observed that the tissues of plants contained cells

Question 6

what did Rudolf Virchow do?

Answer 6

said every living thing is made up of cells and predicted cells come from other pre-existing cells

Question 7

what is the cell theory?

Answer 7

1. Every living organism is made up of one or more cells. 2. The cell is the most basic unit of life. 3. all cells come from pre-existing cells

Question 8

what is the function of the ribosome?

Answer 8

makes protein to be used by an organism

Question 9

what is the cytoplasm?

Answer 9

jelly-like goo on the inside of the cell to provide shape for the cell

Question 10

what is DNA and what does it stand for?

Answer 10

is the genetic material and stands for Deoxyribonucleic acid

Question 11

what is the cytoskeleton?

Answer 11

the internal skeleton of the cell

Question 12

what is the function of the cell membrane?

Answer 12

provides protection for a cell

Question 13

what are the 2 types of cells?

Answer 13

prokaryotic and eukaryotic

Question 14

describe prokaryotic cells

Answer 14

doesn’t have a nucleus or membrane-bound organelle.

Question 15

describe eukaryotic cells

Answer 15

do have a nucleus and membrane-bound organelle

Question 16

Pilus

Answer 16

small hairlike structures used for attaching to other cells

Question 17

Capsule

Answer 17

a tough outer layer that protects bacteria, often associated with harmful bacteria

Question 18

nucleus

Answer 18

Usually found at the center of the cell and contains an organelle called nucleolus

Question 19

nucleolus

Answer 19

makes the cell’s ribosomes

Question 20

Mitochondria

Answer 20

turns food into useable energy (ATP)

Question 21

Golgi Apparatus

Answer 21

processing, packages and secretes proteins; proteins are transported in vesicles

Question 22

Lysosome

Answer 22

contains digestive enzymes that can break things down, also called a “suicide sac” because the rupturing of the lysosome will cause the cell to destroy itself

Question 23

Endoplasmic Reticulum

Answer 23

Transport, “intracellular highway”. Ribosomes are positioned along the rough ER, protein made by the ribosomes enter the ER for transport.

Question 24

Cytoskeleton

Answer 24

helps maintain the cells shape; supports the cell and aids in cell movement

Question 25

Vacuole

Answer 25

storage area for water and other substances, plant cells usually have a large central vacuole
