Question 1

What is the word equation for photosynthesis?

Answer 1

Carbon dioxide + water —> glucose + oxygen

Question 2

What is the symbol equation for photosynthesis?

Answer 2

CO2+H2O—>C6H12O6+O12
6CO2+6H2O—>C6H12O6+6O2

Question 3

What is photosynthesis?

Answer 3

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar

Question 4

What are the reproductive parts of a flower?

Answer 4

Stamen (male reproductive parts) : anther , filament
Carpel/pistil (female reproductive parts) : stigma , style , ovary , ovule

Question 5

How do plants reproduce?

Answer 5

Step one: After pollen has landed on the stigma, it grows a pollen tube down through the style to the ovary.
Step two: The nucleus of the pollen grain travels down the pollen tube and fertilises the nucleus in the ovule.
Step three: The fertilised ovule develops into a seed. The seed contains the plant embryo, which contains genetic material from both parents. The ovary develops into the fruit.

Question 6

What are the different methods of seed dispersion?

Answer 6

gravity, wind, ballistic, water, and by animals

Question 7

What is gas exchange in plants?

Answer 7

Just like animals plants need to respire to release energy. Therefore they require carbon dioxide to produce energy and oxygen. The stomata opens and closes during day and night
