1-2 Eukaryotic Cells Flashcards
a rigid structure that surrounds the cell membrane and provides support to the cell
cell wall
a complex sugar that most animals can’t digest
cellulose
a protective barrier that encloses a cell
cell membrane
a group of compounds that do not dissolve (includes fats and cholesterol); move materials in and out of the cell
Lipids
a lipid that contains phosphorus;
phospholipid
“water loving”; form outer part of membrane
hydrophilic
a web of proteins in the cytoplasm
cytoskeleton
a large organelle in a eukaryotic cells; contains the DNA
nucleus
where a cell begins to make its ribosomes
nucleolus
cell organelle composed of RNA and protein; the site of protein synthesis
ribosome
any one of about 20 different organic molecules that are used to make proteins
amino acid
a system of folded membranes that is found in a cell’s cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids
endoplasmic reticulum
in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration; breaks down sugar to make energy
mitochondrion
where the energy from the mitochondrion is stored (adenosine triphosphate)
ATP
organelles in plant and algae cells in which photosynthesis takes place
chloroplasts
