Answer 1

• nucleus
• mitochondria
• cell membranes
• cytoplasm
• ribosomes

Question 2

What are the three things plant cells have and animal cells do not?

Answer 2

• vacuole
• cell wall
• chloroplast

Question 3

Where is the genetic material found in in an animal cell?

Answer 3

Nucleus

Question 4

Where is the genetic material found in a bacteria cell?

Answer 4

Single circular strand of DNA

Question 5

What type of organism are bacteria ?

Answer 5

Prokaryotes

Question 6

What gives a higher resolution a light or electron microscope?

Answer 6

Electron

Question 7

Name the sub cellular structures where aerobic respiration takes place ?

Answer 7

Mitochondria

Question 8

Giveaways animal cells differ from plant cells ?

Answer 8

• cell wall
• vacuole
• chloroplasts

Question 9

Give the differences of prokaryotic and eukaryotic cells

Answer 9

• prokaryotic cells are smaller
• prokaryotic cells have mitochondria
• prokaryotic cells don’t have a true nucleus
• prokaryotic cells have circular DNA

Question 10

Why Microsoft should be used to look at the internal structure of a chloroplast?

Answer 10

Electron

Question 11

What is the function of a chloroplast ?

Answer 11

They absorb light needed for photosynthesis to make food for the plant

Question 12

What s the unction of a ribosome ?

Answer 12

They’re where proteins are made in a cell

Question 13

What type of organism are plants and animals?

Answer 13

Eukaryotes

Question 14

Why is an Electron microscope better than a light microscope?

Answer 14

Has a much higher magnification and resolving power

this means it can be used to study cells in much finer details

this has enabled biologist to see and understand Mossop cellular structures

Question 15

Describe the nucleus

Answer 15

Contains genetic material that controls activities of the cell

Question 16

Describe mitochondria

Answer 16

These are where most of the reactions for aerobic respiration take place

respiration transfers energy that the cell needs to work

Question 17

Describe the cytoplasm

Answer 17

I gel like substance where most of the chemical reactions happen

it contains enzymes that control these chemical reactions

Question 18

Describe the cell membrane

Answer 18

Holds the cell together and controls what goes in and out

Question 19

Describe ribosomes

Answer 19

These are where proteins are made in the cell

Question 20

Describe the cell wall

Answer 20

Original wall made of Celulose

it supports and strengthens the cell

Question 21

Describe the permanent vacuole

Answer 21

Contains cell sap a weak solution of sugar and salt

Question 22

Describe chloroplasts

Answer 22

These are where photosynthesis occurs which makes the food for the plant

they contain green substance like chlorophyll

which absorbs light needed for photosynthesis

Question 23

What is the resolution of the microscope?

Answer 23

The ability to distinguish between two points

so higher resolution give the sharper image

Question 24

Why do we add a drop of iodine solution when observing a slight?

Answer 24

It stings and highlights objects by adding colour to them

Question 25

What part of the onion do you use?

Answer 25

The epidermal tissue
