Tropisms
What is phototropism?
A plants response to light
What is the function of Xylem Tubes?
To transport water and minerals
What is Turgor Pressure?
The pressure water-filled vacuoles place on the cell membrane to keep the plant rigid
What is the function of the digestive system?
To break down food for nutrients and energy
What is the function of mitochondria?
To create and release energy
What is a plants response to gravity?
Geotropism
Which plant structure absorbs sunlight?
leaves
What is Emergence of a Seedling?
The force the plant places on the seed during germination. The roots grow down and the stem/leaves grow up
Which system in a plant is below ground and provides the stem/leaves with water and minerals?
Root System
Explain homeostasis
The body creating balance
What type of tropism is used when a vine grows up a wall?
Thigmotropism
What part of a flower contains the female reproductive organs?
Pistil
What is the process of water moving in and out of the plant called?
Osmosis
Which plant system consists of the stem, leaves and flowers
Draw an animal cell and a plant cell
animal cell = round
plant cell = square
Name all four pre-fixes of tropism and explain what each one means?
Hydro = Water
Thigmo = Touch
Geo = Gravity
Photo = Light
What is the Stamen?
The male reproductive parts of a plant
Explain why it is important for veins to have valves?
To transport blood against the force of gravity
Which body system is responsible for oxygenating blood?
Respiratory System
What is a response the human body has to be infected by bacteria or other pathogens?
Explain a positive and negative response to gravity.
Positive = roots grow down
Negative = stem/leaves grow up
Which plant structure is responsible for transporting food (sugar) throughout the plant?
Phloem
What does it mean for a plant cell to be hypertonic?
The vacuole is not filled with water
Which body system is responsible for isolating waste?
Excretory System
