Here's the completed worksheet with explanations for each answer:
---
Choose angiosperms or gymnosperms.
1.
Gymnosperms don’t have flowers.
→ *Explanation:* Gymnosperms are “naked-seeded” plants that do not produce flowers or fruits. Their seeds are exposed, often on cones.
2.
Angiosperms have flowers that produce fruit.
→ *Explanation:* Angiosperms are flowering plants. After pollination, their flowers develop into fruits that enclose the seeds.
3.
Gymnosperms produce cones with seeds inside.
→ *Explanation:* Although gymnosperm seeds are “naked,” they are typically borne in cones (like pinecones), which protect and disperse them.
4. Conifers, like the pine tree, are
gymnosperms.
→ *Explanation:* Conifers (e.g., pines, spruces, firs) are a major group of gymnosperms. They reproduce via cones, not flowers.
5.
Angiosperms can be trees, grasses or bushes.
→ *Explanation:* Angiosperms include an enormous diversity of plant forms — from towering trees (oaks, maples) to grasses (wheat, rice) to shrubs (roses, azaleas).
6.
Gymnosperms can be bushes or trees.
→ *Explanation:* Most gymnosperms are woody plants — trees like pines and cedars, or shrubs like junipers. They rarely grow as herbaceous plants (like grasses).
7. A pear tree is an
angiosperm.
→ *Explanation:* Pear trees produce flowers that become pears (fruits). Since it has flowers and produces fruit, it’s classified as an angiosperm.

Image Matching:
-
Top left image (apple tree with fruit) →
Angiosperm
→ Apples are fruits produced by flowering trees — classic angiosperms.
-
Top right image (evergreen conifer tree) →
Gymnosperm
→ This looks like a cedar or pine — typical coniferous gymnosperm.
-
Bottom left image (pine needles + pinecones) →
Gymnosperm
→ Pinecones are the reproductive structures of gymnosperms.
-
Bottom right image (field of red poppies) →
Angiosperm
→ Poppies are flowering plants; they produce showy flowers and eventually seed pods (fruit).
