Animal Tissue and Anatomy Questions

Multiple choice evs circulation of blood circulatory system and organs basics of blood and heart transportation in living organisms

The upper chambers of the heart are called

  1. Auricles

  2. Ventricles

  3. Spiracles

  4. Tentacles
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A normal heart has two upper and two lower chambers. The upper chambers, the right, and left atria, receive incoming blood. The lower chambers, the more muscular right, and left ventricles pump blood out of your heart.

So, the correct option is 'Auricles'.

Multiple choice evs circulation of blood circulatory system and organs basics of blood and heart transportation in living organisms

The lower chambers of the heart are called

  1. Auricles

  2. Ventricles

  3. Spiracles

  4. Tentacles
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The upper chambers are called the left and right atria, and the lower chambers are called the left and right ventricles. A wall of muscle called the septum separates the left and right atria and the left and right ventricles. The left ventricle is the largest and strongest chamber in your heart.

So, the correct option is 'Ventricles'.

Multiple choice evs transportation in living organisms circulatory system and organs basics of blood and heart circulatory system

Which of the following is covered by pericardium membrane?

  1. Heart

  2. Kidneys

  3. Small intestine

  4. Stomach
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The serosal pericardium is a closed sac within the fibrous pericardium. It consists of two layers. The visceral layer, called the epicardium, covers the heart and great vessels and is reflected back onto the parietal layer, which lines the interior of the fibrous pericardium.

So, the correct option is 'Heart'.

Iter (Aqueduct of Sylvius) is found between

  1. Third and fourth ventricles

  2. Two lateral ventricles

  3. Lateral ventricles and third ventricle

  4. Rhinocoel and lateral ventricles
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The cerebral aqueduct, or Iter, is a narrow channel that connects the third ventricle to the fourth ventricle in the brain, allowing cerebrospinal fluid to flow between them.

Which one correctly describes the location of body parts in Pheretima?

  1. Two pairs of accessory glands in 1618 segments

  2. Two pairs of testes in 10th and 11th segments

  3. Four pairs of spemathecae in 47 segments

  4. One pair of ovaries attached over septum 1415 segments
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Two pairs of accessory glands are present in 17th and 19th segments. Four pairs of spermathecae are located in 6th-9th segments. They receive and store spermatozoa during copulation. One pair of ovaries is attached at the inter-segmental septum of the 12th and 13th segments.

Two pairs of testes are present on the 10th and 11th segments.
So the correct answer is 'Two pairs of testes in 10th and 11th segments'.

Part of peritoneum that suspends testes is called

  1. Mesentery

  2. Mesorchium

  3. Mesovarium

  4. Renal peritoneum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A mesentery is a double layer of visceral peritoneum. It connects an intraperitoneal organ to (usually) the posterior abdominal wall. It provides a pathway for nerves, blood vessels and lymphatics to travel from the body wall to the viscera.
The mesentery of the small intestine is simply called ‘the mesentery’. Mesentery related to other parts of the gastrointestinal system is named according to the viscera it connects to the mesoappendix.
So the correct answer is 'Mesentery'.
Multiple choice botany plant tissues introduction to tissue tissues - "the teams of workers" introduction to tissues

Tissue means _________________.

  1. Similar cells having common origin

  2. Similar cells having common origin and functions

  3. Cells having same metabolic activities

  4. Similar cells with same metabolic activity
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A tissue is defined as a group of similar cells that have a common origin and perform similar functions. This is the standard biological definition emphasizing both structural similarity (same origin) and functional unity (common function).

Multiple choice botany plant tissues introduction to tissue tissues - "the teams of workers" introduction to tissues

A tissue is a grouping of cells similar in

  1. Function

  2. Structure

  3. Heredity

  4. Origin and function
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
 A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues. The English word is derived from the French tissu, meaning something that is woven, from the verb tisser, "to weave". 
So, the correct answer is 'Origin and function.'
Multiple choice botany plant tissues introduction to tissue tissues - "the teams of workers" introduction to tissues

The tissue is defined as a group of

  1. Cells which are dissimilar in origin, but are similar in form and function

  2. Cells which are similar in origin, but dissimilar in form and function

  3. Cells which are dissimilar in origin, form and function

  4. Cells which are similar in origin, form and function
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In biology, tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues. So, the correct option is "D" (Cells which are similar in origin, form, and function).

Division of cells and tissues is an important factor for establishing a multicellularity in an organism.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In multicellular organisms, most of the tissue of the body is growing by increasing their cell number (means of cell division), but their growth is strictly regulated to maintain a balance between different tissue. Thus, the correct option is A.

Consider the following feature of tissues.

A. They are similar and dissimilar cells.
B. They are performing a common function.
C. They have a common origin.
D. They are characterized by the distinct cell wall.

The correct ones are grouped in

  1. A, B and D

  2. B, C and D

  3. A, B and C

  4. A, C and D
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • A tissue is the group of cells of the common origin that are structurally similar or sometimes dissimilar and perform a particular function. 
  • Only plant cells are characterized by the distinct cell wall and absent in animal cells.

Therefore, the correct answer is option C.
