root?
Q: A root is round like a ball, white and purple, with green leafy rosettes. Is it a turnip, carrot, or potato?
A: It’s a turnip! Potato is a stem tuber, and carrot is long and orange. Remember, turnip roots are napiform – nearly like a mini white ball with a leafy top.

Turnip Confusions – Don’t Get Tricked!
- Turnip vs. Potato: Potato is an underground stem (tuber), but turnip is a modified root.
- Turnip vs. Radish: Both are in the same family and have round roots, but turnip is usually bigger and has a smoother skin.
- Are turnip leaves edible? Yes! Especially when they are fresh and young.

FAQs on Turnip Plant: Morphology, Classification & Importance
1. What is the scientific name of turnip?
The scientific name of turnip is Brassica rapa subsp. rapa. Turnip belongs to the Brassicaceae (Cruciferae) family and is an important root vegetable covered in CBSE, ICSE, NEET, and IGCSE syllabi. This species is commonly studied under root modifications and plant classification topics for board exams.
2. Is turnip a root or stem tuber?
Turnip is a root tuber, specifically a modified tap root (napiform type). The edible part of turnip is the globular, fleshy tap root adapted for food storage. It is different from stem tubers such as potatoes, making it an important example in root modification questions for NEET and CBSE exams.
3. What part of turnip is edible?
The main edible part of the turnip is its modified tap root. Key points for students include:
- The root is swollen and napiform (globe-shaped).
- Young leaves of the turnip plant may also be eaten as leafy vegetables.
- This feature is important for NEET, CBSE, and ICSE exam questions on plant morphology.
4. What type of root modification is found in turnip?
Turnip shows a napiform type of tap root modification for storage. In this form, the root becomes almost spherical at the top and tapers abruptly, which serves for storing food – a crucial point in plant morphology for CBSE and NEET exams.
5. Which family does turnip belong to?
Turnip belongs to the Brassicaceae (Cruciferae) family. This family is characterized by:
- Tetramerous, actinomorphic flowers (four petals and sepals)
- Tetradynamous stamens (4 long + 2 short)
- Inflorescence usually racemose type
- Examples: Turnip, Mustard, Radish
6. What are the uses of turnip plant?
Turnip plant has several economic and medicinal uses:
- Edible root rich in carbohydrates and dietary fibre.
- Young, tender leaves can be used as leafy vegetables.
- Turnip is cultivated as livestock fodder.
- Contains vitamin C, potassium, and antioxidant compounds.
- Traditionally used in folk medicine for digestive benefits and anti-inflammatory properties.
7. How is turnip different from radish and carrot?
Turnip, radish, and carrot differ in morphology, family, and root type:
- Turnip: Modified napiform root, family Brassicaceae.
- Radish: Modified fusiform root, family Brassicaceae.
- Carrot: Modified conical root, family Apiaceae.
8. What is the inflorescence and flower structure of turnip plant?
Turnip has a racemose (corymbose) inflorescence with typical Cruciferae flowers:
- Inflorescence: Raceme or corymb.
- Flowers: Actinomorphic, tetramerous (4 petals and sepals).
- Stamens: Six (tetradynamous – 4 long + 2 short).
- Petals arranged in a cross (cruciform) pattern; usually yellow or white.
9. Why is turnip important in the biology syllabus for NEET and CBSE?
Turnip is important for NEET and CBSE as an example of root modification and plant family identification. Key exam topics include:
- Root modifications – napiform, storage roots
- Plant classification – Brassicaceae features
- Economic and medicinal uses
- Plant identification via diagrams
10. What are the main features of the Brassicaceae (Cruciferae) family?
Characteristic features of the Brassicaceae family include:
- Herbaceous plants with alternate, simple or lobed leaves forming a basal rosette
- Flowers actinomorphic, tetramerous (4 petals and sepals)
- Stamens tetradynamous (6 stamens; 4 long, 2 short)
