What does fertilization not require in most seed plants?
Fertilization in most seed plants does not require swimming sperm, as they are transported within pollen grains and delivered directly to the plant ovule for fertilization to occur. This eliminates the need for water as a medium for fertilization, unlike in non-seed plants or aquatic plants where swimming sperm are necessary to reach the egg.
What division do most seed plants belong to today?
Most seed plants belong to the division Magnoliophyta, also known as flowering plants. They are the most diverse group of plants on Earth, with over 300,000 species. Magnoliophyta includes trees, shrubs, herbs, and many food crops.
Are Flowering plants are the most common type of seed-bearing plants.?
Yes, that is correct. Flowering plants, also known as angiosperms, are the most numerous group of seed-producing plants on Earth. They are characterized by the presence of flowers, which are reproductive structures that produce seeds enclosed within a fruit.
Is a chili is a dicot?
No, chili plants are classified as dicotyledonous plants, meaning they have two cotyledons in their seed. This is a common characteristic of most flowering plants.
Do all plants produce seed?
Not all plants do actually. Most Vascular Plants ( plants with tubes ) have seeds. Some plants have spores instead of seeds.
What does fertilization not require in most seed plants?

This eliminates the need for water as a medium for fertilization, unlike in non-seed plants or aquatic plants where swimming sperm are necessary to reach the egg.
What plants can produce seeds?
The seed produces another generation of that plant after germination.
Do gametophytes of seed plants are very large?
No, gametophytes of seed plants are usually very small and dependent on the sporophyte for nutrients. They are reduced in size compared to the sporophyte generation.
What life cycle components appear only in mosses and ferns?
The gametophyte generation is more prominent and independent in mosses and ferns compared to seed plants. Also, the sporophyte generation in mosses and ferns is not as prominent or long-lived as in seed plants. Finally, mosses and ferns rely on water for fertilization, a characteristic not seen in seed plants.
From what do most plants grow?
seed
Is sporophyte dominant in seed plants?
Yes, sporophytes are the dominant generation in seed plants. In these plants, the sporophyte is the larger, more complex structure that carries out photosynthesis and is responsible for reproduction. The gametophyte generation is reduced and often dependent on the sporophyte for nutrients and protection. This shift to a dominant sporophyte is a key characteristic of seed plants, distinguishing them from other plant groups like mosses, where the gametophyte is more prominent.
What do most flowering plants grow from?
seed
Did non-seed plants evolve from seed plants?
Non-seed plants evolved from seed plants.
How did Mendel show that the green-seed trait did not disappear but was only masked?
Mendel demonstrated that the green-seed trait did not disappear but was simply masked by conducting crossbreeding experiments with pea plants. He observed that when he crossed purebred yellow-seed plants with purebred green-seed plants, the first generation (F1) exhibited only yellow seeds. However, when he allowed the F1 generation to self-pollinate, the second generation (F2) revealed a 3:1 ratio of yellow to green seeds, indicating that the green-seed trait was still present but hidden in the F1 generation. This suggested the concept of dominance, where the yellow trait masked the expression of the green trait.
What is the product of offspring?
The offspring of plants are seedlings that grow and then become plants, then they reproduce and the cycle goes on and on.
The most ancient surviving seed plants are the?
Mosses
