Cell Structure And Cell Division

Question 1

Eukaryotic cell

Answer 1

The building blocks of living organisms, these have a true nucleus with genetic material

Question 2

Organelle

Answer 2

A structure within a cell with a certain role

Question 3

Cell membrane

Answer 3

Around the cell, this controls what enters and leaves

Question 4

Nucleus

Answer 4

The part of the eukaryotic cell that contains genetic material and controls the cell

Question 5

Cytoplasm

Answer 5

A jelly like substance within the cell where the reactions take place

Question 6

Ribosomes

Answer 6

The site of protein synthesis (making) in cells

Question 7

Mitochondria

Answer 7

The site of aerobic respiration to release energy for the cell

Question 8

Vacuole

Answer 8

Contains cell sap and helps support the cell

Question 9

Chloroplast

Answer 9

Found in plant cells, this produces sugar (glucose) by the process of photosynthesis

Question 10

Cell wall

Answer 10

Made of cellulose, helps support the cell giving it shape

Question 11

Stem cell

Answer 11

When a cell has the potential to become any cell type. Found in early embryos and adult bone marrow

Question 12

Differentation

Answer 12

When a cell becomes specialized

Question 13

Specialized cell

Answer 13

A cell that is adapted to do a particular job

Question 14

Prokaryotic cell

Answer 14

These cells have a cytoplasm and cell membrane surrounded by a cell wall. They have no true nucleus. The DNA is in a single loop

Question 15

Flagella

Answer 15

A long protein strand that can be used for movement in prokaryotic cells

Question 16

Slime capsule

Answer 16

A protective coat found on the outside of some prokaryotic cells

Question 17

Light microscope

Answer 17

Uses a beam of light to observe objects . Relatively cheap with a maximum magnification of about x2000

Question 18

Electron microscope

Answer 18

Uses a beam of electrons to observe objects.

Question 19

Magnification

Answer 19

The number of times bigger an image appears than the actual size of the object

Question 20

Resolution

Answer 20

The ability to distinguish between two separate points

Question 21

Chromosome

Answer 21

Found in the nucleus, these are thread like structures of DNA that carry the genes

Question 22

DNA

Answer 22

The molecule of inheritance

Question 23

Gene

Answer 23

A short section of DNA found in chromosomes, that controls characteristics.

Question 24

Mitosis

Answer 24

A form of cell division that occurs in the body cells for growth, repair and replacement. This usually results in 2 genetically identical daughter cells

Question 25

Karyotype

Answer 25

The number and appearance of chromosomes in the nucleus of a eukaryotic cell
