To build a wall you need lots of bricks like that all living things are contained with tiny units called cells which makes them a living thing. Unlike anything cells are the smallest structure in any living thing. We can’t see cells through our eyes so we use microscopes.
Plant and animal cell
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles. Both also contain similar membranes, cytosol, and cytoskeletal elements. Animal cells and Plant cells have features in common such as a nucleus, cytoplasm, cell membrane, mitochondria, lysosomes, peroxisomes and ribosomes. Only Plant cells have a cell wall because of that Plant cells get a shape.
What is a cell
A cell is a tiny structure with its own protective skin called a cell membrane but that’s not the only protective skin it has, it also has a Plasmodesmata, a Plasma membrane and a cell wall. Inside a cell is even smaller parts called organelles.
They are Mitochondria, Centrioles, Vesicles, Nucleus, Nucleolus, Cytoplasm, Endoplasmic reticulum, and Golgi apparatus.
Inside a cell
When a cell is in a resting state there is, something called Chromatin in the nucleus. Chromatin is made of DNA, RNA, and nuclear proteins. DNA and RNA are the nucleic acids inside of a cell.
The structure of DNA and RNA is a double helix
but sometimes it’s a helix. The alphabetical of
DNA is ATGCTAATCGGC.
