Plant Worksheet A. Vascular Plant B. Nonvascular Plant C. Xylem D ... - Free Printable

Here are the correct answers for your Plant Worksheet, with a quick explanation for each to help you understand why.

Part 1: Vocabulary Matching

1. c (xylem)
* *Reasoning:* Xylem is the "water pipe" of the plant. It carries water and minerals up from the roots.
2. d (phloem)
* *Reasoning:* Phloem is the "food pipe." It carries the sugar (food) made in the leaves down to the rest of the plant.
3. a (vascular plant)
* *Reasoning:* Vascular plants have tubes (xylem and phloem) that act like a skeleton, allowing them to grow tall.
4. e (photosynthesis)
* *Reasoning:* This is the scientific name for the process where plants use sunlight to make their own food.
5. b (nonvascular plant)
* *Reasoning:* Mosses and liverworts don't have tubes for water, so they stay small and close to the ground.
6. f (spores)
* *Reasoning:* Plants like ferns and mosses don't make seeds; they release tiny dust-like particles called spores to reproduce.
7. h (monocot)
* *Reasoning:* "Mono" means one. Monocots (like corn or grass) have seeds with just one part inside (one cotyledon).
8. g (dicot)
* *Reasoning:* "Di" means two. Dicots (like beans or peanuts) have seeds that split into two halves.

Part 2: Multiple Choice

9. c (helping support the plant)
* *Reasoning:* Besides carrying water, the stiff walls of xylem cells act like wood to hold the plant up.
10. a (Monocot Plants)
* *Reasoning:* If you look at a blade of grass or a lily leaf, the lines (veins) run straight up and down parallel to each other.
11. b (Dicot Plants)
* *Reasoning:* Flowers with petals in groups of 4 or 5 (like roses or buttercups) are usually dicots.
12. c (They both respond to their environment)
* *Reasoning:* Just like animals move away from danger, plants turn toward light or close their leaves when touched.
13. d (Moss)
* *Reasoning:* Moss has no internal tubes for water, making it nonvascular. Ferns, monocots, and dicots all have tubes.
14. b (Seed)
* *Reasoning:* The ovary protects the baby plant. When it matures, the ovary becomes the fruit/seed container.
15. b (Cones)
* *Reasoning:* Pine trees and evergreens are "cone-bearing" plants (conifers). They do not have flowers.
16. a (Amount of light)
* *Reasoning:* Seeds travel by wind, water, or sticking to animals. Light helps them grow *after* they land, but it doesn't move them.
17. c (Nonvascular)
* *Reasoning:* Because they lack pipes (vascular tissue), these plants must absorb water directly through their skin from the air or soil.
18. a (Spores)
* *Reasoning:* "Flowerless" usually refers to ferns and mosses, which reproduce using spores instead of seeds.
19. a (Vascular)
* *Reasoning:* To grow large and tall, a plant needs a strong internal structure (vascular tissue) to hold it up and feed it.
20. a (Corn)
* *Reasoning:* Corn is a flowering plant that produces kernels, which are seeds. Mosses and ferns use spores, and mushrooms are fungi.
