Cell Test Flashcards
What characteristics do prokaryotes and eukaryotes share?
DNA, cell membrane, cytoplasm, and ribosomes.
What characteristics do prokaryotes have
Always unicellular, no nucleus with free-floating DNA, no organelles except ribosomes, bacteria only, eubacteria and archaebacteria
What characteristics do eukaryotes have?
Can have a cell wall, includes plants, animals, protists, and fungi, has organelles, has nucleus with DNA enclosed inside
Bacteria have ______ cells while animal cells have _______ cells.
Prokaryotic
Eukaryotic
What structures do plant cells have the animal cells do not have?
Cell wall, chloroplast
Which part of a cell is larger in the plant cell than in an animal cell.
Vacuole
What is the function of the lysosome?
The lysosome contains digestive enzymes
What are the characteristics of all living things?
Cells, reproduce, DNA, respond/react, energy, growth
What is the function of the nucleus?
The nucleus directs cells activity
What is the function of the nuclear membrane?
Directs what can enter and exit the nucleus
What is the function of the ribosomes?
Makes proteins
What are all three parts of the cell theory?
All cells come from other cells, cells are the basic unit of structure and organization in an organism, all living things are made up of cells.
What is active transport?
When a cell moves from low to high concentration and does use energy.
What are the types of active transport?
Endocytosis and exocytosis
What is passive transport?
Passive transport is when a cell moves from a high to low concentration and does not use energy
What are the types of passive transport
Osmosis and diffusion.
What part of the cell is responsible for endocytosis and exocytosis?
The cell membrane
Pure water passes through a cell membrane through the process of
Osmosis
What should happen is the concentration of water in the cell cytoplasm is higher than the concentration of water outside of the cell?
The water will then move out to the area of lower concentration outside of the cell to balance it.
What is the name of the process where food and oxygen produce energy?
Cellular respiration
What is the formula for cellular respiration
C6h12o6+ 6o2 6h2o+co2 + ATP
Which organelle is responsible for Cellular respiration
Chloroplast
What is the name of the process responsible for making food in plants
Photosynthesis
What is the formula for photosynthesis
6co2+6h2o+light c6h12o6+6o2
Which organelle is responsible for photosynthesis?
Chloroplasts
What three reasons the cell division occurs in cells of multicellular organisms?
Replacement, repair, growth.
Cell membrane
Protects the cell from its surroundings
Egg shell
Cytoplasm
Fills the space between the cells organelle providing them support and protection.
Jello
Ribosome
Makes proteins that are the building blocks to create organelles make repairs and send messages
Factory worker
Mitochondria
Powerhouse of the cell. Produces energy from sugar through a process called cellular respiration
Electricity
Chloroplast
Found in plant cells and contains chlorophyll. This is where photosynthesis takes place
Food
Lysosome
Digests excess or worn-out organelles food particles and viruses and bacteria. Disposal of the cell.
Trash truck
Vacuole
Helps plants maintain shape stores water and helps with digestion and waste removal.
Sponge
Nucleus
Direct cells activity
President
Nucleolus
Makes ribosomes
Assembly line
Golgi body
Packages proteins and lipids to be transported out of the cell.
Envelope
Endoplasmic reticulum
Transports proteins
Taxi
