Plant Resources

Question 1

What are the plants resources?

Answer 1

Solar radiation, Water, Minerals and Carbon dioxide.

Question 2

What accounts for 50% of photosynthesis on Earth?

Answer 2

Photosynthesis Alage.

Question 3

In basic terms, what does photosynthesis do?

Answer 3

It takes light energy and converts it into chemical energy.

Question 4

What does photosynthesis do?

Answer 4

Photosynthesis uses water, carbon dioxide and solar radiation to convert oxygen and sugars for fuel.

Question 5

What is a resource depletion zone?

Answer 5

This is when for example leaves cover rain, solar radiation.

Question 6

What is PAR, the meaning and explanation?

Answer 6

Photosynthetically active radiation which is what light spectrum is used for photosynthesis.

Question 7

What are the tiny pores in plants called which release water?

Answer 7

Stomata.

Question 8

How do plants acquire carbon dioxide?

Answer 8

They must open their Stomata.

Question 9

What happens if a plant gains too much water?

Answer 9

The plant will wilt and die as it will trade photosynthesis for water loss.

Question 10

Is it true or false that desert plants generally only Photosynthesis with water and if so, explain?

Answer 10

Because the desert is so hot, solar radiation is constant. Water Photosynthesis allows plant not to over photosynthesis but also allows stores energy incase of possible drought.

Question 11

Plants that live long often drop leaves. Explain?

Answer 11

Long lived plants produce leaves when it is wet and drop them in droughts due to lack of water supply. My guess to this would be so that plants can gain more solar radiation, water and carbon dioxide for photosynthesis sugar and during a drought, the leaves are dropped in order for the plant to survive, not using excess amounts of energy on a limited amount/ low amount of energy.

Question 12

In terms of photosynthesis, what is an advantage to increase Co2 and a disadvantage?

Answer 12

Advantage is that co2 increases photosynthesis, however a disadvantage is that plants lose a lot of nutrients due to less nitrogen.

Question 13

What plays an important role in a plants nutrition?

Answer 13

Nitrogen.

Question 14

What term describe how plants make their own food?

Answer 14

Autotrophs.

Question 15

How do plants make their own food?

Answer 15

Through photosynthesis, they’re known at autotrophs.

Question 16

What is nitrogen important for in plants and where does it come from?

Answer 16

Nitrogen is needed to create protein for plants, as well as many nutrients and gets nitrate ions from the soil.

Question 17

Explain what happens when a plant has very little nitrate ions?

Answer 17

No protein ca be created from nitrogen and nutrients will be low.

Question 18

Explain why is magnesium important to a plant?

Answer 18

Magnesium is needed to make chlorophyll which is the green pigment in leaves, the light is absorbed in chloroplasts and if there is lack of magnesium, the chlorophyll will not be there, lacking chloroplasts and stunting the growth.

Question 19

What is a chloroplast?

Answer 19

A plastid in which photosynthesis occurs.

Question 20

What is a plastid?

Answer 20

A small organelle within a cell.

Question 21

Explain why farmers rotate crops fields?

Answer 21

To get a good mix of nutrients as different crops have varying levels and accounts of nutrients.

Question 22

Why might a plants veins turn yellow?

Answer 22

a phosphate deficiency.

Question 23

Why does a phosphate deficiency in a plant cause possible stunted growth?

Answer 23

Because phosphate assists in transporting energy (from roots).

Question 24

Explain what NPK stands for and what it does?

Answer 24

It is a fertiliser used by farmers and contains, Nitrogen, Phosphorus and Potassium.

Question 25

Is chlorophyll a plastid or pigment?

Answer 25

It is green pigment in the leaves.

Question 26

What organelle within a plant causes photosynthesis?

Answer 26

Chloroplasts.

Question 27

What are two natural fertilisers?

Answer 27

Manure and slurry from cattle farms.

Question 28

Why are natural fertilisers good for farms?

Answer 28

Because the urine and scat contain a lot of nutrition for growth.

Question 29

What is the difference between organic and inorganic?

Answer 29

Organic compounds have carbon atoms whilst inorganic compounds do not have carbon atoms.

Question 30

What’s the term which describes organisms which get nutrients from organic substances?

Answer 30

Heterotroph.

Question 31

What’s the term which describes fungus, plants or microorganisms which feed on dead or decaying organic matter?

Answer 31

Saprophyte (They are like scavengers and will feed on what is left over).

Question 32

What is a grazer?

Answer 32

In basic, when an organism eats prey which isn’t killed such as a cow eating grass.

Question 33

What is the term that describes organisms which eat prey but are not killed?

Answer 33

Grazers.

Question 34

What’s two forms of predators where the prey is not killed?

Answer 34

Parasitism and grazers.

Question 35

Explain the difference between Endo and Ectoparasites?

Answer 35

Endo parasites are within (live within cell), ectoparasites live outside of the body in a host such as ticks, mites fleas, leeches.

Question 36

What is the term that describes animals which can feed on various foods?

Answer 36

Polyphagous.

Question 37

Explain the difference between a generalist and specialist?

Answer 37

Generalist can feed on various foods (polyphagous) and a specialist only eats certain parts of the food such as seeds.

Question 38

Are short lived organisms generally specialists or generalists?

Answer 38

Short lived organisms tend to be specialist whereas long lived organisms tend to be generalists (or polyphagous).

Question 39

What is an advantage and a disadvantage to an organisms being a specialist?

Answer 39

Advantage is that the structure of the organism will be well suited to the task of for example, getting food.
Disadvantage is that if the food that the organisms has become accustomed to be a specialist towards is endangered, the organism will have a difficult time with getting other food.

Question 40

Explain the difference in terms of energy between a heterotroph and an autotroph?

Answer 40

Heterotrophs cannot produce their own energy.

Autotrophs can produce their own energy.

Question 41

Describe the two types of autotroph?

Answer 41

Photoautotroph perform photosynthesis to convert sunlight into glucose

Chemoautotroph which organisms use energy from chemicals into glucose (energy comes from inorganic reactions)

Question 42

Describe the types of Heterotroph?

Answer 42

Consumers which are herbivore, carnivore and omnivore

Decomposers which are detritivores (animals which feed on dead organic matter) and saprophyte (Plants, fungi and microorganism which feed on organic chemicals)

Question 43

Explain what coevolution is?

Answer 43

When an evolution in a species has an impact on evolution in other species, for example, is cat was to evolve to eat a certain plant, that species of plant may also evolve defensive spike in order to stop the cat from eating the plant so that the plant can survive.

Question 44

Describe an example to how evolution to toxins could be beneficial to a moth?

Answer 44

If a moth can become resilient to toxins from a certain plant, the moth could eat that plant, have the toxins in their body which will stop predators from wanting to eat the moth due to the toxins.

Question 45

What term describes animals which evolve camouflage?

Answer 45

Cryptic colouration.

Question 46

What is the term which tells predators that an insect is dangerous due to its colours?

Answer 46

Aposematic colouration, also known as mimicry.

Question 47

What is mimicry?

Answer 47

Aposematic colouration, which means, animals and organisms will have bright colours such as bright blue to warn others that they are dangerous.
