This organelle controls the activities of the cell and contains genetic material.

What is the nucleus?

100

A cell with a flexible, round shape is most likely this type of cell.

What is an animal cell?

100

The smallest level in this organization sequence: cell → tissue → organ → organ system → organism.

What is a cell?

100

Cells produce the energy they need through this process.

What is cellular respiration?

100

If a cell were a school, the principal's office would represent this organelle because it controls activities.

What is the nucleus?

100

Dutrochet proposed that these are the basic units of living things.

What are cells?

200

This organelle produces usable energy for the cell.

What are mitochondria?

200

A cell with a rigid, fixed shape is most likely this type of cell.

What is a plant cell?

200

A group of similar cells working together is called this.

What is tissue?

200

This process is common to all cells and allows them to carry out life functions.

What is obtaining and using energy?

200

If a cell were a school, the school's walls and doors would represent this structure because it controls what enters and leaves.

What is the cell membrane?

200

The basic unit of life is this.

What is a cell?

300

This organelle breaks down waste and old cell parts.

What are lysosomes?

300

These two structures are found in plant cells but not animal cells.

What are the cell wall and chloroplasts?

300

A group of tissues working together to perform a specific job is called this.

What is an organ?

300

Glucose first begins to break down in this liquid part of the cell before the materials move to the mitochondria.

What is the cytoplasm?

300

In the school analogy, the cafeteria could represent this organelle because cells need materials from food to make energy.

What are mitochondria?

300

An amoeba differs from a sunflower because the amoeba is made of this many cells.

What is one cell?

400

This structure controls what enters and leaves the cell.

 What is the cell membrane?

400

This structure gives plant cells support and helps them keep their shape.

What is the cell wall?

400

The heart is an example of this level of organization.

What is an organ?

400

If the mitochondria stop working properly, the cell would have trouble producing this.

What is usable energy?

400

The school walls that provide support and protection are most similar to this plant-cell structure.

What is the cell wall?

400

A sunflower is made of this type of organism because it contains many cells.

What is a multicellular organism?

500

This organelle allows plant cells to capture sunlight and make food.

What are chloroplasts?

500

Plant cells contain this organelle because it captures sunlight to help the plant make food.

What are chloroplasts?

500

Put these in order from least complex to most complex: organ, cell, organism, tissue, organ system.

What is cell → tissue → organ → organ system → organism?

500

The nucleus controls activities, the cell membrane regulates substances, and the mitochondria provide this.

What is usable energy for cell processes?

500

The school analogy helps show that different parts of a cell must work together because the cell is this type of system.

What is a living system?

500

Different organelles are required because each one performs different jobs that work together to keep the cell alive.

What is division of labor among organelles?
