- Cell Structure
- The cell is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life that can replicate independently, and cells are often called the "building blocks of life".

- Fungi
- Bacteria
- Fungi
- Animals
- Controls entry and exit of substances.
- Cell Wall
- Single celled organisms are organisms that are made of one cell, which contains all the organelle
- Multi cellular organisms such as plants and animals have more than one cell type.
- All the required functions are divided up between gorups of cells and each group is specialised to carry out one job particularly well. (specialisation)
- Muscle Cells
- Blood Cells
- Phloem Cell
- Xylem Cell
- Root Hair Cells
- Their job is to absorb water.
- They have adapted to have a large surface area and absorb more water.
- Their job is to absorb water.
- Their job is to transport water.
- It is shaped like a hollow tube to allow water to travel from the roots to the plant.
- Root Hair Cells
- Their job is to transport food in plants.
- It has adapted to be shaped like a sieve to allow glucose to pass from cell to cell
- Xylem Cell
- Their job is to transport oxygen.
- It has adapted to have a large Surface Area
- Phloem Cell
- Their job is to perform movements.
- It has adapted to contract and expand.
- Blood Cells
- Muscle Cells
- System
- Organ

- All the required functions are divided up between gorups of cells and each group is specialised to carry out one job particularly well. (specialisation)
- Stem cells are special cells that have the potential to turn into any type of specialised cell.
- Embryonic Stem Cells
- These stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells.
- Adult Stem Cells
- These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body.
- Stem cells are important for the development of the human body. They help with the growth and repair of cells.
- Embryonic Stem Cells
- In plant cells, division with mitosis only occurs in certain areas called growing points of meristem.
- Meristem are found at the tips of the roots and shoots of the plant and in between the phloem and xylem tissues
- The cells in the meristem have the ability to divide over and over again to produce non-specialised cells.
