Important Notes on Anatomy of Flowering Plants for NEET

If you are studying for a National level exam like NEET, you must learn about important notes of biology for NEET anatomy of flowering plants in great detail. The chapter is vital for NEET aspirants, and one should read the below points carefully. Anatomy is the study of a flowering plant’s internal composition by cutting them into sections. It helps to understand the functioning of plants after careful analysis by anatomists. Reading such concepts can help you crack NEET with flying colors. 

So, remember to study the anatomy of flowering plants PDF along with other chapters. Types of Flowering Plant’s Tissues. While studying the important notes of biology for NEET anatomy of flowering plants, one must also include knowledge of tissues. 

Tissues are a group of cells, belonging to a common origin, and they execute a similar type of function. They can be divided as Meristematic Tissue: These tissues consist of cells that possess the capacity to divide. They exist in specific regions in a plant, and they are of three types, apical, lateral, and intercalary meristem. The below table shows the types and functions of meristems in detail. 

Read them to know more: Types and Functions of Meristems Apical Meristems Intercalary Meristems Lateral Meristems Apical meristems are available in the root’s tips and shoots. They are present within mature tissues. They occur within the mature parts of roots and shoots. 

They can manufacture primary tissues. Similar to apical meristems, they can process primary tissues. They are capable of creating secondary tissues. They play a pivotal role in the growth of a plant’s length.

They can create branches and flowers, also known as axillary buds. They are responsible for secondary growth in plants. 

Permanent Tissue: These tissues are comprised of bundles of cells that do not have the capability of divisibility. They are further categorized into simple and complex tissues. Simple Tissues: They contain a single cell capable of performing the same structure and function. These comprise parenchyma, sclerenchyma, and collenchyma tissues. Parenchymatous tissues comprise cells with a thin cellular wall made of cellulose and intercellular spaces. Sclerenchyma are thick, elongated and narrow dead cells lacking protoplasts. However, collenchyma comprises cells containing chloroplasts at times, with extremely thick corners. 

Complex Tissues: These tissues consist of multiple cells performing different functions in close coordination. 

They are of two types, xylem, and phloem. The xylem contains mostly tracheids, vessels and fibers, responsible for transporting water, whereas phloem consists of sieve tubes, fibers and parenchyma are responsible for transportation of food particles. Notes on the Tissue System, if you are gathering information regarding the important notes of biology for NEET anatomy of flowering plants, you must learn about the tissue system. The tissue system of plants shows its structure and functioning. 

These are responsible for the formation of the outer covering of a plant. The epidermis contains a single layer along with a cytoplasm inside the cellular wall and a vacuole. Found in the stomata and epidermal cells, they aid the process of exchange of gasses and transpiration in plants. Ground Tissue System: These consist of simple tissues like sclerenchyma, parenchyma, and collenchyma. 

Sclerenchyma and collenchyma add mechanical strength to the plants, whereas parenchyma aids storage and photosynthesis. Being produced by ground meristems, they provide strength to plants and synthesize organic compounds. Vascular Tissue System: They contain vascular bundles, which get further divided into xylem and phloem. 

These bundles have the capability of forming secondary tissues due to the presence of cambium in them. They contain radical bundles where the phloem is present on the outer side of the xylem. 

Conjoint ones have both phloem and xylem located on the same radius. 

Did You Know: Guard cells are bean-shaped cells layering on the stomata, and the stomatal apparatus is the aperture present with the guard and subsidiary cells!

Based on the organisation of tissues, roots get divided into two categories. Study the table below to understand them in detail.

Difference Between Dicot Root and Monocot Root

Take Care of Your Health and Concentrate on Studies!

We hope that by going through the above points, you would have an understanding of the important notes of biology for NEET anatomy of flowering-plants. Biology is a vital subject that contains around 90 questions in NEET exam. Therefore, read all the concepts carefully.

Besides, take care of your health while preparing for a National level exam. There is a vast competition every year as lakhs of students appear for the exam, but you should not feel overwhelmed!

6.3 Anatomy of dicotyledonous and Monocotyledonous Plants

6.4 Secondary Growth.

From mosses to Majestic trees there are plants growing all around us. They create most of the food that supports animal life on land. They also produce most of the oxygen that is in the air we breathe. plants are multicellular living things that are mostly grown on land or in freshwater .nearly all plants use the energy from sunlight to turn water and carbon dioxide into Oxygen and sugar a process called photosynthesis .they use the sugar to make Complex materials that form their roots, stems, and leaves. The most primitive type of plant can only grow close to the ground in Damp places but others grow taller and broad covering the land with green vegetation that provides living space and vital food for animals. There are various kinds of plants, flowering plants, and non-flowering plants. In this article, we are going to study the anatomy of flowering plants.

Anatomy of Flowering Plants

Flowers are the sites of sexual reproduction in flowering plants. Their component parts range in the world around the receptacle(tip of the flower stalk ). The sepals (collectively called the calyx) are outermost typically small and green separated from the developing flower. The petals together called the Corolla are generally large and brightly colored, which are found inside the sepals. In monocotyledonous flowers, sepals and petals are indistinguishable individually; they are called tepals. (collectively called perinatal). the petals surround the male and female reproductive structure that is androecium and gynoecium). The androecium consists of stamens( male organs )each stamen is made up of a filament( stalk) and Anther. The gynoecium has one or more carpels; the (female organs) each carpel consists of an ovary, style, and stigma.

Floral Parts of a Flower

A typical flower consists of a stalk, Corolla androecium, and gynoecium. Each of the parts of a flower has a particular role to play. Some flowers may or may not contain one or more of the parts but the same function is done by other parts of a plant.

Portions of a Flower

Stalk: The stalk also known as pedicel is a connection between flower and plant.

Calyx: This is the outermost whorl of the flower.

Corolla: This is a second whorl of the flower andiscomposedcol or Petals.

Androecium: This is the male reproductive part of the flower and it is made up of stamens. 

Gynoecium: This is the female reproductive part of the flower that is the innermost whorl.
