Questions on :cells and tissues I-Define -cell inclusions -solution -passive transport -active transport -selective permeability -diffusion -filtration -osmosis -osmotic pressure -isotonic, hypertonic, hypotonic solution -pinocytosis -interphase -tissue -micovilli -cell life cycle II-Enumerate -types of connective tissue fibers -examples of dense connective tissue -types of cartilage -functions of connective tissue -types of glands -characters of connective tissue -types of bulk transport -the main components of a cell - the main components of a nucleus -types of membrane junctions - the main components of cytoplasm -the organelles -stages of mitosis -fluid compartments -passive transport processes -active transport processes -the main four elements found in the cell -main components of plasma membrane -characters of substances that do not pass by diffusion -the primary tissue types -main characters of epithelial tissue -functions of epithelial tissue -five examples of epithelium and its site -types of muscles and characters of each -parts of neuron and draw it -types of tissue repair III-Fill spaces ---------------tissue is commonly called fat ----------------------cells are commonly called signet ring cell -the nonliving matrix of blood is------------------while the fibers are------------the most abundant cartilage is-----------------------1 -the ability of a barrier to allow some substances to pass while excluding other is called----------------------the most rigid connective tissue is----------while the softest one is--------------------periods of cell life cycle are-----------------and-------------toward the end of interphase period,the genetic material is-----------------division of the nucleus is called --------------while of cytoplasm is called------------collectively, the nucleoplasm and cytosole are called-----------------about -------of the cell is water -exchange between cells and blood is made through-----------------fluid -cells are bathed in a dilute solution called-------------the headquarter of the cell is--------------------ribosomes are assembled in------------------when the cell is not dividing,DNA is called---------------during cell division,chromatin condenses to form--------------plasma membrane is formed mainly of--------------------the powerhouse in the cell is-----------the site of protein synthesis is ------------------the minicirculatory system for the cell is----------------------rough ER is so called because it is studded with-----------------during cell division,------------------directs the formation of spindle -cell shape is determined by----------------- which is a network of proteins -cells that cover and line body cavity is called----------------cells of reproduction are------------------&------------------the tendency of a solution to hold water is called---------------------hypertonic solution leads to-----------------of red cells - hypotonic solution leads to-----------------of red cells -three of trace elements important for cell and function of each -the control center of the cell is------------when cell is not dividing, DNA is called--------------when adjacent plasma membranes fuse together tightly like a zipper it is called --------------------------are buttonlike thickening of adjacent plasma membranes ------------------type of membrane junctions common in the heart to allow communication -------------------is the cellular material outside the nucleus and inside plasma membrane -the metabolic machinery of the cell is---------------------cellular not functioning units are called---------------------examples of inclutions are--------------------,---------------,------------------membrane bags containing digestive enzymes are called----------------cellular network acts as bones and muscles called----------------------------------is a paired rod-shaped bodies lies close to the nucleus, it directs the formation of mitotic spindle --------------------are whip like extensions that move substances along the cell surface -the only example of a flagellated cell in human body is the ---------------------------------------are example of cells that store nutrients --------------------are example of cells that fight disease --------------------are cells that cover and line body organs -male cell of reproduction is-------------while that of female is-------------------------------and---------------are example of cells that connect body parts -in ---------------------fluids move down their concentration gradient -the unassisted diffusion is called---------------diffusion of water through plasma membrane is called-----------------------2 -sodium –potasium pump are examples of------------------------------------------is called cell eating while ------------------ is called cell drinking VI-True or false -bone regenerate beautifully -all cells undergo mitosis until the end of puberty -cells exposed to friction can replace lost cells throughout life -nerve tissue become amitotic years after birth -skeletal muscles regenerate poorly, if at all -most connective tissues are well vascularized -cartilage ia avascular -tendons and ligaments are poorly supplied with blood -in mitosis, the daughter cell has the same genetic material as the mother cell -in meosis, the daughter cell has the same genetic material as the mother cell -filtration is a passive process -facilitated diffusion is a passive process - glucose is both lipid - insoluble and too large to pass through membrane pores - glucose pass through membrane by facilitated diffusion -facilitated diffusion needs a protein carrier -in filtration, hydrostatic pressure is exerted by the blood -all molecules posses kinetic energy -ovum is the largest cell in the body -the higher the solute concentration, the greater the osmotic pressure -isotonic solution cause no visible changes in cells - the nuclear membrane is selectively permeable - the nuclear membrane has relatively larger pores than plasma membrane -the nucleus always have one nucleolus -rough ER is abundant in cells that export proteins -smooth ER functions in cholesterol synthesis -metabolically active cells have hundreds of mitochondria -mitochondria is the site where oxygen is used to breakdown foods -lysosomal rupture results in self-digestion of the cell -both solute pumping and facilitated diffusion need carrier protein V-Match Table A ( ) filteration ( ) diffusion ( ) solute pumping ( ) facilitated diffusion ( ) active transport ( ) pinocytosis ( ) phagocytosis Table B 1- ATP is needed 2-pressure gradient 3-concentration gradient 4- sodium –potassium transport 5-protein carrier is needed 6- cell eating 7- cell drinking 8-isotonic solution 3
