What is the role of chlorophyll in palisade cells?

To absorb sunlight for photosynthesis

Which feature of root hair cells allows them to efficiently absorb water?

They have a long, thin extension.

They have a large central vacuole.

Why do root hair cells not contain chloroplasts?

Root hair cells are found in parts of the plant that are underground, where there is no sunlight.

Root hair cells do not need energy for their function.

Root hair cells get their energy directly from the soil.

Root hair cells are too small to hold chloroplasts.

What is the correct order of parts that water moves through in a root hair cell, from the soil to the sap vacuole?

Soil → Cell wall → Cell membrane → Cytoplasm → Sap vacuole

Cell membrane → Cytoplasm → Sap vacuole

Soil → Root hair → Cell wall → Cell membrane → Cytoplasm → Sap vacuole

Soil → Root hair → Cytoplasm → Cell membrane → Cell wall → Sap vacuole

What is the definition of a tissue?

A group of similar cells working together

A group of different types of cells

A single cell performing a specific function

What is the main function of ciliated epithelium in animals?

To move mucus and trapped particles out of the lungs

Which characteristic is common to both onion epithelium and ciliated epithelium?

Both types of tissue have specialized cells with unique functions.

Both types of tissue are responsible for photosynthesis.

Both types of tissue provide structural support.

Both types of tissue are found only in plants.

What is a key feature of ciliated epithelium that distinguishes it from other types of tissues?

It contains cilia that move in unison.

It has a thick, protective layer.

It is composed of only one type of cell.

It is found only in the roots of plants.

Which statement about organs and organ systems is correct?

An organ system consists of different organs that work together to carry out a specific function.

Organs are composed of a single type of cell that performs a specific function.

Plants do not have organs, only tissues and cells.

All organs in an organism perform the same function.

What is a characteristic of liquids?

Liquids take the shape of their container but maintain the same volume.

Liquids keep a fixed shape and volume.

Liquids can be compressed and poured.

Liquids cannot change shape or volume.

What is the arrangement of particles in a solid?

Particles are arranged in a fixed pattern and tightly packed

Particles are randomly scattered

Particles are loosely held together

Particles are far apart and moving freely

What happens to the particles in a solid when it is heated?

They vibrate more and take up more space

They move freely in all directions

They get smaller and closer together

What happens when a solid melts?

The particles slide past each other as the attractive forces weaken

The particles stop moving altogether

The particles move apart and stay in a fixed pattern

The particles are still held together strongly and can't move

Why do particles in a solid take up more space when heated?

The particles vibrate more as they gain energy

The attractive forces become stronger

The particles are getting larger

The particles break apart from each other

Which of the following best describes the particles in a solid after it melts into a liquid?

They can move and slide past each other

They remain in a fixed position

They are farther apart and no longer touch each other

They stop vibrating and stay still

What is surface run-off?

Water that flows directly across the ground into rivers and lakes

Water that evaporates from plants
