Also got from notes. ( some things may sound the same just a little different.)
"Is the process in which cells use oxygen to release energy stored in sugars such as glucose."
You may know all cells release energy. But maybe you didn't know this Glucose and the sugars are the power and source and the cell.
Most of this energy is provided by Cellular respiration.
It also takes place in the Mitochondria.
Plant and animals release this same energy.
These are the starting materials sugars-) glucose-) and oxygen. All of those enter the Mitochondria.
And the chemical reaction to that make new materials. Then as you might have guessed it releases energy.
The products are energy-) carbon dioxide -) and then water. Energy is also used to build,repair and reproduce the cells.
All Info got on this CELLULAR RESPIRATION notes

Waste elimination in cells
Organisms rid the cell of harmful things that could damage the cell.
if your in a classroom and their are more people on that other side what would you do? You would move to the less filled area than the more filled area.
Here is an ex: Passive transport & active transport Diffusion and osmosis are both passive transport.
If you don't know what diffusion is it is when the molecule spread out until they are even.
That is very important for cell functions.

Photosynthesis
OK, let's get into this photosynthesis.
This is the way plants make their own food. They make it by the light of the sun and water from the ground there is also more to how they make food. Tet me show you a video that you may have seen before.
I hope that helps you.

Did you know that cell wall's are only around plant cells? And they are also made of cellulose. You can think of cellulose as a frame of a picture it protects the cell in order for it to survive.
The cell wall also provides the plant to maintain it's shape.This also allows the plant to grow great heights. Unlike the plants they don't have skeletons like we do so they use the cell wall to keep up right.
When it is a smaller plant it is slightly elastic. If wind pushes them over they go right back up.
If you are thinking that nothing can hurt the plant like the cell wall is a barrier around it your wrong. It still can get hurt.
There are small holes that let ions, waste and nutrients pass through the cell.
These hole's are called Plasmodesmata.

Chromosomes
Chromosomes are like a computer it helps the cell grow, Think of it as giving it updates.
it also makes it thrive and reproduce. Just like we are made up of DNA so are they too.
"Segments of DNA in specific patterns are called genes." "Your genes make you who you are." "You will find the chromosomes and genetic material in the nucleus of a cell." " In prokaryotes, DNA floats in the cytoplasm in an area called the nucleoid. "
BOLDED QUOTE'S FROM link down below.

Did you know that not all Chromosomes are visible? They are usually sitting around their buddy called the chromatin, they are uncoiled and loose strands. When they start to reproduce they reduce and wrap around tightly together.

Cell membrane.
Cell membrane
Think of it as a soft squishy jelly doughnut. The cell membrane has a liquid substance inside. Everything that is in this cell membrane stays in there. There are hole in this Membrane that let stuff go in and out through this cell. It doesn't let any bad thing in. It also keeps the good stuff in.
If you haven't guessed the cell membrane is NOT solid! And if you don't remember what the smallest thing is here you go. The answer is cells. Every little thing in life has cell even you and me. The membrane is no different it's the same.

"Compounds called proteins and phospholipids make up most of the cell membrane."

"The phospholipids make the basic bag. The proteins are found around the holes and help move molecules in and out of the cell."

I think you would need some fun after me rambling on and on so feel free to pause this video at times you need to.

Click the pic. all rights goes to plantendomembrane on youtube. Can you also tell me what other organelle's you see in that video?
