cell parts

Question 1

lysosome

Answer 1

found in the animal cell and is formed by the golgi body. it carries enzymes that break down large molecules and cell parts. suicide sac

Question 2

vacoule

Answer 2

big in the plant cell and small in the animal cell. basically a storage unit.

Question 3

cytoskeleton

Answer 3

mricotubulues: tube like
microfilamnets: hair like

Question 4

centrioles

Answer 4

only found in an animeal and plays a key roll is cell divison

Question 5

golgi body

Answer 5

-“stacked pancakes” forms lysosomes
-stores, modifies, and packages proteins from the roughER.
-pinches off to fill small protein vesicles

Question 6

ribosomes

Answer 6

-attached to the roughER or floating in the cytoplasm
- site of protein synthesis
- amino acids are joined together to make proteins
- the smallest organelles
- made up of RNA and proteins

Question 7

rough endoplasmic reticulum (roughER)

Answer 7

• an organelle with a double membrane with ribosomes attached
• extends from the nuclear membrane to the cell membrane
• transports proteins made by the ribosome to the golgibody

Question 8

smooth endoplasmic reticulum (smoothER)

Answer 8

• double membrane bound organelle without ribosomes
• extends throughout the cell
• produces lipids for the cell

Question 9

plastids

Answer 9

• chemical factories or store houses for food/pigments
• chloroplasts: contain chlorophyll and are the site of photosynthesis
• chromoplasts: store pigments (orange and yellow)
• amyloplasts- colorless and store startch

Question 10

cell wall

Answer 10

• protects and supports the cell
• primary cell wall mad of cellulose
• plants and prokaryotic cells

Question 11

cytoplasm

Answer 11

• jelly like substance that fills the interior of the cell
• many metabolic reaction occur within the cytoplasm

Question 12

cilia

Answer 12

cilia (cilium) are shorter hair like structues that aid in movement

Question 13

flagella

Answer 13

longish, whip like tail that aids in movement and they spin like a propeller

Question 14

pili

Answer 14

allows attachment to other
bacteria/other surfaces, DNA exchange

Question 15

cell membrane

Answer 15

• outermost boundary of the cell
• made up of proteins and a bilayer (double) of lipid (fat) molecules
• holds the cell content in place
• regulates the movement of materials in and out of the cell

Question 16

nucleus

Answer 16

• control center of the cell
• contains chromosomes made of genes, chromosomes and DNA (chromatin)
• pores in the nuclear enevlope allow some things to pass through
• double membrane

Question 17

nucleolus

Answer 17

• located inside the nucleus
• cells contain one or more nucleoli
• they produce ribosomes

Question 18

mitochondira

Answer 18

• the “powerhouse of the cell”
• oval shaped with a double membrane
• a smooth outer and an inner folded membrane called the cristae
• site of cellular respiration
• energy is released from sugar and energy stored in ATP
• mitochondria contain their own DNA

Question 19

vesicles

Answer 19

• small bubble within a cell
• used for metabolism, transport, buyoncy control, enzyme storage, chemical reaction chambers
• types: normal vesicles, transport, secretory, and lysosmes

Question 20

peroxisomes

Answer 20

membrane bound oragnelle contains enzymes involved in energy metabolism (mostly fats)
