Unit 1 - Life cycle of a flowering plant worksheet - Free Printable

I will solve the problems presented in the image, which are Q7 (seed dispersal) and Q8 (flower parts labeling). I'll tackle them one at a time, starting with Q7.

Solving Q7: Seed Dispersal

First, look closely:
The question asks to match each method of seed dispersal with the correct fruit from the provided illustrations. The methods listed are:
- Wind
- Animal: eaten
- Animals: fur
- Explosion
- Drop and roll
- Water

The fruits shown are: maple, grapefruit, cleaver, kei apple, strawberry, water lily, dandelion, and geranium.

I need to identify which fruit corresponds to each dispersal method based on biological knowledge.

Next, find information:
I will use my knowledge of botany to match each fruit to its dispersal method.

- Wind: Dandelion seeds have a parachute-like structure that allows them to be carried by the wind. Maple seeds also have wings for wind dispersal.
- Animal: eaten: Fruits like strawberries and grapefruits are often eaten by animals, and the seeds are dispersed through their droppings.
- Animals: fur: Cleavers (also known as goosegrass) have sticky burrs that attach to animal fur.
- Explosion: Geraniums can have seed pods that burst open when ripe, scattering seeds.
- Drop and roll: Kei apples are round and can roll away from the parent plant after falling.
- Water: Water lilies grow in water, and their seeds are dispersed by water currents.

Then, review the findings:
Based on this analysis, I can fill in the table as follows:

| Method of seed dispersal | Fruit |
|--------------------------|--------------|
| Wind | dandelion |
| Animal: eaten | strawberry |
| Animals: fur | cleaver |
| Explosion | geranium |
| Drop and roll | kei apple |
| Water | water lily |

Note: While maple is also dispersed by wind, dandelion is more iconic for wind dispersal due to its parachute structure. Similarly, grapefruit could also be under "Animal: eaten," but strawberry is more commonly associated with this method in educational contexts.

Solving Q8: Flower Parts Labeling

First, look closely:
The question asks to label the parts of the flower shown in the diagram. The labels A through H point to different parts of the flower.

I need to identify each part based on standard flower anatomy.

Next, find information:
I will use my knowledge of flower anatomy to identify each labeled part.

- A: Points to the stigma, which is the receptive tip of the pistil.
- B: Points to the style, which is the tube connecting the stigma to the ovary.
- C: Points to the ovary, which contains the ovules.
- D: Points to the sepal, which is part of the calyx and protects the flower bud.
- E: Points to the anther, which produces pollen.
- F: Points to the filament, which supports the anther.
- G: Points to the petal, which attracts pollinators.
- H: Points to the receptacle, which is the base of the flower where all parts are attached.

Then, review the findings:
Based on this analysis, I can fill in the labels as follows:

- A: Stigma
- B: Style
- C: Ovary
- D: Sepal
- E: Anther
- F: Filament
- G: Petal
- H: Receptacle
