Eukaryotic Cells

• Eukaryotic cells are cells that have a nucleus and organelles with a membrane. • Eukaryotic cells differentiate depending on what job they do.

• Organelle – Little organ

• Structure in the cell with a special function and or job.

• Cell and Plasma membrane

• Surrounds the cell wall to keep materials in and or out selectively permeable

• Protects the cell

• Allows cells to communicate with other cells

• Allows the cell to move

• A phosopholipid bilayer

• Cytoplasm and Cytosol

• Jelly- like material that fills the cell and surrounds organelles

• Many cells processes happens here (glycolysis)

• Many molecules are stored here (amino acids)

• Nucleus

• The control center of the cell

• Holds DNA and protects it

• Surrounded by a membrane called the nuclear membrane

• Has pores to let material move in and out

• Most obvious organelle in the cell

• Nucleous

• Found in the nucleus

• Make ribosomes

• Chromatin (Loose DNA)

• Instructions for making proteins/traits

• Ribosome

• Made by the nucleus

• Make proteins

• Found free floating or attached to rough endoplasmic reticulum

• Rough endoplasmic reticulum

• Extension of the nuclear membrane

• Covered with ribosomes

• Transport proteins to the golgi bodies.

• Smooth Endoplasmic reticulum

• Extends to the cell membrane

• No ribosomes

• Make and transport lipids used to make the cell membrane.

• Golgi Bodies

• Stacked organelle

• Packages and modifies proteins from the rough endoplasmic reticulum to leave the cell.

• Makes lysosomes, secretory vesicle and peroxisome

• Mitochondria

• Does cellular respiration to break down glucose into energy.

• Lysosome

• Made by the golgi bodies

• Contains enzymes

• Does intercellular digestion- stomach of the cell

• Cytoskeleton

• Protects the cell

•

Eukaryotic Cells Research Paper

elementary parts—the cells.” - Theodor Schwann. The cell is the basic structural biological unit of a living thing. The cell is really small, but as strong. They can replicate themselves without help. There are two types of cells that mostly differ from each other- the prokaryote and eukaryote. Prokaryotic means “before the nucleus.” This type of cell has this name mainly because it’s a type of cell that has no nucleus and that was on Earth before the nucleus evolved. A prokaryotic cell is the smallest…

Eukaryotic Cells Lab Report

characteristic eukaryotic cell can usually be made during the process of cell division. Elongated pieces of single double-stranded DNA are folded into characteristic formations or chromosomes. Each chromosome possesses a single double-strand of DNA as well as the necessary chromosomal packing proteins that serve as components of the folding process that give chromosomes their distinctive shape. The stage between the division of cells is known as interphase and is where a characteristic eukaryotic cell is for…

eukaryotic and prokaryotik cells Essay

Eukaryotic cells Cell membrane (or plasma membrane). This is a thin, flexible layer round the outside of all cells made of phospholipids and proteins. Its separates the contents of the cell from the outside environment, and controls the entry and exit of materials. The membrane is examined in detail later. Cytoplasm (or cytosol). This is the solution within the cell membrane. It contains enzymes for glycolysis (the first stage of respiration) and other metabolic reactions together with sugars…

cells- eukaryotic + prokaryote Essay

divided in pieces called cells. There are smaller pieces to cells that include proteins and organelles. There are also larger pieces called tissues and systems. Cells are small compartments that hold all of the biological equipment necessary to keep an organism alive and successful on Earth. A main purpose of a cell is to organize. Cells hold a variety of pieces and each cell has a different set of functions. It is easier for an organism to grow and survive when cells are present. If you were…

Nothing Such as a Typical Cell Essay

essay ‘There is no such thing as a typical cell’. Discuss this statement? There is no such thing as a typical cell. Things can be identical but different in their function, different in their structure and behaviour. For example twins can be identical but they are still two different people. So as for cells there are different types of cells even thought they are all called cells, but this does not necessary means that they are typically the same. Cells may carry out the same function but different…

Essay on Marie Antoinette

PLANT CELLS Some plant cells are the same types of organelles found in animal cells. The cytoskeleton is a network of proteins that’s constantly changing to meet the needs of the cell. The vesicles are small membrane-bound sacs that divide some materials from the rest of the cytoplasm and transport these materials from place to place inside the cell. The nucleus in the cell is the storehouse for genetic information and DNA. The nucleolus contains the DNA of the cell which this is used as…

Eukaryotic cell Prokaryotic cell Organelle - A structure or part that is enclosed within its own membrane inside a cell and has a particular function. Organelles are found only in eukaryotic cells and are absent from the cells of prokaryotes such as bacteria. The nucleus, the mitochondrion, the chloroplast, the Golgi apparatus, the lysosome, and the endoplasmic reticulum are all examples of organelles. Some organelles, such as mitochondria and chloroplasts, have their own genome (genetic material)…
