Cell Biology Flashcards
(25 cards)
What are the building blocks of life?
Cells
What do prokaryotes NOT have?
No nucleus, no membrane-bound organelles
What controls what goes in and out of the cell?
Cell Membrane
What surrounds both an animal and plant cell?
Cell Membrane
Where are other organelles suspended?
Cytoplasm
Describe what cytoplasm looks like.
A gel like liquid made mostly of water
Where do chemical reactions needed for life happen?
Cytoplasm
What is the smallest organelle?
Ribosomes
Where are proteins made in a cell?
Ribosomes
What controls all activities of the cell and contains DNA?
Nucleus
What is the “highway of the cell”?
Endoplasmic Reticulum (ER)
What are the two kinds of ER?
Rough ER and Smooth ER
What is the difference between Rough ER and Smooth ER?
Rough ER is covered in ribosomes and used for making proteins; Smooth ER has no ribosomes and is used in the production of fats and oils
Where does respiration happen?
Mitochondria
What is the “Powerplant” of the cell?
Mitochondria
Where is chemical energy in sugar converted to useable energy? (i.e. cellular respiration)
Mitochondria
What organelle breaks down invading bacteria and damaged parts of the cell?
Lysosomes
What are the “cleaners” of the cell?
Lysosomes
What type of cell are fungi, animals, protists, and plants?
Eukaryotes
What organelle does photosynthesis happen in?
Chloroplasts
What does chlorophyll do?
Converts energy from the sun into usable chemical energy in the form of sugar
What organelle contains cell sap, mostly water?
Vacuole
What organelle stores and transports nutrients, waste, and other substances in the cell?
Vacuole
What provides rigid support for the cell and is made of cellulose in plants?
Cell Wall
