NEET is one of the toughest exams a student can give in India. Every topic that holds a certain amount of marks is important for students. Because a single mark difference can lead to a massive decrease in your ranking. Today we are going to discuss plant anatomy MCQs, these questions have previously appeared in NEET exams so it will help you test your preparation.
Which of the following from the given below is considered to be the most primitive in terms of ontogenetically as well as phylogenetically?
How do Monocot leaves grow in nature?
Which of these statements are correct in terms of motor cell property?
We can see the motor cell in the grass.
The cell is quite large in size and is thin-walled colourless.
A motor cell has vacuolated cells on the adaxial surface.
All the above
If a given fruit is grafted using Scion as stock, then the quality of fruits produced will have what type of genotype?
Given below are the list of some plants which of them show multi-epidermis?
What will happen to the marking that has been put on the tree nearly 20 years back?
Height of the sculpture will increase in 20 years.
Due to secondary growth, the name will be erased from the tree.
The height of the carving will be in the exact same location
Height of the carving will decrease.
How does ground grass and Bamboo elongate itself? What does that activity call?
Which of the given chloroplast tissue has the most number
Bundle sheath cells.
What will happen to the roots if the stem of a given plant gets attacked by a girdler?
Roots are going to die first
Shoots of the plant will die first
Both of shoots and roots will die at the same time
Nothing will happen.
Which part of the plant provides us with industrial level jute fibres?
None of these
Where can we see an abnormal secondary growth in the plantation?
Which of the following is made up of the dead cells?
The Pith and the cortex do not at any term differentiate in
The translocation of food takes place by the help of Sieve tubes because of which property?
Sieve tubes don’t have bordered pits
Doesn’t have end walls sticking to it.
Has no border lumen and perforated cross walls
What are Cork cambium and Vascular cambium?
During the process of grafting stock and Scion forms a union but which one of them occurs first?
Formation of callus comes first
Production of plasmodesmata takes place in the beginning
The differentiation of new vascular tissue forms first.
The regeneration of cortex and epidermis
Where do the Casparian bands occur in plants?
A cellular structure which is well organised and differentiated does contain a cytoplasm but does not have any nucleus what is it called?
Which of the following if we expose them to sunlight and air would decay at a much faster rate than others?
As a plant becomes a tree and starts to grow its roots, stems and trunk, which of the following wood from the list below grows at a faster speed than the other three?
Which of the given properties in the below list is not right about Sclereids?
Sclereids are a group of living cells
They are present in nutshells, guava pulp, and pear.
Sclereids are also called stone cells
When they come in contact with fibre they from sclerenchyma
During the stage of vascularisation, what happens in plants?
The differentiation of procambium takes place, after that, the formation of phloem which is followed by primary xylem
differentiation of procambium takes place which is followed by the creation of primary phloem and xylem simultaneously
All three of these occur at the same time.
Differentiation of Procambium which is followed by the formation of secondary xylem.

About Plant Anatomy
Plant anatomy is perhaps the study of structure, size and shape of the plants. So the plant anatomy maily centres around the body parts and the systems that will make the plant. So what is the plant body made up of? Any typical plant body has three main vegetative organs which are the leaf, the root and the stem. Moreover apart from these three organs it also consists of a set of reproductive parts which are seeds, flowers and fruits. Just like a living thing, all the parts of the plant are made up of cells.
Anatomy of Flowering Plants
We can divide the plant tissue into permanent tissue and meristematic tissue. The meristematic tissue is perhaps made of a group of cells that can divide on its own. Likewise these tissues can stretch, expand and differentiate into other kinds of tissue as they get mature. Moreover the meristematic tissues give rise to permanent tissues. However these are Apical meristems, intercalary meristems and lateral meristems.
Know About Permanent Tissues
However the permanent tissues are extracted from the meristematic tissues and do not have the ability to divide. These have got the mature forms and are divided into complex and simple permanent tissue.However the permanent tissues form a significant portion of the plant. It consists of simple permanent tissues and complex permanent tissue.
Simple Permanent Tissue
The simple permanent tissues further consist of parenchyma, sclerenchyma and collenchyma. The parenchyma are the tissues that can be found in the soft parts of the plant like leaves, stems, flowers, roots. The parenchyma tissues will help to store, help in the process of photosynthesis and will also help the plant to float on water.
However the collenchyma is related to parenchyma cells that have thick cell walls. These will help to provide mechanical support to the plant structure like in the petiole of the leaf.
The sclerenchyma cells are dead. These are firm and have thick hard secondary walls.
Complex Permanent Tissue
The complex permanent tissue is divided into xylem and phloem. The xylem is made up of vessels, xylem fibres, tracheids and xylem parenchyma. The vessel and the tracheids have a hollow tube like structures that will help to conduct minerals and water. Moreover the xylem conducts only in a vertical direction. The sieve elements consist of two types namely, sieve tubes and sieve cells.However the phloem has four elements which are phloem parenchyma, sieve tubes, phloem fibres and companion cells. However the phloem regulates in both directions. It helps to transport food from the leaves to the other different parts of the plants.
