biology Flashcards
(23 cards)
cells
the smallest unit of life
organelles
specialized subunits of a cell that have a specific jobs
prokaryotes
cell thath do not have a nucules
eukayotes
cells taht do have a niuciules
cytopsla
the fulid inside the cell membrain that contails all organells
pili
tiny hairs on prokaryotes that help move and reprouce
ribisome
round structure where protiens are made
flageumm
tail - like strutucre that aid on mobilkty
nucleaus
contains genetic materialof cells
nucleoues
Structure inside the nucleus that manufactures ribosomes, the cell’s protein-producing structures.
Nuclear Envelope:
Double-layered membrane that encloses the contents of the nucleus during most of the cell’s life cycle.
Nuclear Pores:
Small holes within the nuclear envelope that regulate the passage of molecules between the nucleus and cytoplasm
Endoplasmic Reticulum:
A transport system that extends from the nucleus and Moves materials around the cell. (Can be smooth or rough depending on if it contains ribosomes.)
Smooth ER:
Contains no ribosomes and helps detoxify the cell and create lipids.
Rough ER:
Studded with ribosomes…aid in protein production and transport
Golgi Apparatus:
Does not make anything but prepare materials for shipment outside the cell by packaging them into vesicles
Vacuoles:
Single membranes that form around solid or liquid contents and holds materials until needed later.
Vacuoles
Single membranes that form around solid or liquid contents and holds materials until needed later.
Lysosomes:
Produce chemicals that digests wastes and worn-out cell parts.
Chloroplasts.
Organelles found in plant cells that use energy from the sun to make food.
Mitochondria:
“Powerhouse of the cell” that supplies energy to power all of the cell’s functions.
Cell Wall:
Surrounding structure that adds support and protection for plant cells only.
Cell Membrane:
Maintains the cell’s limits or boundaries in both plant and animal cells by controlling what goes into and out of the cell.
