See the below image for the Cell structure and function diagram. By: Daniel Nelson | November 20, 2017. The cell structure is defined by the cell membrane, the cytoplasm, and the nucleus. A cell is the smallest unit of life and its structure helps it to work as the basic building block of biology. The cell function is to keep all of the functions of the body performing as intended.

Some functions performed by cells are so vital to the existence of life that all cells perform them (e.g. cellular respiration). Others are highly specialised (e.g. photosynthesis). Figure 2.9 shows a two-dimensional drawing of an animal cell. The diagram shows the structures visible within a cell at high magnification.

The roles of the organelles within the cells need to be introduced and relate structure and location of organelles to their function. Cells differ in size, shape and structure and therefore carry out specialised functions. Link this to tissues.

See the below image for the Parts of animal cell diagram. The Parts Of An Animal Cell. There are 13 main parts of an animal cell: cell membrane, nucleus, nucleolus, nuclear membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrioles, cytoskeleton, vacuoles, and vesicles.

Animal Cell Structure 1 Nucleus. The nucleus contains all the genetic material in a cell. … 2 Ribosomes. Ribosomes are organelles found in both prokaryotic and eukaryotic cells. … 3 Endoplasmic Reticulum. … 4 Golgi Apparatus. … 5 Lysosomes. … 6 Mitochondria. … 7 Cytoplasm. … 8 Cytoskeleton. … 9 Cell Membrane. …

All animal cells are made up of various different parts. These parts are called subcellular structures. The parts of a cell that have a specific function are called organelles. Let’s look at each of these in more detail. All animal cells have a plasma membrane. This is a barrier that surrounds the cell and holds it together.

See the below image for the Human cell structure diagram. Parts of the Human Cell. The cell contains various structural components to allow it to maintain life which are known as organelles. All the organelles are suspended within a gelatinous matrix, the cytoplasm, which is contained within the cell membrane.

Human Cell Diagram, Parts, Pictures, Structure and Functions. The cell is the basic functional in a human meaning that it is a self-contained and fully operational living entity. Humans are multicellular organisms with various different types of cells that work together to sustain life.

See the below image for the Cross section of a plant cell diagram. CROSS SECTION OF A LEAF. Spongy Mesophyll: These cells are smaller than those of the palisade mesophyll and are found in the lower part of the leaf. They also contain chloroplasts, but not quite as many. These cells have large air spaces between them that allow carbon dioxide and oxygen to diffuse between them.

The parts of a plant cell and plant cell components, which will be discussed, are plant cell wall, plant cell membrane, smooth endoplasmic reticulum, ribosomes, rough endoplasmic reticulum, vacuole, nucleus, peroxisomes, Golgi apparatus, mitochondria, cytoplasm, cytoskeleton, and plastids. The outermost portion of a plant cell is the cell wall.

It is located outside the cell membrane. It comprises proteins, polysaccharides and cellulose. The primary function of the cell wall is to protect and provide structural support to the cell. The plant cell wall is also involved in protecting the cell against mechanical stress and to provide form and structure to the cell.

The structure of a cell includes various organelles that perform all crucial functions such as the production of energy, replication, transport of materials, etc. Cells of prokaryotes differ from eukaryotes based on their structure.
