Cell Organelle
Peyton Harris & Khanysha Peebles s'more
Plasma or Cell membrane
The plasma membrane is the boundary between the cell and its environment. It regulates what enters and exits the cell. Cell membranes keep the pieces inside. The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container.
Cell Wall
Cell walls are made of cellulose. They provide protection for a plant cell to survive. Cell walls are more likely to be found in plants. However, a cell wall is not present in animal cells.
Cytoplasm
Cytoplasm is the jelly-like liquid that fills a cell. This liquid is made up mostly of water and salt and is present within the cell membrane of all cell types and contains all organelles and cell parts. Cytoplasm is found in both animal and plant cells.
Nucleus
Enclosed membrane organelle found in the center. This controls everything in the cell (growth ect). This is found in all cells.
Nuclear Membrane
(A.k.a the nuclear envelope) is the double lipid bilayer membrane which surrounds the genetic material and nucleolus.
Nucleolus
The nucleolus is inside the nucleus. It is made of RNA and DNA but does not contain much DNA at all.
Centrioles
Centrioles are found in animal cells. They are there to help the cell when it divides. They are put to work in the processes mitoses and meiosis. They are usually located near the nucleus. Centrioles are found in both animal and plant cells.
Ribosomes
Ribosomes are protein builders of the cell. They are found in both animal and plant cells.
Golgi Apparatus
The Golgi Apparatus gathers simple molecules and combines them to make molecules that are more complex. This is the organelle that builds lysosomes. It is easy for me to identify the Golgi Apparatus because it looks like stacks of pancakes. The Golgi Apparatus is found in both animal and plant cells.
Endoplasmic Reticulum
The Endoplasmic Reticulum is membranes found throughout the cell and connected to the nucleus. It is found in animal and plant cells. There are rough and smooth endoplasmic reticulums' ; they have the same type of membranes but different shapes.
Mitochondria
Organelles that act like a digestive system. Mitochondria are made of two membranes; outer membranes and inner membranes. The outer membrane covers the organelle like skin. The inner membrane folds over many times and creates layered structures called cristae. A fluid called the matrix is also present in mitochondria. Mitochondria is found in animal and plant cells.
Chloroplast
Chloroplasts are food producers of a cell. They are only found in plant cells. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
Lysosomes
Lysosomes hold enzymes that were created by the cell. The purpose of the lysosomes is to digest things. These are found mainly in animal cells.
Peroxisomes
They are small vesicles found around the cell that absorbs nutrients the cell has received. They have a single membrane that contains digestive enzymes for breaking down toxic materials in the cell. They are known for digesting fatty acids. Peroxisomes are found in both animal and plant cells.
Vacuole
Vacuoles are storage bubbles found in cellls. They store food or any variety of nutrients a cell might need to survive. They are found in both animal and plant cells but are larger in plant cells. There is a membrane that surrounds a mass of fluid in a vacuole.
Cytoskeleton
The cytoskeleton provides structure. The cytoskeleton is present it animal and plant cells.
Chromatin
Chromatin is a combination of proteins and DNA that make up the contents of the cells' nucleus. It is found in animal and plant cells.
