Cells are the Starting Point

Structure of generic animal cellAll living organisms on Earth are divided in pieces called cells. There are smaller pieces to cells that include proteins and organelles. There are also larger pieces called tissues and systems. Cells are small compartments that hold all of the biological equipment necessary to keep an organism alive and successful on Earth.

A main purpose of a cell is to organize. Cells hold a variety of pieces and each cell has a different set of functions. It is easier for an organism to grow and survive when cells are present. If you were only made of one cell, you would only be able to grow to a certain size. You don’t find single cells that are as large as a cow. Also, if you were only one cell you couldn’t have a nervous system, no muscles for movement, and using the internet would be out of the question. The trillions of cells in your body make your life possible.

One Name, Many Types

Animal and plant cells

There are many types of cells. In biology class, you will usually work with plant-like cells and animal-like cells. We say animal-like because an animal type of cell could be anything from a tiny microorganism to a nerve cell in your brain. Plant cells are easier to identify because they have a protective structure called a cell wall made of cellulose. Plants have the wall; animals do not. Plants also have organelles like the chloroplast (the things that make them green) or large water-filled vacuoles.

Different types of animal cells

We said that there are many types of cells. Cells are unique to each type of organism. Humans may have hundreds of types of cells. Some cells are used to carry oxygen (O2) through the blood (red blood cells) and others might be specific to the heart. If you look at very simple organisms, you will discover cells that have no defined nucleus (prokaryotes) and other cells that have hundreds of nuclei (multinucleated). The thing they all have in common is that they are compartments surrounded by some type of membrane.

CELL NUCLEUS - Commanding the Cell

The cell nucleus acts like the brain of the cell. It helps control eating, movement, and reproduction. If it happens in a cell, chances are the nucleus knows about it. The nucleus is not always in the center of the cell. It will be a big dark spot somewhere in the middle of all of the cytoplasm (cytosol). You probably won’t find it near the edge of a cell because that might be a dangerous place for the nucleus to be. If you don’t remember, the cytoplasm is the fluid that fills cells.

Every February we celebrate Valentine’s Day by giving flowers, candy and cards to those we love. We do this in honor of Saint Valentine. You may be wondering, "Who is St. Valentine"? Time to brush up on your Valentine’s history!

Legend has it that Valentine was a priest who served during third century Rome. There was an Emperor at that time by the name of Claudius II. Emperor Claudius II decided that single men made better soldiers than those that were married. With this thought in mind he outlawed marriage for young men in hopes of building a stronger military base. Supposedly, Valentine, decided this decree just wasn’t fair and chose to marry young couples secretly. When Emperor Claudius II found out about Valentine’s actions he had him put to death.

Another legend has it that Valentine was an imprisoned man who fell in love with his jailor’s daughter. Before he was put to death he sent the first ’valentine’ himself when he wrote her a letter and signed it ’Your Valentine’, words still used on cards today.

Perhaps we’ll never know the true identity and story behind the man named St. Valentine, but this much is for sure...February has been the month to celebrate love for a long time, dating clear back to the Middle Ages. In fact, Valentines ranks second only to Christmas in number of greeting cards sent.

Another valentine gentleman you may be wondering about is Cupid (Latin cupido, "desire"). In Roman mythology Cupid is the son of Venus, goddess of love. His counterpart in Greek mythology is Eros, god of love. Cupid is often said to be a mischievous boy who goes around wounding both gods and humans with his arrows, causing them to fall in love.

Gregor Mendel’s Pea Plants

Austrian monk and avid Gardener Gregor Mendel is credited for discovering why tall plants (in his case, pea) don’t always produce tall offspring, nor do smaller plants.

2012, LEAP YEAR!!


Fun cool facts about Leap Year Day February 29

OK, let’s learn how to say it correctly.
Someone born on February 29 was born on Leap Day,
or Leap Year Day. They were NOT born ON Leap Year.
Leap Year is the year we are in; like 2012 or 2016.

Anyone can be born IN a Leap Year. Leap Year lasts
all year. Leap Day Babies were born ON Leap Day.
THAT is what is rare. In fact, the odds are 1 in 1461!

You don’t have to be born on February 29 to enjoy Leap Day.
|It’s everyone’s extra day!

Twenty-eight days has February
A very light load for one month to carry
The other months have 2 and 3 more
Thirty and thirty-one being their big score

In Leap Years the days they do vary
Making 29 days in February


We are Leap Day babies,
not Leap Year babies.
Anyone can be born IN a Leap Year.
We were born ON Leap Day.
There’s a big difference there!
If you were born on February 29
You are a Leap Day baby.

You will hear the same questions for the rest of your life!
If you haven’t heard these yet, you will!  Be ready.

    1. When do you celebrate?
    2. How old are you really?
    3. What’s it like to not get a birthday?

Number 3 - Of course we get a birthday. We age, we
celebrate that age every year, and we "get" a birthday.

The question they are really asking is:

    What is it like to have a birthday that’s
    not on the calendar every year?

Just explain to them that you do "get" a birthday. Just
because it’s not on the calendar doesn’t mean you don’t
get one. It doesn’t mean we don’t age either.

Let them know what it feels like to you. Be honest.

Sometimes, when they know what it’s all about, they
wish they were a Leap Day baby too!


When speaking of your Leap-age, it is incorrect to say
you are 2 "years" old when you are really 8 "years" old.

You are 2 LEAP Years old. Or - even better, just simply 2.
Keeping it simple has the best impact.

When talking about a friend or relative born on Leap Day
it is best to say "This is my Aunt, she is only 5."

And watch the facial expressions change.

Don’t say "5 ’years’ old" that doesn’t make sense.

BUT, stopping at the number has a bigger impact.

I was born in 1960, but I turned 12 this last Leap
Year 2008! See the difference? It’s fun too. I will
be 13, again, next Leap Year 2012!
