PROTISTS AND BACTERIA

PROTISTS

• Protists can reproduce asexually or sexually
• Some protists, like spirogyra, are haploid protists
• Haploid protists reproduce through binary fission
• In stressful environments, protists can make spores
• If spores of two protists are brought in close proximity, they can reproduce

PROTISTS

• Also reproduce through budding
• A small piece grows off the original protist
• The piece breaks off and grows into an identical copy of the protist
• A form of asexual reproduction

BACTERIA

• Divide mainly through binary fission (asexual)
• In binary fission, the bacteria splits into two identical daughter cells
• This can happen every twenty minutes
• Genetic variation occurs when they grab stray pieces of DNA from their environment
• Genetic variation can also happen with plasmid transfer

COMPARISON/CONTRAST

• Both can reproduce asexually, through binary fission
• Protists can also reproduce using spores sexually
• Bacteria can only reproduce asexually
• Protists have complex lifestyles, while bacteria have fairly simple ones
