Unit 1: Key Concepts in Biology Flashcards
What structures are found in both animal and plant cells?
Nucleus, cytoplasm, cell membrane, mitochondria, and ribosomes.
What additional structures are found in plant cells but not in animal cells?
Cell wall, chloroplasts, and permanent vacuole.
How do bacterial cells differ from animal and plant cells?
Bacterial cells are prokaryotic, lack a nucleus, and have DNA in a loop or plasmids.
What is the function of mitochondria?
To produce energy through aerobic respiration.
What is the role of ribosomes?
To synthesize proteins.
How do light microscopes and electron microscopes differ?
Light microscopes have lower magnification and resolution than electron microscopes.
What is the function of the chloroplast in plant cells?
To carry out photosynthesis.
What is the cell wall in plant cells made of?
Cellulose.
What is the role of the flagella in some bacterial cells?
To aid movement.
Why are electron microscopes useful for studying cells?
They provide high-resolution images, allowing visualization of organelles like ribosomes.
