The Cell Introduction

Cell - The Organelles Cells are the basic unit of life. Cells are the smallest unit of life that can replicate independently, and are often called the "building blocks of life". Organelles or “little organs” are small, specialized cellular subunits in a cell. Organelles help a cell to move molecules, create and store energy, store information and perform many other functions.
3
Prokaryotic Cell First and simplest cell type
Bacteria Does not have a true nucleus and lacks membrane-bound organelles. Surrounded by cell membrane & cell wall Contain ribosomes in their cytoplasm to make proteins
4
Eukaryotic Cell Cells that have a nucleus and membrane-bound organelles Two types of cells Plants and animals More complex type of cells Contain 3 basic cell structures: Nucleus Cell Membrane Cytoplasm with organelles
5
Animal Cell Ribosome (attached) Nucleolus Ribosome (free) Nucleus
Cell Membrane Nuclear envelope Mitochondrion Smooth endoplasmic reticulum Rough endoplasmic reticulum Centrioles Golgi apparatus copyright cmassengale
6
Animal Cell Eukaryotic cells, round/irregular shape
Producing hormones and enzymes to providing energy for animal cells Centrioles Cilia Flagella
7
Plant Cell copyright cmassengale
8
Plant Cell Eukaryotic cells , a rectangle shape Undergo photosynthesis
Their distinctive features include: A large central vacuole Cell Wall Chloroplast
9
Organelles Activity Complete the following Prokaryotic vs. Eukaryotic Foldable in your notebook.
