tropisms
Tony wanted to see if he could make the roots of a plant grow up instead of down. After several tries, he found that the roots always grew down. Nothing he or his teacher did made the roots grow up. What keeps the roots from growing up?
geotropism/gravitropism
Which part of a tree always grows down because of gravity?
roots
Identify which part of the flower is responsible for making pollen?
anther
What part of the plant contains tubes that absorb water from the soil?
roots
The place in plants where photosynthesis, respiration, and transpiration occur
leaves
Mr. Walker plants a new plant next to a tall tree in his yard. It is partly in the sun, but is mostly in the shade. He notices that it is growing with all of its leaves on one side. Why is the plant growing this way?
phototropism
What part of the flower is used for transporting water?
Identify which part of the flower that is sticky and collects pollen grains off of pollinators ?
stigma
Name the tubes that carry water and the tubes that carry food in a vascular plant.
xylem and phloem
guard cells
the response to any external stimuli
tropisms
cell to cell
Many flowering plants have very colorful petals like the lily seen here. What is the main purpose of these colorful petals?
attract insects
Roots with several main branches off that form a root mass are called ___________. Grass, corn and some trees are examples.
fibrous roots
when water is released from the leaves
transpiration
This plant needs to grow high up in the canopy of the rainforest. It needs support as it moves up the stems and branches of larger trees. The tendrils here know when to cling to their support. This response by the climbing plant is called
thigmotropism
This tree is found in hot, tropical areas where there are many large, grazing animals. What is one positive reason why this tree has developed thorns on the bark?
protects from animals
The bee is pollinating the flower. This is an important step in the ____________ of flowering plants.
sexual reproduction
Tabatha and Debbie are writing observations in their notebook about plants. They write in their notebook "plant is green, short, has no stem and no roots." What did they describe?
nonvascular
respiration
Seasonal changes bring about scenes like this one. Plant cells respond to changes in _________________ and as a result, photosynthesis slows and leaves change color.
light intensity and temperature
Apples and other fruit fall from trees and are eaten by animals. What advantage does fruit provide for the seeds inside?
protects the seeds from predators
Describe the process of pollination. Use the terms: anther, stigma, style, ovary.
The pollen from the anther is carried to another flowers stigma, where the pollen grows down the style and then meets the ovules inside the ovary.
Give me 2 examples of nonvascular plants.
Roots with one main root are called ___________. Carrots are examples.
tap roots
