Answer:

chloroplasts

Explanation:

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

The chemical energy of these plants all started with what energy source?

Zielflug [23.3K]

Answer:

Sun(solar energy)

Explanation:

The sun is the ultimate source of energy in our solar system.

The chemical energy in plants all started out with solar energy from the sun.

During the process of photosynthesis;

green plants manufactures their food using sunlight.
in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.

Photosynthetic reaction simply converts solar energy from the sun into chemical energy.

Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.

The specific heat of iron is 0.11 cal/goC. A cafeteria fork made of iron has a mass of 20 grams. How much heat energy is needed

Natasha2012 [34]

Hello!

To solve this problem you need to use the following equation for heat transfer to calculate the heat added (Q) and substitute in this equation the values for specific heat (c), mass (m) and temperature difference (ΔT). The following equation describes the heat needed to raise the temperature of a given object:

$Q=c*m*ΔT=(0,11cal/g°C)*(11g)*(75°C-25°C)=121 cal$ :

So, to heat the cafeteria fork made of iron with a mass of 20 grams from 25 °C to 75°C, you'll need 121 cal of heat energy.

How does the placement of the mica sheet and the direction of light affect the growth of a plant?

Sladkaya [172]

Answer:

Explanation:

When the mica plate was inserted on the illuminated side, the plant did bend towards the light. Therefore, the chemical signal was a growth stimulant because the phototropic response involved faster cell elongation on the shaded side than on the illuminated side.
