What were the first plants that did not require water for transferin sperm to eggs?
The first plants that evolved to not require water for transferring sperm to eggs were the gymnosperms, such as conifers and cycads. Gymnosperms produce seeds that are not enclosed in a fruit, allowing them to be dispersed without the need for water for reproduction. This adaptation allowed them to colonize drier environments and diversify during the Paleozoic era.
After the amniotic egg evolved what was a result?
The amniotic egg allowed animals to reproduce on land, leading to the diversification of terrestrial vertebrates. This adaptation provided embryos with protection against desiccation and allowed for the colonization of diverse habitats.
What did a vascular system do for plants size-wise?
The development of a vascular system in plants, which includes xylem and phloem, allowed them to efficiently transport water, nutrients, and sugars throughout their structures. This adaptation supported larger plant sizes by enabling greater structural support and height, facilitating access to sunlight and resources. As a result, vascular plants could dominate terrestrial ecosystems, leading to increased diversity and complexity in plant forms. Overall, the vascular system was crucial for the evolutionary success of larger and more complex plants.
What is a climate change that allowed flowering plants to increase?
The climate change that allowed flowering plants to increase was the gradual cooling of Earth during the Cretaceous period, which created more temperate climates. This change provided favorable conditions for the diversification and spread of flowering plants, enabling them to outcompete other plant species and dominate terrestrial ecosystems.
What adaptation allowed plants to live successfully on land?
The development of a cuticle, stomata, and roots allowed plants to live successfully on land. The cuticle prevents water loss, stomata regulate gas exchange, and roots provide anchorage and access to water and nutrients from the soil.
Which adaptation allowed gymnosperm plants to out-compete spore-bearing plants?
The evolution of seeds in gymnosperms allowed them to out-compete spore-bearing plants by providing a protective and nutrient-rich environment for the embryo to develop. Seeds also have adaptations for dispersal, enabling gymnosperms to colonize diverse habitats and spread more efficiently than spores.
Why are seeds an important structure adaptation?
The development of seeds allowed plants to spread widely and colonize the land. Seeds could be carried in animals' intestines or blown by the wind to create offspring far from the original plant.
Why was Francisco Pizarro important?
Because it allowed Spain to colonize modern day Peru.
What was the most significant evolutionary change that allowed reptiles to colonize all the land was the evolution of?
Amniote egg
What advantage allowed both reptiles and gymnosperms to dominate as life forms in the mesozoic?
i like turtles
What allowed mammals to spread and dominate duringr this era?
Natural selection and really good traits.
Why was the evolution of spores important to the success of life on land?
Spores allowed plants to reproduce and disperse in a dry environment, enabling them to colonize land. Spores served as a protective mechanism against desiccation and helped plants survive in diverse habitats. This adaptation was essential for the transition of plants from aquatic to terrestrial environments.
What was the significance of Francisco Pizarro 's exploration?
Because it allowed Spain to colonize modern day Peru.
Why did Europe dominate the world economy by the beginning of the twentieth century?
Europe had enormous capital and industries which allowed it to dominate the world economy by the beginning of the twentieth century. It was also superior militarily.

What statement best describes the message of the Monroe Doctrine?
Americans would resist European interventionEuropean countries could not colonize South America.Europe was no longer allowed to colonize the Americas.Europe could no longer colonize the americas.
