CELLS Structure & Function Review
2
Which kind of cell is the largest? animal cell plant cell Bacteria Plant cells are the biggest What do we call membranes that allow certain molecules to pass through but not others? Selectively permeable OR semi-permeable
3
Which kind of cell is the smallest? animal cell plant cell Bacteria Bacterial cells are the smallest Which molecule found in cell membranes helps cells “recognize self” ? glycoproteins
4
Cell membranes are made of these 2 main kinds of molecules. Phospholipids & proteins Which cell organelles burn glucose and store energy as ATP? mitochondria
5
Phospholipids form bilayers in cell membranes because their hydrophobic _______ are trying to stay away from water. tails Name a cell part with a DOUBLE MEMBRANE around it Nucleus, mitochondria, chloroplasts
6
What is the dark spot in the nucleus called? nucleolus What do we call DNA that is TIGHTLY PACKED in DIVIDING CELLS? chromosomes
7
What is the gel-like material and organelles called inside the cell membrane? cytoplasm What do we call DNA that is SPREAD OUT in NON-DIVIDING CELLS? chromatin
8
What are the folded membranes inside mitochondria called? cristae Which organelle looks like a “stack of pancakes”? GOLGI body
9
Tell what this molecule does “self” identification Tell what this molecule does Store and transfer energy http://faculty.clintoncc.suny.edu/faculty/Michael.Gregory/files/Bio%20101/Bio%20101%20Lectures/Membranes/membrane.htm
10
Which part of a phospholipid is HYDROPHILIC? head tails Heads are hydrophilic TRUE or FALSE ALL CELLS have a cell membrane TRUE, plant, animal, and bacterial cells all have a CELL membrane
11
Which part of a phospholipid is HYDROPHOBIC? head tails Tails are hydrophobic TRUE or FALSE ALL CELLS have a nuclear membrane FALSE; only plant and animal cells (eukaryotes) have a NUCLEAR membrane. NOT bacteria (prokaryotes)
12
Tell which part does it? Burns glucose & stores energy as ATP __________________ Controls what enters or leaves the cell _________________ Sort & package substances for transport out of cell _________________ Makes ribosomes ______________________ Control center of cell ___________________ Mitochondria Cell membrane Golgi bodies nucleolus nucleus
13
Name this organelle Mitochondria What does it do? Powerplant of cell; Burn glucose and store energy as ATP
14
Name this molecule found in cell membranes phospholipid http://biology.clc.uc.edu/courses/bio104/cells.htm
15
Name this molecule found in cell membranes centrioles Name this cell part Pull chromosomes apart http://www.beyondbooks.com/lif71/4a.asp
16
_________ ER does NOT have ribosomes attached Smooth Organelle in a plant or animal cell that contains the cell’s genetic material. nucleus
17
The blue part of this phospholipid molecule stays inside the membrane away from water because it is ______________. hydrophilic hydrophobic hydrophobic
18
Cell suicide for the good of the organism is called ____________ APOPTOSIS Cells that have a nuclear membrane and membranes around their organelles are called ________________ eukaryotes
19
Name the sacs found inside chloroplasts that contain the molecules for photosynthesis thylakoids Centrioles are only found in ________ cells plant animal bacteria ANIMAL
20
Name this part. Tell what it does? Make lipids/steroids; Regulate calcium; Break down toxins Smooth ER
21
Name this cell organelle Golgi body Tell what it does Sort and package molecules for transport out of cell http://vilenski.org/science/safari/cellstructure/golgi.htm
22
Tell which part does it? Pulls chromosomes apart _________________ Power plant ___________________ Surrounds the DNA & controls what enters/leaves nucleus____________________ Supports and protects bacterial cells ___________________ Make proteins _______________________ centrioles Mitochondria Nuclear membrane Cell wall ribosomes
23
What’s the function? Mitochondria ____________________ Ribosomes ___________________ Cell wall __________________ Golgi bodies ____________________ Centrioles ________________ Smooth ER ___________________ Power plant;burn glucose; make ATP Make proteins support; protection Package molecules for export Pull chromosomes apart Make steroids; regulate calcium; Break down toxins in liver
24
What’s the function? Rough ER ____________________ nucleus ___________________ cell membrane ____________________ chloroplast ________________ vacuole ___________________ nucleolus ________________________ Highway in cell Contains DNA; control center Controls what enters/leaves cell photosynthesis Stores water, food, molecules, waste Make ribosomes
25
Tell which part does it? Burns glucose ____________________ Controls what enters or leaves the cell ___________________ Pulls chromosomes during cell division __________________ Digests unwanted substances or cell parts _______________ Makes proteins ______________________ Contains DNA ___________________ Mitochondria Cell membrane Centrioles Lysosomes Ribosomes Nucleus
26

28
Endoplasmic reticulum with ribosomes attached is called _________ ER. rough Membrane bound sac that contains digestive enzymes. lysosome
29
A plant cell is a ______________. prokaryote eukaryote eukaryote These organelles helps with APOPTOSIS and are also called “suicide sacs” lysosomes
30
Cells that DO NOT have a nuclear membrane OR membranes around their organelles are called ________________ PROKARYOTES Name the cell part that makes this molecule Mitochondria make ATP RIBOSE
