Cells

The basic unit of structure and function in a living things.

• chloroplast
• nucleus
• cell
• cell membrane

This thin layer protects the cell and regulates what substances enter and leave the cell.

• cell membrane
• cell
• cell wall
• golgi body

In a plant cell, a stiff wall surrounds the membrane, giving the cell a rigid, boxlike shape?

• cell membrane

• cell

• ribosome

• cell wall

These organelles capture energy from sunlight and use it to produce food for the cell.

• cell membrane
• chloroplasts
• cell wall
• ribosomes

A gel-like fluid in which many different organelles are found.

• cell membrane
• nucleus
• organelle
• cytoplasm

The network of passageways carries materials from one part of the cell to another.

• endoplasmic reticulum
• golgi bodies
• vacuole
• cell

This organelle receives materials from the endoplasmic reticulum and sends them to other parts of the cell.

• ribosomes
• mitchondria
• cytoplasm
• golgi bodies

Most of the cell's energy is produced within these rod-shaped organelles. This organelle is considered the "powerhouse" of the cell.

• ribosomes
• mitochondria
• vacuole
• endoplasmic reticulum

Directs all the cell's activities.

• mitochondria
• chloroplasts
• vacuole
• nucleus

A tiny cell structure that carries out a specific function within a cell.

• organelle
• cell
• nucleus
• ribosomes
