Chapter 5 Keywords Flashcards
A membrane network within the cytoplasm of cells involved in the synthesis, modification, and transport of cellular proteins
endoplasmic reticulum
Small hair like structures similar to flagella, that line the surfaces of certain cells and beat in rhythmic waves, providing locomotion
cilia
The internal framework of a cell, composed largely of actin filaments, microtubules and intermediate filaments
cyto skeleton
A complex of DNA and proteins, primarily histones, in the cell nucleus that stains readily with basic dyes and condenses to form chromosomes during cell division
chromatin
The organelle, located within the nucleus and not bounded by a membrane, that is the location of ribosomal RNA synthesis and the assembly of ribosomal subunits
nucleolus
An organelle in eukaryotic cells that stores and modifies proteins then sorts them and sends them to particular parts of the cell
golgl apparatus
A membrane-enclosed structure within a cell, such as a mitochondrion, vacuole, or chloroplast, that performs a specific function
organelle
A membrane-bound organelle in the cytoplasm of most eukaryotic cells containing carious hydrolytic enzymes that function in intracellular digestion
lysome
A chlorophyll containing organelle found in algal and green plant cells and is the site of photosynthesis
chloroplast
The process in which a cell takes up solutes or particles by enclosing them in vesicles pinched off from its plasma membrane
endocytosis
A large, membrane-bound, usually spherical protoplasmic structure within a living cell, containing the cell’s hereditary material and controlling its metabolism, growth, and reproduction
nucleus
The eukaryotic organelle that is the site of electron transport, oxidative phosphorylation, and pathways such as the Krebs cycle. It is the site of cellular respiration
mitochondria
