Plants

Question 1

What supports the the flower and carries the food and water?

Answer 1

Stem

Question 2

What dies the flower do?

Answer 2

It attracts insects for pollination so it can reproduce

Question 3

What do the roots do?

Answer 3

They absorb water and nutrients from the ground and help the plant stay up right.

Question 4

What is the photosynthesis equation?

Answer 4

Carbon dioxide + water (+sunlight) = glucose + oxygen

Question 5

How do we test a leaf for starch to see if photosynthesis has occurred

Answer 5

Add iodine - if it turned black it has done photosynthesis

Question 6

What makes the plant green

Answer 6

Chlorophyll

Question 7

What does the chlorophyll do

Answer 7

Helps absorb lots of photosynthesis

Question 8

What is the stomata?

Answer 8

Holes in the leaf to allow carbon dioxide to travel into the leaf

Question 9

Guard cells do what?

Answer 9

Open and close the stomata

Question 10

What is biomass

Answer 10

It is a material made from living things, it can be used as a fuel and will never run out (renewable)

Question 11

What are the male plants of a plant?

Answer 11

The stamen is the main male thing containing the male parts of the filament and anther

Question 12

What does the stigma do?

Answer 12

Sticks pollen to the stigma

Sticky stigma

Question 13

What does the anther do?

Answer 13

Makes pollen

Question 14

What is germination?

Answer 14

Seeds producing a root and a shoot

Question 15

What is the independent variable?

Answer 15

Thing you change

Question 16

What is the Dependant variable

Answer 16

Thing you measure

Question 17

What is the control variables

Answer 17

Things you keep the same

Question 18

What conditions do seeds need to germinate in and their purpose?

Answer 18

Water - allows starch to dissolve in it so the germinated seed’s metabolism is easier
Oxygen - allows respiration to happen
Warmth - chemical reactions to happen faster because of the more particles

Question 19

What nutrients do plants need?

Answer 19

Iron - healthy green colour
Magnesium - makes chlorophyll
Phosphorus - makes the cell membranes and DNA

Question 20

What ways do seeds disperse?

Answer 20

Water
Animals
Wind
Exploding

Question 21

What does the waxy layer do?

Answer 21

Traps water inside the leaf

Question 22

What is glucose

Answer 22

The plants food

Question 23

What does photosynthesis do

Answer 23

Makes the plant’s food

Question 24

What do plants turn glucose into

Answer 24

Starch

Question 25

What is Cross pollination

Answer 25

Plants using another plant’s pollen for reproduction

Question 26

What does the seed coating do

Answer 26

Contains the egg cell - protects it

Question 27

What is the pollen tube

Answer 27

Carries the pollen nucleus down to the egg cell

Question 28

What does the style do

Answer 28

Connects the stigma to the ovary

Question 29

If a leaf has had iodine added and stayed green what hasn’t happened

Answer 29

Photosynthesis

Question 30

Look at plants and label them

Answer 30

Brilliant

Question 31

Label all diagrams

Answer 31

Keep going

Question 32

Why do leaves in the shade have a large surface area

Answer 32

So they can absorb the most sunlight as possible

Question 33

What is a xylem

Answer 33

It allows water to go into the leaf
