Multiple choice biology cell structure and micro-organisms plant and animal cell cell structure organisation of the organism

The outer covering in addition to cell membrane in plants is called as 

  1. Plasmalemma

  2. Capsule

  3. Cell wall

  4. Both A and B
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The cell wall is a tough, flexible and sometimes rigid layer that surrounds some cells e.g., plant cells. It surrounds the cell membrane and provides these cells with structural support and protection. In addition, the cell wall acts as a filtering mechanism. Animals do not have a cell wall.

The ................. allows high pressure to build inside of the plant cell without bursting.

  1. Cell wall

  2. Cytoplasm

  3. Nucleus

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

The cell wall allows high pressure to build inside of the plant cell without bursting. The plant cell is able to accept large amounts of liquid through osmosis without bursting. This is due to the presence of cell wall which is absent in the animal cell.

A mature plant cell has

  1. Cell wall and protoplasm

  2. Protoplasm and vacuole

  3. Vacuole and cell wall

  4. Protoplasm, cell wall, and vacuole
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The protoplasm can be defined as a material which comprises of the living part of the cell including the cytoplasm, nucleus and other organelles. Plant cells are characterized by the presence of large vacuoles and cell wall, which are not seen in animal cells
So, the correct answer is 'Protoplasm, cell wall, and vacuole'.

Cellular totipotency is demonstrated by

  1. Only gymnosperm cell

  2. All plant cells

  3. All eukaryotic cell

  4. Only bacterial cells
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cellular totipotency is the ability of a single cell to divide and produce all the differentiated cells in an organism. In plants, this is a general property of most living parenchymatous cells.

Which cell organelle is absent in the leaves of onion?

  1. Nucleus

  2. Cell wall

  3. Centriole

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

Plant cells, including onion leaves, lack centrioles, which are typically found in animal cells and lower plants for spindle organization during cell division. Nuclei, cell walls, and endoplasmic reticulum are all present in plant cells.

Multiple choice biology organisation of the organism membrane bound organelles cell: size and differentiation microscopy

Select the set of cell organelles that are the part of endomembrane system:
(i) Endoplasmic reticulum
(ii) Golgi body
(iii) Mitochondria
(iv) Chloroplast
(v) Microbodies
(vi) Lysome
(vii) Vacuole.

  1. i, ii, iii, v, vi

  2. i, iv, vi, vii

  3. ii, v, vi, vii

  4. i, ii, vi, vii
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The endomembrane system includes organelles whose functions are coordinated, specifically the endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles. Mitochondria and chloroplasts are semi-autonomous and not part of this system.

Which is wrong

  1. Both chloroplast and mitochondrion has an internal compartment or thylakoid space bounded by thylakoid membrane

  2. Both contain DNA

  3. Chloroplast is generally larger

  4. Both are covered by double membrane.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Chloroplasts have thylakoids, but mitochondria do not. Mitochondria have cristae, which are folds of the inner membrane, not thylakoids.
