Why do plants develop tropisms (which help them maintain homeostasis and stay alive)?
Plants need food and water to live. They grow towards sources of food in the soil in order to eat.
Plants depend on people to keep them alive and well. Tropisms are designed to help people understand why plants only respond when people water them and keep them in the sunlight.
Plants need light and water for photosynthesis. They have developed responses called tropisms to help make sure they grow towards sources of light and water.
Tropisms are not important for plant growth and homeostasis. The correct answer is not shown here.

Regulate cell division and growth
Which organelle is responsible for maintaining turgor pressure in plant cells?
mitochondria

What is the role of vacuoles in turgor pressure?
Vacuoles store air instead of water to create turgor pressure.
Vacuoles store water and other substances to create osmotic pressure for maintaining turgor pressure.
Vacuoles have no role in maintaining turgor pressure.
Vacuoles release water to decrease osmotic pressure and reduce turgor pressure.
Name one factor that can affect turgor pressure in plant cells.

How does water uptake affect turgor pressure?
Decreases
Has no effect
Fluctuates
