Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.

All cells are separated from their surrounding by a cell membrane. The cell membrane regulates what enters and leaves the cell and also aids in the protection and support of the cell. A cell membrane is similar to the walls surrounding your house.

In plants the cell membrane is surrounded by a cell wall. The cell wall is outside the cell membrane, and its purpose is to help the membrane protect and support the cell. Since the cell wall is very porous, water, oxygen,…show more content…

Chromosomes contain the genetic information that must be passed to each new generation of cells. Chromosomes are what you pass on to your children to make them who they are, it’s the DNA of a cell.

The cytoplasm is the area between the nucleus and the cell membrane. The cytoplasm contains many important structures. This area is basically the main place where you will find structures that help the cells stay alive.

Mitochondrion is an importance structure that lies in the cytoplasm area. Mitochondrion is the plural word for mitochondria, which is the key organelle that converts energy from one form to another. Mitochondria changes the chemical energy stored in food into compounds that are more convenient for the cell to use. The mitochondrion contains two special membranes. The outer membrane surrounds the organelle, and the inner membrane has many folds that increase the surface area of the mitochondrion.

Ribosomes are the structures in which proteins are made. Cells that are active in protein synthesis are often crowded with ribosomes. Ribosomes are composed of RNA and protein. Some ribosomes are attached to the membranes, and some are free in the cytoplasm. Ribosomes are among the smallest of organelles. They are no larger than 25 nanometers in diameter. A nanometer is equal to one billionth of a meter.

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically
