Cell Organelles

By: Anani Reed

Cell Membrane

Structure: Not a solid structure. Made of millions of smaller molecules. Proteins and Phospholids make up the cell membrane.

Function: To hold all the pieces in the cell together

Exists in: Both

Cell Wall

Structure: Made of specialized sugars called cellulose.

Function: Helps a plant cell keep it's shape and provides protection.

Exists in: Plant Cells

Cytoplasm

Structure: Has many different molecules dissolved together such as enzymes, fatty acids, sugars and amino acids.

Function: holds the internal components in place

Exists in: both

Nucleus

Structure: Big dark spot in the center of the cytoplasm

Function: Serves as a brain to cells, controlling the eating, movement and reproduction.

Exists in: Both

Nuclear Membrane

Structure: double layered membrane outside the nucleus

Function: separates the fluid inside the nucleus from the fluid outside the nucleus

Exists in: Both

Nucleolus

Structure: round body located inside the nucleus. Made of RNA and protein.

Function: Makes ribosomal RNA and plays a role and making proteins in the cell

Exists in: Both

Big image

Centrioles

Structure: Located near the nucleus. Have a cylindrical shape.

Function: Helps the cell when it's time for the cell to divide.

Exists in: Animal

Chromatin

Structure: Made of DNA, RNA and nuclear proteins. Located in the nucleus.

Function: Plays a part in cell division and uses to DNA and RNA to see chromosomes

Exists in: Both

RIbosomes

Structure: Float free in the cytoplasm (cytosol). Found in both prokaryotes and Eukaryotes.

Functions: Protein builder of a cell

Exists in: Both

Golgi Apparatus

Structure: Works closely with the Endoplasmic Reticulum. Found in most cells. Shaped like Pancakes.

Function: Modifies, sorts and packages macromolecules. Modifies proteins delivered from the rough ER and also transports lipids around the cell.

Exists in: Both

Endoplasmic Reticulum (ER)

Structure: Two types of ER, Smooth and Rough. Rough ER is called rough because it has ribosomes attached. The smooth ER looks like tubes.

Function: Used as a manufacturing and packaging system. Smooth ER works to store and create lipids and steroids. Rough ER work in packing proteins.

Exists in: Both

Mitochondria

Structure: Small organelles floating free throughout the cell. Consists of two membranes. They can grow large or be combined with other mitochondria.

Function: Takes nutrients, breaks them down and creates energy rich molecules. "The powerhouse cell"

Exists in: both

Chloroplast

Structure: Double layered membranes, the site of photosynthesis

Function: Converts light energy from the sun into sugars to be used for food.

Exists in: Plants

Big image

Lysosome

Structure: Contain acid enzymes that break down waste materials and cellular debris.

Function: Hold enzymes produced by the cell. Digests excess materials.

Exists in: Animal

Peroxisomes

Structure: Small vesicles found around a cell. They are a single layered membrane organelle.

Function: Absorbs nutrients and digests fatty acids.

Exists in: Both

Vacuole

Structure: Fluid-Filled Sacs

Function: stores food, water and waste

Exists in: Both

Cytoskeleton

Structure: Contains microfilaments, intermediate filaments and microtubules.

Function: Helps with a cells shape, support and movement.

Exists in: Both
