Watch the video and answer the questions.

Compare and contrast the seeds in the pine cone and in the apple.

Thinking about the structures of both of the types of seeds, infer how both of the plants might reproduce.

The seeds look similar,

but the seeds in the pinecone have a “tail.” The seeds in the

apple are inside the fruit, but the pinecone seeds can leave

the pinecone

I think the seeds fall out

of the pinecone and travel by wind, but the seeds of the

apple must be eaten by an animal and released in the

animal’s waste or released when the apple rots.

Reproduction in plants

Types of Plant Reproduction

Some plants reproduce sexually, some plants reproduce asexually, and some plants can reproduce in both ways.

Asexual reproduction occurs when a portion of a plant develops into a separate new plant.

Sexual reproduction occurs when a plant’s male reproductive cell (sperm) combines with a plant’s female reproductive cell (egg). The way a plant reproduces depends on the structures it has.

Not all plants grow from seeds.

Plants that do not produce seeds are called seedless plants.

The first land plants to inhabit Earth most likely were seedless plants

They produce either by asexual reproduction or by producing spores.

Mosses and ferns are examples of seedless plants found on Earth today.
