Cell Organelles And Homeostasis - Mrs.list

Front 1

Functions as the home for the organelles; the space in between the membrane and the nucleus; contains cytosol

Back 1

cytoplasm

Front 2

maintains cell shape, moves organelles, and moves cell; found only in euk.

Back 2

cytoskeleton

Front 3

contains the genetic material; like a control center; found only in euk.

Back 3

nucleus

Front 4

produces energy for the cell; like a generator; found only in euk.

Back 4

mitochondria

Front 5

synthesizes proteins; found in both prok. and euk.

Back 5

ribosomes

Front 6

processes and modifies proteins and manufactures fats; found only in euk.

Back 6

endoplasmic reticulum

Front 7

adds finishing touches and packages proteins for secretion; found only in euk.

Back 7

Golgi complex

Front 8

digests wastes or damaged organelles; found only in euk.

Back 8

lysosomes

Front 9

makes sugar; does photosynthesis; found only in euk.

Back 9

chloroplasts

Front 10

used for storage; found mainly in PLANT euk.

Back 10

vacuoules

Front 11

provides stability and protection; found in PLANT and FUNGI euk. or some prok.

Back 11

cell wall

Front 12

1700's Dutchman, made an accurate single lens microscope and studied pond life

Back 12

Antonie van Leeuwenhoek

Front 13

a whip-like protein structure projection that allows the organism to swim

Back 13

flagellum

Front 14

a grayish, gel-like liquid containing the nucleus, organelles, and cytoskeletion; like the water in a fish tank

Back 14

cytosol

Front 15

thick, hollow rods that provide a strong scaffold for the cell

Back 15

microtubules

Front 16

thin rods made of a protein called actin that are strung around the perimeter of the cell to help it withstand strain

Back 16

microfilaments

Front 17

a membrane separating the interior of the nucleus from the cytosol that only lets select molecules in and out

Back 17

nuclear envelope

Front 18

the stringy web of genetic material and histone proteins found in the nucleus of eu. cells

Back 18

chromatin

Front 19

a dense, spherical body inside the nucleus of a cell, makes the RNA that is a structural componen of the ribosomes

Back 19

nucleolus

Front 20

a compartment within the mitochondria formed by the second membrane where the chemical reactions of respiration of the cell take place

Back 20

mitochondrial matrix

Front 21

the process by which plants convert light energy into organic materials, such as glucose

Back 21

photosynthesis

Front 22

a pigment located within a chloroplast that absorbs light in plant cells

Back 22

chlorophyll

Front 23

type of liquid found in cell membranes; made up of a single hydrophilic phosphate head and two nonpolor hydrophobic lipid tails

Back 23

phospholipid

Front 24

the transport or natural drift of molecules traveling from an area of higher concentration to an area of lower concentration; does not requre outside energy

Back 24

diffusion

Front 25

process by which water naturally travels from an area of high water concentration to low water concentration

Back 25

osmosis

Front 26

a situation in which the concentration of solutes in a solution is lower than what an organism contains

Back 26

hypotonic

Front 27

a situation in which the concentration of solutes in a solution is higher than what it contains

Back 27

hypertonic

Front 28

a situation in which the concentration of solutes in a solution is equivalent to what it contains

Back 28

isotonic solution

Front 29

diffusion of molecules that cannot pass through the cell membrane independently, but rather through permeable protein channels embedded in the membrane; does not require outside energy

Back 29

facillitated diffusion

Front 30

process by which liquids or small solid particles are taken into a cell in the form of small vesicles that are produced through the invagination of the cell membrane

Back 30

endocytosis

Front 31

process by which molecules are secreted from the cell, occurs when a vesicle fuses with the cell membrane and releases its contents to the outside

Back 31

exocytosis

Front 32

type of endocytosis where the cell takes in large solid food particles that it then digests

Back 32

phagocytosis

Front 33

type of endocytosis where the cell takes in drops of cellular fluid containing dissolved nutrients

Back 33

pinocytosis
