Flashcards in Photosynthesis Deck (15):
1

Word equation

Carbon dioxide + water -------- glucose + oxygen

2

In photosynthesis where is energy stored

Glucose molecules

3

In photosynthesis where is energy transferred to

Animals when they eat the plants

4

What can glucose be converted to and why

Starch and stored for later use.
Starch molecules are big and unlike glucose cannot diffuse out of cells

5

What's white light

A continuous spectrum from of colours from red to violet

6

What colour is short wavelength light

Blue

7

What colour is long wavelength light

Red

8

What's light energy absorbed by

Chlorophyll and found in the chloroplasts of plants cells

9

Why does chlorophyll look green

Because it absorbs the blue and red parts of the spectrum and reflects the green part

10

What's glucose made from

Carbon hydrogen and oxygen atoms

11

How do you convert glucose into proteins

Plants need nitrogen which they get in the form of mineral ions . They normally use nitrate ions and absorb them from the soil through their roots

12

What do most plants store at lesser some energy as

Starch

13

What's starch

A polymer made up of many glucose molecules linked together in a long chain

14

Unlike glucose starch is insoluble, how?

It forms grains inside cells instead of dissolving and getting mixed up with everything else inside the cell

15

How many more energy per gram can fats and oils store in comparison to carbohydrates

Twice the amount per gram but it's more difficult to make them and break them down
