100

The basic unit of structure and function in living things.

What is a cell?

100

This is a tiny cell structure that carries out a specific function within the cell.

What is an organelle?

100

This organelle converts energy stored in food to the energy a cell can use to live and function. It is known as the 'powerhouse' of the cell.

What is the mitochondria?

100

Every cell is surrounded by this.

What is a cell membrane?

100

This is the type of cell transport that DOES NOT require energy.

What is passive transport?

200

This invention made the discovery of cells possible.

What is a microscope?

200

This is the outer layer of a plant cell that provides support and protection.

What is a cell wall?

200

This organelle is found in the cells of plants and some other organisms; it captures energy from sunlight and changes it to an energy that cells can use in making food.

What are chloroplasts?

200

This means that some substances can cross the cell membrane while others cannot. 

What is selectively permeble?

200

This is the type of transport that DOES require energy.

What is active transport?

300

A widely accepted explanation of the relationship between cells and living things.

What is the cell theory?

300

This is the organelle that contains the cell's genetic information and controls the cell's activities.

What is the nucleus?

300

These organelles contain substances that break down large food particles into smaller ones. They also break down old cell parts and release them as waste.

What are lysosomes?

300

This is the movement of molecules from an area of high concentration to an area of lower concentration.

What is diffusion?

300

This process takes particles into the cell by changing shape and engulfing the particles.

What is endocytosis?

400

True or false: All living things are made of cell(s).

True

400

This organelle is a network of membranes that processes proteins and lipids. Sometimes there are ribosomes attached.

What is the endoplasmic reticulum?

400

This organelle stores water, food and other materials. It is larger in a plant cell.

What is a vacuole?

400

This is the diffusion of WATER molecules across a selectively permeable membrane.

What is osmosis?

400

List the three types of passive transport.

What are diffusion, osmosis, and facilitated diffusion?

500

Light microscopes focus light through lenses to produce magnified images, while electron microscopes use this.

What are beams of electrons?

500

This organelle receives proteins and other materials, packages hem, and distributes them around the cell.

What is the Golgi apparatus?

500

A group of cells that work together to perform a specific function.

What are tissues?

500

This is a type of passive transport that utilizes a protein channel.

What is facilitated diffusion?

500

The odor from a skunk can be sensed from farther away due to this.

What is diffusion?
