It's impossible to list all plants with seeds and how many they have. There are hundreds of thousands of plant species, each with varying seed numbers. However, I can explain how seeds work and give you some examples of seed numbers:

What are Seeds?

Seeds are essentially tiny packages containing a plant embryo, food reserves (endosperm), and a protective coat. They are the result of sexual reproduction in flowering plants (angiosperms) and cone-bearing plants (gymnosperms).

Seed Number Variation:

The number of seeds a plant produces varies greatly depending on:

* Plant Species: Some plants, like orchids, produce only a few seeds, while others like sunflowers produce thousands.

* Environmental Conditions: Factors like sunlight, water, and nutrients affect seed production.

* Pollination Success: The effectiveness of pollination influences how many seeds are fertilized and develop.

Examples of Seed Numbers:

* Apple: One apple typically has 5-10 seeds.

* Sunflower: A single sunflower can produce thousands of seeds.

* Oak Tree: An oak tree can produce hundreds of acorns (seeds) each year.

* Corn: Each ear of corn can have hundreds of kernels (seeds).

How to Find Seed Numbers:

If you are curious about the seed number of a specific plant, you can:

* Consult plant guides or online databases: Many resources provide information on plant characteristics, including seed production.

* Observe the plant directly: Count the seeds in a fruit, pod, or seed head.

Remember, seed number is just one aspect of plant reproduction. Understanding the factors that influence seed production can be fascinating!
