B1- Cell Structure And Transport

Question 1

Nucleus

Answer 1

Contains the genetic infomation of the cell (10um, micrometres,in diameter)

Question 2

Plasmid

Answer 2

Simular to nucleus, it holds the genitic infomation and can be transfered from one bacteria cell to another , they are small rings of DNA.

Question 3

Cytoplasm

Answer 3

This is where all the chemical reactions take place in a cell

Question 4

Cell wall

Answer 4

This maintains the cells structure and is made up of cellulose

Question 5

Mitochondria

Answer 5

This is where respiration takes place within the cell (0.2 - 0.7 um, micrometres, in diametre)

Question 6

Ribosomes

Answer 6

This is where the cell produces proteins

Question 7

Membrane

Answer 7

This is controls what comes in and out of the cell

Question 8

Chloroplast

Answer 8

This made up of chlorphyll and is where photosynthesis take place in a plant cell

Question 9

Flagella

Answer 9

This allows the movement of certain cells (e.g sperm cell)

Question 10

Vacuole

Answer 10

This is located in the cytoplasm and stores cell sap

Question 11

Genetic material

Answer 11

Commonly found in eukaryotic cells and is located in the cytoplasm, it determines the composition of that organism

Question 12

Slime capsule

Answer 12

A layer surrounding the cell wall which make its harder for the bateria to be engulfed in phagocyte (cells capable of engulfing small cells or bacteria)

Question 13

Eukaryotes

Answer 13

They have a cell membrane, cytoplasm and genetic material enclosed in a nucleus.

Question 14

Prokaryotes

Answer 14

They have cytoplasm and a cell membrane surrounded by a cell wall however The genetic material is not enclosed in a nucleus. It is a single DNA loop.

Question 15

Animal cell

Answer 15

An animal cell is a eukaryotic cell, about 10-30um, micrometres, in length)

Question 16

Plant cell

Answer 16

Plant cells are eukaryotes and range from 10-100um, micrometres, in length)
