Cells & Tissues

Functions:

• The cell wall gives external protection to the cell, keeps the cell from evaporating because of the heat. Plus the cell wall manages the cell’s waste matter.
• The cell (plasma) membrane controls the substance in and out the cell.
• The Golgi Apparatus gathers simple molecules to make macro-molecules like proteins and lipids as they are synthesized within the cell.
• The Golgi Vesicles is all what is packaged from The Golgi Apparatus. And then The Golgi Vesicles can travel to other cells.
• The Nucleolus can be thought of as the “brain of the nucleolus”. the nucleolus’ main function is to rewrite ribosomal RNA (rRNA) and combine it with proteins.
• The Nucleus is the “brain of the cell” and it contains DNA. The Nucleus contains most of the genetic material of the cell.
• The Ribosomes make proteins which are necessary repairing damage or directing chemical processes of a cell.
• The endoplasmic reticulum (smooth and rough ER) folds protein molecules in sacs called cisternae and the transports the synthesized proteins in vesicles to the Golgi apparatus.
• The Microtubules move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins.
• The Mitochondrion take in nutrients, break them down, and create energy rich molecules for the cell.
• The Cytoplasm is responsible for giving a cell its shape.
• The Centrioles help the cell to divide.
• The Lysosomes are in charge of digestion and waste removal.
• A pinocytotic vesicle aids in transportation as a cell’s plasma membrane absorbs molecules from outside.
• The Amyloplast transform glucose into starch through the process of polymerization, and store starch grains within their stretched membranes.
• The Chloroplast converts the sun light energy to be used as useful sugar in the plant cell.
• The Vacuole Membranes are storage bubbles.
• The Raphide Crystal repels animals away from plants.
• The Druse Crystal helps to protect the plant.

1. Plant Cells contain a cell wall to further protect the cell, Animal Cells do not~
2. Plant Cell contain chloroplasts to absorb light energy and turn it into food, Animal Cells do not
3. Animal Cells contain centriole for reproductive purposes, Plant Cells do not.

The cell is the smallest structural, functional and biological unit of all organisms.
The tissue is a group of cells from the same origin that have a specific function.
An organ is a group of tissues in a living organism that have been adapted to perform a specific function.
An organ system is a group of organs that work together to preform functions.
