Cell Functions
One major defining feature of a eukaryotic cell is that they contain _____________
What is a nucleus
What organelle is the brains of the cell?
What is the nucleus
The variable in an experiment that is CHANGED or is MANIPULATED.
What is an independent variable
The function of the central vacuole in plants is to store ______.
What is water
What organelle holds everything in place?
What is the cytoplasm
What organelle gathers sunlight needed for photosynthesis to occur?
What is the Chloroplast
A solution whereby water concentration is the same inside and outside the cell membrane
What is isotonic solution
Cells produce ________, which are packaged and sent all throughout the cell.
What is proteins
This organelle is responsible for getting rid of waste products in the cell
What is Lysosomes
The process in which radiant energy is transformed into glucose and water
What is photosynthesis
The movement of water across a semi-permeable membrane is called?
What is osmosis
This organelle is a continuous membrane system that forms a series of flattened sacs, outside of the nucleus
What is the Endoplasmic Reticulum
The part of the experiment that DOES NOT change
control/contstant
What type of transport across a membrane goes against the gradient?
What is active transport
Organelle that packages proteins into membrane-bound vesicles
What is the Golgi Body
What is the dependent variable
a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the production of protein
DNA
a small dense spherical structure in the nucleus of a cell that produces ribosomes
Nucleolus
What types of cells have a structural layer surrounding them, just outside the cell membrane. It can be tough, flexible, and sometimes rigid
Plant
Often referred to as the power plant of the cell
What is the mitochondria
Cells use the plasma membrane to engulf(capture) large materials
Endocytosis
This is the body's way of maintaining balance to ensure it can function and survive.
Homeostasis
infectious agent of small size and simple composition that can multiply only in living cells of animals, plants, or bacteria
Virus
These cells have circular DNA
Prokaryotic
What is the border that surrounds the cells cytoplasm?
What is the plasma membrane
Transportation of molecules that move from high concentration to low concentration
Passive transport
This theory suggests that mitochondria and plastids in eukaryotic cells were once independent prokaryotic cells engulfed by the larger, eukaryotic cells
Endosymbionic Theory (Endosymbiosis)
a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence
Cytoskeleton
This type of RNA brings the needed amino acids to the ribosomes to be strung together to form a specific protein
tRNA (transfer RNA)
Which organelle manufactures protein by assembling sequences of amino acids?
What is a ribosome
A means of cell locomotion. The sperm cell is the only cell in humans that have this and use for locomotion.
Flagella
