Chapter 6 Flashcards
The genetic control center of a eukaryotic cell, governing everything that the cell can do.
Nucleus
Grainy appearing DNA in the nucleus of a non-dividing cell.
Chromatin
DNA condensed during the processes of cell division.
Chromosomes
Regulates all the materials entering and leaving the nucleus.
Nuclear Membrane
Responsible for the synthesis of ribosomes.
Nucleolus
Located just outside of the nucleus; makes more membrane; produces proteins that are exported out of the cell.
Rough Endoplasmic Reticulum
Synthesis of lipids, some of which are part of the cell membrane.
Smooth Endoplasmic Reticulum
Finishes and/or modifies, stores and ships cell products to different destinations.
Golgi Apparatus
A membranous sac of digestive (hydrolic) enzymes that breaks down cellular material; releases digestive enzymes into food vacuoles.
Lysosome
The digestion of damaged organelles.
Autophagy
Very large and in plant cells only; growth of plant cells by absorbing water; storage of cellular materials.
Central Vacuole
Water balance in freshwater organisms.
Contractile Vacuole
Site of photosynthesis; contain DNA.
Chloroplast
Cell’s powerhouse; the site of cellular respiration; contains DNA
Mitochondria
The transformation of chemical energy stored in food into ATP.
Cellular Respiration
A network of fibers that provide structural support and motility; helps the cell maintain its shape.
Cytoskeleton
Microfilaments, microtubules, intermediate filaments.
Uses of Cytoskeleton
Short hairs; found in large numbers.
Cilia
Long “whips” used for locomotion and for generating water currents; generate water currents to bring nutrients to the cells and aid in carrying wastes away from the cell.
Flagella
Protects the cell; provides support; not found in animal cells.
Cell Wall
