Science Flashcards
What is the thin covering that forms the outer boundary of the cell?
Cell membrane
What is the central molecules that can pass through a membrane but others can not
Selectively permeable membrane
What is movement of substances, through a membrane without the use of the cells own energy
Passive transport
What is the movement of molecules from a place of higher concentration to a place of lower concentration
Diffusion
What is the diffusion of water through a selective permeable membrane?
Osmosis
What requires the cell to use its own energy to transport substance through a membrane?
Active transport
What supports the protection of the cell
cell wall
What is a thick fluid
fluid that contains many small organelles
Cytoplasm
What is parts of a cell that performs many of the functions needed to keep the cell alive
Organelle
What is the cells powerhouse, produces usable energy for the cell
Mitochondria
What is the cells delivery system, allows for transport within a cell
endoplasmic reticulum
What makes proteins?
Ribosme
What is the processes substance for use inside the cell or to be released?
Golgi apparatus
What is the sells storage container, stores, food, water, wastes, and chemicals
Vacuole
What is the cells garbage disposal, disposes of unneeded cellular structures or harmful substances?
Lysosomes
And what is found in a plant cell, captures the suns energy and uses it to make sugar
Chloroplast
What has many short hair like proteins, moves the cell or substance around the cell
Cilium
Oh, what has a few long hair like proteins, moves the cell or substance around the cell
Flagellum
What is a roundish structure that functions as the control center for the cell
Nucleus
Most organisms are made of these cells, have a true nucleus, and contain most or all organelles
eukaryotic
What has no true nuclear us only only a nuclear area and no organelles that are surrounded by a membrane
Prokaryotic
What are the parts of a cell that are so dependent on each other that if just one part does not work right, the entire cell may not function properly
Irreducible complexity
