Questions Related to cell structure and micro-organisms
Which cell organelles is absent in an animals cell?
-
A nucleus
-
A cell wall
-
A large vacuole
-
Both B and C
The animal cells are the eukaryotic cells which are composed of well-developed cell organelles. The animal cell can be differentiated from the plant cell due to the absence of certain structures in the cell. The cell wall is absent in the animal's cells and they have only the cell membrane. The vacuole is present in the plant cell for storage and absent in the animal cells.
Animal cells are
-
Round and irregular in shape
-
Round or rectangular in shape
-
Regular and rectangular in shape
-
Irregular and square in shape
The main difference between an animal cell and a plant cell is that plant cells have a cell wall and animal cell lacks the cell wall. The cell wall which is made up of cellulose gives the plant cell rigidity resulting in a fixed, rectangular shape. Animal cells lack the rigidity hence, they tend to have a round and irregular shape. Animal cells tend to vary greatly in appearance. The cell wall allows high pressure to build inside of the plant cell without bursting. Due to this, the plant cell is able to accept large amounts of liquid through osmosis without bursting. Animal cells, which only have a thin membrane restricting access to the cell, tend to burst if they absorb too much extra water.
Animal cell is limited by
-
Plasma membrane
-
Cell membrane
-
Basement membrane
-
Both A and B
The cell wall is absent in an animal cell. The plasma membrane is a biological membrane that separates the interior of animal cells from the outside environment. The basic function of the plasma membrane is to protect the cell from its surroundings. The cell membrane is also known as plasma membrane.
Which of the following is useful for the study of a typical animal cell?
-
Blood cell
-
Hair cell
-
Skin cell
-
Human cheek cell
Which of the following is absent in an animal cell?
-
Cytoplasm
-
Nucleus
-
Cell membrane
-
Cell wall
The plants and the animal cells are the eukaryotic cells which are composed of well-developed cell organelles. The animal cell can be differentiated from the plant cell due to the absence of certain structures in the cell. The cell wall is absent in the animal's cells and they have only the cell membrane.
Which of the following life processes does not take place in animal cells?
-
Movement
-
Respiration
-
Excretion
-
Photosynthesis
The animal cells lack the cellular organelle chloroplast. The chloroplast or the chlorophyll pigments are required for carrying out photosynthesis by capturing solar energy. The animal cells devoid of this organelle cannot perform photosynthesis.
Cell wall is absent in which of the following?
-
Plants
-
Animals
-
Mucor
-
Bacteria
Plants, algae, fungi, bacteria and some archaea have cell walls but animals and protozoa do not have cell walls. Animal cells have plasma membrane.
Which of the following organelles is found in plant cells but not in animal cells?
-
Nucleus
-
Mitochodrion
-
Chloroplast
-
Golgi apparatus.
Interconvertible organelle in plant cell is
-
Plastids
-
Vacuole
-
Mitochondria
-
Lysosome
Select the wrong statement from the following.
-
The chloroplasts are generally much larger than mitochondria
-
Both chloroplasts and mitochondria contain an inner and an outer membrane
-
Both chloroplasts and mitochondria have an internal compartment, the thylakoid space bounded by the thylakoid membrane
-
Both chloroplasts and mitochondria contain DNA
