Cell Parts

Question 1

what is the cell theory?

Answer 1

all living things are composed of cells, cells are the building blocks of life, all cells come from other cells (and can only come from other cells)

Question 2

organelle

Answer 2

they do the jobs of a cell, depend on each other and work together

Question 3

cell wall

Answer 3

rigid layer of non-living material for protection and support IN PLANT CELLS ONLY (wall/cinder blocks of classroom)

Question 4

cell membrane

Answer 4

gatekeeper of cell, decides what enters and leaves (screen or fishnet) in both types of cells

Question 5

nucleus

Answer 5

organelle that contains genetic materials (DNA), directs cell’s activities, in both types of cells, control center/CEO/ownership group

Question 6

nuclear membrane

Answer 6

thin layer surrounding nucleus, protects nucleus and denies what comes in and out, in both types of cells, gate-keeper

Question 7

chloroplast

Answer 7

green bean-shaped structure with chlorophyll (green), turns sun’s energy into food (glucose-sugar) by photosynthesis IN PLANTS ONLY (kitchen-makes food but doesn’t eat it)

Question 8

mitochondria

Answer 8

rod-shaped with a folded membrane inside, breaks down sugar for energy, in both types of cells, (people eating food)

Question 9

Endoplasmic Reticulum (ER)

Answer 9

smooth or rough folded membrane, carries proteins and tother materials through the cell - transport for protein-related things, in both types of cells, (waitress caries food, ambulance-ER!)

Question 10

Ribosome

Answer 10

Small bead-shaped organelle that produces the final product of protein for cell, in both types of cells, (construction workers, DNA–>RNA–>Protein) mutations are ribosome mistakes

Question 11

Golgi bodies

Answer 11

flattened pouches arranged in layers, receives proteins and other materials, packages and ships them, in both types of cells (post office/UPS)

Question 12

Vacuole

Answer 12

large membrane-bound pouch that stores food, water, and other materials, in both types of cells LARGER AND MORE IMPORTANT IN PLANTS (storage/water balloons/vacuum)

Question 13

lysosome

Answer 13

pocket of enzymes (things that break things down in a cell), enzymes digest food and dead cell parts, in both types of cells but ANIMAL CELLS HAVE MORE, (disposal/compost/breaking down)

Question 14

chromatin

Answer 14

DNA folded up like spaghetti, Is genetic information (DNA) with proteins, in both types of cells, (code in nucleus/instructions)

Question 15

cytoplasm

Answer 15

jelly-like substance that fills the cell, fills in space and allows transport, in both types of cells, (air/public bus)

Question 16

what is a cell trying to make?

Answer 16

Protein

Question 17

Who makes the cell’s final product?

Answer 17

Ribosomes

Question 18

Place the following terms in order of complexity: organs, cells, tissues, organ system

Answer 18

cells, tissues, organs(heart/brain), organ systems (nervous/respiratory)

Question 19

How are plant and animal cells different?

Answer 19

Plant cells and animal cells are different because there are more Lysosomes in animal cells, larger and more important vacuoles in plant cells, no chloroplasts in animal cells (only in plants), and only plant cells have a cell wall.

Question 20

Why do some cells become specialized?

Answer 20

Some cells become specialized to do a specific job or to make a specific protein.

Question 21

What is the main job of the cell?

Answer 21

The main job of a cell is to build protein.
