sphere-shaped particle composed of protein and ribonucleic acid (RNA) that serves as the site of protein synthesis
ribosomes
What is this?
ribosomes
What is the function of vesicles?
movement of materials in, out, and inside of the cell
Why do cells have organelles?
Organelles serve specific functions to keep a cell alive.
The gel-like fluid that fills over 50% of the cell; where chemical reactions happen within the cell.
cytoplasm
single-celled organisms that have no defined nucleus (ex: bacteria and archaea)
prokaryote
The organelle found in plant cells and most algae where photosynthesis occurs; houses chlorophyll
chloroplast
The organelles responsible for clean up and keeping the cell free of unwanted waste
lysosomes
What is the main difference between prokaryotic cells and eukaryotic cells?
Pro= No nucleus; Eu= NUcleus, so eukaryotes have a nucleus with DNA inside
also called plasma membrane, thin membrane that surrounds every living cell
cell membrane
A cell is a eukaryote if it has a?
nucleus
What is the function of cell wall?
to provide structure and protection for a plant cell
What are these?
organelles
a network or system of flattened sacks that are responsible for the production of proteins. (smooth or rough)
endoplasmic reticulum
_______ is how the cell gets its energy to live. (powerhouse of the cell)
mitochondria
Name one component of the modern cell theory.
All living things are made of cells. Cells are created from existing cells. Cells are the smallest living thing. DNA is passed from cell to cell.
What is the function of the vacuole?
holds various solutions or materials
any cell or organism that possesses a clearly defined nucleus.
eukaryote
A group of membranes within the cytoplasm that package up substances that the cell creates and needs to get rid of.
Golgi Body
The part of the cell responsible for the structure and framework of the cell
cytoskeleton
the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body, the building blocks of all living things.
cells
Who discovered cells?
Robert Hooke
cylinder shaped organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
centriole
