What organelle of the cell regulates all of the cell’s activities?
Nucleus
Cells vary in what?
Size, function, and shape
A membrane that allows only certain molecules to pass through it is called what?
Semipermeable membrane
What is the cell theory?
All cells come from other cells.
Cells are the smallest unit of life.
All organisms are made of at least one cell.
What part of a plant cell is used to capture light energy which it will use to make it’s food?
Chloroplast
Bacteria cells are different from animal cells because bacteria cells do not have what?
Membrane bound organelles
The part of the plant cell that makes the plant cell more rigid than an animal cell is called what?
Cell wall
The endoplasmic reticulum in a cell does what?
Transport substances
The liquid, jelly-like portion of the cell is called what?
Cytoplasm
What is the function of the ribosome?
To make proteins
What is the smallest unit that can carry on all of the processes of life?
A cell
Animal cells are prokaryotic or eukaryotic?
Eukaryotic
Remember: YOU are an animal. YOU have EUkaryotic cells.
Which structure directly controls the transport of materials in and out of a cell?
Cell membrane
Which structures are found in plant cells, but not in animal cells?
Chloroplast
Cell wall
Vacuoles
Which organelle is the site of protein synthesis?
Ribosome
What does the term hydrophillic mean?
Water loving
The cell membrane consists of what and what?
Proteins and lipids
What is exocytosis?
The cell “spitting” out large objects
Describe a eukaryotic cell.
They have membrane bound organelles
Who invented the microscope?
Robert Hooke
Organisms that have more than one cell are called what?
Multicellular
What is the name of the organelle that forms spindle fibers during mitosis and is found only in animal cells?
Centriole
Proteins synthesized by the ribosomes attache to the rough ER are for inside or outside the cell?
Outside
What kind of cells do not have a cell wall?
Animal cells
In what solution does water move into the cell?
Hypotonic
What happens to water when a cell is placed into a strong sugar solution?
It leaves the cell
What happens to the relationship between the surface area and the volume as a cell grows?
The volume grows faster than the surface area.
What is the difference between prokaryotic and eukaryotic?
Prokaryotic don’t have membrane bound organelles (Bacteria)
Eukaryotic have membrane bound organelles. (Regular cells)
What is gravity?
The attraction between two objects.
