Bio 101

plants

store energy as carbohydrate, make their own food, have cell walls made of
cellulose and their cells have a nucleus and organelles

all plants need

sunlight, minerals, water and nitrogen to survive

Soil is formed by

weathering and biological activity and therefore may contain
weathered rock and decaying organic matter. Lichens produce acids that release minerals From rock and bacteria add nitrogen from the atmosphere to the soil

The following is a sequences in ecological succession

Lichens, mosses, herbs, shrubs, pine trees, and broad leaf trees

Plants compete for

sunlight, space, minerals and water

The following sequence is in the correct order of the evolution of the plants;

green algae, nonvascular plants, vascular plants, seed bearing plants, and flowering plants

Regarding Plants

Liverworts are flat nonvascular plants that are dependent on moist environments.
Mosses are erect nonvascular plants that are dependent on moist environments.
Ferns are primitive vascular plants that are dependent on moist environments.
Conifers are vascular plants that live in terrestrial environments and depend on wind for
fertilization.
Flowering plants are vascular plants that live in terrestrial environments and depend on
animals for fertilization

Early plants

did not have vascular tissue, had limited growth in height, had shallow
roots because their habitats did not have well developed soil, and were dependent on
water in the environment for fertilization
