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.

FAQs (Frequently Asked Questions)

1. What is the Weightage of Plant Anatomy in NEET?

Plant Anatomy – 3 questions – 12 marks – 6.00% weightage percentage. This might not look like a topic which can help you get lots of scores. But being one of the easy topics you can learn it quickly and any question which comes in the entrance will be like a Godsend to you for improving your marks. 

2. How Many Questions Do Come in NEET Exams?

The NEET exam has a total 180 questions, from these 180, 45 and 45 are given to Physics and Chemistry. The rest of the 90 questions come from Biology. Maximum marks that you could obtain in NEET is 720 marks. 


4 marks will be given to you for every right answer, and -1 will be deducted for every wrong answer. Thus, you need to be careful while providing answers—all these questions you need to solve in 3 hours of time.

3. Differentiate between flowering plants and non-flowering plants?

The flowering plants are a different group of terrestrial habitat plants that produce seeds, flowers and fruits. Moreover these plants are called angiosperms. There are around 300,000 known species of the flowering plants. For example; marigold, rose, lily and many others.


On the contrary, the non-flowering plants are perhaps the other types of plants that carry directly the seeds and do not produce fruits and flowers. These are called gymnosperms. They carry seeds with no covering. For example; redwood, cypress, pine, and many others.

4. Explain the formation and construction of collenchyma?

Collenchyma has cells that are called polygonal. It has thick walls and is simple tissue. The cells are long and have non-lignifies and primary cell walls. The thick walls are made up of pectin, cellulose and hemicellulose materials that have a good amount of water. These can be found in the hypodermis of the herbaceous dicots that are in the form of a homogenous layer or in the inner side of the patches.

5. What is the location and the function of different kinds of meristems?

The meristem is a group of cells that is divided continuously to produce new cells based on location and function. The different kinds of meristems are lateral mersite, apical meristem, intercalary meristem. Its main function is to provide thickness to the plant.


However the apical meristem can be found at the apices of branches, stems and roots and it helps in the growth of the plant.


The intercalary meristem helps to grow the middle position of the plant and is made up of meristematic cells that can be divided in the stem.

6. What do you mean by sieve elements and explain its functions and different types.

The sieve element is the parts of the phloem which helps to conduct and to transport the food materials. The sieve element is divided into sieve tubes and sieve cells. The sieve tubes can be found in angiosperms. The sieve cells are attached to each other which further gives rise to a channel. However the sieve cells can be found in gymnosperms and pteridophytes and these cell walls have holes.

7. What are the different reproductive parts of the flower?

The stamen and pistil form the main reproductive parts of the flower. The stamen is the male reproductive part of the flower and is called Androecium and it is made up of filaments and anther. Whereas the pistil is the female reproductive organ of the flower and is called gynoecium. This is made up of ovaries, stigma and style.
