Questions Related to plant and animal cell
The plant cells central vacuole
-
Provides the plant cell with support
-
Stores nutrients and cellular waste products
-
Is a reservoir for water
-
All of the above
So, the correct answer is 'all of the above'.
Plant cells need a protective cell wall around their cells because
-
they are far more important than the animal cells
-
they cannot move and protect themselves from the extreme weather conditions
-
they are prokaryotic cells
-
None of the above
The Eukaryotic cells, in addition to the nucleus, have many membrane-bound organelles like the mitochondria, endoplasmic reticulum, Golgi bodies etc. Such membrane-bound organelles are absent in the Prokaryotic cells
Casparian Strips are found on the
-
Walls of pericycle cells
-
Walls of endodermal cells
-
Walls of epidermal cells
-
Walls of bundle sheath cells
The barrier between protoplasm and other environment in a plant cell is
-
Cell wall
-
Nuclear membrane
-
Tonoplast
-
Plasma membrane
In the plant cell, plasma membrane and cell wall both are present, both act as a barrier between protoplasm and the outer environment.
A plant cell has
-
Cell wall
-
A number of small vacuoles
-
A few large vacuoles
-
A single central vacuole
-
Both A and D
- A plant cell has a cell wall and single central vacuole.
- Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms.
- Their distinctive features include:
- A large central vacuole
- A cell wall composed of cellulose and hemicellulose
- Specialized cell-to-cell communication pathways known as plasmodesmata
When a plant cell is placed in pure water, it?
-
Expands until the osmotic pressure reaches that of water
-
Becomes less turgid until the osmotic potential reaches that of pure water
-
Becomes more turgid until the pressure potential of cell reaches its osmotic potential
-
Becomes more turgid until the osmotic potential reaches that of pure water
Draw well labelled diagram of the following

In a plant cell, O.P. is equal to?
-
T.P. $-$ D. P.D.
-
D. P. D. $-$ T.P.
-
T.P. $-$ D.P.
-
D. P.D. $+$ T.P.
The inclusion like raphides, druses and sphaeraphides can be mainly found in which of the following cells?
-
Prokaryotic
-
Protozoan cells
-
Hygrophytic plant cells
-
Xerophytic plant cells
Plant cells sometimes form mineral crystals. Calcium carbonate occurs as a mass of crystals around a cellulose core to form cystolith (eg, leaf of Banyan). In several plants, calcium oxalate forms needle-like raphides, prismatic crystals, star-shaped sphaeraphides or Druses or powdery mass named as crystal sand.
The percentage of water in a typical plant cell is about
-
10%
-
20%
-
50%
-
80%
Plants are made up of water, organic and inorganic substances. Water makes the majority of the volume of the plant cell. Water comprises of 80-90 percent of the plant's total weight. Water is used to support the cell structure, for metabolic functions, to carry the nutrients and for photosynthesis.
