Plant Systems & Homeostasis

What is turgor pressure?

Back

Turgor pressure is the pressure exerted by water inside a plant cell pushing against the cell wall, which helps maintain the plant's structure.

Front

What happens to a plant without turgor pressure?

Back

Without turgor pressure, a plant wilts and loses its rigidity, leading to drooping leaves and stems.

Front

What are tropisms in plants?

Back

Tropisms are responses in plants that result in movement toward or away from a stimulus, such as light or gravity.

Front

What is the role of gravity in plant growth?

Back

Gravity influences the direction of growth in plants, causing roots to grow downward and stems to grow upward.

Front

How does water affect seed germination?

Back

Water within the seed creates turgor pressure that pushes against the seed coat, helping to split it open for the seedling to emerge.

Front

What is the effect of gravity on plant roots?

Back

Gravity causes plant roots to grow downward, a response known as positive gravitropism.

Front

What is the effect of gravity on plant stems?

Back

Gravity causes plant stems to grow upward, a response known as negative gravitropism.

Front

What is the main stimulus that scientists study in space regarding plant growth?

Back

Scientists study the effects of gravity on plant growth in space.

Front

What is differentiation in plants?

Back

Differentiation is the process by which plant cells develop into different types of cells with specific functions.

Front

What are adaptations in plants?

Back

Adaptations are characteristics that enhance a plant's ability to survive and reproduce in its environment.
