plant

Question 1

what are the products of photosynthesis

Answer 1

glucose and oxygen

Question 2

how does the carbon dioxide enter the plant

Answer 2

carbon dioxide enters the plant through the holes in the leaves called the stomata

Question 3

how does water enter the plant

Answer 3

water diffuses into the plant through the roots from the soil and travels up the stem via the xylem

Question 4

What is the chemical equation for glucose

Answer 4

C6H12o6

Question 5

why is photosynthesis an endothermic reaction

Answer 5

because it requires energy to be transferred from its surroundings

Question 6

what is the purpose of the vascular bundle

Answer 6

to transport water and sugar

Question 7

what is the purpose of palisade mesophyll

Answer 7

packed with chlorophyll and chloroplast which is where photosynthesis occurs

Question 8

what is the purpose of the cuticle and epidermis

Answer 8

the waxy cuticle, produced by the epidermis cells, seals up the leaf to stop it from drying out

Question 8

what is the purpose of the spongy mesophyll

Answer 8

plenty of space, allows the movement for CO2

Question 9

what is the purpose of a stomata

Answer 9

to let the gas in and out of the leaf and to prevent bacteria from getting into the leaf

Question 10

why do plants need potassium

Answer 10

for healthy plants and flowers

Question 11

why do plants need magnesium

Answer 11

to make chlorophyll

Question 12

what factors affect the rate of photosynthesis

Answer 12

light intensity, carbon dioxide concentration, amount of water, temperature

Question 13

bubbles are produced by water and plants. What gas are these bubbles made up of

Answer 13

The bubbles are made up of oxygen. We know this because oxygen is a product of photosynthesis

Question 14

what is the law of conservation of mass

Answer 14

matter can’t be destroyed or created. It always stays the same

Question 15

what do all carbohydrates have in common

Answer 15

they all provide energy

Question 16

what is the word equation for photosynthesis

Answer 16

carbon dioxide + water —–> glucose + oxygen in the presence of sunlight

Question 17

where exactly in the plants does photosynthesis take place

Answer 17

chloroplast

Question 18

do you think variegated leaves are efficient at converting sunlight into starch

Answer 18

variegated leaves have a weaker green pigment in some areas. The green pigment comes from chlorophyll, which is responsible for converting sunlight into glucose then starch. So because, with a lack of chlorophyll, variegated leaves are not efficient at converting sunlight to starch.

Question 19

what are the characteristics of all living organisms

Answer 19

MRS GREN : movement, respiration, sensitivity, growth, reproduction, excretion and nutrition

Question 20

what do the roots do

Answer 20

the roots absorb water and inorganic nutrients

Question 21

what does the leaf do

Answer 21

performs photosynthesis

Question 21

what does the stem do

Answer 21

supports the plant

Question 22

what is the purpose of transpirtation

Answer 22

to control the temperature and the flow of nutrients to the leaves in a plant

Question 22

how are decomposers important to plants

Answer 22

decomposers feed on dead things around plants. They break apart the dead materials and make the vital nutrients for plants, this will help the plants grow.

Question 23

what is the process of plant losing water called

Answer 23

transpiration

Question 24

why is transpiration important for plants

Answer 24

because it stores water for the plant when there isn’t enough water

Question 25

what does it mean when guard cells become flaccid

Answer 25

it means that there is little water in the soil, and the cells have decreased in size because of the loss of water.

Question 26

what does it mean when guard cells are turgid

Answer 26

it means that there is a lot of water in the soil for the cells to soak up and the cells become larger and open
