plant nutrition

Question 1

photosynthesis

Answer 1

a process which green plant use carbon dioxide and water to produce oxygen and glucose with the presence of sunlight

Question 2

chemical equation

Answer 2

6co2+6h2o=c6h12o6=6o2

Question 3

carbon enter leaf and water enter root

Answer 3

by diffusion and osmosis

Question 4

chlorophyll

Answer 4

green pigment found in chloroplasts
which trap light energy and convert it into chemical energy
light energy breakdown water into h atom and o atom the o atom diffuse out

Question 5

use of glucose

Answer 5

to releases energy during respiration
form cellulose cell wall
convert sucrose into starch in leaves
reacts with nitrate to for amino acid
form fats

lamina petiole branch and mid rib

Question 8

internal part of leaves

Answer 8

upper epidermis- cuticle epidermal cell
mesophyll- palisade mesophyll cell spongy mesophyll cell vascular bundle
lower epidermis- guard cell stomata

Question 9

element for growth

Answer 9

carbon hydrogen oxygen phosphorus and potassium

Question 10
