Plant nutrition

Question 1

What is photosynthesis?

Answer 1

Process by which plants sythesize carbonhydrates from raw materials using light energy

Question 2

State the name equation for photosynthesis

Answer 2

carbon dioxide+water-> glucose +oxygen

Question 3

what presence does there need to be for photosynthesis to take place

Answer 3

light
chlorophyll

Question 4

what is the balenced symbol equation for photosynthesis

Answer 4

6CO2 + 6H2O->C6H12O6+6O2

Question 5

What is chlorophyll

Answer 5

green pigment found in chloroplasts which transfers energy from light into energy in chemicals, for the synthesis of
carbohydrates

Question 6

what is the function of chlorophyll

Answer 6

it transfers energy from the light into energy in chemicals for tge synthesis of carbohydrates

Question 7

Explain the importance of: nitrate ions

Answer 7

They contain nitrogen for making amino acids and proteins. These are needed for cell growth.

Question 8

What happens if a plant can’t get enough nitrates?

Answer 8

It will be stunted and older leaves will turn yellow

Question 9

What are the 3 main mineral ions plants need for growth

Answer 9

Nitrates, Phosphates and potassium

Question 10

What is a mineral ion plants need but in small amounts?

Answer 10

Magnesium

Question 11

Explain the importance of:
magnesium ions

Answer 11

Magnesium is required for making chlorophyll which is needed for photot

Question 12

What happens when plants don’t get sufficient amounts of magnesium ions?

Answer 12

Leaves will turn yellow

Question 13

Investigate the need for chlorophyll, light
and carbon dioxide for photosynthesis, using
appropriate controls

Question 14

Investigate and describe the effects of varying
light intensity, carbon dioxide concentration and
temperature on the rate of photosynthesis

Question 15

Investigate and describe the effect of light and
dark conditions on gas exchange in an aquatic
plant using hydrogencarbonate indicator solution

Question 16

Identify and explain the limiting factors of
photosynthesis in different environmental
conditions

Answer 16

photosynthesis is a complex process that can be limited by various environmental factors such as light intensity, carbon dioxide concentration, temperature, water availability, and nutrient availability. Therefore, it is essential to maintain suitable environmental conditions to ensure optimal rates of photosynthesis in plants.

Question 17

use and storage of starch

Answer 17

energy store

Question 17

use and storage of starch

Answer 17

energy store

Question 18

use and storage of cellulose

Answer 18

to build cell walls

Question 19

use and storage of glucose

Answer 19

used in respiration to provide energy

Question 20

use and storage of sucrose

Answer 20

for transport in the phloem

Question 21

use and storage of nectar

Answer 21

to attract insects for pollination

Question 22

Describe the physical features of typical leaves

Answer 22

most leaves have a large surface area
and are thin

Question 23

How are the features of most leaves adapted for photosynthesis

Answer 23

Large surface area and thinness: These features allow for a greater amount of light to be absorbed by the leaf, as well as a shorter distance for carbon dioxide to diffuse into the leaf and oxygen to diffuse out.

Question 24

how do chloroplasts adapt leaves for photosynthesis

Answer 24

organelles that contain chlorophyll and are responsible for photosynthesis

Question 25

how does the cuticle adapt leaves for photosynthesis

Answer 25

a waxy layer that covers the epidermis of the leaf, which helps to reduce water loss through transpiration

Question 26

how do the guard cells and stomata adapt leaves for photosynthesis

Answer 26

specialized cells that regulate gas exchange and water vapor loss through small openings on the underside of the leaf

Question 27

how does the upper and lower epidermis adapt leaves for photosynthesis

Answer 27

layers of cells that protect the inner parts of the leaf

Question 27

how does the palisade mesophyll adapt the leaves for photosynthesis

Answer 27

a layer of elongated cells packed with chloroplasts, which are responsible for most of the photosynthesis in the leaf

Question 28

how does the spongy mesophyll adapt the leaves for photosynthesis

Answer 28

a layer of loosely packed cells with air spaces in between, which facilitate gas exchange

Question 29

how do air spaces adapt the leaves for photosynthesis

Answer 29

small gaps in the spongy mesophyll that allow for the diffusion of gases

Question 30

how do vascular bundles adapt leaves for photosynthesis

Answer 30

structures that contain xylem and phloem tissues for the transport of water and nutrients

Question 31

how does the xylem adapt leaves for photosynthesis

Answer 31

a tissue that transports water and minerals from the roots to the rest of the plant

Question 32

how does the phloem adapt leaves for photosynthesis

Answer 32

a tissue that transports sugars and other organic molecules from the leaves to other parts of the plant.
