Influences of Plant Growth
Name two internal factor that influences Growth
Genetics & Hormones
Plants Response to Touch
Thigmotropism
A plants response to SEASONAL CHANGE
Photoperiodism (light+time)
Name 3 positive environment conditions that are necessary help a plant grow
sunlight, water, nutrient rich soil
The organ/sack that surrounds the baby/embryo and transfer the essential nutrients needed provided by mom
The placenta
An important Hormone that affects plant growth and development, specifically the rate at which a plant grows and responds to light
Auxin
Plants Response to Light
Phototropism
Period of time when an organism stops activity or growth
Dormancy
Name some negative environmental conditions that can impact plants.
Diseases, pests, overly crowded areas with poor soil, and little soil (competition of space)
This connects mother and baby via belly button
the umbilical cord
What is the process called of a plant growing towards or away from stimulus
Tropisms
Plants response to Gravity
Gravitropism
True or False: ALL PLANTS are affected by seasonal change
False
After fertilization the embryo may develop _______ or _______ the female's body.
Inside or outside
The process of body changes as they grow and develop into adults is ________________.
metamorphosis (ex: crayfish, crabs, frogs)
Name 3 stimuli that trigger a plants response....
Touch, Light & Gravity
Follows Gravity: roots growing downward
Positive Gravitropism
What is the first visible change of process of dormancy
Leaves Color Change
Name some examples of placental animals.
Human, dogs, cats, cows, elephants, horses.
Internal factors that affect animal growth are:
Genetic and Hormonal
Outside Factors that affect plants growth
The conditions of environment, response to stimuli and resources
Does not follow gravity: stem growing up
Negative Gravitropism
The breakdown of this __________ causes yellow/orange leaf color.
Chlorophyll
Placental Animals embryos develop...
inside mother until development is complete and the embryo can survive on its own.
External factors that affect animal growth and development
Parasites, disease, and space
