Yes.
By the way, if you're going to use answers.com to cheat on a test at least paraphrase the question or something, copy-pasting the question and just taking out the blank between "developed" and "?" is simply lazy. Seriously, would it kill you to add "what" before the question mark?
There are estimated to be around 300,000 species of angiosperms (flowering plants) in the world today. They make up the majority of all plant species on Earth.
Angiosperms They produced seeds that are protected they are the most diverse and abundant land plants today. Present day angiosperms that evolved during the mesozic era include magnolia and oak trees.
When the Earth first formed, there was an abundant amount of deuterium in the atmosphere. Today, most of the deuterium has fused into helium and because of that, there is little deuterium left.
Seed plants today belong to the division Spermatophyta, which includes gymnosperms (e.g. conifers, cycads, ginkgo) and angiosperms (flowering plants). Angiosperms are the most diverse group and comprise the majority of seed plants found today.
Plant life on Earth likely began around 700 million years ago with the evolution of simple photosynthetic organisms, such as algae. These early plants gradually evolved into more complex forms, eventually diversifying into the wide variety of plant life we see today. The process of photosynthesis, where plants convert sunlight into energy, played a crucial role in the development and sustenance of plant life on Earth.

Precambrian
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.
Oxygen
Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of the total volume. Oxygen is the second most abundant gas, at around 21%.
shrubs ferns
Coal-forming swamps covered the Earth during the Carboniferous period, approximately 360 to 300 million years ago. This period is known for abundant plant growth, particularly lycopods and tree ferns, which accumulated and were transformed into the coal deposits we see today.

Nitrogen (N2) is the most abundant molecule in Earth's atmosphere, making up about 78% of the gases present. Oxygen comes in second, at around 21%.
