Cell

All living things are made up of cells, some are only made up of one cell and others of many cells.

There are 2 types of organisms based on how many cells they have; unicellular, and multicellular

Definition:

Cells are the building blocks of life and they are the most basic structural and functional units of our life. They form the tissues, organs, and organ systems in organism’s

If the average adult human has around 37.2 trillion cells

Cells are called the building blocks of life because they are the basic structural and functional units of an organism.

Robert Hooke named the cells after tiny boxes that monks lived in, after he cut thin slices from cork and looked at them under a microscope. They were named cells in the year 1665

Animal Cells

Nucleus

Nucleus

  • Carries the genes

  • Regulates cell’s activity

Nucleolus

  • Constructs ribosomes

Golgi Apparatus

  • Arranges important protein to the destination

Ribosomes

  • Constructs protein from amino acids

Rough Endoplasmic Reticulum

  • Attached to ribosomes

  • Produces protein needed for the cell to function

Smooth Endoplasmic Reticulum

  • No ribosomes attached

  • Makes lipids in the cell

  • Helps detoxify harmful substances found in cell

Mitochondria

  • Cells powerhouse

  • Produces energy

Lysosome

  • Breaks down large molecules

Centriole

  • Helps cell division

Cytoplasm

  • Holding all the organelles together

  • Protects organelle from damage

Cell Membrane

  • Protecting the cell

  • Regulates transport of materials (enter/exit)

Plant Cells

Cell Wall

  • Provide structural strength and support

  • Prevents osmotic bursting
