Answer 1

Answer:

1 leaf

2 bud

3 phloem

4 RBC Red Blood Cellc

5 trachea or spiracles

Answer 2

1. Bryophyllum

• Bryophylum has buds on the edge of it's leaves. When these leaves fall down, the detached buds will start growing separately which is termed as Reproduction.

2. Bud

• Organisms such as Hydra and yeast use regenerative cells for reproduction in the process of budding. The small bulb like projection coming out from the yeast call is called a bud.

3. Xylem

• In plants, minerals and water are transported through the xylem cells from the soil to leaves. The roots cells of xylem obtains ions from soil and creates a difference in the concentration of ions between the roots and soil.

4. RBC (Red Blood Corpuscles)

• Hemoglobin is the iron rich pigment present in RBC(Red Blood Corpuscles) which gives red colour to the blood.

5. Trachea

• Air enters the respiratory system through a series of external openings called Spiracle in insects. These external openings acts as a muscular valves in insects that lead the internal respiratory system and a densely networked array of tubes called trachea.
