Types of cells and Cell Structure
Types of cells
Eukaryotic (complex) - animal, plant, fungi and protist cells.
Prokaryotic (simple, cell itself on its own) - bacteria cells
Cells are the smallest unit of life that can replicate independently. There are many variations of cells
Animal and Plant Cells
Animal
cell membrane
nucleus
Cytoplasm
Mitochondria
Ribosomes
Plant
cell membrane
nucleus
Cytoplasm
Mitochiondria
Ribosomes
Cell wall
Permanent Vacuole
Chloroplasts
Sub-cellular Structures (organelles)
Cell Membrane = control which substances enter and leave the cell
Nucleus = contains genetic material (DNA)
Cytoplasm = where the chemical reactions take place
Mitochondria = the powerhouse of the cell, contains energy (cellular respiration)
Ribosomes = where proteins are made
Cell Wall (plant cells only)= made of cellulose, provides support and structure to the cell
Permanent Vacuole (plant cells only) = contains cell sap (sugars and salts)
Chloroplasts (plant cells only) = where photosynthesis takes place, contain chloroform (substance that makes plants green
Plasmids (prokaryotes only) = extra genes (antibiotic resistant)
Flagella (prokaryotes only) = propel the bacteria
Prokaryotes
bacterial cells = unicellular (one cell)
contains cell membrane, ribosomes, cytoplasm and cell wall, plasmids, flagella
Don't have mitochondria or chloroplasts. Their DNA aren't kept inside the nucleus. Instead, they have a circular strand of DNA that floats around in the cytoplasm. The circular strand of DNA contains all the genes they need to survive and reproduce.
