Educational worksheet for learning about plant types, featuring activities on angiosperms, gymnosperms, and non-flowering plants.

Here's the complete solution to all three tasks in your "UNIT 4. PLANTS" worksheet, with clear explanations.

## 1. Drag the words to the correct column.

We need to sort the terms into Angiosperms (flowering plants) and Gymnosperms (non-flowering seed plants).

✔ Angiosperms:

- apple tree → Produces flowers and fruit; classic example of angiosperm.
- rosebush → Also produces flowers and fruit (hips); angiosperm.
- produce fruit → Angiosperms are defined by having seeds enclosed in fruit.
- seeds develop in fruit → This is the defining feature of angiosperms.

✔ Gymnosperms:

- evergreen trees → Many gymnosperms (like pines, firs, spruces) are evergreen.
- seeds develop in cones → Gymnosperms produce naked seeds in cones (not enclosed in fruit).
- do not produce fruit → True for gymnosperms — they have cones, not fruit.

> 📌 *Note: “Do not produce fruit” could technically apply to non-seed plants too, but in this context, since we’re comparing angiosperms vs. gymnosperms, it belongs with gymnosperms.*

## 2. Select the odd one out.

a) Which of these is not a characteristic of non-flowering plants?

Non-flowering plants include mosses, ferns, and gymnosperms. But note: gymnosperms DO reproduce with seeds, while mosses and ferns reproduce with spores.

Let’s evaluate:

- ☑️ produce fruit → ✘ NOT a characteristic. Non-flowering plants do NOT produce fruit.
- ☐ do not reproduce with seeds → Some don’t (mosses, ferns), but gymnosperms do — so this is partially true.
- ☐ reproduce with spores → True for mosses and ferns.
- ☐ moss and ferns are examples → True.

✔ Correct answer: produce fruit
→ Because *no* non-flowering plant produces fruit. Fruit is exclusive to angiosperms.

---

b) Which of these is not a characteristic of angiosperms?

Angiosperms = flowering plants → produce flowers, fruit, seeds inside fruit.

- ☑️ seeds develop inside cones → ✘ WRONG. That’s gymnosperms.
- ☐ produce flowers and fruit → TRUE.
- ☐ seeds develop inside the fruit → TRUE.
- ☐ examples include apple trees and roses → TRUE.

✔ Correct answer: seeds develop inside cones

---

c) Which of these is not a characteristic of gymnosperms?

Gymnosperms = conifers, cycads, etc. → no flowers, no fruit, seeds in cones, often evergreen.

- ☑️ produce fruit → ✘ NO. Gymnosperms do NOT produce fruit.
- ☐ do not produce fruit → TRUE.
- ☐ seeds develop inside cones → TRUE.
- ☐ most are evergreen trees → TRUE (though not all — e.g., ginkgo loses leaves).

✔ Correct answer: produce fruit

## 3. Decide if these words describe flowering plants or non-flowering plants.

| Term | Flowering Plants | Non-flowering Plants |
|------------------------|------------------|-----------------------|
| reproduce with seeds | ✔ | ✔ (gymnosperms) |
| ferns | | ✔ |
| angiosperms | ✔ | |
| reproduce with spores | | ✔ (mosses, ferns) |
| mosses | | ✔ |
| gymnosperms | | ✔ |

> 💡 Important note:
> - “Reproduce with seeds” applies to both flowering (angiosperms) and non-flowering (gymnosperms) plants.
> - But since the question asks you to choose one category per row, and “reproduce with seeds” is more commonly associated with seed plants (which include both), it’s often grouped under flowering plants in simplified curricula — but technically, it applies to both.

However, looking at the structure of the worksheet, it likely expects:

✔ reproduce with seeds → Flowering plants *(because angiosperms are the dominant seed plants taught at this level)*
✔ ferns → Non-flowering
✔ angiosperms → Flowering
✔ reproduce with spores → Non-flowering
✔ mosses → Non-flowering
✔ gymnosperms → Non-flowering *(even though they make seeds, they’re non-flowering)*

> 🧠 Clarification:
> - “Flowering plants” = angiosperms only.
> - “Non-flowering plants” = everything else: mosses, ferns, gymnosperms.
> So even though gymnosperms reproduce with seeds, they are still classified as non-flowering.

## ✔ FINAL ANSWERS SUMMARY:

---

1. Drag and Drop:

Angiosperms:
- apple tree
- rosebush
- produce fruit
- seeds develop in fruit

Gymnosperms:
- evergreen trees
- seeds develop in cones
- do not produce fruit

---

2. Odd One Out:

a) produce fruit
b) seeds develop inside cones
c) produce fruit

---

3. Flowering vs Non-flowering:

| Term | Flowering Plants | Non-flowering Plants |
|------------------------|------------------|-----------------------|
| reproduce with seeds | ✔ | |
| ferns | | ✔ |
| angiosperms | ✔ | |
| reproduce with spores | | ✔ |
| mosses | | ✔ |
| gymnosperms | | ✔ |

*(Note: If your teacher allows dual classification for “reproduce with seeds”, you may mark both — but based on typical elementary worksheets, it goes under Flowering Plants.)*
