Nutrition and reproduction in plants. worksheet - Free Printable

Let's solve this worksheet step by step.

Part 1: Match

We are given a list of plant parts and asked to categorize them as FEMALE, MALE, or left over (not directly involved in reproduction).

#### Given terms:
- STAMEN
- PISTILS
- FRUIT
- SEEDS
- OVULES
- POLLEN GRAINS

Now, let’s classify:

#### Which parts are FEMALE?
- PISTILS – This is the female reproductive part of the flower.
- OVULES – These are located inside the ovary of the pistil and develop into seeds after fertilization.
- FRUIT – The fruit develops from the ovary after fertilization and protects the seeds. It is considered a female structure because it comes from the ovary.

✔ So, FEMALE: PISTILS, OVULES, FRUIT

#### Which parts are MALE?
- STAMEN – The male reproductive organ that produces pollen.
- POLLEN GRAINS – Produced by the stamen; contain male gametes.

✔ So, MALE: STAMEN, POLLEN GRAINS

#### Which words are left over?
- SEEDS – Seeds are formed after fertilization but are not reproductive organs themselves. They are the result of reproduction.
- However, note that seeds come from ovules (female) and are not classified as male or female parts.
- But since they’re not reproductive structures *per se*, they may be "left over" in this context.

So, LEFT OVER: SEEDS

> ✔ Final Answers:
> - FEMALE: PISTILS, OVULES, FRUIT
> - MALE: STAMEN, POLLEN GRAINS
> - LEFT OVER: SEEDS

Part 2: Choose the correct word

We have a diagram of a flower with labeled parts. We need to label each part using the words from earlier.

From the diagram:
- The top part with anthers and filaments → STAMEN
- The central structure with stigma, style, and ovary → PISTILS
- The oval structure at the bottom of the ovary → OVULES
- The small circle outside the flower → likely represents POLLEN GRAINS (as it's shown being released)

But looking closely at the arrows:

1. Arrow pointing to top yellow parts → STAMEN
2. Arrow pointing to central structure → PISTILS
3. Arrow pointing to oval inside ovary → OVULES
4. Arrow pointing to small round object near flower → POLLEN GRAINS

✔ So fill in:
- Top right arrow → STAMEN
- Bottom right arrow → OVULES
- Left middle arrow → PISTILS
- Left bottom arrow → POLLEN GRAINS

> Wait — actually, the diagram has:
> - One arrow pointing to the anther/filament → STAMEN
> - One to the central column → PISTILS
> - One to the ovule → OVULES
> - One to the pollen grain (outside) → POLLEN GRAINS

So the labels should be:
- Right top → STAMEN
- Right bottom → OVULES
- Left top → PISTILS
- Left bottom → POLLEN GRAINS

✔ Final labeling:
- Top right box → STAMEN
- Bottom right box → OVULES
- Top left box → PISTILS
- Bottom left box → POLLEN GRAINS

Part 3: Complete with correct word

This section is about photosynthesis.

Given formula:
> Photosynthesis = minerals + water + sunlight + carbon dioxide = food + oxygen

Now, complete the sentences:

1. Roots absorb water from the soil.
→ Already filled: water

2. Roots absorb [ ] from the soil.
→ Roots absorb minerals from the soil.
✔ Fill: minerals

3. The leaf absorbs carbon dioxide from the air.
→ Already filled.

4. The leaf absorbs [ ]
→ The leaf absorbs sunlight (from the sun).
✔ Fill: sunlight

5. [ ] and minerals pass through the stem to the leaves.
→ Water and minerals move up the stem via xylem.
✔ Fill: water

6. When plants make food they make [ ] too and return it to the air.
→ Plants produce oxygen during photosynthesis.
✔ Fill: oxygen

✔ Final Answers:

#### Match:
- FEMALE: PISTILS, OVULES, FRUIT
- MALE: STAMEN, POLLEN GRAINS
- LEFT OVER: SEEDS

#### Choose the correct word (diagram):
- Top right → STAMEN
- Bottom right → OVULES
- Top left → PISTILS
- Bottom left → POLLEN GRAINS

#### Complete with correct word:
1. Roots absorb water from the soil. → water
2. Roots absorb minerals from the soil.
3. The leaf absorbs carbon dioxide from the air. → already complete
4. The leaf absorbs sunlight
5. Water and minerals pass through the stem to the leaves.
6. When plants make food they make oxygen too...
