100
Cells contain many of these organelles that are responsible for making proteins for the cell.
What are ribosomes?

what are the 3 postulates of cell theory?

1. All living things are made of cells.

2.Cells are the basic units of structure and function in living things.

3.Living cells come only from other living cells.

100
Provides protection and support to the cell membrane in plant cells.
What is the cell wall?

What is the concentration gradient?

The concentration gradient is the difference in concentration between 2 areas.

100

What is diffusion?

The movement of particles from an area of high concentration to an area of low concentration.

200
These organelles break down food molecules to produce energy. They are the powerhouse of the cell.
What are mitochondria?

Who discovered cells and when?

What did he use?

Robert Hooke first discovered cells in 1665. He originally did not think they were alive.

A microscope

200
Digest food particles, wastes, cell parts and foreign invaders. This organelle is the clean-up crew of the cell.
What are lysosomes?
200

What does concentration gradient have to do with diffusion?

Diffusion is a natural process that always occurs down a concentration gradient.

What is osmosis?

The diffusion of water across the cell membrane.

300
This organelle is the control center of the cell, and is where DNA is stored.
What is the nucleus?
300

Tiny hairs found on a cell that work together to move the cell or the fluids around it.

Cilia

300
This organelle provides storage for food, water and wastes.
What is a vacuole?
300

long tail like structure that projects out from the cell with tiny hairs called cilia?

Flagella

300

What materials enter and leave cells by diffusion?

Materials such as oxygen carbon dioxide and glucose enter and leave cells by diffusion.

400
This organelle is only found in plant cells, and contains chlorophyll that traps sunlight to make food for plants.
What is chloroplasts?
400

What role does diffusion play in cells?

Diffusion plays an important role in how living things get energy and get rid of waste.

400
Passageways that transport proteins, make lipids, and break down harmful substances. This organelle is the highway of the cell.
What is the ER/endoplasmic reticulum?
400

Small structure within cell, only visible with microscope, work tg to contribute to cells life

What acts as the solovent in cells?

Water.

Sugars, proteins and salts are common solutes in cells.

500
This organelle surrounds all cells and keeps the cytoplasm inside. It is the gateway to the cell.
What is the cell membrane?
500

What is a cell?

The basic unit of life in all living things.

500
This organelle packages and transports materials out of the cell. It is known as the FedEx of the cell.
What are Golgi bodies?
500

Watery fluid that makes up most of the cell volume. Keeps everything in place. Stores waste until it can be disposed of.

Cytoplasm

Where is water stored in a cell?

Vacuoles. 

When a cell needs water for a cellular process, water moves from the vacuole to the parts of the cell were it is needed.
