Plant Structures For Growth
Plant structure responsible for water and nutrient absorption.
Roots
two systems involved when a frog is startled and jumps to avoid danger
nervous, muscular
This structure produces pollen and holds seeds- for gymnosperms and angiosperms
Cones/ Flower
Process of removing nitrogen from the air using bacteria
Nitrogen fixation
What are the two parts of the plants vascular system that is responsible for growth and water/nutrients transportation?
Xylem & Phloem
Type of feedback that brings the body back to its original state such as sweating when too hot.
Negative feedback system
The type of species isolation based on mating rituals.
Behavioral isolation
Which mechanisms of evolution involves random changes in DNA sequences?
Mutations
What sort of things are moved through the circulatory system?
Blood, nutrients, and waste
What is the difference between a petal and a sepal?
Petals protect the pistil and attract pollinators and sepals protect the blossoming bud.
What are the 5 evidences of evolution?
Fossil record, embryology, DNA, biogeography, anatomical structures
These structures play a role in the circulatory system in animals as well as photosynthesis in plants.
Lungs for animals, stomata for plants
The preference of female elk choosing male elks with larger antlers
Sexual selection
What is Biodiversity?
The amount of different species in an ecosystem
Plant growth that is a result of touch
Thigmotropism
Traits that allow organisms to continue to survive and thrive
adaptations
The female and male reproductive parts of a flower and what they consist of
Pistil- female- style, ovule, stigma, ovary
stamen- male- anther and filament
Competition within the same species
intraspecific competition
