Organelles pt 1
The "powerhouse" of the cell, this organelle is where cellular respiration occurs to produce ATP.
What are mitochondria?
The main component of the cell membrane is arranged in a double layer.
phospholipid
He observed cork under a microscope and was the first to use the term "cell."
Robert Hooke
This type of microscope uses light and a series of lenses to magnify objects.
light microscope
This organelle modifies, sorts, and packages proteins and lipids for storage or release from the cell.
golgi bodies
This small, dense organelle is the site of protein synthesis.
Ribosome
The movement of particles from an area of high concentration to an area of low concentration.
diffusion
A Dutch merchant who observed tiny living organisms in pond water and called them "animalcules."
Anton van Leeuwenhoek
This type of microscope uses a beam of electrons to magnify images.
electron microscope
A jelly-like substance that fills the cell and holds the organelles in place.
cytoplasm
Found in plant cells, this large, central sac stores water, nutrients, and waste.
vacuole
This type of transport requires energy to move substances across the membrane against their concentration gradient.
active transport
A German botanist who concluded that all plants are made of cells.
Matthias Schleiden
What is the total magnification of a microscope with an ocular lens magnification of 10x and an objective lens magnification of 50x
500x
The "control center" of the cell, it contains the cell's genetic material.
nucleus
A network of protein filaments that provides a cell with its shape and internal organization.
cytoskeleton
The diffusion of water across a selectively permeable membrane.
osmosis
A German zoologist who concluded that all animals are made of cells.
Theodor Schwann
What is the typical maximum magnification of a compound light microscope?
1000x
organelles are involved in the synthesis of lipids and proteins; one has ribosomes on its surface.
endoplasmic reticulum
A rigid structure outside the cell membrane in plant cells that provides support and protection.
cell wall
The process of taking material into the cell by means of infoldings or pockets of the cell membrane.
endocytosis
A German physician who concluded that new cells can only be produced from the division of existing cells.
Rudolf Virchow
A major disadvantage of electron microscopes is that they can only be used to examine these types of specimens.
non living specimen
Found in animal cells, this organelle contains digestive enzymes that break down lipids, carbohydrates, and proteins.
lysosome
