Chloroplasts are green pigment used in the process of photosynthesis found in leaves.
Leucoplasts are colourless and are the storehouse of minerals and other nutrients found in the roots of plants.
Answer:
perharps 200
Explanation:
well since the formula is mass times speed
then it will be 100*2
which is 200
hope this helped in some way
Answer:
D. they will burst
Explanation:
Since the surrounding medium has more water content, the cells will take in water. After some time the cell membrane will burst.
Answer: Option D nutrients
Explanation: at the onset of germination, nutrients is not needed for seed germination. A viable seed has all it it inside of it to grow. For seeds to grow in any environment, they need water, light in some cases, depth of seed planted,temperature in some cases, and oxygen. It is later in it's growth mostly one or 2 weeks that the plant start needing nutrient. Some food crops like vegetables needs nutrients mostly immediately or a day after germination has already occued.
Answer:
CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes.
Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.
Explanation:
CO2 and O2 are highly soluble molecules in water due to their polarizability and their ability to react with water molecules and form new compounds. CO2 is 30 times more soluble in water than oxygen, which also has a high solubility. This ability allows these two molecules to diffuse freely across cell membranes.
Cells promote hydrolysis, that is, the breakdown of ATP molecules when they need to expend energy for any metabolic process, especially when they need to maintain a balance between ion concentrations inside and outside the cell. This is because ATP is a highly energetic molecule and its breakdown promotes energy for the cell to use in its activities.
