Multiple choice examples of bryophytes plant kingdom biology

Which of the following is not a part of moss capsule?

  1. Operculum

  2. Peristome

  3. Annulus

  4. Protonema

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The sporophytes of mosses, like those of the liverworts, consist of a foot, seta and capsule and remain permanently attached to the gametophytes. At the tip of the capsule is a lid (operculum) which, prior to spore dissemination, falls away exposing the so-called peristome teeth, a set of structures, often delicate and thread-like in appearance, that form a ring around the mouth (rim) of the capsule. The peristome teeth are perhaps the most characteristic feature of the mosses; usually composed of cell wall remnants, they respond to changes in the humidity of the atmosphere. When a moss first grows from the spore, it grows as a protonema, which develops into a leafy gametophore.

A Correct answer
Explanation

The vocal cords are located inside the larynx, which is the organ in the neck involved in breathing, sound production, and protecting the trachea against food aspiration.

Multiple choice
  1. Digestive system

  2. Lymphatic system

  3. Excretory system

  4. Endocrine system

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The lymphatic system collects excess interstitial fluid and returns it to the venous system (misspelled as 'Venus system') near the subclavian veins, helping to maintain blood volume.

Multiple choice

B Correct answer
Explanation

The Loop of Henle is a U-shaped portion of the nephron, which is the functional unit of the kidney. It plays a critical role in concentrating urine and conserving water in the body.

Multiple choice
  1. Uvula

  2. Epiglottis

  3. Tongue

  4. Oesophagus

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The epiglottis is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx. It acts as a lid, closing off the windpipe during swallowing to prevent food and liquid from entering the lungs.
