First land plants: Where must they live?
Seedless nonvascular plants are the first land plants and must live in wet areas.
How do seedless nonascular plants transport water?
They move water only a few centimeters through osmosis.
How do seedless nonvascular plants reproduce?
They reproduce with spores made inside capsules.
What is a seedless nonvascular plants significance in fossil fuel formation?
Their fossils became fossil fuels.
Give examples of seedless nonvascular plants
Examples include moss and liverworts.
What are seedless vascular plants known for?
First forests xylem root stem phloem leaves
What are the defining features of flowering plants
Vascular tissues and organs Flowers and fruits Stamen Carpel Fruit Pollination diversity
Describe the role of plants in food webs.
Plants are primary producers, providing the primary source of carbohydrates.
Explain the role of plants in nutrient cycles.
Trees and other plants take up mineral and non-mineral nutrients from the soil through their roots
Photosynthesis
Photosynthesis involves the cycling of carbon, oxygen, nitrogen, and water
Decomposition
Decomposition by plants returns nutrients to the community.
What types of symbiosis do plants engage in
Plants engage in all types of symbiosis, including mutualism, commensalism, and parasitism.
What are the roles of plants in fuel production?
Plants are used to produce various fuels, including biofuels.
How are plants important for medicine and other products?
Plants are used to produce a wide range of medicines and products, contributing significantly to healthcare and industry.
