Gabbro and basalt are two igneous rocks having the same chemical composition, and the same minerals (plagioclase feldspar + pyroxene), but are of different origins. Gabbros form at depths and cool slowly, whereas basalts are volcanic rocks that crystallize rapidly at the surface of the earth.

Key Takeaways: Plant Tissue Systems
Epidermis is a thin cell layer that covers and protects underlying cells. The outer periderm, or bark, is a thick layer of nonliving cork cells. Vascular tissue is composed of xylem and phloem. These tube-like structures transport water and nutrients throughout the plant.
They are all Rr so
The entire generation will have smooth seeds.
Answer: The only reaction performed by chloroplast through its chlorophyll is photosyntesis. Therefore the chemical formular is below.
C02 + H20 → C6H1206 + O2+ H20.
(carbondioxide) + (Water) Chlorophyll (glucose) +(oxygen)+ (water)
and
enzymes .
This is the single reaction of the process of photosynthesis.However two interconnected reactions are involved light dependent stage and light independent stage.
The first reaction takes place in presence of sunlight, and it is called Photolysis of water.it is the spiting of water to H+, electrons and Oxygen. This is the source of oxygen seen above.
4 H20→ 4H+ + 4e- + 02.
The light independent stage; the hydrogen ion from the photolysis is transfer to the light independent stage to reduce the C02 to produce glucose.In the first equation seen above.
Since chloroplast performs photosynthesis through action of its chlorophyll, The above reaction describes the chemical formula.
B.
The cell wall of plants is made up of the middle lamella, the primary cell wall and the secondary cell wall .
<u>Cellulose</u><u> a complex carbohydrate is the major components</u>. It contains, monomers of glucose in small units linked to one another by bonds.
C
Vacuole helps in plant turgidity needed for uprightness. when filled with water provides turgor pressure increases as the cell membrane pushes against the cell wall. The resulted turgidity helps the plants to maintain resistance to external pressure and therefore resist the effects of gravity.
Answer:
The correct answer would be B) homologous.
Homologous organs refer to the set of organs which have different appearance and function but share common anatomy due to common ancestry.
For example, the forearm of human, forelimb of the horse, wing of a bat, wings of birds, and seal's flipper share common underlying anatomy. They are made up of same sets of bones (humerus, radius, ulna, carpels, metacarpals, and phalanges).
These organs are adapted to perform different functions in an environment.
It is also observed that these organs developed in the same manner in the embryo and from similar origins.
