What do we call a type of tree that produces seed bearing cones?
Conifers are trees that produce cones to protect their seeds. The cones have many scales to shelter the seeds.
What is a biome quizlet 4 3?
Biome. A graphical region that contains plants and animals for that regions.
What is a forest that contains trees that shed their leaves during a specific season?
deciduous forest, vegetation composed primarily of broad-leaved trees that shed all their leaves during one season.
Which tree has needle shaped leaves with waxy coating?
Coniferous trees have small, waxy and usually narrow leaves (needles or flat scales). 'Coniferous' means that it is a cone-bearing tree. The most common conifers are spruces, pines and firs. Alternative names used for coniferous trees are evergreens, softwoods and (appropriately enough) conifers.
Which plants have needle shaped leaves?
Pines, spruces, firs and cedars are some trees with needle shaped leaves. The leaves have needle shape because of dryness in air to prevent the water loss due to transpiration.
What are two differences between cones and fruits?
The difference between cone-bearing plants and fruit-bearing plants is that cone-bearing plants, called gymnosperms, develop a seed that is part of a cone structure. A gymnosperm seed is not protected inside a fruit, as is the case with fruit-bearing plants that came later.
Which of the following trees develop cones?
Conifers are cone-bearing seed plants which develop their seeds inside cones.
What tree drops pine cones?
Pine (Pinus) trees are known for the large cones they produce which are commonly used in craft projects. These cones appear on both male and female pine trees and shrubs. The shore pine (Pinus contorta) is a needled evergreen tree best grown in coastal areas in USDA zones 6 through 8.
What is another name for tropical savannas?

What is used to classify biomes?
A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.
What kinds of trees do temperate forests contain?
Most temperate forests are made up of a mix of deciduous trees like oak, beech, maple, ash, hazel, and birch, along with some evergreens and conifers like pine, redwood, hemlock, and cedar.
What area of the forest that is formed by the leaves of tall trees?
The leafy tops of tall trees-extending from 50-80 meters above the forest floor- form a dense covering called the canopy. In the shade below the canopy, a second layer of shorter trees and vines forms an understory.
Why trees shed their leaves?
The main reason for leaf drop on most trees is that, come winter, it gets pretty cold and dry in our part of the world. Rather than expend energy to protect these fragile organs, trees shed leaves to conserve resources.
Why plants shed their leaves in winter?
Winter temperatures cause the production of auxin to slow down and this breaks the abscission layer, causing the leaves to detach from the trees. Losing leaves helps the tree to retain water during in the winter and means that it needs less energy to stay alive. The fallen leaves help to add nutrients to the soil.
