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.

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

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

Animal Cell Ribosome (attached) Nucleolus Ribosome (free) Nucleus Cell Membrane Nuclear envelope Mitochondrion Smooth endoplasmic reticulum Rough endoplasmic reticulum Centrioles Golgi apparatus copyright cmassengale

Animal Cell Eukaryotic cells, round/irregular shape Producing hormones and enzymes to providing energy for animal cells Centrioles Cilia Flagella

Plant Cell copyright cmassengale

Plant Cell Eukaryotic cells , a rectangle shape Undergo photosynthesis Their distinctive features include: A large central vacuole Cell Wall Chloroplast
