Vaifoa- Cells

Greetings and welcome to my new blog post! Throughout this term in Science with Mr Tyagi, we've been learning about Living and Non-living, Cell structure and also the Functions of cell parts which are (organelles.)  Our task for today was to write a blog post to show what we've learnt within these five weeks. I've created two diagrams to show that I'm able to learn and know the different cells and their functions within the Plants and Animals. Check the out the diagrams down below if you insist. Please feel free to leave a comment, Thank you very much for visiting my blog, I appreciate it a lot!

LIVING                                                 Non-Living
They are able to grow
They are not able to grow
They are able to breathe
They can’t breathe
They can move on their own
They can’t
They have sensory organs
They don’t unfortunately
They can produce offspring (reproduce)
They can’t

Livings things are created/made up out of “cells.” They are able to maintain to balance… be stable betwo things as of being dependent on each other. Livings things are also able to move, feed, grow, reproduce, excrete waste and also breathe… unlike Non-living things which cannot indeed breathe… for example, a car can’t breathe because they don’t have any organs to produce oxygen. Non-living things are not able to move on their own but Living things are, they don’t have all of these characteristics. It is defined that life uses a body of attribution which living organisms share.

PLANT CELL:

The differences between these two cells “Plant Cell” and “Animal cell” is that there is a total difference in size construction... there are a few difference main structures between these cells, as it concludes the vacuole in the Plant cell and in the Animal cell, it has a more than one. As of animals and plants, they are different but they are still a living thing in life. Plants are able to move around in some cases but not as swiftly animals, it takes quite a long period of time for them to move on their own.

Cell membrane: Very thin transparent sheet that holds everything inside & controls what comes in & out.
Cell wall: Made of cellulose & only found in plants, thick & strong, provides strength for the plant.
Nucleus: Usually a small dark circular spot. The control centre for the cell & contains genes.
Cytoplasm: Watery jelly like substance which fill most of the cell. It holds the cell organelles and contains nutrients & chemicals.
Vacuole: Water filled bubble that helps to keep the cell firm.
Chloroplasts: Small green structures found only in the green part of plants. Makes sugar for the plant.
Mitochondria: The part of the cell that does respiration to give the cell energy.

Names of 10 Things
Living or Non-living
1. TableImage result for table
A table isn’t a living thing and the reason why, is because it can’t grow, move on it’s own, reproduce, doesn’t have any sensing organs and can’t excrete or respire.
2. CatImage result for cat
A cat is a living thing because it can grow, reproduce more of it’s kind, is able to excrete waste and it is able breathe. Cats have eyes which allow them to see and sense their surroundings.
3. BagImage result for bag
A bag isn’t a living thing and the reason why is because a bag needs someone to carry it around… it can’t move on it’s own and it can’t breathe, so it’s not living.
4. DoorImage result for door
A door can’t respire or excrete waste because it doesn’t have any organs like a living thing, it can’t breathe, it’s a man-made object to use to go into places. A door doesn’t have eyes so they aren’t able to seek/look around at the environment that they’re in.
5. DogImage result for dog
A dog is indeed a living thing because it can grow, move, reproduce, sense, Dogs are able to eat food and excrete the waste from digesting the food from the stomach.They have eyes that allow them to see certain objects/things moving around them, They can adapt.
6. PlantImage result for plant
A plant is a living thing because it is able to grow, it can move when it turns to the sun so they can get energy. They are also able to soak up water so they can live.
7.  WhiteboardImage result for whiteboard
A whiteboard isn’t able to grow, reproduce, respire or excrete waste, doesn’t have any sensing organs so they are well known to be a non-living thing. It is a man-made object that was created for school work… write things on it.
8. WormImage result for worm
A worm is a living thing because it’s able to reproduce so there can be more of it’s kind and yet… they’ve done a brilliant job of reproducing, they can breathe, they are able to digest… excrete waste so obviously they are a living thing. Worms are able to sense their surroundings but they can’t see because they don’t have any eyes to see where it’s going. Basically, they just sense their ways around things.
9. PaperImage result for paper
Paper is unfortunately not a living thing because it was created from people...from trees. They can’t breathe nor move on it’s own but they are able to move from the wind blowing them because they are light weighted. They also aren’t able to excrete.
10. WallImage result for wall
A wall isn’t a living thing because it was created from mankind and they aren’t able to move on it’s own, can’t reproduce… obviously, can’t digest or excrete waste nor eat anything because they are not a living thing. The wall doesn’t have any eyes to see or sense its surroundings. It can’t move because it’s been built/created to be stable.
Living and Non-living Things:

1. What are the seven characteristics of living things?
The seven characteristics of living things are...
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition.

2. Describe the two groups of non-living things…
The first group is those which were never part of a living thing, such as stone and gold. The second group are those which were once part of living things. Coal is a good example, it was formed when trees  died and sank into the soft ground. Paper is non-living but it is also made from trees. Jam is also non-living but it was made from the fruit of a plant. So these are all the examples of non-living things.

Unicellular: Those organisms which are made up of single cell are known as unicellular organisms for example “Amoeba.” It consists of an individual cell.

Multi-cellular: Those organisms which are made up of more than one cell are known as multi-cellular organisms like plants, cat, dog & us.
