Flashcards in Cells And Microsocpy Deck (25):
1

Name the sub cellular structures of both plants and animals

•nucleus
•mitochondria
•cell membranes
•cytoplasm
•ribosomes

2

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

•vacuole
•cell wall
•chloroplast

3

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

Nucleus

4

Where is the genetic material found in a bacteria cell?

Single circular strand of DNA

5

What type of organism are bacteria ?

Prokaryotes

6

What gives a higher resolution a light or electron microscope?

Electron

7

Name the sub cellular structures where aerobic respiration takes place ?

Mitochondria

8

Giveaways animal cells differ from plant cells ?

•cell wall
•vacuole
•chloroplasts

9

Give the differences of prokaryotic and eukaryotic cells

•prokaryotic cells are smaller

•prokaryotic cells have mitochondria

•prokaryotic cells don’t have a true nucleus

•prokaryotic cells have circular DNA

10

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

Electron

11

What is the function of a chloroplast ?

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

12

What s the unction of a ribosome ?

They’re where proteins are made in a cell

13

What type of organism are plants and animals?

Eukaryotes

14

Why is an Electron microscope better than a light microscope?

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

15

Describe the nucleus

Contains genetic material that controls activities of the cell

16

Describe mitochondria

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

respiration transfers energy that the cell needs to work

17

Describe the cytoplasm

I gel like substance where most of the chemical reactions happen

it contains enzymes that control these chemical reactions

18

Describe the cell membrane

Holds the cell together and controls what goes in and out

19

Describe ribosomes

These are where proteins are made in the cell

20

Describe the cell wall

Original wall made of Celulose

it supports and strengthens the cell

21

Describe the permanent vacuole

Contains cell sap a weak solution of sugar and salt

22

Describe chloroplasts

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

they contain green substance like chlorophyll

which absorbs light needed for photosynthesis

23

What is the resolution of the microscope?

The ability to distinguish between two points

so higher resolution give the sharper image

24

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

It stings and highlights objects by adding colour to them

25

What part of the onion do you use?

The epidermal tissue
