Cells

Human CellsOrganelles are parts of the cell which are adapted and/or specialized for carrying out one or more vital functions, analogous to the organs of the human body (such as the heart, lung, and kidney, with each organ performing a different function).

Eukaryotic cells Eukaryotic cells have a defined nucleus containing genetic material organized in linear chromosomes. They have various specialized organelles that carry out the processes and energy transfers necessary to sustaining life. Animal, plant, fungi, and protest cell types are very different from each other.

ContainAnimal cells and plant cells both contain:cell membrane, cytoplasm, and nucleus.Plant cells also contain: chloroplasts, vacuole, cell wall

Two basic cell typesAll cells in living things can be classified in one of two basic cell types: prokaryotic and eukaryotic. Prokaryotic cells tend to be small, primitive, and independent of other cells and encompass bacteria, blue-green algae, and archae. Eukaryotic cells are larger, more complex types found in all other plants, animals, fungi, and protists.

Some typesNerve cells, red blood cells, white blood cells, muscle cells, skin cell, sperm cell, cheek cells, ciliated cells, root hair cells, epithelium cells

Prokaryotic cellsA cell is the smallest part of a living thing and is the setting for all the chemical processes that are necessary to life. Prokaryotic cells are the most simple cell forms, having no nucleus or organelles. These cells have no chromosomes; circular plasmids contain the genetic material. Some prokaryotic cells do not need oxygen to carry out life processes.

Cells

What are human cells made of?Two-thirds of a cell is water, which means that two-thirds of your whole body is water. The rest is a mixture of molecules, mainly proteins, lipids and carbohydrates. Your cells turn the raw materials in the food you eat into the molecules your body needs, using thousands of different chemical reactions.
