The Cell (Ch5)

Question 0

Chromoplast (60)

Answer 0

Stores carotenoids pigments and are responsible for the orange-yellow coloring of carrots, tomatoes, etc to attract pollinating insects

Question 1

Leucoplast (60)

Answer 1

Colorless and store starch in plants; found in roots, like turnips, or in tubers, like potatoes

Question 2

Microtubules (61)

Answer 2

Thick hollow tubes that make up the cilia, flagella, and spindle fibers

Question 3

Microfilaments (61)

Answer 3

Made of the protein actin and help support the shape of the cell; enables cleavage furrows, amoeba movement through pseudopods, and skeletal muscles to contract by sliding along myosin filaments

Question 4

Chromatin network (58)

Answer 4

Chromosomes made of DNA that is wrapped with special proteins called histones

Question 5

Plastids (60)

Answer 5

Found in plants and algae; have a double membrane; includes chloroplasts, leucoplasts, and chromoplasts

Question 6

Centrioles / Centrosomes (61)

Answer 6

Outside the nuclear envelope and organize the spindle fibers; only in animal cells; two centrioles at right angles make one centrosome; one centriole has nine triplets of microtubules

Question 7

Cilia / Flagella (61)

Answer 7

Cilia are short, flagella are long; both have 9 pairs of micro tubules around 2 singlet micro tubules (9 + 2)

Question 8

Chitin (62)

Answer 8

Makes up cell walls of fungi

Question 9

Cellulose (62)

Answer 9

Makes up the cell walls of plants and algae

Question 10

Middle lamella (62)

Answer 10

A thin gluey layer formed between the two cell walls (primary and secondary) that keeps daughter cells attached

Question 11

Cytosol (62)

Answer 11

The semiliquid portion of the cytoplasm (which is the region between the nucleus and plasma membrane)

Question 12

Cyclosis (62)

Answer 12

A process where organelles are suspended in the cytosol and get carried around the cell as the cytoplasm cycles
