The Cell Flashcards
(21 cards)
Organelle
Specialized structure that performs important cellular functions within eukaryotic cell
Ex. Makes up a cell
Noah
Brennen
Cell membrane
Thin flexible barrier around a cell regulates what enters and leaves the cell
Ex.
Cell wall
Strong supporting layer around the cell membrane in plants algae and some bacteria
Ex.only in plants
Chloroplasts
Organelle found in cells of plants
Ex. Photosynthesis
Chlorophyll
Principal pigment of plants and other photosynthetic organisms
Ex. What makes the plant green and captures light
Cytoplasm
Material inside the cell membrane not including the nucleus
Ex. Kind of gel that makes up most of cell
Mitochondria
Cell organelle that converts the chemical energy into something more useful for a cell
Ex.metabolism
Nucleus
Contains DNA and controls cells activities
Ex.command center
DNA
Genetic material
Ribosome
Proteins are assembled
Ex.made of RNA
Vacuole
Storage
Ex.stores food waste and water
Eukaryotic
Contains a nucleus
Prokaryotic
No nucleus
Ex. Bacteria
Cell specialization
The process in which cells develop in different ways to perform different tasks
Diffusion
Process by which molecules tend to move from an area of high to low concentration
Ex. The salt water make the onion skin shriveled up
Osmosis
Diffusion of water through a selectively permeable membrane
Ex.water rehydrating the onion cell
Antigen
Protein marker on cell membrane
Ex.
Cellular respiration
Energy releasing process
ATP
Usable but unstable form of energy
Active transport
Photosynthesis
Biochemical food making process
Ex. Plants produce oxygen with this
