Which structure is NOT related to xylem tissue in plants?
- Vessels
- Sieve tubes
- Tracheid
- Xylem fibers
Show answer and explanation
Answer: B. Sieve tubes
Sieve tubes are part of phloem, not xylem, which consists of vessels, tracheids and xylem fibres.

About Transport in Matric Biology
Transport is one of the 15 main chapters in our Federal Board Matric Biology question bank (9th and 10th class), and about 8% of its real questions come from it. Tayyari Karo has 32 real questions on this chapter from 2023 to 2026; 8 are multiple choice and marked instantly, and the rest are short and long questions with a model answer. By difficulty: 25 medium, 7 easy.

Food prepared in leaves is transported by:
- Xylem
- Phloem
- Mesophyll
- Guard cell
Show answer and explanation
Answer: B. Phloem
Phloem transports manufactured food (sugars) from leaves to the rest of the plant.
Which blood component helps in clotting?
- RBCs
- WBCs
- Platelets
- Plasma
Show answer and explanation
Answer: C. Platelets
Platelets (thrombocytes) are responsible for initiating blood clotting at a wound.
Which component of RBCs enables them to carry oxygen?
- Haemoglobin
- Plasma membrane
- Cytoplasm
- Nucleus
Show answer and explanation
Answer: A. Haemoglobin
Haemoglobin binds reversibly with oxygen, allowing RBCs to transport it.
Which artery carries deoxygenated blood?
- Renal
- Pulmonary
- Hepatic
- Carotid
Show answer and explanation
Answer: B. Pulmonary
The pulmonary artery is the only artery that carries deoxygenated blood — from the right ventricle to the lungs.
Which valve prevents the flow of blood from Left Ventricle to Left Atrium?
- Bicuspid valve
- Tricuspid valve
- Semilunar valve
- Pulmonary valve
Show answer and explanation
Answer: A. Bicuspid valve
The bicuspid (mitral) valve, between the left atrium and left ventricle, closes to prevent backflow into the left atrium.
How do wind and humidity affect rate of transpiration?
Show model answer
Wind: increases the rate of transpiration because it continuously blows away the layer of humid air that builds up near the leaf surface, maintaining a steep water vapour concentration gradient between the leaf's interior and the outside air, so more water diffuses out.
Humidity: high atmospheric humidity decreases the rate of transpiration because the air is already nearly saturated with water vapour, reducing the concentration gradient for water to diffuse out of the leaf; low humidity (dry air) increases transpiration.
How are atherosclerosis and arteriosclerosis different from each other?
Show model answer
Atherosclerosis is the narrowing of arteries caused specifically by the buildup of fatty deposits (plaques, mainly cholesterol) on the inner artery walls.
Arteriosclerosis is a broader, more general term for the thickening and hardening/loss of elasticity of artery walls (due to any cause, including ageing, calcium deposition, or atherosclerosis itself). Atherosclerosis can thus be considered one specific type/cause of arteriosclerosis.
