  1. Cells are the smallest unit of life that can replicate independently, and are often called the "building blocks of life". The study of cells is called cell biology. Cells consist of a protoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.

The differances in a plant cell and animal cell

Aminal cells dont have a cell wall

Animal cells are round (or irregular shaped)

Plant cells are rectangular

Animal cells have one or more than  vacuoles, and plant cells only have one central vacuoles taking up 90% of cell volume.

Reasons for cells

Blood cells: red blood cells carry thingd through the blood steam and white blood cells are sickness fighters

Function of Cartilage Cells:Provides    Flexible Support
Serves as sliding area of joints
Essential for the development and growth of long bones

Neurons cells: are highly specialised to transmit messages from one part of your body to another. All neurons have a cell body and one or more fibres.


The outermost layer of the stomach surrounding the muscularis layer is the serosa – a thin serous membrane made of simple squamous epithelial tissue and areolar connective tissue. The serosa has a smooth, slippery surface and secretes a thin, watery secretion known as serous fluid.

The human cerebral cortex is a thick layer of neural tissue that covers most of the brain. This layer is folded in a way that increases the amount of surface that can fit into the volume available. The pattern of folds is similar across individuals, although there are many small variations.

ways the body works

Your digestive system is uniquely constructed to perform its specialized function of turning food into the energy you need to survive and packaging the residue for waste disposal. To help you understand how the many parts of the digestive system work together, here is an overview of the structure and function of this complex system.

Think of you circulatory system as a packed string of interstate highways: every vehicle on the road has a very specific and helpful function. So long as no one starts backing up traffic, everyone gets where it needs to go in an orderly fashion.

Respiratory system consists of the organs that help to breathe. Respiration also known as breathing is the process which delivers oxygen from the external atmosphere to the body and removes the carbon dioxide from body and expels out. The main parts of the respiratory system and their functions are as follows

How it all works

Your body works similarly to a machine, with different systems that make up your body and allow it to run effectively. Like a machine, if one system is not running properly, your whole body will be affected. These systems perform different tasks in the body and encompass different organs.

Paramecium  is a genus of unicellular ciliated protozoa, commonly studied as a representative of the ciliate group. Paramecia are widespread in freshwater, brackish and marine environments, and are often very abundant in stagnant basins and ponds.

they are differnt because it live in a watery area and commonly studied as a representative of the ciliate group.
