Cell structure

Question 1

What is the difference between a prokaryote and an eukaryote?

Answer 1

Prokaryote has no nucleus, these are mostly bacteria. An eukaryote has an enclosed nucleus, these are plant and animals.

Question 2

Cytoplasm

Answer 2

A jelly-like substance that supports the organelles inside

Question 3

Cell membrane

Answer 3

Encloses the cell contents, semi-permeable membrane

Question 4

Nucleus

Answer 4

Contains DNA, direct activities of the cell

Question 5

Chromosomes

Answer 5

46 in every cell, chromosomes are for eukaryote cells

Question 6

Endoplasmic reticulum

Answer 6

A system of channels from the nucleus, ribosomes cause er to be rough. A smooth er would be lacking ribosomes.

Question 7

Golgi apparatus

Answer 7

Collect, package, and distribute molecules synthesized at one location in the cell and utilized at another location.

Question 8

Lysosomes

Answer 8

Membrane-bound vesicles containing digestive enzymes, these enzymes break down food particles and destroys old cell parts

Question 9

Ribosomes

Answer 9

Site of protein synthesis, assembled in nucleolus

Question 10

Mitochondria

Answer 10

Converts glucose to usable energy for the cell (ATP), powerhouse.

Question 11

Chloroplast

Answer 11

Only in plants cells, have special pigment molecules called chlorophyll that absorb sunlight and convert it into glucose.

Question 12

What do only plant cells have?

Answer 12

Chloroplasts, central vacuole, and cell wall

Question 13

What do only animal cells have?

Answer 13

The centriole, which plays a role in cell division.
