Multiple choice tissues of animals tissues: plant and animal tissues animal tissues structure of living organisms biology cell division in embryo development division for growth and reproduction

Which type of tissue forms glands

  1. Epithelial

  2. Connective

  3. Nervous

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

Epithelial tissues form the covering of all body surfaces, lines body cavities and hollow organs, and are the major tissue in glands. 

So, the correct answer is 'Epithelial' .

Pseudo stratified epithelium is present in

  1. Urinary bladder

  2. Nephron

  3. Larynx

  4. Trachae
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pseudostratified columnar epithelium lines the respiratory tract, including the trachea (misspelled as 'Trachae' in options). This epithelium appears stratified but all cells contact the basement membrane, with cilia that move mucus.

Which of the following statement is $NOT$ $CORRECT$ about the compound epithelium?
I.   It consist of several layers
II.  It covers the dry surface of the skin, the moist surface of buccal cavity, inner lining of ducts of salivary glands and pancreatic ducts
III.  It provides protection against chemical and mechanical stresses 
IV.  Being multilayered it has a great role in secretion and absorption

  1. Only III

  2. Only IV

  3. Only I and IV

  4. Only II
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Compound epithelium has a limited role in secretion and absorption. So, the correct option is "only IV".

Our outer layer of skin is an example of which type of tissue?

  1. Muscular

  2. Epithelial

  3. Connective

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

Our outer layer of skin is made up of epithelial tissues. The epidermis is composed of the outermost layers of cells in the skin.

The epithelial tissue present on the inner surface of bronchi oles and fallopian tubes is :

  1. Squamous

  2. Cuboidal

  3. Glandula

  4. Cilia ted
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bronchioles and fallopian tubes require ciliated epithelium to move particles or ova. Cilia beat rhythmically to transport mucus in respiratory tract and egg cells in the female reproductive tract.

The cell junctions namely tight, adhering and gap junctions are found in ______________.

  1. connective tissues

  2. epithelial tissues

  3. neutral tissues

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

Cell junctions are proteins that connect the cytoplasmic content of adjacent cells, they form a barrier between two cells and also hold or adhere cell together or with the extracellular matrix. these are abundant in epithelial tissue.

So, the correct answer is 'epithelial tissues'

Read the following statements regarding different types of animals tissues and select the incorrect ones.
(i) Each fasciculus (or bundle of muscle fibres) is surrounded by an epithelial tissue covering called perimysium
(ii) Multi unit smooth muscles are present in ciliary and iris muscles in the eyes and muscles of the walls of large blood vessels.
(iii) Columnar epithelium present in gastric glands, intestinal glands and pancreatic lobules, has a secretory role and is called as glandular epithelium.
(iv) Epithelial tissue arises only from the ectoderm of embryo and is usually supplied with blood vessels

  1. (i) and (iii)

  2. (ii) and (iii)

  3. (ii) and (iv)

  4. (i) and (iv)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Each fasciculus (bundle of muscle fibres) is surrounded by a connective tissue sheath called perimysium. Epithelial tissues arise from all the three primary germ layers of the embryo i.e., ectoderm, mesoderm and endoderm.

Cell cycle was divided into  four stages i.e. G$ _1$, S, G$ _2$, M by

  1. W. Flemming

  2. Strass burger

  3. Howard and Pelc

  4. Farmer
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Howard and Pelc divided cell cycle in four stage. The cell cycle is an ordered set of events, culminating in cell growth and division into two daughter cells. Non-dividing cells not considered to be in the cell cycle. The stages  are G$ _1$-S-G$ _2$-M. The G$ _1$ stage stands for "GAP 1". The S stage stands for "Synthesis". This is the stage when DNA replication occurs. The G$ _2$ stage stands for "GAP 2". The M stage stands for "mitosis", and is when and cytoplasmic division occur.

  2. A-3, B-1, C-2, D-4

  3. A-4, B-3, C-2, D-1

  4. A-1, B-2, C-3, D-4

  5. A-3, B-1, C-4, D-2
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Sphaerosomes are single half unit membrane covered small spherical organelles which synthesize and store fats. The cell wall of bacteria is made up of glycocalyx (carbohydrate and amino acids). Chloroplasts are eukaryotic plant cell organelles which have an internal thylakoid membrane system. The thylakoid membranes carry out the light reactions part of photosynthesis. The chromosomes of a eukaryotic cells are called its karyotype. The diagrammatic representation of a cells karyotype is called an idiogram.
