Exam 1-Ex. 3&4 Flashcards
External boundary of cell;regulates flow of materials into and out of the cell
Plasma Membrane
Contains digestive enzymes for many varieties; “Suicide Sac” of the cell
Lysosomes
Scattered throughout the cell;Major site of ATP Synthesis
Mitochondria
Slender extensions of the plasma membrane that increase its surface area
Microvilli
Stored glycogen granules, crystals, pigments, and so on
Inclusions
Membranous system consisting of flattened sacs and vesicles;packages proteins for export
Golgi Apparatus
Control center of the cell; Necessary for cell division and cell life
Nucleus
Two rod-shaped bodies near the nucleus;Basis of cilia
Centrioles
Dense,darkly staining nuclear body; Packaging site for ribosomes
Nucleolus
Contractile elements of the cytoskeleton
Microfilament
Membranous system that has smooth and rough varieties
Endoplasmic Reticulum
Attached to membrane systems or scattered in the cytoplasm; Synthesize proteins
Ribosomes
Threadlike structures in the nucleus; Contain genetic materal
Chromatin
Site where harmful chemicals are detoxified
Peroxisome
Chromosomes line up in the center of the cell
Metaphase
The chromosomes are V-shaped
Anaphase
Chromosomes stop moving towards the poles
Anaphase
Chromatin coils and condenses, forming chromosomes
Prophase
Nuclear envelope fragments
Prophase
Mitotic spindle forms
Prophase
Chromosomes first appear to be double
Prophase
Chromosomes attach to the spindle fibers
Prophase
Nuclear envelope is absent
Prophase
Movement from higher concentration to lower concentration
Diffusion
Diffusion of water through semi-permeable membrane
Osmosis
No energy required
Passive
Energy required
Active
