Ribosomes cell structure that makes protein. Protein is used for repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.

Lysosome You will find organelles called lysosomes in nearly every animal-like eukaryotic cell. Lysosomes hold enzymes that were created by the cell. The purpose of the lysosome is to digest things. They might be used to digest food or break down the cell when it dies.

Mitochondria Vila Chu 4th period Mitochondria are used to produce the energy currency of the cell, ATP, through respiration, and to regulate cellular metabolism. They are small organelles floating free throughout the cell. Mitochondria are located in the cytoplasm of cells along with other organelles of the cell. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. Vila Chu 4th period

Lysosome Location Function Scattered in the cytoplasm within the cell membrane Serves to kill and digest bacteria with in the cell.

Chromatin WHAT IS IT? Chromatin is made of DNA, RNA, and nuclear proteins. WHAT’S THE FUNCTION? The function of chromatin is to condense the DNA down so that it will fit inside the nucleus. It protects the DNA structure and the sequence and also helps transcribe the RNA. WHERE IS IT LOCATED? The Chromatin is located in the nucleus of the cell.

Function: Ribosomes build Protein for the cell Angelique Estrada 4th pd Structure: For every ribosome, there are 2 parts called subunits. In this subunit there is a 60-S (large) and a 40-S (small). Function: Ribosomes build Protein for the cell   Location: Ribosomes are found either on the cytosol, or on the endoplasmic reticulum.

Cytoplasm Cytoplasm is the fluid substance that fills the space between the cell membrane and the cellular organelles. The cytoplasm consists of all of the contents outside of the nucleus and enclosed within the cell membrane of a cell. This includes the cytosol and in eukaryotic cells, organelles such as mitochondria and ribosomes. The cytoplasm is clear in color and has a gel-like appearance. The cytoplasm helps to move materials around the cell and also dissolves cell waste.

Golgi apparatus The Golgi apparatus gathers simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them in vesicles, and either stores them for later use or sends them out of the cell.

Cell nucleus The nucleus is at the center of the cell The nucleus contains the DNA, the genetic material of the cell. The DNA contains the information necessary for constructing the cell and directing the multitude of synthesis tasks performed by the cell in the process of life and reproduction.

Mitochondria Info The power house of the cell. Where the biochemical processes of respiration and energy production occur. It has a double membrane, and the inner layer is folded into more inner layers. An organelle found anywhere in the cell. There is always an abundancy of them.

Peroxisome Structure and Location Peroxisomes are spherical organelles in the cell’s cytoplasm Function Peroxisomes breakdown long chain fatty acids The long fatty acids are converted to medium chain fatty acids They are then sent to the mitochondria where they are broken down to carbon dioxide and water

Cell Membrane Maddie Roberts 4th Function: The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins. Location: Surrounds the cytoplasm of the cell Jobs of the cell membrane: •Isolate the cytoplasm from the external environment •Regulate the exchange of substances •Communicate with other cells •Identification

Nucleus A membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. It is the command center and most prominent organelle in the cell. Usually located in the center of the cell.

Microvilli Structure- Hair like folds Location- On Plasma membrane Function- Increases cells size, good for absorption and secretion functions.

Nuclear Membrane! By: Natalie Foster What is a Nuclear Membrane and what is its location? It is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. What is its function? The nuclear membrane keeps DNA inside the nucleus and protects it from materials in the cytoplasm. Nuclear Membrane! What is its structure ? outer membrane of the nuclear envelope is dotted with ribosomes. Attached to the nucleoplasm side of the inner membrane is a sheet-like structure of protein filaments By: Natalie Foster

Nucleolus •The nucleolus has many functions such as assembly of signal recognition particles, modification of transfer RNAs and sensing cellular stress. It takes up 25% of volume in the nucleus and is the largest structure in the nucleus. The nucleolus disassembles at the beginning of mitosis and begins to reassemble in telophase. The nucleolus assembles ribosomes. Made up of proteins and RNA.

Smooth and Rough Endoplasmic Reticulum Location – The Rough Endoplasmic Reticulum surrounds the nucleus with the smooth ER just outside of that. Functions include the folding of protein molecules into sacs and is also responsible for the transportation of synthesized proteins. These proteins are then sent to the Golgi Apparatus.

Vacuole Vacuoles are storage bubbles found in cells -a membrane bound sac They are in both plant and animal cells but are much bigger in plant cells. Vacuoles store food or any kind of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination. Animal Cell Plant Cell

Nuclear Membrane(nuclear envelope) What is it? -A double lipid bilayer membrane which surrounds the genetic material and nucleolus in the cell -Consists of two layers—the inner nuclear membrane, and the outer nuclear membrane. What does it do? -Keeps the DNA inside the nucleus and protects it from materials in the cytoplasm.

Usually attached to the cell wall on the outside of the cell. Flagella Main role is locomotion and has a secondary function as a sensory organelle. Usually attached to the cell wall on the outside of the cell. They are filamentous proteins attached to the cell surface to provide the swimming movement for most motile procaryotes.

Cytoskeleton Function: Provides structure and organization throughout the cell Enables cell to preform basic functions like divide and move Structure: Made up of three types of protein filaments Actin filaments Intermediate filaments Microtubules Location: Everywhere throughout a eukaryotic cell

Chromosomes •Chromosomes are threadlike structures and can be found inside a cells nucleus. •They are made of protein and DNA.

Chromosome Function They carry all the info needed to help a cell grow and reproduce They are made up of DNA, which are your cells

Centrioles The function of centrioles is to aid in the division of cells. The centrioles are usually located near the nucleus. The structure of centrioles is a ring of 9 groups of fused micro-tubes. Jenny Gallagher, 4th Period Centrioles The function of centrioles is to aid in the division of cells. The centrioles are usually located near the nucleus.

 Cilia   Cilia are slender, microscopic, hair-like structures or organelles that extend from the surface of nearly all animal cells. There are two types of cilia: motile cilia and non-motile, or primary cilia, which typically serve as sensory organelles. Cilia move liquid past the surface of the cell. For single cells, such as sperm, this enables them to swim. Some serve as like antenna that receive sensory information for the cell, processing signals from the other cells or the fluids surrounding it.

Vacuole They are located in the cytoplasm. Their function is to store food or any variety of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination. Eventually, those waste products would be sent out of the cell.

Centrosome By: Jamarius Dozier Structure/ Location- Consists of 2 centrioles. Microtubule Function- Microtubule Organizing Center. Plays role in Mitosis and cytokenisis
