Atoms are smaller than cells. In Fact, they make UP cells. Can they be alive? How do you know?

Because cells are the smallest, basic, unit of life. Cell theory!

Maggie read that some plants grow better if the soil is acidic. She can't believe that a plant can grow when exposed to acid. Maggie decides to test if the plants she has will grow better when acid is added to the soil. She puts two plants in the same soil, puts them in the same location so that they both get the same sunlight each day, are at the same temperature, and she makes sure they get the same amount of water. However, Maggie puts a tablespoon of vinegar in the water she gives to one of the plants. She measures the growth of the plants every week for five weeks and records the results in a data table. IV, DV, Control

IV - plant growth DV - Acid Control - unchanged plant without acid

Donna has observed that her father can control the speed of their grandfather clock by adjusting the height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster when the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the time it takes for the pendulum to swing twenty times when the weight is moved to its lowest position. Donna begins to move the pendulum up by 1 cm and continues to measure the time for twenty swings of the pendulum. Donna records her data.

IV - time for 20 swings DV - height of the pendulum Control - normal length

Which organelle would you expect to find in an animal cell but not in a plant cell?

Lysosome

What are some things that ALL cells have?

Membrane, DNA, cytoplasm

A cell has a nucleus, chloroplasts, and a hard cell wall. What kind of cell is this? (two answers)

Plant cell, Eukaryote

Preexisting cells

A cell that has DNA and ribosomes, but no other organelles is a _____________________

Prokaryote

This type of cell does not have a nucleus

Prokaryote

When an animal eats food, it gets energy. This energy is distributed to every part of the animal. What part of the cell theory is this showing?

The flow of energy in living organisms occurs in cells.

What is an example of a unicellular organism

Yeast cell, bacteria, some fungus
