Tissue attack!!!!

Well folks we got tissues! These tissues are made of lots of cells!

The are the four types of tissues are epitheial tissues, nerve tissues, connective tissues, and muscle tissues. 

Muscle tissues are made up of cells that can become shortened.  The muscles of the human body can be categorized into a number of groups which include muscles relating to the head and neck. Our body is made up of muscles.

 Connective tissues holds parts of your body together. They attach to your bones to help you move. They even make you stand up! More connective tissues are Tendons and ligaments.Tendons keeps the foot , hand,back, and leg to together. Ligaments do the other bones.

Epithelial tissues contain cells that are packed tightly together. Your outer layer of you skin is epithelial tissues.The lining of your air passage is too! Epithelial tissue lines the internal organs, helping them to carry out their functions and protecting other tissues in the organ. Is that cool or what? 

I have one thing to say about the nerve tissues. You know when you touch  something hot. Well when your hand moves away. That is nerve tissues! They send messages to your brain! Nerve tissue is  found in the brain, the spinal cord, nerves, and sensory receptors.

Tissues are freaky!
Whoa! This is a cool picture!
I hope you learned about tissues!
Well that is all for now!

Plant like Protists V.S. Plants!!!

Well folks we have plant like protists and plants but plant like protists are not plants!! We are going to look at how they are alike. Plant like protists are not plants because they don't have leaves or roots. Also plant like plants are multicellular and plant like protists are singled celled.

Plant like protists produce there own food just like plants! You might be wondering what is a protists? Well protists are one of the six types of kingdoms in the world.They are microscopic creatures. They live every where!!!  Now let's explore different types of algae! Let's go!

This is green algae. This algae can make air. They make 75% of our air!
This is dionflagellates. They make red tides.

This is brown algae.These guys are seaweed.

Here is cool red algae!

 This red plant are one of the oldest groups of eukaryotic algae, and also one of the largest, with about 5,000-6,000 species  of mostly multicellular.

 Last photo... Here is euglenoids
Euglenoids have tails to move.

Now for the video I promised. Its is about protist in action!

Another way protists and plants are alike is they both need water and need sunlight.
Moving on from protists we have... Algae!
 Algae are a large and diverse group of simple, typically autotrophic organisms, ranging from unicellular to multicellular forms, such as the giant kelp that grow to 65 meters in length! Wow! I did not know that! Yes there are red,green and brown! This video is about man made algae! Let's watch it!

Algae are found in the fossil record dating back to approximately 3 billion years.
That is cool! Do you want to know a cool fact about algae?
It makes air like plants do!!!  They also make red tides(Bloody tides yuck!).Well that is it thanks for watching and reading my article.

Protists smack down!!!!

Protists are not bacteria because they have a nucleus and bacteria don't. Amoeba have a fake foot to help them move around. They eat bacteria. They have to get food like we do! We have a food store and they don't!! Paramecium have a nucleus and they have to get their food.They are different, Paramecium do not have a fake foot.
See video.

Cool right? This fake foot is really cool!!!

Protists were traditionally subdivided into several groups based on similarities or movement.
Paramecium and amoeba are alike because they have a nucleus and they attack (or hunt) for their food.
We don't do that! They both feed of bacteria.

Well that is pretty much it... One thing, they are different sizes!!! Bye!!! ;)
See you next time!

Protists smack down!!!!

Protists are not bacteria because protists have a nucleus and bacteria don't.
Amoeba have to get their own food like attack there food! So do Paramecium!
See picture.

The inside of a bacteria!

The bacteria is very complex. The cell   (one celled creature) has an flagella to make it move. The flagella is a tail that makes the bacteria move.
See picture

Cool right? The cell membrane is what keeps the cell together.
The cell wall is the protector of the cell,so the bacteria has some defence.
The chromosome is it's DNA, so when the cell splits it is like this.
See video

A plasmid is a DNA molecule that is separate from, and can replicate independently of, the chromosomal DNA.[1] They are double stranded and, in many cases, circular. Plasmids usually occur naturally in bacteria, but are sometimes found in eukaryote organisms.
Ribosomes are the components of cells that make proteins from amino acids.
 The chromosome is it's DNA, so when the cell splits it is like this. Well that is it That is..... I forgot! watch this video!

Has you saw bacteria grow fast! Well Thanks for listening and have a good day.
