Cell = Life

Cell = Life

1.   What makes something living?

- They reproduce.
- They need energy.

- They react to their environment.

- They grow.

- They get rid of wastes.

2.   The cell is the smallest unit of life.

Cell ® ® ® ® Tissue ® ® ® ® Organ ® ® ® Organ Sytem ®

­                             - cardiac              - heart                     - digestive

Unicellular        - skin (epithinal)  - stomach         - circulatory

Organism         - muscle               - brain               - nervous

                         - nervous tissue

Organism

Multicellular

How is a single cell like a multicellular organism?

         - A single cell has specialized parts (organelles) to do different things.

         - A multicellular organism has specialized cells to do different things.

3. Identify the ORGANELLES of plant + animal cells. What are the JOBS?

         Animal cell:

         - Ribosome

         - Cytoplasm

- Cell membrane

         - Lysosome        

         - Golgi body

         - Nucleus

         - Vacuole

         - Mitochondrion

         - Endoplasmic reticulum

         Plant cell:

         - Mitochondrion

         - Cytoplasm

         - Endoplasmic reticulum

         - Chloroplast

         - Ribosomes

         - Golgi body

         - Cell membrane

         - Vacuole

         - Nucleus

         Jobs:

- Ribosome: Make proteins

         - Cytoplasm: Holds organelles, water, and other life supporting things Ariel- “Everything in a cell in the area between the nucleus membrane and cell membrane”

         - Cell membrane: Surrounds each cell to separate the inside of the cell to what’s around it

         - Lysosome: Recycle broken down organelles

         - Golgi body: Sorts protein into vesicles (wrapped membrane)

         - Nucleus: Controls what goes on inside the cell

         - Vacuole: Temporarily store waste sometimes

         - Mitochondria: Make energy

         - Endoplasmic reticulum: Transports protein from ribosomes to the Golgi body

         - Chloroplast: (only in plant cells) Changes the energy from the sun into chemical energy

First post

Science!!! 

Science is going to be really cool this year. We are using twitter and blogger and were told to take pictures during classes and many more tech things. Science this year is going to be very different to my science classes in the past. We always learnt in science by reading text books and having tests on what we read. But by being hands on and using all this tech stuff, I think we are going to learn a lot more.

I can't wait for the rest of the year of science!
